Oil pump Shtil 180: device, breakdowns, replacement

Repair tools Shtil 180

To carry out a relatively high-quality repair of the Shtil MS 180 chainsaw yourself, you will need to have:

air compressor (for cleaning the chainsaw and blowing out the main components and assemblies);
a vacuum gauge is necessary to check the tightness of the crankcase and carburetor, as well as to identify defective seals;
piston stopper to limit the stroke of the crankshaft;
electronic tachometer in order to correctly adjust the chainsaw carburetor;
T-key STIHL Torx 27 or equivalent;
puller for crankshaft bearings.

Only if you have these tools, do-it-yourself repair of a Shtil 180 chainsaw can be done with sufficient quality.

Chainsaw pump repair

There is a worldview that repairing a chainsaw oil pump with your own hands is quite problematic. In fact, if you have basic locksmith skills and general concepts and rotating mechanisms, you can effortlessly return its initial characteristics. To do this, you need to prepare the following tools and accessories:

Set of figured and flat screwdrivers;
Open end wrenches and socket heads;
Rags.

To eliminate defects in the pump, you need to dismantle it without touching the working part.

Installed oil pump on a chainsaw

Between the two halves of the unit there should be a sealing gasket, which in the presence of gusts and changes in height will need to be replaced with a new one. The next step is to check the integrity of the supply hose. Its cylindrical generatrix should be free of diaper rash and cracks, which in the future could lead to a loss of system density. If such lines are identified, it is necessary to change the lines, and wash a good hose and install it with sealant to the ends of the tank and pump.

The output channels of the oil pump do not have to have foreign inclusions (dust, chips, dirt). Such blockages can lead not only to a deterioration in the lubrication process and the formation of vacuum plugs that can destroy the supply lines.

How to Replace the Starter Cord

Quite often the starter cord needs to be replaced due to a break. Let's figure out how you can replace it without contacting a service center.

Removing the starter from the Shtil 180 chainsaw is quite simple, without even removing the handle block; to do this, you will need to unscrew the mounting screws and remove the covers of the oil and fuel tanks. Then, slightly lifting and turning the starter, remove it from its seat.

The starter cord is wound on a special drum, which is installed in the body of the part. To replace the cord, there is no need to remove the drum; just remove the broken cord and wind a new one.

After the cord is wound on the drum, it is necessary to pass it through the starter body and install the handle and secure it with the help of several knots made one after another. Next, the working stroke of the starter is checked, and if everything is in order, the part is installed in place.

A video showing how to replace the starter cord yourself can be viewed below. The master comments in detail on all stages of the replacement, starting from removing the starter and ending with installation.

Operational and technical characteristics

As for the technical and operational characteristics of this chainsaw, they are in many ways superior to all modern market analogues. Find out how to properly break in a chainsaw here.

The design of the Stihl 180 chainsaw is manufactured in such a way as to achieve maximum impressive results, without causing any discomfort during operation. The device is completely vibration-free and does not tire the operator’s hands.

STIHL MS 180

The handle that surrounds this tool sits tightly on 3 shock-absorbing blocks made of rubber, which is also very convenient for using a chainsaw.

Chainsaw Shtil ms 180 has the following specific characteristics:

The maximum working volume is 31.8 cm³;
Nominal weight is only 3900g;
Power level is 1.5 kW / 2.0 hp;
Tire 0.35 m long;
Characteristic Oilomatic type chain with a pitch of 3/8 “P (PMC3);
Tank with a volume of 250 cm³;
Idle speed is 2800 rpm;
Specific gravity – 2600 g/kW;
The permissible vibration level is 6.6 to the left and 7.8 m/s2 to the right;
Sound pressure is 97.0 dB;
Sound power – 106.0 dB.

It is easy to operate and does not require additional maintenance other than timely lubrication (if you do not take care of the lubrication in time, it is quite possible to “kill” both the tire and the chain itself).

It is worth noting that the two-stroke engine of this unit is designed in such a way that it runs on a gasoline-oil mixture. It is necessary to add only high-quality oil to gasoline for STIHL chainsaws. You can read about which oil to use for a Stihl chainsaw here.

The quality of these operational elements will largely determine the impact on the operation and service life of the entire system.

Chainsaw Shtil 180 instructions provide for strict adherence to all rules of its operation

This is important for warranty repairs and also for extending the service life of the chainsaw. It is very important to use good chainsaw chain oil.

Repair of STIHL MS 180 chainsaw. No oil supply.

main reasons why not

Stihl
oil arrives .

Chainsaw fuel system: 1 – fuel filter, 4.5 – carburetor, 3 – manual preparatory pump.

If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Otherwise, it will end very quickly.

Slowly reducing fuel during use of the saw is a common process. If it is missing, the chain is not lubricated correctly, so working with the chainsaw will be smooth. It is necessary not only to be able to eliminate breakdowns, but also to identify them without the help of others.

There is an option to change the fuel supply manually. The correct operation of the lubrication complex of accounting programs is determined by the method of applying the tire. If oil splashes appear, it means that all that remains for our client to do is set it up correctly.

Features of disassembling and assembling a Stihl saw

Disassembling the Shtil saw involves several more nuances, one of which is the prohibited fixation of the flywheel from turning using screwdrivers, screws and other improvised means. This may cause its blades to break. Carry out fixation only in the manner indicated in the diagram. We talked about how to disassemble the Stihl 180, but there are also nuances of reassembling the chainsaw:

We install a piston on the connecting rod, to the left of which is the side of the crankshaft where the flywheel will be;
return the piston to the cylinder. Regarding elements such as a retaining ring, bearings or oil seals, we place them on the shaft and place them in the appropriate place in the cylinder;
degrease the crankcase and its seating area, coat it with sealant and secure it with 4 screws.

These are the nuances of reassembling the engine itself, during which difficulties may arise (if you disassembled it), all other parts are assembled in the reverse order step by step. Don't forget to check the installation of the rod on the carb and the connection of the ignition wire. Also, all the nuances can be viewed on video. The KoshiKosa petrol tool store is pleased to offer all its knowledge to each of our readers and customers.

Practical recommendations

Lubrication hole layout.

Before you start using chainsaws, you need to check the lubrication system of the chainsaw chain. For this purpose, it is necessary to hold the end of the tire by placing a sheet of paper under it. When the speed increases, an oily strip should form on the sheet.

Proper lubrication of the chain greatly increases the life of the chainsaw headset. If there is not enough oil, the device will operate dry. The cutting set will quickly break. The friction of the parts should be minimal, so all guides and hinge joints should be covered with an oily film.

When the chain moves along the guide bar, the lubrication system must provide a constant flow of oil. This function is performed by the oil pump. With its help, the required amount of oil is supplied to the guide bar and its groove.

The driving links of the chain spread oil over the total length of the groove. A guarantee of proper chain lubrication is considered to be:

fine tuning of the oil pump;
completely filled oil tank;
correct choice of oil.

Before starting work, it is necessary to constantly monitor the operation of the lubrication system. The correct supply of lubricant is determined by the sides of the chain; they must be lubricated at all times.

Basic parameters of a chainsaw chain.

The need for lubricants is always different. It all depends on what needs to be cut. When the length of the cut reaches large values, the tree has high hardness and thick bark, it is necessary to have a large supply of oil.

If the cutting set smokes or the chain stops, we can talk about a lot of heating. The main reason is lack of lubrication. Other reasons may be:

dullness of the chain;
strong tension.

Oil supply system repair

If there is no oil supply to lubricate the chain, it is necessary to diagnose the entire system and determine the reason why the oil is not supplied. There may be several main reasons:

Clogged oil filter or oil system;
Missing thread on the oil pump worm gear;
Blockage or malfunction of the pump itself;
Depressurization of the oil system (there will be oil leaks on the bottom of the chainsaw).

To check the threads on the worm drive of the oil pump, you will need to remove the chainsaw drive sprocket and unscrew the clutch. To do this, the spark plug is unscrewed and a piston stopper is installed in its place, thereby ensuring reliable fixation of the tool’s crankshaft from turning.

Next, remove the cover from the side of the bar of the Shtil 180 chainsaw, and using a screwdriver, remove the retaining ring holding the drive sprocket, after which the sprocket itself is removed.

The clutch is untwisted using a 19mm socket and a wrench. It is necessary to unscrew the clutch clockwise, since the thread is left-handed. There is a reflective plate behind the clutch, this also needs to be removed. The next part is the worm drive of the oil pump. Having examined and discovered the absence of a plastic thread, you can safely throw out the part and install a new one in its place, since it is impossible to restore it. Assembling the Shtil 180 chainsaw is carried out in the reverse order.

If the gear is in normal condition, disassembling the saw continues; for this, the corkscrews are removed from the shock absorbers, the rear handle is untwisted and the throttle control rod is disconnected, after which the handle block is removed from the shock absorbers using a powerful slotted screwdriver.

It is necessary to remove the handles to provide access to the bottom where the oil pump is installed.

At the next stage, the oil hose coming from the oil tank is removed from its seat on the body and the line is checked for blockages by supplying air through the oil hose into the oil tank body. If a blockage is detected, it must be cleaned; if this is not possible, the faulty hose must be replaced.

Next, the oil pump is removed from the body of the Shtil 180 chainsaw and washed in gasoline.

After repair, we assemble the Stihl 180 chainsaw in the reverse order. An important point is to seal the oil hose at the installation site, into the seat on the housing. It is necessary to rinse the hose and the hole for its installation with gasoline, then blow with compressed air until completely dry and coat it with sealing oil-resistant sealant, and then install it in place.

The most common types of chainsaw malfunctions

The Stihl 100 eighty chainsaw is operated in accordance with the instructions included with the tool. The user turns on the starting system after he is convinced of the presence of oil, gasoline, and is convinced of the correct chain tension.

Work with the equipment begins after it is safely secured in the hands. If a tool malfunction is detected, you need to find out what caused the malfunction of the Stihl chainsaw.

The reasons that caused the tool to malfunction may be:

The occurrence of a leak in the oil system;
Formed breaks in the crankcase cord;
Carburetor malfunctions;
Air entering the crankcase through the seals;
Worn condition of the worm gear in the oil pump;
There is no spark at the ignition cross section;
Worn drive sprocket;
Violation of the integrity of the eye under the control lever.

To carry out independent repairs of a broken Stihl chainsaw, we use the tools that every consumer has in stock.

It can be:

Screwdrivers;
Socket wrenches and wrenches;
Hexagons;
A vacuum gauge used to determine defects in oil seals, carburetor, crankcase;
An air compressor used for purging and cleaning components and assemblies;
T-key STIHL Torx 27;
A stopper that limits the stroke of the crankshaft;
Bearing puller.

What kind of damage may occur?

Chainsaw malfunctions can be divided into groups:

Engine malfunctions (ignition, exhaust and cylinder-piston systems, fuel supply).
Failure of components such as the clutch, chain brake, lubrication system or tire.

Chainsaw engine failure is more common than others. Most of the time is spent on its detection and repair. As a rule, it comes down to such manifestations when the engine runs unstably or stalls altogether, the engine does not start, and does not develop power.

Before you start repairing your chainsaw, first check all the possible causes of problems in its functioning, or better yet, watch the video. Fortunately, today you can find any material of interest on the Internet.

Then you will have to prepare the necessary tools to repair the damage:

device diagram (must be included in the delivery kit);
keys, including spark plugs.

Ignition system malfunction

When the engine refuses to work, but there is a spark at the spark plug and fuel is flowing, you should check the ignition.

Checking it is not at all difficult: unscrew the spark plug, adjust the gap between the contacts, connect it to the wire and press it against the cylinder body. After this, watch for a spark to appear.

If any deviations occur, you need to adjust the ignition system. In general, this process is similar to adjusting the ignition in other two-stroke engines.

Checking the ignition system

Chainsaw ignition system

If the tool does not start, then the problem may be hidden in the trigger mechanism or in the ignition system. In this case, if the starting device is working normally, then you need to carefully examine the spark plug. It must be turned out and carefully examined.

Increased attention here needs to be paid to the electrodes, on which plaque may accumulate. If there is a red-brown coating on the electrodes, this indicates severe defects in the entire starting system. So, the cause of the malfunction may lie in the carburetor.

If the ignition system works normally, but the tool does not work correctly, then the problem may be due to an excess of air-fuel mixture. Here it is necessary to adjust the carburetor and clean the jets.

Do-it-yourself chainsaw carburetor adjustment

If during the inspection, carbon deposits were found on the spark plug, this means that the tool runs on low-quality gasoline. Also, a prerequisite for this may be improper functioning of the carburetor.

To solve this problem, you must perform the following steps:

Remove the carburetor and check it;
Clean and adjust it as necessary;
Change fuel;
Install the carburetor and check the tool in operation.

It should be noted here that the carburetor is a rather complex unit. Therefore, if there is a need for its repair, it is better to seek help from specialists.

And in this article you can find out how to make a hand-held garden auger.

Having this information, you can repair the Stihl 100 eighty chainsaw at home. Naturally, it is necessary to take into account that more severe faults are best addressed in service centers.

See the review about diagnosing the lubrication system of the Stihl MS180 chainsaw:

Do-it-yourself adjustment of the Shtil 180 chainsaw carburetor

Adjusting the Stihl MS 180 carburetor is necessary to ensure efficient operation of the saw when used at maximum speed, and to save fuel. To perform this procedure, you will need to clean the air and standard fuel filters.

The carburetor of the model can be adjusted using three standard screws. Screws L and H are needed to pre-set the air-fuel mixture ratio, which is regulated by different throttle valve positions. Screw S is responsible for fine-tuning the operation of the chainsaw at idle. The procedure for setting up the carburetor is as follows:

First you need to start the tool and begin to alternately turn the screws H and L clockwise until it stops. Both screws will then need to be slowly turned 2 full turns in the opposite direction;
After this, you need to find the maximum engine speed when the saw is idling. To do this, screw L should be turned alternately in different directions. In this case, the screws should not make creaking sounds. Once the base maximum speed has been found, you will need to slowly turn screw L a quarter turn counterclockwise;

Removing and disassembling the engine

The engine is held in place by 4 screws installed on the bottom of the Shtil 180 chainsaw. To remove it, you need to unscrew them, and then carefully remove the engine from the seat and the rubber carburetor pipe.

To disassemble the engine, 4 crankcase screws are unscrewed and it is removed, then you can remove the crankshaft assembly with oil seals, bearings and piston rings.

Removing bearings and seals usually does not require additional tools, but if the bearings were pressed onto the shaft with force, then a special puller will be needed for dismantling.

To remove the piston from the connecting rod, you will need to remove the retaining ring from the seat using a thin screwdriver, then press out the piston pin from the opposite side, after which the piston is removed to the side.

Malfunctions of the chain lubrication system

Each instruction manual indicates the need to monitor the condition of the chain lubrication system.

Typically, system malfunctions occur due to clogged channels through which lubricant is supplied. If there is a slight oil leak, you can continue operation. But if the oil leaks are large enough, then you need to check the tightness of the connections of the tubes to the pump fittings. The leak can be eliminated using sealant or replacing the tubes.

You should also pay attention to the condition of the oil pump. If there are cracks in its body, replacement is necessary.

Order oil pump Shtil 180 and other chainsaw models

We have already said that the Shtil 180 oil pump has a non-separable design, which means that if it breaks, the device should only be replaced as an assembly.

And here there are two purchasing options - purchasing an original oil pump or a third-party one. In the first case, you will not have any problems - you simply purchase a Shtil oil pump for a specific model of gasoline saw.

However, if you decide to purchase a device from a third-party manufacturer, then a natural question will inevitably arise: “Which company is best to choose?” And we will help you with this. Below we provide a summary table showing the most popular models of Stihl chainsaws and the companies that manufacture oil pumps for them:

The 230th model is a fairly powerful entry-level gasoline chain, equipped with a 2-kW engine. With its help, you can prepare firewood, trim trees in the garden, and build a wooden bathhouse. A good non-original oil pump is manufactured for it by Emas (Taiwan);
The 250th model is the most powerful among all entry-level gasoline saws, equipped, depending on the specific modification, with a 2.3 or 3.1 kW engine. Shtil 250 oil pumps are manufactured by a large number of third-party companies, among which we would like to highlight the Serbian company Saber. Unlike many others, she herself produces gasoline saws under her own brand;
The 260th model is one of the “junior” professional-level chainsaws, equipped with a 2 kW engine. For this model, we recommend paying attention to the products of the Taiwanese company Noker;
The 290th model is a powerful chain saw with a 2.8 kW motor, most effective when working in the garden and for small logging operations. Farmertec produces very good spare parts and consumables;
The 361st model is a professional chainsaw with fairly compact dimensions and a powerful 3.4-kilowatt motor. For it, we recommend purchasing an oil pump manufactured by the Turkish company Ital.

In our online store you can purchase an oil pump for chainsaws and other brands. We have organized the sale of this unit at the best prices.

How to properly disassemble a Shtil chainsaw

Before directly disassembling the Stihl saw, a preparatory stage must follow. Prepare a comfortable table, dry rags, brushes for delicate wiping of parts, clean water, gloves and a dry place away from fire

It is also important to understand that there should be no fuel in the unit. It would be optimal to work it out rather than drain it and let the saw cool for several hours before disassembling it.

The procedure is simple and clear:

remove the chain, tire and side cover; using a compressor, if available, brushes, a dry sponge - clean Shtil from oil, dirt, dust, smudges, sawdust

Pay special attention to the drive sprocket - it may contain a lot of soot and dirt; if large accumulations of dirt are difficult to remove mechanically, then pure gasoline can be used; We look for three rubber shock absorbers and remove the handle. This can be done by removing the stubs

Using a strong screwdriver, first squeeze out the upper shock absorber, and then the one located at the rear handle; disassemble the back of the handle by unscrewing two screws. So we disconnect the rod from the gas trigger (it connects the carburetor and the gas trigger, which is in the handle); at the moment of fixing the handle only on the shock absorber - it’s as if we are turning out all the “insides” of the saw and twisting it to the side - we remove it from the last clamp like an elastic band; the starter is removed by dismantling the top housing cover and unscrewing the 4 screws on which it is attached. Next, remove the tank caps - fuel and oil. Under the starter there is often an accumulation of dirt and sawdust, which also needs to be cleaned; a 13mm head will help unscrew the flywheel. We block the crankshaft from turning by unscrewing the spark plug, namely through its hole we fix the piston stopper; if the piston is blocked, you can unscrew the flywheel nut; Before removing the clutch, disconnect the drive sprocket. The lock washer is removed from the grooves, as well as the needle bearing; disassembling the Shtil 180 chainsaw involves removing the clutch with a size 19 head. Next, remove the reflective plate and the oil pump drive; We disconnect the ignition wires and the air damper rod from the part called the engine lever, and remove the lever itself. Next, unscrew the nuts of the carb and air filter using a convenient 8-mm socket with an extension (if one is available); by unscrewing 2 nuts and pulling slightly towards yourself, you will remove the next part, the muffler; There are 4 screws in the bottom of the saw that hold the motor. When carefully removing it, do not forget about the rubber carburetor pipe, which can be touched.

Disassembling the engine of the unit is a separate diagram, but in general, we have looked at how to disassemble a Shtil chainsaw. Regarding other popular models, such as 250, the procedure should be carried out similarly. Like other parts, you can always order a file for sharpening chains at KosiKosa.

Repair of STIHL MS 180 chainsaw. No oil supply.

the main reasons why stihl oil does not

180.

Chainsaw fuel system: 1 – fuel filter, 4.5 – carburetor, 3 – manual preparatory pump.

If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Otherwise, it will end very quickly.

Slow reduction of fuel during operation

sawing is a common process. If it is missing, the chain is not lubricated correctly, so working with the chainsaw will be smooth. It is necessary not only to be able to eliminate breakdowns, but also to identify them without the help of others.

Troubleshooting

If oil is supplied to the chain in excessive quantities, not only while the saw is running, but also at idle, manual adjustment should be made (if the pump design allows this possibility). This is done using a screw, which is located on the body near the guide bar, usually on the bottom or side. Tightening the screw reduces the oil supply, loosening it does the opposite. If the adjustment does not help, it is necessary to check the serviceability of the pump, and also inspect the tire - perhaps a gap has formed at the point where it connects to the body, through which oil flows past the chain.

Lack of oil can be caused by several reasons, each of which has its own solution:

Oil pump malfunction. As a rule, it consists of an unsuitable gasket. In order to replace it, it is necessary to carefully disassemble the pump so as not to damage its moving parts. Next, a new gasket is installed, after which the pump is assembled and installed in place.
Broken oil supply hose. If the pump gasket is in good condition, or if replacing it did not lead to results, you should check the tightness of the hose. If it is faulty, it needs to be replaced. Otherwise, it would be a good idea to clean it and seal it with sealant.

If the reason does not lie in a breakdown of the pump, it is necessary to inspect all conductive holes and channels for blockages, and, if necessary, clean them of foreign objects. This can be done with a jet of compressed air.

Oil does not flow to the chainsaw chain: causes and solutions

When the saw chain of a chainsaw moves in the groove of the bar due to friction, a huge amount of heat is released. If oil does not flow to the chainsaw chain, you need to stop work and take all measures to eliminate the malfunction of the lubrication system. The combination of enormous loads and overheating of the headset is accompanied by its accelerated wear and premature failure.

Without exception, all chainsaws and their electronic analogues are equipped with systems of the same operating principle, the means of which are used to lubricate the bar, saw chain and its drive parts.
The standard composition of this device includes a reservoir from which chain oil is supplied to the pump inlet with a fixed or adjustable capacity.
Next, the working fluid in measured quantities enters the groove of the tire, in which it is moderately distributed by the shanks of the saw chain throughout the entire headset and the working surface of the drive sprocket crown.

Tires of productive sets with a length of four hundred mm or more are equipped with a driven sprocket. Repeated bearing lubrication is done personally, after 6-8 hours of operation.

Repairing the Oil Pump of Chainsaw Shtil 180

The STIHL MS 180 chainsaw is an indispensable tool designed for harvesting wood and other wood construction work. It is one of the most recognized gardening devices that is armed with functional capabilities.

The weight of the tool is about 4 kg. The power reaches 1.5 kW, and the bus length is 35 cm.

How to Remove the StihlRead Trimmer Flex Shaft

Note that this saw model received electric ignition and a fairly fast chain tension from the semi-professional device. Additionally, the STIHL MS 180 saw has 4 tanks designed for gasoline and also for oil consistency.

One of the main features is reduced vibration.

This result is achieved thanks to 4 shock absorbers. It is no secret that high depreciation has a harmful effect on human health, and Europe has been fighting it for a long time.

It must be emphasized that it is not better to disassemble this saw without the help of others without special instructions; in solving this issue, it is better to entrust the device to specialists.

Owners of this tool model must be prepared to face such a nasty situation as a leak of oil to lubricate the chain. Oil can leak out while working with equipment and when simply lying idle.

What is the reason for this phenomenon? There is a possibility that oil leaks due to density problems in the area where the hose from the oil tank and the pump connects.

To be able to solve the STIHL MS 180 problem related to the oil supply, purposefully disassemble the device.

Solution to the problem:

Check the hose; if it is damaged, replace it with another one. Or try to degrease the hose and wash it, and put it on sealant, our client should still earn money.
Check the filter oil for damage, clean it (if you filled in waste oil)
Also, perhaps the reason is a clogged priming, at the same time a vacuum appears in the fuel tank and affects the fuel supply. The problem is that the carburetor is adjusted better, and sometimes the channels are clogged, and in other words, the air filter, you need to carefully clean the filter and carburetor channels.

Oil pump on Stihl CHAINSAW replacement for beginners from A to Z.

The main problem is due to vile oil.

It is not recommended to pour oil into a chainsaw that is not intended!

Spend no expense on original oil. Stihl HP 2-stroke oil is not much more expensive, but cleaning costs even more.
You need to pour high-quality fuel into the fuel, you can use Mobil 1, three-phase is suitable for lubrication, do not pour waste.
Of the cheap options, mineral oil is 15-40, in winter 10-30. Naturally M8, for example, or M10.

Keep your personal safety in mind when operating a chainsaw.

Remember that the performance of the chainsaw is affected by the quality of the oil being poured. Low quality oil causes the tool to operate ineffectively and has a bad effect on its parts.

If you set a goal for the STIHL MS 100 oil pump to deliver oil without difficulty, periodically check and clean the pump. Thus, the oil supply process will be normal.

The STIHL MS-180 carburetor is equipped with one idle function screw. The jet of the working version of the load is not adjustable, in other words, it is impossible to change it.

You need to know the main rules of the idle speed function:

1) check the air filter, if necessary, change it;

4) check the spark-proof grille, if necessary, change or clean it. Later, there is an option to turn on the engine and warm it up at the end.

Repairing a STIHL MS 100 eighty carburetor is a very difficult process. Note that when performing repairs, the risk of sudden changes in the cylinder-piston group is practically absent.

Such signs directly or indirectly indicate problems in the chainsaw chain lubrication system.

The first thing that needs to be done if there is a suspicion that the oil for lubricating the chain is not supplied is to check its supply. There are 2 ways to do this. The first is painstakingly described in the instructions for the tool and consists in the fact that you need to start the chainsaw, very much increase the gas and point it towards any obstacle.

If the lubrication system is working properly, the oil will fly off from the tip of the tire onto the surface, the tire is aimed towards the busy side, and a stripe of oily drops will appear. Even if there are violations in the system, the surface remains unstained.

Chainsaw carburetor malfunctions and repairs

All carburetors are cleaned the same way, the main thing is not to be afraid and not to lose anything. For repairs you will need to prepare:

Recent posts Chainsaw or electric saw - what to choose for the garden? 4 mistakes when growing tomatoes in pots that almost all housewives make Secrets of growing seedlings from the Japanese, who are very sensitive to the soil

any brush;
Phillips screwdriver;
head for 8;
some gasoline.

First of all, using a brush, dirt and dust are cleaned. Then remove the lid and filter. The two air filter nuts are unscrewed and the air collector housing is removed. Now you can see the carburetor and the choke and accelerator rods. By lowering the throttle down with your finger, you will need to remove the accelerator lever.

To move the carburetor from its seat, you must first remove the choke lever and close it completely. Now you need to remove and pull the engine stop wire towards you. It is also necessary to remove the plastic lever on which the wire is attached. On the right it is inserted into the hole, and on the left it can be lifted.

The carburetor is freed and can be pulled out and cleaned. This is best done with a compressor, but if you don’t have one, the parts can be washed in clean gasoline.

Don’t forget about the fuel filter, which also needs to be removed and the fuel hose blown out. Everything is put together in reverse order.

If, after assembling the carburetor, the saw does not start well and smoke comes out of the muffler, then most likely the spring located under the needle lever has been lost. Due to the absence of this spring, the needle does not shut off the fuel supply, so the spark plug is “flooded” with gasoline. Of course, to fix this problem, you should find the spring and put it in place.

When repairing a carburetor, you should remember that it is a rather complex unit, which consists of various small rings and parts

Therefore, it is necessary to clean and repair it with special care and caution.

If the chainsaw does not start or stalls, then in addition to the carburetor itself, you should check the functionality of the spark plug. If it is faulty, it should be unscrewed and dried. Also, excess fuel must be drained from the spark plug through a special hole.

It must be remembered that drying must be done for at least thirty minutes, after which the candle is put in place and the tool is started.

The cause of the malfunction may be poor contact between the end of the spark plug and the high-voltage wire. If you don’t like the work of the candle at all, then it is better to replace it with a new one.

Parts of the Shtil 180 chainsaw, such as anti-vibration elements, chain, tire, and drive sprocket, wear out faster than others. Therefore, to quickly replace them, it is recommended to keep spare parts in the workshop.

Eliminating the causes of chainsaw malfunctions with your own hands will in any case cost less than repairing the tool in a service workshop. In order not to rack your brains over why the tool stopped working, you can watch video instructions for troubleshooting various breakdowns of the Shtil 180 chainsaw. However, in case of serious damage, it is better not to do the repairs yourself and entrust the work to a specialist.

Chainsaw Shtil Replacement Fuel Filter

Chainsaw malfunctions and repairs

A chainsaw is not such a complicated device. But if a malfunction is detected, you need to have at least basic knowledge in order to find and remove the defect that has appeared.

Let's look at the main malfunctions of chainsaws, find out what they are connected with, and also look at the main steps to correct the breakdowns.

The most important thing before starting repairs is to correctly identify the fault. And there may be several reasons for the inoperability of each element. Therefore, before you start disassembling the chainsaw, you need to try to find what is causing the failure.

Typically, failure of chainsaws to operate is caused by a malfunction of the motor or the appearance of breakdowns in its other components.

Motor malfunctions include:

ignition fault;
problems in the fuel supply system;
piston or cylinder malfunction.

In other components, in most cases, malfunctions appear due to failures of the brake mechanism, lubrication system, clutch operation, tires, etc.

Let's look at both groups of defects so that you can, if necessary, find the cause of the breakdown on your own, without going to a repair shop.

Engine malfunctions

In most cases, the following disadvantages are observed in the operation of the motor:

the engine does not start at all;
starts, but immediately stalls;
does not develop suitable power;
works unstable.

To find the cause of the problem, it is necessary to analyze the probable preconditions in order using the method of elimination. Let's go through this chain so that you know how to find a flaw in a chainsaw if it occurs.

Chainsaw ignition system malfunctions

Problems in the ignition system in most cases become a prerequisite for failure of the engine of a gas powered tool. Therefore, you should start looking for defects specifically from it.

Examine the candle. To do this, carefully remove the high-voltage wire from the head, and then unscrew the spark plug from its socket using a special wrench.

If the spark plug is wet, it means there is an excess of fuel. In most cases, the supply of excess fuel is associated with incorrect carburetor adjustment or problems with the ignition system.

The candle should be carefully wiped with a dry cardboard napkin and dried. It is also necessary to drain the cylinder, close the fuel supply and run the starter a couple of times to remove excess fuel mixture.

After these steps, you need to put the spark plug back in place, open the fuel supply and try again.

If there is a noticeable amount of dark carbon on the spark plug, this usually indicates a malfunction in the fuel supply - a violation of the gasoline/oil ratio, bad oil, or the need to adjust the carburetor.

In this case, the spark plug must be cleaned with a needle or a sharp awl from accumulated carbon deposits, the electrodes must be cleaned with sandpaper until an iron sheen appears, and screwed back into place. In this case, it is necessary to focus on the tightness of the spark plug gasket.

the chainsaw still does not start, you need to check for a spark in the spark plug. With the cap of the high-voltage wire installed, lean the spark plug skirt against the cylinder and pull the starter, as shown in the photo below:

If a blue spark jumps from a distance of 2-3 mm, then everything is in order. If a spark occurs only at a distance of 0.5 - 1 mm, most likely there are problems with the ignition system. If there is no spark, you need to check the high-voltage cable with a probe. Maybe there was a wire break in it.

If all the above steps do not lead to success, try replacing the spark plug with a previously working one and try starting the chainsaw again.

Also, the lack of a spark may be due to a violation of the gap between the ignition module and the flywheel magnetic circuit. The gap should be 0.2 mm. The required gap can be set using a 0.2 mm spacer, which is placed between the flywheel and the ignition module.

Malfunction of the fuel supply system in the chainsaw

If everything is in order with the ignition system, then we go further and check the fuel supply system of the chainsaw.

Failure of the fuel supply system is usually associated with one of the following circumstances:

fuel contamination ;
the hole in the tank lid is clogged;
shortage of the amount of incoming fuel mixture.

We disconnect the fuel hose from the carburetor and see whether fuel flows out of it or not. If the fuel flows in a free stream, then everything is in order. The lid and filter work properly. If the fuel mixture does not flow at all or flows very weakly, then clean the hole in the cover (breather) with a needle.

We remove the fuel filter through the filler hole using a hook (can be bent from a wire), together with the absorption hose. You must first empty the fuel tank. We disconnect the filter and clean it or replace it with a new one.

It is recommended to update the fuel filter every 3 months. As for the missing amount of fuel consistency flowing from the carburetor into the cylinder, the reason may lie in a violation of the ratio of fuel and air mixed in the carburetor. Main prerequisites: clogged air filter, clogged carburetor channels or filter .

Of course, when repairing chainsaws, it is necessary to clean the air filter, since it gets dirty quite quickly. This reduces the amount of air entering the carburetor. In this case, the fuel mixture at the outlet turns out to be excessively enriched.

A dirty filter must be removed very carefully so that the accumulated dirt does not fall off and get into the carburetor. The filter must be cleaned or washed in water and detergent. Then we dry it and put it back.

Carburetor malfunction

If all the actions described above did not lead to success, perhaps the reason for the chainsaw’s inoperability lies in a malfunction of the carburetor.

In this case, it is checked and adjusted. However, if you do not have experience in performing such work, then you should find through friends or through an advertisement a specialist who knows how to do this. Otherwise, you risk being left without a saw. A carburetor is a device consisting of many very small parts, which, if disassembled improperly, can simply fall out and get lost.

A video on how to repair the carburetor of a Stihl MS 250 chainsaw is presented below (click triangle to play):

Chainsaw muffler malfunction

It often happens that during prolonged operation, the walls of the exhaust pipe become covered with soot, which prevents the free exit of exhaust gases.

In this case, you should remove the muffler (if possible) and wash it with detergent, then dry it thoroughly with a hairdryer.

ATTENTION! Carbon deposits contain carcinogens. During dry brushing, it can enter your lungs, which poses a threat to your health.

Pump structure, lubrication system and principle of operation

The oil pump drive consists of two parts: a plastic gear with a worm gear and a wire lever that transmits force from the drum sprocket to the worm gear.

One of the main defects of the saw’s oil system is a defective thread on the plastic gear of the oil drive, therefore, no matter how hard it is, you need to keep its wear and the quality of the thread under control.

The lever is aggressively mounted to the gear and they are supplied as one piece. The tip of the wire arm has a corresponding bend, which is designed for the best grip on the sprocket drive drum.

On the pump body there is a receiving hole for oil and a groove-channel through which oil from the oil wire gets directly into the pump. The mechanism is installed in the body of the Stihl 180 chainsaw.

All about the Stihl 180 oil pump

The Stihl MC 100 eighty chainsaw uses a mechanical oil pump as an oil supply mechanism for chain lubrication. What's cool is that the Stihl 100 oil pump is made from eighty hundred percent iron parts and is practical and extremely reliable. Let's take a closer look at how the oil supply system of the Stihl 180 chainsaw is organized.

Replacing the Stihl MS180 oil pump drive (worm gear)

The oil pump of the Stihl 100 chainsaw is a reliable and unpretentious part, which from time to time is a prerequisite for the lack of supply of chain lubrication. It is necessary to disassemble and replace the pump only in the last case, when you can be sure that the cause is 100% there. This can be done naturally at home, since this is a fairly ordinary operation.

Lubrication system malfunctions and how to fix them

The main malfunctions of the oil supply system on a chainsaw can be divided into two main types: these are general malfunctions inherent in all chainsaws and individual ones, which may vary depending on the type of pump and worm gear installed on a particular model. Let's begin to understand the faults in order.

Signs of a malfunction of the lubrication system, checking its performance

The chainsaw chain is dry and has a pale tint without shine.
The chain stretches relatively quickly.
The tire is very hot and may even partially melt the paint.
The oil from the tank is practically not reduced.
Reduced cutting efficiency on a sharp chain

All these signs indicate that the lubrication process is not proceeding properly. In order to check the oil supply to the lubrication system, you need to remove the side tire of the chainsaw and start it. Next, you need to slightly increase the speed while observing the end of the oil line. If oil comes in, most likely the amount is not enough for normal lubrication and you need to clean or replace the filter and, if possible, adjust the flow. If it does not, the problem is more serious and requires further diagnosis.

There is a way to check the oil supply without removing the tires. To do this, you need to point the end of the bar towards, for example, a freshly cut piece of wood from the side of the cut and increase the speed as much as possible, while trying to keep the end of the bar at a distance of no more than 10 cm from the block. If oil spots begin to appear on its surface, it means the oil is being supplied.

Troubleshooting

Once it has been determined that oil is not being supplied, further diagnosis is only possible if the oil system is completely removed. Of course, in some situations replacing the filter helps, but this is very rare.

Most common faults

Broken oil hose. It can sometimes be detected by visual inspection. The problem is solved by replacing the faulty part.
There is no thread on the oil pump shaft; replacing it will help.
A defective thread on the pump drive gear can be similarly solved by installing a new part.
Lack of main shaft corkscrew (relevant for some instrument models, for example, Homelite). You can fix it by installing a nail of a suitable diameter instead of the original corkscrew, cutting it to the required length.
Blockage in the line. Can be removed by blowing with compressed air or mechanically, using a wire of a suitable diameter.
Filter element clogged.
The Stihl MS 180 tool, whose pump is not dismountable, often gets clogged. You can try to wash it in clean gasoline, if that doesn’t help, replace it.
In Chinese chainsaws (Gypsy), it very often cuts off the grooves on the main gear, through which the force from the sprocket is transmitted to it.

Individual malfunction of the Stihl MS 180 lubrication system

Due to the fact that the Stihl MS 180 is one of the most common models of chainsaws, I would like to dwell in more detail on one fault inherent only to it and describe a method for eliminating it without replacing parts.

Quite often, on the Shtil MS 180 chainsaw, depressurization of the oil line is observed in the place where the oil line coming from the tank is installed in the saw body. The malfunction can be determined by the characteristic lubricant leaks on the bottom of the tool.

To eliminate the problem, you need to remove the chainsaw handle, remove the hose from the mounting hole, clean and degrease. After all these manipulations, apply sealant to the hose seat and install it into the chainsaw body.

You can learn more about troubleshooting and complete diagnostics of the lubrication system of the Stihl chainsaw by watching a video that shows the step-by-step process of disassembling and repairing the lubrication system.

Malfunctions of the pump and the system as a whole

As you know, nothing lasts forever in this world and everything has to be repaired over time. The oil system of the Shtil ms 180 is no exception, and has its own specific malfunctions. Let's take a closer look at them.

Signs of a malfunctioning lubrication system are as follows:

the chainsaw chain is absolutely dry and does not shine;
oil does not leave the oil tank;
the chain stretches quickly and this happens constantly;
the saw bar moves to the side when sawing;
The tire also heats up in the area of the drive sprocket and the paint melts.

All these signs directly or indirectly indicate problems in the chainsaw chain lubrication system.

The first thing to do after you suspect that chain lubricating oil is not being supplied is to check its supply. There are two ways to do this. The first is described in detail in the instructions for the tool and consists in the fact that you need to start the chainsaw, increase the gas as much as possible and point it towards any obstacle.

If the lubrication system is working properly, the oil will fly off from the tip of the tire and a strip of oily drops will appear on the surface towards which the tire is pointed. If there are still violations in the system, the surface will remain clean.

The second way is to remove the tire from the chainsaw and start it. When the engine speed increases, oil will flow from the oil channel at the tire shank installation site; if this does not happen, it is necessary to look for the cause of the malfunction.

Diagnostics

Diagnostics should begin with inspecting and checking the oil receiver (filter) of the Stihl 180 saw. As a rule, if the filter is very dirty, the oil supply may stop.

To save money, you can try to clean a clogged filter by thoroughly rinsing it in gasoline.

Next, you need to remove the drum sprocket and check the condition of the drive gear. The thread on it must be clearly defined, not licked or have any other defects; also, when the gear is removed, it is necessary to check the wire lever. It must press the gear tightly and not turn, otherwise the gear stands still and does not transmit force to the pump, as a result of which the oil supply stops.

If all of the above methods to detect and eliminate faults do not produce results, it is necessary to use extreme measures, i.e. dismantle the pump.

How to remove the pump

The oil pump is installed on the right side of the bottom of the housing, in the same place an oil line coming from the chainsaw tank is connected to it. To remove the pump, you will first need to release the saw from the handle; to do this, unscrew the rear handle of the unit and disconnect the throttle control rod. At the next stage, you need to remove the handle shock absorber plugs and, using a powerful slotted screwdriver, squeeze them out of their seats on the handle.

After the handle is removed, the chainsaw body is turned upside down. The hose leading from the oil tank to the pump will be immediately visible. It must be removed from its seat.

The pump itself is removed using an M5 threaded screw and a wide washer. The length of the screw should be approximately 45-50 mm. A washer is put on the screw and it is screwed into the pump (the inside of the pump has threads). Next, as the screw is screwed in, the washer stop will force the oil pump to rise along the threads. Thus, the pump is removed from its seat. Before starting work, we recommend reading the article on how to disassemble Shtil 180.

To better understand the process of removing the pump, you can watch the video below. In the video, the service center master shows in detail how to remove the oil pump from a chainsaw, and also describes the main malfunctions of the supply system.

The Shtil 180 oil pump is a very high-quality and reliable part, so it is necessary to change it only as a last resort, when all other elements of the system have already been checked.

After the pump is removed, it must be cleaned and purged. As a rule, the main failure of the oil pump is its blockage. Having eliminated it, you can install the pump in place.

Replacing the pump is only required if it is not possible to remove the blockage.

The reason for oil leaks on the bottom of the chainsaw

The Shtil 180 chainsaw has a characteristic malfunction, which consists in insufficient sealing of the installation site of the oil hose in the chainsaw body and the appearance of a leak at this point. To eliminate it, just remove the handle of the Stihl MS 180 saw, disconnect the hose itself, wash and degrease the seat in the body and the hose shank, then apply sealant and install the hose in place. This simple operation will reliably eliminate the malfunction and the oil will stop leaking.

With these connections, chain links and joints can be reliably protected from wear, while ensuring economical oil consumption. High-quality organic oils of this brand provide excellent lubricating and adhesive properties, so their use is not only simple, but also environmentally safe.

Replacing the sprocket

The most common cause of a malfunction in this element is jamming of the chain due to its misalignment or significant wear of the chainsaw sprocket itself.

If any signs of these deviations appear, it is necessary to carefully inspect the plane and teeth of the drive transmission element, paying attention to the depth of drift (it should not exceed 0.5 mm)

If severe wear or traces of deformation are detected on the sprocket body, it can sometimes be repaired, but if the malfunction is serious, a complete replacement is required. Regardless of the nature of the damage found, before repairs you will first need to remove the sprocket from the chainsaw, that is, completely free it from all retaining fasteners.

Most chainsaws have a similar clutch layout. For disassembly, you should use a spark plug wrench, which usually comes with the chainsaw, a clutch remover and a piston stopper.

First, unscrew and remove the tire and remove the chain. Remove the top cover to gain access to the spark plug, unscrew it and install the piston stopper. Often a rope or cord is used as a stopper, but experts do not advise doing this. It is better to use a special stopper when removing the clutch. Remove the side cover, unscrew the clutch (clockwise!) and get to the sprocket.

In another option, the starter is unscrewed and the protection is removed in order to hold the unit that is spinning on the reverse side. The procedure for completely dismantling the main parts of the chainsaw is well presented in the video

All removed parts must be put in one place so that they do not get lost. You can take photos of the chainsaw components so that later after repair you can quickly assemble the tool in the reverse order.
