How to start a chainsaw correctly: instructions

Let's look at the main steps that need to be followed in order to properly start the Stihl chainsaw.

Before starting, the chain brake must be activated. It is activated by pressing it forward (as shown in the photo).
Remove the protective cover from the tire.
If the model has a decompression valve, it should be set to the on position, which will make it easier to start the tool’s motor.

Press the fuel pump to reduce the number of pumps and make starting easier.
The combination lever must be turned on in cold start mode. To do this, you need to lock the gas lever and press the combination lever all the way down.
Before starting the system, it is necessary to ensure a level surface. In this case, the cutting part must be at a distance from the ground, otherwise it will become dull when starting.
Hold the tool with both hands and keep it on the ground. The left hand should be on the chainsaw handle, and the right hand should be on the starting cable. Secure the tool with your right foot by stepping on the rear handle.

Gently pull the starter rope with your right hand until you feel strong resistance. Using force, pull the starting rope several times, starting the engine briefly. In this case, to avoid abrasion, it is recommended to pull the cable upwards from the body.
After a short start, the engine stalls. Now move the combination lever up one click. The lever should take the half-throttle position.

Pull the starter cord again to start the chainsaw engine.
When the engine is started by briefly pressing your finger, operate the throttle lever. The combination lever will automatically return to idle speed.
Without touching the gas lever, move the chainsaw.
Pull the handle towards you to release the chain brake. The position of the left hand remains unchanged, the hand is on the handle. The chain will be unlocked after the appropriate click.

You can see a detailed description on how to start a chainsaw correctly in the video. Using these detailed instructions, you can gain skills on how to start a chainsaw.

What to do if the chainsaw does not start?

But what to do if all the steps specified in the operating instructions have been followed, but the chainsaw still does not start? Regardless of the manufacturer of the chainsaw - Shtil, Husqvarna, Partner, Ural, Druzhba - a number of general activities can be identified for the tool factory.

Below are practical tips from professionals that have been tested in practice and have proven effectiveness:

Don't be nervous and don't try to adjust the chainsaw's carburetor.
Set the instrument aside and let it rest. The reason may simply be that the candles are flooded. Give them a chance to dry.
Take the instruction manual. Try starting the saw again. There is no need to turn on the saw brake.
If this does not help, try removing the cover from the chainsaw body and removing the air filter. This way you can check the cleanliness of the filter and at the same time make the starting process easier.
Replace the spark plugs. If it is not possible to install new spark plugs, you can use the old ones by first removing and calcining them.
If a strange, pungent odor appears, it means that excess fuel has entered the chainsaw engine. To correct this situation, you need to remove the spark plug and, turning the saw over with the hole down, drain the excess. Without returning the saw to its normal position, sharply pull the starter several times. This way you will ensure that combustion products leave the chamber. The spark plug must be wiped dry and calcined, and then screwed in again and started without installing the filter.
It is necessary to check the surface of the piston for the presence of fuel. If you unscrew the spark plug and notice through the hole that it is dry inside, you need to inject some fuel into the chamber using a syringe. The cause of problems in this case may be a blockage that interferes with the supply of fuel to the engine. If the engine can be started with a small amount of fuel, then the thrust will clear the blockage and the problem will be solved.
The last two actions can be performed only if the candle is dry.
Check the starter for serviceability. It is impossible to start a chainsaw without a starter.
Check the ignition unit for spark.
Try carefully removing the tool's muffler and starting it without it.

Each saw has its own manufacturing characteristics. You can watch the video on how to start a Husqvarna chainsaw. Follow the instructions carefully and the saw will serve you for a long time.

Modification P371XT Chrome

The popularity of the regular version of the Partner 371 chainsaw provoked the appearance on the market of its improved modification Partner P371XT Chrome. It features higher quality components. Increased engine power, from 1400 (1.9 hp) to 1650 (2.2 hp) W. In the basic configuration, Chrome is equipped with a 40 cm tire.

Features of application

The Partner chainsaw provides a thin, high-quality sawing cut.
Structurally, it is possible to quickly install the tire and tension the chain without the use of special equipment.
Thanks to the optimal balancing of the design and comfortable grips, the chain saw is extremely ergonomic in operation, which ensures stable performance of the operator.
It is not for nothing that the Partner P360S chainsaw is called the latest generation household model - thanks to its high performance characteristics, the tool is suitable for collecting firewood, constructing wooden structures, carrying out sanitary and preventive work in the garden and park.
Despite the budget price of the Partner chainsaw, its design uses technological solutions typical for more productive models of the semi-professional category.
Cooling of the chain during operation is carried out automatically under pressure.

Bar and chain

The sawing mechanism of the Partner 371 chainsaw is made of high-quality materials, using modern technologies and includes everything necessary for safe and efficient operation:

tire and chain;
automatic chain brake;
automatic chain lubrication system;
tension mechanism;

Bar and chain characteristics:

tire length - 35 cm;
chain pitch - 3/8 inch;
number of chain links - 52 pcs.;
chain thickness - 1.3 mm;

When choosing spare tires or chains for the Partner 371 chainsaw, you need to take their parameters into account. When replacing one of the components of the saw set, if the replaced part does not fit, a breakdown may occur. For example, if you install an unsuitable new tire, the result may be that the old chain breaks. If the chainsaw is powerful, then the damage to the headset will be significant; if it is weak, you can get away with just a jammed chain. Therefore, when choosing a chain, always pay attention to parameters such as the number of links.

The Partner 371 chainsaw with a standard bar is designed for a chain with 56 links.

Chainsaw “Partner” 352

A high-power gasoline tool, the design features of which are designed for heavy and prolonged loads.

Advantages:

confident motor resource, supported by sufficiently powerful cylinder-piston engines;
preliminary air purification using CCS technology;
proven anti-vibration equipment, the basis of which is steel springs;
fuel priming pump for simplified starting;
double principle of chain brake activation;
comfortable handles;
cutting set of exceptionally high quality;
modernized design of the gasoline tank.

In addition, this is one of those options that impress with its practicality not only in work, but also in care. Any of the user manipulations, including carburetor adjustment, do not require special knowledge and a lot of free time.

Equipment

The equipment of the Partner 371 chainsaw does not differ from its competitors and includes a standard set.

chainsaw;
tire and chain;
1 year warranty;
tire cover;
combination key;
refill container;
user manual.

Sometimes the completeness differs from that declared by the manufacturer, because... some stores run promotions and can supplement it, for example, with a file for sharpening a chain.

The configuration of the Partner 371 chainsaw cannot be less than that declared by the manufacturer; when purchasing, always check the compliance according to the instructions!

Note! The websites of many stores indicate either the manufacturer - Sweden, or the homeland of the brand - the USA. They don't do assembly. The country of assembly is China, although Partner was originally a Swedish company, a subsidiary of Husqvarna.

Keyless tension system

It began to be used relatively recently, it is considered new, if not advanced. It differs from the classic nut in the following:

another tensioner mechanism;
lack of external tightening nut;
adjustment without additional tools.

Instead of a 13mm spanner nut, the lid has a wing nut (rotary cap) with a handle for hand tightening. It also has a nut, but it is hidden inside. Instead of an adjusting screw for a screwdriver, tensioning in this system is done using a tension wheel (adjustment handle).

Instead of a gear shaft there is a sprocket and a tension washer.

This system also has disadvantages:

the mechanism itself is more complex than a traditional nut;
installation of a cutting set causes additional problems, because makes it difficult to pair all the parts in the right order;
the adjustment stroke is shorter, a slightly stretched chain will still serve with the traditional tensioning system, here it will sag and become unusable.

Advantages and disadvantages

When considering the advantages and disadvantages of the Partner 371 chainsaw, you need to decide which of them are the most critical. Many positive aspects can be common to all chainsaws, while the negative ones are not so important. Therefore, when choosing, you need to rely not on the ratio of “+” to “-”, but on your own needs.

Pros:

chromium-nickel alloy on the cylinder-piston system prevents the appearance of corrosion and rust, extends the service life;
easy start button - decompression valve;
emergency stop of the chain;
there is a vibration damping system;
the crankcase is made of magnesium alloy, due to which its strength is increased;
adjustable oil pump;
Partner branded air purification systems were installed;
EcoBoost system - reduces emissions and fuel consumption; increases torque;
SoftStart system - allows you to start Partner 371 at low temperatures;
a conveniently designed handle that provides a secure grip and contains the main controls;
Auto-choke system - controls the engine throttle;
convenient balance;
primer for pumping fuel;
The CCS system increases the service life of the air filter.

Minuses:

low quality of spare parts and assembly;
positioning the company as Swedish and many stores keeping silent about the fact that the chainsaw was made in China;
startup can be quite labor-intensive due to the poor quality of the chainsaw components;
strong leakage of oil for chain lubrication, positioned by service centers as a normal phenomenon;
the inability of the saw to cut relatively thick branches and trunks;
labor-intensive cleaning of the chainsaw from contaminants that accumulate during sawing;
the most frequently mentioned disadvantages include the low quality of the saw set;
lack of visual monitoring of fuel and oil levels in internal tanks.

Many who bought Partner 371 complain about the high oil consumption for the chain lubrication system. In fact, this statement is not entirely relevant, since oil consumption depends on the settings set by the owner and on the quality characteristics of the product.

Problems with the sprocket and chain are not an objective indicator of the quality of the saw. These are consumables.

You can clearly see how Partner 371 copes with logs of various thicknesses in the video, in which you can see that the chainsaw cuts thin logs quite easily, while thicker logs require some effort.

Device

The general arrangement is made in a traditional style. It is distinguished by its simplicity, which means high reliability of the unit.

Partner 350 chainsaw device

The diagram of the general structure of the Partner 350 chainsaw clearly confirms this.

Starting the engine is simple and reliable. This was made possible thanks to the presence of electronic ignition. The primer (fuel booster pump) plays a major role during startup.

The air filter is equipped with a double air purification system. As a result of equipping the starter drum with an impeller, large debris particles do not reach the filter at all. Thanks to this, its service life increases, and the degree of air purification increases. In general, this has a beneficial effect on engine performance.

Safe handling of a running saw is achieved by the presence of a chain brake operating in two modes - manual and automatic.

The oil pump only turns on while sawing. This means that the chain lubrication system operates automatically. It must be borne in mind that different types of oils are used to lubricate the chain and prepare the working mixture. Video will help you find out what oil is used for the Partner 350 chainsaw

Saw chains. The Partner 350 saw is equipped with an Oregon 91P052E 3/8″ 1.3 mm 52-link chain. Replacement with analogues is acceptable: Stihl 39970000052с and others. For example, Husqvarna 5776151-22

Pay attention to the fact that with a chain pitch of 3/8″ and a groove width of 1.3 mm, the number of links does not exceed 52. Less (46 – 50) is possible, more is not advisable. The anti-vibration system on the Partner 350 works a little harshly

Considering that this saw is not intended for professional use, the system as a whole can be considered satisfactory. By the way, significant improvements have been made in this regard on subsequent models.

Comparison with competitors

If the Partner 371 chainsaw is intended as a tool for your own plot, where from time to time you need to cut down thin branches, bushes, prepare firewood or saw something, then it may well be considered a good option.

If the work is expected to be regular, or the trees to be cut down are massive, then it is better to purchase a chainsaw adapted for this. For example, the Chinese 180th Shtil costs about 2000-3000 more, but there is no doubt about its quality. The fairly budget Husqvarna 140 or 236 also have good performance, although they are somewhat more expensive.

The Partner's classmates include such chainsaws as: Champion, Patriot, Bison, Carver. All of these saws fall into the low-cost tool segment. Partner and Carver can easily be called the best among them.

Note! Among Chinese chainsaws, this specimen is one of the best, but you should treat it with care, give the tool a rest, and do not extract performance from it that is higher than stated.

Chainsaws Partner – troubleshooting and troubleshooting

Like other household equipment equipped with an engine, Partner brand chainsaws require repairs from time to time. This may be due to improper operation of the saw, or to simple wear and tear of spare parts. Be that as it may, the chainsaw needs to be repaired, and it is quite possible to do it yourself.

How to refuel a Partner chainsaw?

As the instructions indicate, to refuel the Partner chainsaw you should use gasoline of at least AI-92 grade. It must be mixed with oil designed for 2-stroke engines.

The optimal ratio of gasoline and oil for a Partner chainsaw is 50:1, that is, 20 ml of engine oil should be diluted in 1 liter of gasoline.

How to set the ignition on a Partner chainsaw?

If you cannot understand why the Partner chainsaw does not start, then first check the ignition system of your tool. Checking and adjusting the gap looks like this:

First of all, remove the cover to which the starter is attached. To do this, we recommend using a T27 hex bit, tools included with the chainsaw, and additional attachments;
Carefully inspect the ignition coil, flywheel with magnets and, especially, the gap between these parts. To do this, use a specially designed gasket;
Installing the ignition on the Partner chainsaw is done by turning the screws, which brings the coil and flywheel closer to each other.

After completing the above steps, install the starter in place, and start the Partner chainsaw. If the saw starts up, you can screw in the screws securing the cover all the way and continue working.

How to remove the clutch on a Partner chainsaw?

Repairing the tool clutch is often required in cases where the Partner chainsaw starts and stalls when you press the gas. However, not all novice gardeners know how to remove the drive sprocket from a Partner chainsaw. You can do this in this order:

First turn the lever and remove the saw chain brake cover;
Unscrew the nuts securing the clutch system using the wrench from the Partner chainsaw kit;
Remove the clutch from the chainsaw and completely disassemble it. If necessary, replace worn parts and clean the walls of the standard clutch elements.

At first, you will need to pull the starter rope several times before the saw starts. This is required to ensure that the installed spare parts finally fit into their intended places.

How to replace the oil pump on a Partner chainsaw?

If you find that the chain on your Partner chainsaw does not spin, then the cause of this problem most likely lies in the wear or breakdown of a separate pump designed to pump lubricant to the chain. The design of the oil pump includes 2 elements - a storage chamber and a working part. Repairing the pump involves disassembling the mechanism, but it is not recommended to take any actions with its working part. The next steps are as follows:

Carefully inspect the inlet and outlet tubes through which the lubricant passes - as a rule, all pump malfunctions are associated with them;
If the channels are clogged, then all debris must be removed. simultaneously blowing them with compressed air;
If cracks appear on the channels, they need to be replaced;

If, after assembling the Partner chainsaw, the lubricant again does not pass to the saw chain, then the pump will need to be completely replaced.

How to adjust the carburetor on a Partner chainsaw?

Setting up the carburetor of Partner brand chainsaws is slightly different from the procedure with chainsaws of other brands. The difference lies in the markings and meaning of the adjustment screws. For adjustment, the manufacturer equipped the Partner chainsaw with three screws - the left fuel quantity screw, the right fuel quality screw and the “T” idle speed adjustment screw. All these screws are located on the left under the top cover of the chainsaw body. Adjusting the Partner chainsaw carburetor is as follows:

Remove the cover and clean the parts underneath;
Unscrew both screws fully clockwise and then turn them 1/5 turn in the opposite direction;
Start slowly turning the quantity screw until you hear the motor start to run at its highest possible speed. Immediately after this, turn this screw ¼ turn in the other direction. As a result, the Partner chainsaw should hold idle speed steadily;
Next, use the quality screw to set the maximum speed for the Partner chainsaw.

If it works like a 4-stroke engine, then the chainsaw carburetor has been configured correctly.

Carburetor adjustment

Before adjusting the carburetor, the chainsaw should be warmed up for a minute. The tool must be in full working order, because any deviation may prevent proper operation and adjustment.

The carburetor is adjusted as follows. There are 3 adjusting screws on the saw carburetor:

T – idle speed adjustment;
L – low speed adjustment;
H – high speed adjustment;

First of all, all three screws are screwed in completely. Immediately after tightening, “L” is unscrewed by 2 turns, “H” by 1.5. These are average values; they can be adjusted in the future. After unscrewing the screws, the carburetor is installed in place and the saw starts.

With the chainsaw running, the “T” screw is gradually unscrewed. You need to release until the chain stops moving. That is, you should get a static chain on a working saw. If you feel that there is not enough traction and the tool may stall, you can add 0.25 turns to the screws.

This completes the carburetor adjustment.

Note! Since adjustment requires turning the screws, it is worth deciding that one turn = 360°

The setup process within the article is described very briefly; if something is not clear to you, we recommend reading the manual for adjusting the carburetor on a Partner 350 chainsaw. The carburetors for the 350 and 371 models are the same, so the setup procedure will be identical. The article covers all the necessary aspects:

device and principle of operation;
necessary tool;
reasons and process of adjustment;
Do-it-yourself repair issues.

Reviews

For an objective assessment, we post several detailed reviews left by real owners through the comment form on our website.

The Partner 371 chainsaw was purchased for household work, mainly cutting for the firebox. We had to saw trunks over 40 cm thick, but the impressions were mixed. Half an hour later the carburetor overheated and the chain tension regulator melted. The chain began to slip off after 20 seconds of operation. Otherwise there were no problems.

Dmitriy

The petrol consumption of the Partner 371 chainsaw is low, and, contrary to expectations, the oil does not leak. There were problems with anti-vibration springs that could not withstand vibration. I replaced it, there were no problems, spare parts are freely available and the price is reasonable. After prolonged work, it does not catch on the first try; the saw periodically needs to rest. In general, it’s not bad for a household tool, if you don’t use it for wear, I recommend it.

Why is the tabular version of presenting information the best?

The chainsaw chain selection table is the most convenient way to visualize summary data. With this indicator, there will no longer be a need to puzzle over whether the dimensions of the new components correspond to the elements that were installed on the factory model. The key characteristics were used:

The first parameter is determined by many factors and is usually within the range of 30-45 cm, although there are exceptions.

Chain pitch is the distance measured between 3 nearby rivets.

The thickness of the drive links or the height of the tire groove can be measured with a regular caliper. Usually it is in the range of 1.1-2.0 mm.

The total number of cutting links is also taken into account when selecting a chain.

What breaks most often

Most often, the chain of Partner chainsaws fails due to overheating, although it is difficult to blame the manufacturer for this: it is necessary to monitor the operating mode of the saw - the supply of lubrication, cleaning the oil channels from dirt, etc. Another minor nuisance is a broken starter cord. The cord is replaced on the spot, on your own, there is nothing complicated in the operation, there is no need to contact the service center.

Over time, the performance of the Partner chainsaw decreases due to wear and tear on carburetor parts. They will need to be replaced, and the carburetor itself will need to be adjusted. Correctly adjusting the carburetor using special adjusting screws will help solve the problem.
