Instructions for chainsaw Taiga-245. Recommendations for operating chainsaws. chainsaw

One of the first Russian models of chainsaws that had a modern appearance and the ability to use the tool regardless of location in space was the Taiga 214 saw.

In this article we will look at its purpose, technical characteristics, adjustment capabilities and methods for eliminating basic faults.

Adjusting the carburetor of the Taiga 214 chainsaw

Carburetor adjustment must be carried out during the break-in period, to reduce the maximum number of engine speeds, as well as in winter and in the event of malfunctions related to the quality of the fuel mixture and its quantity.
A small slotted screwdriver is required for adjustment. The idle speed adjustment screw is designated by the letter “X”, the low speed screw is “P”, the remaining screw is responsible for the quantity and power at maximum speed.

For initial adjustment, it is necessary to set the low and high speed screws to the 1¼ position from the fully tightened state, then start the chainsaw, let it warm up and carry out the final adjustment of the screws until maximum speed and power are obtained.

Determining the cause of the non-working condition of the Taiga-245 chainsaw.

Two days of fiddling with the chainsaw was enough to diagnose it, and the time for repair came in the evening of the second day. We have identified two reasons for the inoperability of the Taiga-245 chainsaw .

• 1. The segment key of the magneto flywheel is broken.

We were a little upset. We made a new one. The source of the material was an old support wheel pin from a ZAZIK.

• The workpiece was cut to the required size.
• Without effort, constantly cooling in water, they ground it on an emery stone.
• Adjusted to the required size.
• We polished it with a sharpening stone and installed the resulting key in its place.

How was the broken segment key determined? When trying to start the engine, we noticed a kickback, indicating early ignition timing. We also noticed rare flashes in the muffler or carburetor.

• 2. The volume of fuel in the working chamber of the carburetor does not correspond to the amount of fuel consumed by the engine in all modes.

The source of the cause was the spring of the rocker arm, which opens the fuel valve at the moment of discharge and the deformation of the lever of the rocker arm itself.

In our opinion, the constant compression of the spring during operation of the chainsaw led to its slight deformation, but sufficient to change the operation of the carburetor and thereby disrupt the operation of the chainsaw engine.

The rocker arm also turned out to be slightly bent and, when fully pressed by the diaphragm pusher, it could not fully open the fuel valve. The engine did not have enough fuel under load. But because of the soft spring, when trying to start the engine, there was so much fuel that the spark plug was flooded and, naturally, starting the engine was the most stressful and time-consuming process.

• We selected a new spring of the appropriate diameter and with a little more rigidity.
• We bent the rocker arm 1mm-1.5mm towards the pusher.

How was the change in the amount of fuel in the carburetor determined?

• Lack of stable engine idling.
• When tilting the chainsaw during a stall or when moving the chainsaw from the starting point to the workplace, the engine changed speed and stalled in a few seconds, after which the chainsaw could be started again with great difficulty only after blowing out the cylinder or after the chainsaw had stood for 20- 25 minutes. By the way, the fuel tank breather was not clogged and the check valve in it worked perfectly.
• After sharply pressing the accelerator handle, the chainsaw engine did not suddenly reach maximum speed.
• After lowering the accelerator, the engine did not go into idle mode, but smoothly slowed down its speed, after which it stalled, even when the accelerator (throttle) was pressed back sharply.

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:

1. Check the fuel filter.
2. 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.

After dismantling the muffler, be sure to plug the exhaust hole with a rag to prevent foreign objects from getting inside the chainsaw.

Before installation, do not forget to dry the muffler with a hairdryer.

Care and maintenance

Before starting operation, you must read the instructions, safety precautions, check the technical condition of the unit and act in accordance with the manual.

Main malfunctions and ways to eliminate them:

1. Presence of burrs on the working surface. Clean with a file or emery wheel.
2. The tire is bent. Perform straightening.
3. Reduced sawing efficiency. The teeth are sharpened, the lubrication channels are cleaned, and the chain tension is adjusted.
4. The chain is clogged. Wash with gasoline.
5. Stiff rotation or jamming of the sprocket. Wash the roller bearing with gasoline and lubricate it.
6. The motor does not produce the required power. If the piston rings are defective, remove the cylinder, clean the rings and the piston from carbon deposits, wipe it, and lubricate it with auto scrap. If the crankcase rubber seals are worn out, replace them.
7. There is a spark, but the saw does not start. Check for clogging of the fuel line.

Currently reading: Chainsaw forester device

The engine does not start for the following reasons:

1. Lack of fuel in the tank.
2. Spark plug faulty.
3. Oily electrodes or violation of gaps.
4. No spark.
5. Fuel intake clogged.
6. Rich oil saturation.

The process is performed by 3 screws, which are located on the deflector and fan cover:

• screw “X” is responsible for adjusting XX;
• screw “P” - for low speed;
• the latter - for power and rotation speed.

When making the first adjustment, which occurs in a muffled state, the low and high speed screw is turned out by 1 and ¼. Then start the saw and warm it up.

The final adjustment is carried out with the engine running and warm, and the ratio of the composition and quantity of the fuel mixture is changed with screws.

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:

1. 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.
2. Cleaning the ventilation grille, air filter and carburetor deflector.
3. Periodically, the filter element must be washed in gasoline or kerosene.
4. At the end of the work, open and clogged components should be cleaned of chips and dirt.
5. The working chain is washed in an oil-gasoline mixture, having previously cleaned it.
6. Small pressed wood must be removed from the tire grooves and sprocket teeth.
7. You should also clean the oil channel by unscrewing the clamping screw located at the bottom of the crankcase.

DIY chainsaw repair Taiga

To repair a Taiga chainsaw, it is extremely important to correctly diagnose and identify the causes of problems. If we consider in general terms the malfunctions of the Taiga chainsaw, then we can safely divide them into two categories:

• Repair of a Taiga chainsaw associated with a breakdown of the internal combustion engine;
• And a malfunction of the chainsaw’s ignition system, as well as the fuel supply system.

Other breakdowns of the Taiga chainsaw, such as a failed clutch, a badly worn tire, etc., will not be considered. Since this variant of the Taiga chainsaw malfunctions, the tool starts normally and does not stall after starting.

The Taiga chainsaw may not start for several reasons. But sometimes, even after the chainsaw has started, you can observe interruptions in its operation, a drop in power, etc. Therefore, in order to properly repair a Taiga chainsaw, you should use a method to eliminate malfunctions of certain of its components.

If the Taiga chainsaw engine stalls after starting or refuses to start at all, then you should start looking for a malfunction, primarily in the operation of the chainsaw ignition system. Here you should check the functionality of the Taiga chainsaw spark plug, as well as high-voltage wires.

Inspecting a chainsaw's spark plug can tell you a lot, including why the Taiga chainsaw engine won't start. If the tip of the spark plug is dry, this indicates that the fuel mixture is not entering the chainsaw engine cylinder. You need to try pumping up the fuel with a pump, the button of which is usually located near the power button of the chainsaw.

At least a similar power button is present on the Ural chainsaw. Therefore, if you are repairing a Ural chainsaw, you should check the presence of fuel in the gas tank and be sure to pump it up until the rubber button casing is completely filled with fuel.

On the contrary, if the spark plug of the Taiga chainsaw is splashed with fuel and wet, then this indicates an incorrect carburetor setting. Correct adjustment of the Taiga chainsaw carburetor is performed as follows.

User manual

The instructions for the Taiga chainsaw also contain information on how to start and stop the engine. To do this, the tool should be given a stable position, and then the throttle lever should be secured with a special button in the central position. The cold start lever is pulled out towards the operator until it stops, after which the ignition switch is set to the “Off” position.

Holding the tool with your left hand by the handle, you need to step on the side of the rear handle with the toe of your right foot. With the operator's right hand, pull the starter handle until it engages the flywheel. Then the cord is pulled out sharply. This operation must be repeated until the first flash occurs in the engine cylinder.

The most common breakdowns of the Taiga 214 and their elimination

As with any equipment, breakdowns sometimes occur in the Taiga chainsaw; we will list the most common ones and consider how to diagnose and fix the malfunction.

Engine won't start

The most likely reason that the engine does not start is the lack of a spark between the spark plug electrodes or an interruption in the fuel supply. In this regard, the following actions must be taken:

1. Check the spark and condition of the electrodes on the spark plug and, if necessary, clean or replace it.
2. Check the presence of fuel in the tank.
3. Inspect the chainsaw for fuel leaks through torn fuel lines, and repair if found.
4. Clean the fuel filter
5. If the spark plug is wet and there is a spark on it, the most likely cause of the breakdown is a poor-quality fuel mixture. To fix this, you need to adjust the carburetor.

The engine does not develop full power

1. It is necessary to check what position the saw chain brake is in; if it is on, turn it off.
2. If the Taiga 214 confidently holds idle speed and at the same time does not develop full power, the reason is most likely in the carburetor settings. The high speed screw needs to be adjusted.
3. Check the engine crankcase for leaks, if the idle speed fluctuates and eliminate them if detected

Frequent malfunctions

One of the first Russian models of chainsaws that had a modern appearance and the ability to use the tool regardless of location in space was the Taiga 214 saw.

Let's look at the main malfunctions of Taiga chainsaws, which you can independently diagnose and fix:

1. There is no spark at the spark plug contacts. Reasons: a faulty spark plug or ignition module, a broken high-voltage wire or a loose cap, the gap between the coil and the flywheel is not adjusted.
2. There is a spark, but the saw does not start. Reasons: clogged fuel line or carburetor, depressurization of the crankcase, oiling of the fuel pump membrane or the main chamber of the carburetor.
3. The saw starts and stalls. Reasons: strong air leaks into the crankcase, disturbances in the fuel supply system.
4. The saw runs at idle, but stalls when you press the gas. Reasons: clogged main chamber injector valve, clogged fuel line, air leak into the carburetor.
5. The chain rotates constantly. Reasons: clutch spring burst, increased idle speed as a result of incorrect carburetor adjustment.
6. The saw spontaneously increases speed when changing its position in space. Causes: rear shock absorber is torn, carburetor is incorrectly adjusted (not enough fuel).

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).

• 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.

Conclusion

Chainsaw Taiga 245 is perfect for home use. It still lacks reliability for working in the forest and is hampered by excess weight. The chainsaw is easy to repair; most faults can be fixed with your own hands. Spare parts are available and not expensive. The affordable price covers all the shortcomings and makes it an excellent mid-range saw in its class.

The sawing apparatus of the Taiga-214 chainsaw consists of a shortened solid cantilever-type bar, a PTSU-10.26 saw chain, driving and driven sprockets. The tire is attached to the crankcase attachment with two studs. The tension of the saw chain is adjusted using a screw located at the end of the platform under the bar; When screwing it in, the saw chain is tensioned.

Chainsaw "Taiga Profi TBP-4000": description

This tool is a saw that runs on gasoline and has a high build quality thanks to the use of wear-resistant elements. The unit is used for all kinds of work related to felling trees, clearing clearings, forest plantations, construction, sawing and harvesting wood.

The Taiga Profi-4000 chainsaw is equipped with a productive and reliable oil pump, which guarantees the supply of appropriate lubricant to the working part of the tool (chain). This model is equipped with a Japanese Walbro carburetor, designed for uninterrupted operation at different angles, ensuring quick engine starting.

The modification in question is easy to maintain, thanks to quick access to the spark plug and air filter. The body part is made of durable plastic, and emergency chain braking is provided. Due to shock absorbers, vibration of the device is reduced. The model is equipped with an additional bar and chain.

Cost of spare parts

If you purchase a Taiga chainsaw, you may need spare parts for it during operation. For example, a steering shock absorber will cost 196 rubles, while a starter drum costs only 80 rubles. The additional shaft costs 134 rubles, but the muffler costs 224 rubles. You can purchase an electronic ignition for 548 rubles, a piston pin lock for 200 rubles.

You can purchase a chainsaw chain for 880 rubles, while a piston will cost 485 rubles. The piston group costs much more - 2800 rubles. A crankshaft bearing will cost 196 rubles, a set of oil seals costs 228 rubles.

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.

Structural advantages

A characteristic feature of the entire model range is the minimum number of plastic parts, as a result of which the Taiga chainsaw turned out to be quite heavy. The basic technical characteristics of even the very first models largely correspond to modern requirements.

The design of the tool compares favorably with analogues of the same type due to its large margin of safety and resistance to the entire range of operating loads.

Users highly appreciate the maintainability of the entire model range; DIY repairs can be done at home with a minimum set of tools. Spare parts are produced in a sufficient range, and the list of advantages includes the affordable cost of consumables.

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.

Appearance and equipment

The design of Taiga chainsaws is as simple as possible, as is the design. The color of saws is mainly green, but there are models painted in red and orange. Standard delivery contents:

1. Saw set.
2. Tools for repair and maintenance.
3. Plastic measuring canister for preparing the mixture.
4. User guide.
5. Protective glasses.

According to user reviews, the saw set that comes with the chainsaw is of very poor quality; after just a few days of use, it needs to be changed.

In principle, this configuration is enough to assemble the saw and start working immediately after purchase.

Description

Taiga chainsaws are often used in suburban areas to perform various tasks such as collecting firewood and rejuvenating trees. The BP-3850 new model is significantly different from previous versions of the chainsaw line. The manufacturer has improved the design of the bp-3850, thanks to which the weight of the device has decreased to 5.5 kg.

Chainsaw Taiga at work

The length of the working surface is 45 cm. The manufacturer recommends performing sawing work on wood with a diameter of no more than 50 cm. At the same time, reviews from owners indicate the greater power of the device compared to other household models. This allows you to harvest wood of various densities, including frozen wood.

Advantages of the Taiga BP-3850 chainsaw:

• improved engine cooling system;
• automatic oil supply system;
• increased power;
• easier startup;
• vibration damper;
• emergency circuit stop;
• fuel pumping system.

The design of the product is equipped with ergonomic handles, which increases comfort and safety when working with the device.

The location of the engine and starter in relation to the structure makes it easier to start the chainsaw. The vibration reduction system improves working conditions with the device. Country of origin: Russia.

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.

Specifications

Structurally, the Taiga 245 saw is made with a minimum of plastic parts, which negatively affects its weight category; the dry weight of the tool with the saw set is less than 9 kg.

• The drive of the 16-inch saw set is realized from a 2-stroke low-speed power unit with a power of 2.5 kW. The cylinder volume of 75 cm3 ensures stable engine traction characteristics and a sufficient supply of torque in all operating modes.
• The operational feature of the tool is that it works on a gasoline-oil mixture prepared in a ratio of 20:1.
• The oil, which lubricates and cools the parts of the saw set, the bar and the saw chain, is supplied to the cut by a pump with constant output. Its increased consumption is compensated by the low cost of domestic lubricants.

Electronic ignition does not require separate maintenance. The main difficulty for novice sawyers is setting up the fuel supply system.

Chainsaw Taiga 245

Taiga 245 is a chainsaw from a Russian manufacturer, produced at the Degtyarev plant, abbreviated as ZID. The high power of the motor allows it to be used both for work in the forest and for domestic needs. Today, the Taiga chainsaw is obsolete, but continues to enjoy popularity among the country's population. The saw rarely breaks, so let’s look at the main possible breakdowns and how to remove them with your own hands.

Application

Despite its power, the Taiga 245 chainsaw was not widely used by woodcutters (of which there are plenty of reviews about the saw) due to its low fault tolerance. Still, when working in the forest, you need a more reliable tool: Stihl, Makita, Husqvarna. Carburetor adjustment. The Taiga 245 chainsaw is different from a modern chainsaw. The saw found its main use in everyday life. It is perfect for all household purposes:

• cut a slab;
• cut down a small tree;
• saw old boards;
• trim branches;
• buck the whips.

Device

Taiga 245 is a modern chainsaw, made in a plastic case made of impact-resistant material. A photo of this chainsaw can be seen below Taiga 245 chainsaw from the carburetor and. Is not afraid of falls or impacts of medium strength, because... Most of the parts are made of metal. It should be noted that it weighs 8.95 kg, not including fuel. Such 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 internal combustion engine with a power of 2.6 kW, which is achieved when the crankshaft rotates at 7000 rpm. The working volume is 75 cubic cm. The piston group cylinder is not hardened, this reduces the service life of the chain saw. Taiga 245 is a chainsaw with additional carburetor adjustments. This aspect is important for huge volumes of work, where the saw operates under load for a long time, virtually without stopping. In domestic use, it is not critical whether the piston is hardened or not. The piston size is 50 mm in diameter. The manufacturer advises using the chainsaw for less than 40 minutes; after this time, the tool should rest.

The chainsaw is not hazardous to the environment provided it is used with specially designed oils.

Taiga 245 uses universal motor oil for both the chain and the motor. It is diluted in a ratio of 1 to 20. Yes, yes, specifically 1/20 - this 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.

Carburetor

The carburetor of the Taiga 245 chainsaw deserves special attention, because... most of the defects occur specifically in it. The carburetor of the Taiga 245 chainsaw may require additional carburetor adjustment. Taiga 245 is equipped with a floatless membrane-type carburetor KMP-100US, with an integrated pump. The pump supplies fuel from the tank to the carburetor.

Structural components of a chainsaw

All chainsaws are similar in structure, regardless of whether they are made in Europe (ECHO, Stihl, Husqvarna) or domestic (Kedr, Ural). Inside the body there are the main elements - the fuel tank and the engine, and outside there is a starter, a handle, a saw part (tire) with a chain. A sharp tug of the cable starts the engine, and it starts the saw blade.

To begin with, we invite you to familiarize yourself with videos that show how a chainsaw works and how it works:

From time to time, malfunctions occur in the operation of the saw, which require disassembly to eliminate. What can happen to such a simple mechanism as a chainsaw? At least the following:

• Stops starting;
• It starts, but soon stops;
• Stops functioning when cutting;
• Loses its power;

Most problems are associated either with interruptions in engine operation (fuel supply system, exhaust system, ignition, cylinder-piston part), or with malfunctions of other systems and components (clutch, chain brake, tire, lubrication system). Let's look at the most common breakdowns and methods for eliminating them.

A serviceable chainsaw starts with one pull and does not fail to cut

Signs of a faulty chainsaw.

Whatever source of heat warms us from the bitter cold, there is still nothing warmer than the bright Sun or a flaming fire that unites interlocutors, trying to tell us about something interesting through the crackling of the wood burning in it.

Yes, it is easy to get firewood in the forest. They are everywhere. But in order not to run into the forest and look for “twelve months” and ask to warm up by their fire, it is better to prepare firewood for the winter in advance and then, during a severe snowstorm, enjoy aromatic tea with jam and bagels in the house by a warm stove. How can we prepare that very firewood if the previously “friendly” chainsaw already refuses to be friends with us “citing a bunch of sores”?

Here is one example of a failure of the Taiga-245 chainsaw.

The chainsaw was purchased in 2003 and over the following years it served its purpose without fail. Every year, with its help, eight to twelve stackers of firewood were prepared. There were minor operational problems due to inappropriate gasoline. Over the entire ten years of its existence, only the starter cord, compression rings and spark plug were replaced.

In the last harvesting season, Taiga flatly refused to work. It started with great difficulty. There were no high engine speeds or idling. The power was not enough to cut even small round timber. It could stall at any moment and then not start at all, as if screaming: “It’s not my fault!” I can not take it anymore!'

What to do? Where to start repairing a chainsaw? We decided to start researching and observing her work in order to identify all the “sores” based on the symptoms.

What is the difference between the household model and the professional version?

Low-power modifications have a limited service life, low weight and size. They are designed to operate in a country house, in a garden or in the courtyard of a country house; they can work continuously for no more than an hour, but are lighter in weight and more economical. Semi-professional Taiga chainsaws can operate up to eight hours a day. They are used to fell small trees and cut almost any wood. Industrial models are designed to work for 15-16 hours. At the same time, domestic saws are made taking into account the characteristics of a difficult and harsh climate. Compared to foreign-made analogues, this tool has a reasonable price.

The main criterion for choosing a chainsaw is the ratio of mass and power of the unit. The higher the second indicator, the more substantial the weight of the device will be, which is not so easy to work with. Therefore, you need to consider your needs and the capabilities of the tool. The category of professional saws includes devices with a power of two to six kilowatts (depending on the region of work, the hardness of the wood and the type of wood). The chain pitch for such modifications starts from 0.4 inches.

The domestic chainsaw “Taiga Profi” has the following technical characteristics:

• power – 4 kW (5 horsepower);
• weight – 5.5 kilograms;
• gas tank capacity – 0.55 liters;
• gap between chain teeth (pitch) - 0.325 inches;
• tire length – 450 millimeters;
• start type – manual.

For comparison, below are similar characteristics of the semi-professional modification “Taiga 52C”:

• the power indicator is 2.8 kW or 3.6 horsepower;
• weight – 5.4 kilograms;
• the tank holds half a liter of gasoline;
• The tire length is 520 millimeters.

As you can see, the industrial model has almost the same weight, but its combination with power is much higher.

Main characteristics of the model:

• type – semi-professional option;
• weight – 8.95 kg (without fuel);
• tire length – 400 mm;
• chain pitch – 9.3 mm;
• Fuel tank capacity is 0.75 liters.

The scope of use of this saw is harvesting firewood, sawing wood, felling trees, pruning branches, and household needs.

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.

“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.

Technical characteristics of the Taiga 214 chainsaw

The weight of the device excluding fuel and lubricants is 8.8 kg. At the same time, the fuel tank capacity is designed for 0.8 liters, and the volume of the lubricant reservoir is 0.3 liters. Overall dimensions of the chainsaw – 857x280x272 mm. The sawing apparatus consists of a 38 cm bar with a driven sprocket, and is complemented by a chain with a pitch of 9.3 mm.

Productivity is about 65 cm3/s, provided that workpieces with a diameter of up to 30 cm are cut. At the same time, fuel consumption is 440 g/hp/h. This is ensured by the use of a 3.5-horsepower engine. A gasoline-oil mixture in a ratio of 20:1 is used as fuel. For these purposes, gasoline grades A-72 or 76 and oil M-8A or AC-9.5 are used.

Noise pollution is within the norms and is limited to 106 dB.

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.
