Adjusting the carburetor of a Taiga chainsaw

Chainsaw 245 instructions

The operating instructions are as follows:
- You need to start with the chain and tires. After some time, the tire will need to be turned so that the top becomes the bottom and vice versa.

The chain is placed only in such a way that its cutting movement goes from top to bottom.

Then you need to install the casing. — Then you need to tighten the chain with a wrench strictly clockwise. The chain should not be very tight, but it should not sag either. After this, the nuts are tightened on the casing.

— Chainsaws are equipped with a brake handle. In this case, the brake must be turned off, that is, the handle must be directed towards you.

— Approximately once an hour of working with a chainsaw, it is necessary to adjust the cutting teeth using a template. To do this you need to make about 3 movements from yourself.

— After you have finished working with the chainsaw, you will need to clean the air filter. To do this, wash it with soap and water and dry well.

— After some time (which will be written in the instructions), you will need to lubricate the chainsaw bearings with some kind of grease.

— If more than 5 liters of fuel have been processed on a chainsaw, then it is better to take the chainsaw to a service center in order to adjust the high speed of the tool.

Chainsaw Taiga 245 spare parts - consists of the following spare parts - piston group, carburetor, ignition, engine, brake handle, fuel tank, cylinder, starter, crankshaft, piston, spark plug, chainsaw chain.

DIY repair

The Taiga 245 chainsaw does not last forever and tends to break, like any other equipment. The design of the saw is simple and allows you to repair it with your own hands, almost on your knees, using a handy tool. Let's look at the main breakdowns.

Taiga 245 manual is the main chainsaw document that you should rely on during repairs. We strongly recommend that you study not only the description, but also the content.

Engine

Dvitagel is one of the weak points of the Taiga 245 chainsaw. Common problems:

the engine does not start;
the engine starts, but runs unstable and/or stalls;
works unsteadily;
does not develop full power.

Most of the listed malfunctions occur in the saw due to problems in the ignition system. As everyone knows, the main element of the ignition system is the spark plug, therefore, the first step is to carry out a visual inspection of it.

If you can see excess fuel mixture on the spark plugs, it means it has been “flooded”; you should wipe the spark plug, dry it, put it back and try to start again.

Assess the color of the carbon deposits on the spark plugs. If it is sand-colored, then the spark plug is working. For any other color: black, yellow, red, gray, it should be replaced.

If the chainsaw spark plug is dry, then there is a problem with the fuel supply to the combustion chamber; you should check the fuel supply system.

Fuel supply system

If a malfunction is detected in the fuel supply system (dry spark plug), the first thing you should check is:

Check the fuel filter.
Check the flow of fuel into the combustion chamber.

Dirty filter - replace. The recommended replacement interval is once every 3 months.

To check whether fuel is flowing or not, you need to remove the hose from the carburetor and see if the fuel flows or not. If fuel comes out of the hose, then the problem lies in the carburetor. If fuel does not flow, clean the hose.

Cylinder - piston group

Problems with the CPG are classified as serious and entail high repair costs. The main causes of CPG problems are a drop in power. You can identify problems with the piston by measuring the pressure with a compression gauge in the combustion chamber. To do this, remove the spark plug, insert the device in its place and try to start the saw and look at the device readings. If the instrument needle is in the red zone (8-9 atmospheres), then piston repair is 100% necessary.

Chain brake

The chainsaw chain is stopped by a special brake band; when it becomes clogged with dirt from sawdust and oil, problems with the brake appear. The housing should be removed and thoroughly cleaned of dirt.

Muffler

Over time, the muffler becomes clogged with combustion products from the spark arrester, which causes difficulty in removing exhaust gases. By creating excessive resistance in the exhaust tract, the chainsaw stops developing maximum speed. Also, the muffler becomes clogged due to excess oil in the fuel mixture.

To repair it yourself, you will need to dismantle the muffler, disassemble it and clean it thoroughly. You may have to resort to using detergents.

What carburetors are used on Chinese chainsaws

The most optimal carburetor designs for chainsaws were developed by the world's leading manufacturers - German Stihl, Japanese Walbro and others. These top developments are hard to beat. Therefore, most Chinese manufacturers copy the best models.

Some are nameless, from an unknown manufacturer and do not even have markings. They are simply offered for a specific chainsaw model. For example, a carburetor for a Stihl MS 361 chainsaw.

Others have brand names of well-known brands.

Still others have their own catchy names - in Russian transcription King Kong, Technopark, Rezet and others.

User manual

The Taiga chainsaw described above must undergo maintenance from time to time. In this case, safety precautions must be observed. It is necessary to begin such work by turning off the engine, while you need to be in a specially equipped and adapted place for this. The remaining oil and mixture must be drained into a special container, and during operation it is recommended to use only serviceable tools. After completing maintenance, cleaning materials remain, which should be collected in a metal box and then removed from the workshop.

The Taiga chainsaw, reviews of which will allow you to make the right choice, should be serviced in a work area that is first cleared of foreign objects. It is recommended to test run the equipment engine without a hub with a drive sprocket. This must be done indoors in the workshop.

The Taiga chainsaw must be properly re-opened. To prepare for work, you need to remove the spark plug ignition wire insulator, and then unscrew the spark plug from the cylinder. With the help of a starter, the engine crankshaft is turned, and then it is necessary to install the piston to the lowest point. Approximately 50 cm3 of pure gasoline is poured into the cylinder through the spark plug hole. The chainsaw should be in an inclined position towards the fan. This will allow gasoline to enter the crankcase.

Replacing the jet

The selection of carburetor jets is carried out according to the markings. The number of each part in the set must correspond to the diameter, according to the table. When choosing a set of carburetor parts, decide what power and take-off speed will suit you. If you are setting nominal dimensions, then everything is simple - you must first select a kit. This is the most important job when purchasing. It should be remembered that 80% of the parts on the market are from China

Pay attention to this when choosing them. Then you can make repairs

To carry it out we will need to remove the carburetor from the engine. This will make further work more convenient

The carburetor removal diagram is described in other articles on the site; the only thing you need to pay attention to is the gasket between the carburetor and the engine housing

After removing the carburetor with a screwdriver, unscrew the screws securing the cover. We remove it and use a flat screwdriver to unscrew the fuel and air jets. On air ones, it is necessary to disconnect the emulsion tubes. Then new parts are installed or old serviceable jets are cleaned. For greater confidence, it is necessary to calibrate the jets on a special stand. “Incorrect” parts should be removed, but this operation cannot be performed independently.

Before installation, all carburetor parts must be washed in cleaning liquid, dirt and carbon deposits removed, and all channels cleaned. We are starting to install new jets. In this case, the correct location of each part of the mechanism must be observed. The jets on the carburetor must be placed according to the markings.

After assembling the device, install it on a new gasket and tighten the fastening nuts. Primary adjustment and tuning is carried out using the mixture saturation and idle speed adjustment screw. These operations will allow you to start the engine. We connect all the hoses and wires, install a new air filter. We make sure that all parts are in place and securely fastened. We test run the engine. Now we need to adjust the operation of the motor and warm it up.

After looking at the engine temperature data, we adjust its operation.

Having completed all the operations of installing jets and adjusting the carburetor reliably and in compliance with all instructions, think about how much fuel you will save.

How to flush a chainsaw carburetor?

You can clean the carburetor on a chainsaw using any aerosol cleaner. The brands Mannol, Hi-Gear and Nowax have proven themselves best. These compounds are good at cleaning the walls and parts of the carburetor from accumulated dust, carbon deposits and hardened resin.

Both Chinese and German carburetors are washed in the same sequence.

Cleaning the carburetor on a chainsaw is performed in the following order:

First, you need to drain the used fuel remaining in the fuel tank. Next, you need to unscrew the mount and remove the protective cover of the chainsaw body, and also remove the standard air filter;
Next, you need to remove the hose responsible for supplying fuel. To do this you will need to open the latches. After this, you need to unscrew the fasteners and remove the top cover of the factory assembly housing;
Next you will need to remove the cover with the blue gasket, which plays the role of a fuel pump membrane. Near the body there are brackets in the form of springs. They will need to be removed and the screws removed;
Then you need to unscrew the screw and carefully remove the needle valve. Directly below it is a built-in spring, which also needs to be removed. After this, you need to pull out the damper and the standard axle, carefully pulling them along towards you;
After this, you will need to remove the drive arm, as well as the throttle body and its factory axle;
All extracted parts of the chainsaw carburetor will need to be laid out on paper and their integrity checked. If necessary, worn parts must be replaced;
Next, all dismantled parts must be washed with a spray can. The same must be done with the float chamber and carburetor body.
After complete drying, all parts must be installed in the reverse order.

After washing, the carburetor will need to be installed in its regular place in the chainsaw. Next, you will need to start the garden tool and observe its operation at idle and maximum speed.

Preparatory work

We warn you in advance that you can adjust the carburetor when:

Spark plugs are working properly
The ignition is set correctly
The fuel pump is working properly
The required gap is set on the device to automatically interrupt the current in the circuit.

It is also recommended to clean the carburetor itself, wash it of carbon deposits, and clean all channels and jets. In general, it is better to buy a repair kit, which includes all consumable parts, including jets, and after washing, install everything new, including gaskets.

After cleaning, carefully put everything back together and be sure to pay attention to the gaps, they should be within normal limits.

Chainsaw. A useful and sometimes simply necessary tool for the owner of a private home. It has a high degree of independence and can be used in field conditions where there is no possibility of connecting to the mains. For some craftsmen, a chainsaw is one of the main devices that performs large volumes of work almost every day. Such loads throw off the factory settings for all important engine components.

The operating mode is often changed by the carburetor, which must be reconfigured. Without an idea of the design and operating principle of this element, it is impossible to adjust it correctly. This issue concerns many users who work closely with chainsaws, so it will be useful to consider this more carefully.

How to install a saw made in China?

Adjustment tools

To adjust the carburetor, you will need Phillips or slotted screwdrivers of varying lengths or thicknesses. The size depends on the design of this unit and the characteristics of the engine assembly. It should be noted that some manufacturers produce carburetors designed for use with special tools.

In particular, installation of Husqvarna carburetors and other imported tools may require a special screwdriver. It is advisable to clarify this issue even when purchasing a chainsaw, so that you can purchase the necessary additional equipment in advance.

In addition, washed gasoline or acetone will be needed to flush and clean the device. They are used to clean the external surfaces of the carburetor. All internal channels are washed with kerosene, diesel fuel or white alcohol. Before washing the carburetor, remove all rubber or plastic parts that may come into contact with aggressive chemicals.

Wrenches or ring wrenches are used to disassemble the carburetor. Washing of internal channels is carried out in specially designated baths; sometimes plastic syringes are used for this.

Device

Taiga 245 is a modern chainsaw, made in a plastic case made of impact-resistant material. Not afraid of falls, impacts of medium strength, because... the main part of the elements is made of metal. It is worth noting its heavy weight - 8.95 kg not including fuel. Similar saws weigh significantly less.

Saw dimensions: 900 x 280 x 300. Supplied complete with a saw set based on a 40 cm bar and a chain with a pitch of 9.3 mm.

The Taiga chainsaw is based on a 2-stroke gasoline engine with a power of 2.6 kW, which is achieved when the crankshaft rotates at 7000 rpm. The working volume is 75 cubic centimeters. The piston group cylinder is not hardened, this reduces the service life of the chain saw. This criterion is important for large volumes of work, where the saw operates under load for a long time, almost without stopping. In everyday use, it is not critical whether the piston is hardened or not. The piston size is 50 mm in diameter. The manufacturer recommends using the chainsaw for no more than 40 minutes; after this time, the tool should rest.

The chainsaw is safe for the environment when used with special-purpose oils.

Taiga 245 uses universal motor oil for both the chain and the engine. It is diluted in a ratio of 1 to 20. Yes, yes, exactly 1/20 is a distinctive feature of the Taiga 245 saw. The brand of gasoline is AI-92. As noted above, the same oil is used to lubricate the chain as is used in the engine. In summer, the oil should be diluted with gasoline in a ratio of 1/4. According to reviews from many saw owners, used oil (waste oil), for example from a car engine, can be used to lubricate the chain.

Comparative parameters of the closest competitors

The Taiga chainsaw, the characteristics of which, depending on the modification, allows it to be used for domestic needs and in production, has many competitors. Let's look at the main representatives and their brief parameters.

The German model “Shtil MS-341” is a semi-professional saw, has a power of 2.6 kW, and weighs 4.5 kg. The tire has a length of three hundred and fifty millimeters. There are also many professional models from this manufacturer. Their power can reach 65 kilowatts, and the tire size is 75 centimeters.

“Husqvarna-142” - this unit from a well-known manufacturer belongs to the semi-professional category. With dimensions of 415*310*260 mm, the chainsaw has an engine capacity of 40 cubic centimeters and a power of about two and a half horsepower. It is practical and reliable.

ECHO is a gasoline saw from a young but actively developing Japanese company that has taken its rightful place in the world market. For example, the CS-305WS 14 model, with a power of two horsepower, easily fells small trees, is easy to use, and economical.

Design and principle of operation of a chainsaw carburetor

for mixing oxygen and fuel in certain proportions

The carburetor design is, in general, the same in all saws, with the exception of Chinese-made chainsaws. But, in principle, it would not be superfluous to look at the instrument’s data sheet and study the structure of the carburetor. Its main components are:

tube - an element responsible for portioned air supply by opening or closing the damper;
diffuser - an element located at the inlet through which fuel is supplied and designed to accelerate air flow;
atomizer - a mechanism for injecting fuel into the air flow;
float chamber - a cavity designed to maintain the combustible mixture at the same level. It is from this that the fuel enters the atomizer through the nozzle.

Air flow passing through the diffuser

Signs that indicate the need for carburetor adjustment

There are several signs that the carburetor is not working properly and needs to be adjusted.

The saw is difficult to start and stalls almost immediately after starting. The reason for this is that the fuel contains a low proportion of octane.
Too much fuel consumption, very large volume of exhaust gases, fuel is not completely consumed. Here the reason lies in the too rich mixture supplied to the engine.
The adjustment screws are not fastened due to vibration and a malfunction of the protective cap. This occurs rarely and is due to an attempt to adjust the screws.
Debris (or scale) entering the carburetor due to a broken air filter or the use of low quality fuel. Here, adjustment alone will not be enough; you also need to carry out washing.
Severe wear on the pistons. Tuning the carburetor will help temporarily. In this case, it is necessary to overhaul the engine.

If you have some of the symptoms described above, then it’s time to start adjusting the chainsaw carburetor.

Preparing for adjustment

The chainsaw carburetor is adjusted using three screws:

“H” - screw that regulates maximum speed and main jet;
“L” - screw for setting low engine speeds and idle jet;
the third screw adjusts the idle speed and can be designated differently: “LA”, “S”, “T”.

It is also possible that your chainsaw will have fewer screws, depending on the manufacturer.

So, we have found out the designation of the screws, let's move on to the preparatory procedures. Everything is simple here.

Find information about the angles of rotation of the screws in the data sheet for the saw. This condition must be met, otherwise it may cause engine damage.
Place the chainsaw on a stable surface.
The saw chain should be pointed away from you to avoid injury.
To get to the carburetor, unscrew the chainsaw cover bolts and remove it.
Next, the foam rubber and part of the air filter are removed.

Now you can proceed directly to the adjustment itself, which is carried out in two stages.

Adjusting the carburetor of chainsaws

tighten the screws clockwise

Having completed the procedure, start the engine and warm it up for 10 minutes, setting it to medium speed. Now let's move on to the idle speed screw, which, as we remember, can be designated differently. It must be screwed counterclockwise until the motor starts running evenly. Watch whether the chain moves or does not move. If yes, then the screw needs to be turned counterclockwise. If the engine stalls in this mode, turn the screw slightly clockwise.

Upon completion of all manipulations, be sure to check: acceleration, idle speed and speed.

Checking the operation of the chainsaw after adjusting the carburetor

The following tests will show whether you have adjusted the carburetor on your chainsaw correctly. Gently press the accelerator and if the engine speed almost immediately increases to maximum, then it is working normally when accelerating. By maximum we mean values from 2800 to 15000. If this does not happen, turn screw L one-eighth of a turn counterclockwise.

should be between 11500 – 15000

After these tests, you need to check the operation of the chainsaw in idle mode. We can talk about correct adjustment of the idle speed screw if, when checking, the chain does not move, and the engine quickly picks up the maximum number of revolutions when you press the accelerator. The sound of the engine should come in four strokes.

If during the check you realize that the necessary conditions have not been achieved, the adjustment must be carried out again or contact a specialist.

Advantages and disadvantages

The Taiga 245 chainsaw differs from modern imported chainsaws in its unpretentiousness to the quality of fuels and lubricants, simple maintenance, high level of maintainability, and minimal operating costs.
Winter and summer engine oils of the domestic range can be used as motor and chain materials.
A minimum of plastic components has a positive effect on the mechanical strength of the tool and the reliability of loaded components and assemblies.
The Taiga saw has no significant restrictions on operational loads, so it can be used to work with dense and frozen wood with a diameter of 300-350 mm.

The disadvantage is still considered to be its high weight compared to similar models from other brands. The service life of the cylinder and connecting rod-piston group leaves much to be desired.

In the original proprietary equipment, this Taiga brand chainsaw is equipped with a reliable 2-stroke power unit, equipped with an all-metal crankshaft, a chrome-plated working cylinder and a piston with two standard rings. To reduce vibrations of the running motor, 6 rubber-metal springs are located underneath it.

Technical characteristics of the Taiga 3650 petrol tool include:

engine power – 4.9 l. With.;
fuel/oil tank – 550/260 ml;
bar length/chain pitch – 45 cm/0.325″;
weight with headset and filled tanks – 6.65 kg.

This popular model is pre-equipped with a proprietary bar and cutting chain, the lubrication of which is controlled by an oil pump. Its performance can be adjusted depending on specific tasks. The chain is tensioned using a separately installed side screw.

Without exception, all versions of the Taiga chainsaw are produced on the basis of inexpensive domestic parts and other components.
Taiga brand chainsaws are characterized by low maintenance and do not require the use of expensive motor and chain oils.
The relatively large weight of the tool is compensated by its resistance to mechanical internal and external influences.
Restoring the functionality of faulty household and professional chainsaw equipment is facilitated by a high level of maintainability and a large range of spare parts.
The selling price of branded spare parts and components is several times lower than the cost of imported analogues.

What do the owners say?

The Taiga chainsaw, reviews of which can be found on special forums and trading resources, is in great demand among the population. Particularly popular are the latest models, which combine high performance, durability and low weight. There are no particular complaints about the functionality of this tool. Owners make certain complaints about the carburetor, which often gets clogged and takes a lot of time to clean. In some models, users are not satisfied with the air filters, which they advise immediately replacing with a more practical option.

About this element we can say that it is nylon or made of fabric (felt). The first option is easy to clean, suitable for reusable use, however, it is damaged if large sawdust gets in. The felt filter is more resistant to mechanical stress, but is quite difficult to clean.

It can be noted that the Taiga TBP-4000 chainsaw is a reliable assistant in the professional field, it has significant power with low weight. The introduction of innovative materials made it possible to make it competitive not only with domestic, but also with foreign analogues.

Other modifications from this manufacturer are also quite successfully used in everyday life, private enterprise, public utilities and industry. Some of Taiga's competitors were noted above. Among the domestic units we can mention chainsaws: “Druzhba”, “Energomash”, “Ural”, “Zubr”. Knowing the basic selection criteria and technical features of the device, you can easily choose a device that suits your needs and the fullness of your wallet.

Chainsaw Taiga 3650

An excellent household-grade model that can cope with many tasks related to garden care and firewood preparation.
Also suitable for assistance in construction. The engine is two-stroke, single-cylinder, started manually. The saw runs on a mixture of gasoline and oil in the appropriate proportions. After half an hour of work, it is worth giving the tool a rest to avoid premature wear of parts. The layout of the saw is ergonomic, comfortable, the weight is evenly balanced, which contributes to comfort when working. The manufacturer also took care of the operator’s safety during operation - the chainsaw is equipped with an automatic chain stop system, which protects the user from kickback.

Adjusting the carburetor of a chainsaw away from a service workshop

Instructions on how to set up a chainsaw are in the technical documentation for your tool. However, we will consider typical operations to improve the performance of the tool.

The carburetor adjustment controls are located in an accessible place. To get to them, there is no need to remove the housing cover. In different models, the adjustment holes may be located differently; the illustration shows a typical combination.

The setup procedure is as follows

The “T” screw is intended for tuning the engine in idle mode. On different models it may be designated as “LA” or “S”. The parameter is set by rotating the screw to the left until stable operation at minimum speed. If the engine stalls, you need to turn the screw slightly to the right. The operating shaft should not rotate when operating at idle speed.

If the chain moves out of place during adjustment, unscrew the screw a quarter turn back. The more accurately you catch the moment when there are very few revolutions left before the chain begins to move, the more economical your fuel consumption will be.

Screw “L” sets the degree of acceleration of the chainsaw when you press the accelerator. When you open the throttle, the speed should gradually increase to the maximum value. If the chainsaw stalls under load, this is a sure sign that the acceleration regulator is installed incorrectly. It is necessary to unscrew the screw slightly counterclockwise, achieving smooth, confident acceleration when opening the accelerator.

Screw “H” limits the speed of the working shaft. If you do not fix this value, there will be a failure in the ignition timing, and the chainsaw will start to work jerkily, or, as lumberjacks say, “peddling.” This mode can lead to injury.

In models with a simplified carburetor design, adjustment of acceleration and maximum speed may be absent. In this case, all operating modes of the internal combustion engine are set by the idle screw.

Signs of correct adjustment

At idle speed the operating chain remains motionless. When adding “gas” it immediately starts moving;
When you open the accelerator, the chainsaw engine instantly accelerates. The acceleration process occurs evenly, quickly reaching a maximum;
When the maximum speed is reached, the saw operates smoothly, without jerking. The engine sound is uniform, without detonation;
The exhaust is clean, slightly bluish in color. When the speed changes, only the intensity of the exhaust increases, the color does not change.

To learn how to set up the Partner chainsaw carburetor, watch this video.

If you managed to adjust the carburetor without disassembling the chainsaw body, and the symptoms of malfunctions disappeared, continue working. If not, you will have to remove the top cover of the tool and dismantle the carburetor.

There is an air filter inside the cover. As a rule, this is a piece of foam rubber or similar material. Be careful not to clog or wet the filter. Then carefully disconnect the fuel line and accelerator cable from the carburetor.

They are shown by arrows in the illustration.

Be careful not to allow fuel to get inside the housing. Try to catch any remaining gasoline from the hose using a clean cotton rag. Then you need to remove the carburetor from the body and place it on a clean surface for disassembly and washing.

Try to remember (or better yet, measure and record on paper) the position of the set screws. Otherwise, adjusting the chainsaw carburetor after assembly will be difficult due to mismatch of all settings.

After completing the work, check whether there are any “extra” parts left on the assembly table, and whether the tool is left inside the case.

Care and maintenance

Taiga chainsaws require regular preventative and maintenance. Its timely implementation allows you to extend the working life of the tool with proper performance.

Such activities include the following:

Before each start-up, check the serviceability of the unit, the tightness of the fuel and oil systems, the reliability of fixation of the carburetor with the cylinder, as well as the tightening of fasteners and the tension of the operating chain.
Cleaning the ventilation grille, air filter and carburetor deflector.
Periodically, the filter element must be washed in gasoline or kerosene.
At the end of the work, open and clogged components should be cleaned of chips and dirt.
The working chain is washed in an oil-gasoline mixture, having previously cleaned it.
Small pressed wood must be removed from the tire grooves and sprocket teeth.
You should also clean the oil channel by unscrewing the clamping screw located at the bottom of the crankcase.

Chainsaws and cold: operating rules

The operating conditions of the instruments vary depending on weather conditions. By following useful tips, you can not only get the job done, but also extend the life of the tool.

Operating a chainsaw at low temperatures has its own specifics. In the cold the engine starts much worse. If you act according to the instructions and after the first flashes remove the choke (open the air damper), the engine either will not start or will stall immediately after starting, since gasoline does not evaporate well. You will have to start and warm up the engine on choke. In this case (if the start is unsuccessful), the spark plug may be filled with gasoline, and then you will have to unscrew it and blow it out, or even warm it up.

When working in cold weather, it is recommended to keep the saw (or at least the fuel mixture) in a warm room. Particular care must be taken when storing a chainsaw with a bar and chain attached. If you put a clean, heated chain on a chainsaw and leave it in a cold room (or even worse, outside), then the chain will shrink from the cold (like any object when cooling). In this case, damage to the instrument is possible during startup, and the cost of repairing it will be impressive.

Some models have a winter-summer air intake switch. During the cold season, it climbs above the cylinder or exhaust manifold. This air heating system ensures that the unit will operate without difficulty even at low temperatures, preventing the carburetor and air filter from freezing.

Maintainability

Specifically, many potential buyers are attracted by the possibility of independent, affordable maintenance and major repairs. The independent solution of adjustment and repair problems is facilitated by a highly informative instruction manual and spare parts available in the range and price range.

Timely and fully completed home repairs can reduce operating costs by almost half and reduce the level of dependence on service and repair structures.

Advantages and disadvantages

The Taiga 245 chainsaw differs from modern imported chainsaws in its unpretentiousness to the quality of fuels and lubricants, simple maintenance, high level of maintainability, and minimal operating costs.

Summarizing

The Taiga 214 chainsaw is well suited for working in a garden or summer cottage, as well as for working on construction sites and during logging. It has all the advantages of a modern tool and is quite easy to repair. Due to the fact that it is produced on the territory of the Russian Federation, spare parts for it can be found almost everywhere. Taiga 214 can be an excellent helper around the house.

Gasoline portable saws of the Taiga brand are well adapted to perform complex tasks in different operating conditions. They compare favorably with most analogues due to their durability, ergonomics and relatively inexpensive maintenance. Gas powered tools from the Taiga brand are equipped with everything necessary for intensive work at home and in forest felling. During operation, they show an even cutting line even when working under increased loads. This allows them to be actively used for construction purposes.

Overview of the characteristics of various modifications

The Taiga line of chain units includes the following units:

for home use (low power operation, up to 1.7 kW);
semi-professional (work at medium power, up to 3 kW, with intensive regular operating loads);
professional (work at high power, up to 6.5 kW);
Gasoline sawmills Taiga with autonomous engines and maximum efficiency of lumber output (operation at power up to 20 kW).

The technical characteristics of the Taiga chainsaw meet safety requirements; the design has a large strength margin and resistance to any load.

Features of the Chinese chainsaw carburetor

Their design and parameters differ depending on the power and model of chainsaw they are intended for. All of them are almost identical to the original carburetors in design, but not always in quality. Today, all Chinese products cannot be considered 100% rubbish. In turn, according to their quality, they can be divided into three groups:

Poor quality. Unsuitable alloys are used which oxidize, crumble and break. There is no accuracy of fit, the calibrated holes do not correspond to the required values, which leads to excessive consumption or lack of fuel in the combustion chamber. Critical parts quickly fail. Plastic parts quickly become rough or, conversely, become softened by gasoline and stop working. The axles and wire rods are bent, the threads of the fasteners are torn off. Such products are the cheapest. They are made in semi-handicraft industries using adapted equipment. As a rule, they do not have a name or marking.
Carburetors are of average quality. These are factory assembled products. They do not skimp on alloys; they have established continuous production with quality control. These are fully functional carburetors that can have a service life even longer than that of the entire chainsaw.
High quality carburetors. First of all, these are products from global manufacturers whose facilities are located in China. Geographically, they can be considered Chinese, but they are made using the technologies of the company that owns the brand and values its reputation. For example, Japanese Walbro carburetors are produced in China.

In addition, among Chinese manufacturers there are those who rely on high quality. They invest heavily in powerful production facilities, register their own brand and work on its reputation.

The lineup

Initially, several versions of the chainsaw were created on the basis of the ZID, which differed:

engine power;
productivity;
efficiency.

Heavier and more powerful ones were intended for industrial use. It is worth noting that the basis for all subsequent products in the line was 1 development: Taiga 214. Today the plant produces several improved models, lighter and easier to operate.

Chainsaw Taiga 214

Modern chainsaws are equipped with additional functions, such as soft start, emergency stop, continuous fuel supply, etc. Another difference is weight; chainsaws have become lighter due to the replacement of heavy metal parts with durable and lightweight plastic.

The Taiga chainsaw range includes:

Taiga 214. First model. Intended for industrial and economic use.
Taiga 245 (semi-professional saw for household use).
Taiga BP-3650 (household model).
Taiga BP-3850 (semi-professional tool).

Chainsaw Taiga TBP-4400 1

Taiga TBP-4000.
Taiga TBP-4400/1.
Taiga TBP-4500.
Taiga TBP-6300 (professional saw).

The first models 214 and 245 were developed back in the USSR and for that time they were powerful, reliable saws. Today these devices are morally outdated. It is unprofitable to use them in construction and industry. As for more modern models, they are recommended to be used for domestic needs. Some chainsaws, for example, TBP-4000, are not designed for cutting branches, as they are too heavy and cannot be used with outstretched arms.
