Chainsaw taiga 245 do-it-yourself repair

In detail: chainsaw taiga 245 do-it-yourself repair from a real master for the site my.housecope.com.

No matter what source of heat warms us from the bitter cold, there is still no warmer than the bright Sun or a bonfire blazing with its heat, uniting the interlocutors, who is trying to tell us something interesting through the crackling of firewood burning in it.

Yes, firewood in the forest is easy to get. They are everywhere. But in order not to run into the forest and not look for ‘twelve months’ and ask them to warm themselves by their fire, it’s better to prepare firewood for the winter in advance and then, in a severe snowstorm, enjoy fragrant tea with jam and bagels at the warm stove in the house. And how can you prepare the same firewood if the previously 'friendly' chainsaw already refuses to be friends with us, 'referring to a bunch of sores'?

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

The chainsaw was purchased in 2003 and over the following years it has performed its purpose without fail. Every year, with its help, eight to twelve stacks of firewood were harvested. Minor malfunctions occurred due to inappropriate gasoline. For all ten years of its existence, only the starter cord, compression rings and spark plug have been changed.

In the last harvesting season, Taiga flatly refused to work. Started with great difficulty. There was no high RPM or idle. There was not enough power to cut even small round timber. It could stall at any moment and then not start at all, as if shouting: ‘It’s not my fault! I can not take it anymore!'

What to do? Which side to start repairing a chainsaw? We decided to start exploring and observing her work in order to identify all the ‘sores’ by the symptoms.

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

1. The magneto flywheel key is broken.

A little upset. Made a new one. The source of the material was the old support wheel pin from ZAZik.

Cut to the required size.
Without effort, constantly cooling in water, they turned it on an emery stone.
Fitted to the required size.
Polished with a whetstone and installed the resulting dowel in its place.

How did you determine the breakage of the segment key? When trying to start the engine, they paid attention to the 'recoil', indicating an early ignition moment. We also noticed rare flashes in the muffler or in the carburetor.

2. The volume of fuel in the working chamber of the carburetor does not correspond to the amount of fuel consumption 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 moments of discharge and the deformation of the arm of the rocker arm itself.

In our opinion, the constant compression of the spring during the 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 the membrane was fully pressed by the 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 candle was flooded and, of course, starting the engine was the most stressful and lengthy process.

Picked up a new spring of the appropriate diameter and with a little more rigidity.
The rocker arm was bent 1mm-1.5mm towards the pusher.

How did you determine the change in the amount of fuel in the carburetor?

Lack of stable idling of the engine.
When the chainsaw was tilted during a stall or when the chainsaw was transferred from the starting point to the workplace, the engine changed speed and stalled in a few seconds, after which the chainsaw saw could be started again with great difficulty only after the cylinder was blown out or after the chainsaw stood for 20- 25 minutes. By the way, the fuel tank breather was not clogged and the check valve in it worked fine.
After a sharp press on the accelerator handle, the chainsaw engine did not sharply gain maximum speed.
After lowering the accelerator, the engine did not go into idle mode, but gradually slowed down its speed, after which it stalled, even when the accelerator (throttle stick) was pressed sharply in the opposite direction.

After our minor repair interventions, we carefully assembled all the disassembled parts of the chainsaw and proceeded to test run it. For this case, we use only low-octane gasoline A-76 (or normal-80).

As a rule, after opening the carburetor, there will be no gasoline in its chambers, especially since the Taiga-245 chainsaw does not have a manual fuel pre-priming pump - a primer. But we are not used to giving in.

With an ordinary medical syringe, a little air was pumped into the tank itself through the breather of the fuel tank, thereby increasing the pressure in it and fuel filled the carburetor fuel pump chamber through the gas line.
We closed the choke, turned the ignition switch to the ‘on’ position and scrolled the starter several times until the first flash. What was our joy when the engine started the first time! Incredibly, it is a fact that slight wear or small deformation of a part can greatly affect the performance of the entire engine.

Then, after warming up the engine, the carburetor was set up for idling and for operating mode at maximum loads.

After we replaced the fuel valve rocker spring, according to the recommendations of the manufacturer, the mode jet screws were set to their original position: idle - unscrewed 2-3 turns from the end point (stop), the work jet screw (working) was unscrewed 5°-10° from stop. The screw for fixing the final position of the damper was screwed in so that the throttle would remain ajar, creating a gap of 2mm-3mm.

To adjust the carburetor, you must try very hard to start the chainsaw engine, and when this happens, do not let the engine stall.

In the first minutes of operation after a test run, you can rotate the idle jet screw to somehow keep the engine warming up. Do not try to check the maximum speed of the chainsaw when it is cold. This is bad for the condition of the engine.

When the engine warms up enough, you can safely start adjusting the carburetor.

By smooth rotation of the idle jet screw, we check in what position it is: too turned out or screwed in from the position of the maximum engine speed.

When the screw is fully in the screwed position, the fuel channel of the jet is completely blocked and the fuel-air mixture cannot form. Starting the engine in this condition is very difficult, and sometimes impossible. When the screw is loosened (counterclockwise rotation), the amount of fuel passing through the jet gradually increases. There comes a moment of ideal saturation of the fuel-air mixture, as evidenced by the maximum engine speed at idle.

In other words, we can say that when the idle jet screw is turned off, the fuel-air mixture is gradually enriched and there comes a moment when the engine speed reaches a certain maximum value for idle mode, and then begins to drop noticeably. This indicates that at the moment the mixture is becoming enriched.

We unscrew the idle screw until, after passing the moment of maximum revolutions, the engine will noticeably reduce its revolutions.
By turning the limit screw counterclockwise or clockwise, we adjust the throttle position.

Since we set the idle speed screw to a rich (rich) mixture mode, when the throttle valve screw is screwed in, the fuel-air mixture will gradually become leaner. The flap will open slightly. The air flow will increase. The engine will start to pick up speed.

The damper must be installed in a position where the engine speed will not increase further. Gradually opening the throttle will cause misfiring and the engine may stall. The mixture becomes lean. Covering the damper enriches the mixture.
We unscrew the screw a little, by 2 ° -5 ° and leave it in this position.
By smooth rotation of the idle speed adjustment screw, we select the position at which the engine steadily keeps idle speed, and the saw chain on the bar does not turn.

The optimal idle mode will be established if the engine receives a sufficient amount of an ideal fuel-air mixture corresponding to its working volume and compression ratio.

Carburetor adjustment KMP-100US chainsaw in the operating mode of the engine it is a little easier and is checked at the beginning at the place where the chainsaw engine is started, then in the maximum load mode.

When we have established a stable idle speed of the chainsaw engine, by gently pressing the accelerator handle we check the ability of the carburetor to provide the engine with a fuel-air mixture for maximum speed.

If the speed is insufficient, then by turning the screw of the working jet 1/10-1/8 counterclockwise from the stop, we achieve the maximum possible engine speed with a smooth sound, reminiscent of the sound of a four-stroke engine.
With a sharp press on the accelerator handle, the engine should also pick up speed sharply. With a sharp release - quickly switch to stable idling.

If this does not happen and a short-term failure is observed, then the screw of the working jet needs to be unscrewed a little more. When, with a sharp pressure on the accelerator lever, the maximum engine speed is not observed and interruptions in operation are noticeable, the adjusting screw of the working jet needs to be screwed in a little.

Screwing in this screw reduces the amount of fuel in the engine's operating mode and the mixture becomes leaner. Eversion - enriches the fuel-air mixture.

And the final tuning stage consists of checking and adjusting the operation of the engine at its maximum load.

And so, our saw steadily keeps idling, has a good response to the control of the accelerator lever. But how will she show herself in work at maximum loads?

They brought a dry beech tree to a log and tried to cut it. The engine slowed down a little and a faint smoke appeared in the exhaust. Rich blend. We screwed in the screw of the working jet a little and lowered the chainsaw with a chain onto a beech log, added gas and our Taiga-245 easily coped with the work with a joyful growl.

The next cut was made with moderate chain pressure on the log and at maximum engine speed. ‘Taiga’ sang smoothly, like new. We sawed about one yardstick of firewood. The chainsaw never stalled in operation and in transient conditions, the maximum speed in the load was maintained, the idle mode did not go astray. We were satisfied.

The chainsaw engine is intended for the 76th or 92nd, pour in the appropriate one. High-octane gasoline requires a higher compression ratio to ignite than low-octane gasoline. In order for high-octane gasoline to ignite in a low compression engine, the engine must be at least warm enough and the mixture slightly rich.

But again: enrich the mixture - do not let the gasoline burn out completely.It turns out increased fuel consumption, soot on the exhaust, overflows for a candle, unstable operation under load and in transient conditions, difficult engine start. We impoverish the mixture - additional heating of the engine and other troubles.

These are just our observations and are not binding recommendations for you. The choice is yours.

Taiga 245 is a Russian-made chainsaw manufactured at the Degtyarev plant, abbreviated as ZID. The highest 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 be popular among the country's population. The saw, rarely, but breaks, therefore we will consider the main possible breakdowns and how to remove them with our own hands.

IMPORTANT. An experienced electrician leaked to the network the secret of how to pay half as much for electricity, a legal way. Read more

Despite its power, the Taiga 245 chainsaw did not find widespread use among lumberjacks (of which there are enough reviews about the saw) due to 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 the modern chainsaw. The saw found its main application in everyday life. It is perfect for all household purposes:

file a slab;
cut down a small tree;
sawing old boards;
cut branches;
buckle whips.

Taiga 245 is a modern chainsaw, made in a plastic case made of impact-resistant material. A photo of this chainsaw can be viewed below the taiga 245 chainsaw from the carburetor and. He is not afraid of falls, medium-strength blows, because. the main part of the parts is made of metal. It should be noted its large weight - 8.95 kg, excluding fuel. Similar saws weigh much less.

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

The Taiga chainsaw is based on a 2.6 kW 2-stroke internal combustion engine, 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 resource of the chainsaw. Taiga 245 is a chainsaw, additional adjustment of the carburetor can. This aspect is important for huge volumes of work, where the saw works for a long time under load, in fact, without stopping. In domestic use, it is not critical whether the piston is hardened or not. The piston size is 50mm across. The manufacturer advises using the chainsaw for less than 40 minutes, after this time the tool should rest.

The chainsaw is environmentally friendly when used with special purpose oils.

Taiga 245 uses universal engine oil for both the chain and the motor. It is diluted in a ratio of 1 to 20. Yes, yes, specifically 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 in the engine. In the summer, the oil should be diluted with gasoline in a ratio of 1/4. According to the reviews of many saw owners, used oil (working out), for example, from a car engine, can be used to lubricate the chain.

The carburetor of the Taiga 245 chainsaw deserves special attention, because. most of the defects are directly related to it. Taiga 245 chainsaw carburetor additional carburetor adjustment can. Taiga 245 is armed with a KMP-100US membrane type floatless carburetor with an integrated pump. The pump supplies fuel from the tank to the carburetor.

The main structural elements of the carburetor:

pressure regulator;
air damper;
throttle valve;
consistency adjustment screws;
fuel pump.

A lot of people asked to make a video on setting up carburetor , and now I have such an opportunity.

Chainsaw carburetor adjustment.Some Taiga 245 chainsaws were equipped with Japanese Walbro carburetors. There is no data for them.No reason to customize the carburetor, because From the plant he comes with optimal adjustments. Additional adjustment of the carburetor may be required when a sharp change of temperature, or after disassembling the carburetor itself. Chainsaw goodluck gl4500m original order at the best price if the carburetor adjustment is not. It costs it strictly according to the instructions using 3 screws responsible for adjusting the supply of fuel-air mixture.The model is semi-professional. Adjusting the carburetor of the taiga chainsaw, if the taiga chainsaw started up normally. Differs in the big weight, the powerful engine, the increased fuel consumption.The main technical characteristics of Taiga chainsaw 245:

Weight without fuel and lubricant: 8.95 kg.

Engine: 2-stroke, 2,6 kW (3.5 hp).

Chain pitch: 9.3 mm.

Fuel tank capacity: 700 - 800 ml.

Chain lubrication tank capacity: 260 ml.

Start: manual.

Fuel consumption - 600 g / kW h.

Tire: 40 cm;

Productivity: from 70 sq. see per second.

Noise level: 105 dB.

The Taiga 245 chainsaw is not eternal and tends to break like any other technique. The design of the saw is simple and allows you to repair it with your own hands almost on the knee by a girlfriend. Consider the main breakdowns.Taiga 245 instruction is the main chainsaw document that you should rely on when repairing. Adjustment and adjustment of the carburetor of the chainsaw 0.1 chainsaw Taiga 245 repair. We strongly recommend learn not only the description, but also content.

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

the engine does not start;
The engine starts, but it works not steadily and / or stall;
works unstable;
does not develop full power.

Most of the listed faults occur in the saw due to problems in the ignition system. As everyone knows, the main element of the ignition system is a candle, therefore, the first thing it is necessary to produce its visual inspection.

If excesses of the fuel mixture are visible on the candles, then it has been “thrown”, it is worth wiping the candle, drying it, putting it back and trying to start again.

Evaluate the color of soot on candles. If it is sand-colored, then the candle is working. Taiga chainsaw - 245 when the carburetor needs to be adjusted when the chainsaw is running. For any other color: black, yellow, red, gray, it should be replaced.

If the candle is dry chainsaws, then problems with fuel supply to the combustion chamber, check the fuel supply system.

If a malfunction is detected in the fuel supply system (dry candle), the first thing to check is:

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

Dirty filter - replace. Recommended replacement interval - every 3 months.

To check, fuel comes or not, you need to remove the hose from the carburetor and will take it to run fuel or not. If the hose is fuel, it means that the problem lies in the carburetor. If fuel is not running, clean the hose.

CPG malfunctions are classified as serious and entail high repair costs. The main causes of CPG problems are the 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 candle, insert the device into its place and try to start the saw and look at the instrument readings. If the arrow of the device is in the red zone (8-9 atmospheres), then 100% piston repair is needed.

Chain chainsaw stops a special brake tape when it is clogged with dirt from sawdust and oil, problems with brake appear. It should be removed the housing and carefully clean from dirt

The silencer over time is clogged with products of the combustion of the sparking agent, which causes difficulties with the removal of exhaust gases. Creating excessive resistance in the exhaust path, the chainsaw ceases to develop maximum revs.Also, the muffler is clogged due to excess oil in the fuel mixture.

For do-it-yourself repairs, you will need to dismantle the muffler, disassemble it and clean it thoroughly. You may need to resort to the help of detergents.

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

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

We offer you to watch a video - a demonstration of the operation of the ZID Taiga 245 chainsaw. A Soviet-era saw cuts a tree with a diameter of one meter. Recommended for viewing.

Chainsaw Taiga 245 is perfect for home use. For work in the forest, she still lacks reliability and excess weight interferes. Husqvarna chainsaw carburetor adjustment on carburetor. Video. Chainsaw taiga pro tbp-4000 in chainsaw taiga 245. Chainsaw carburetor adjustment. The motor saw is easily repaired, most of the faults are fixed by hand. Parts are available and not expensive.

It would seem, why would a summer resident who grows vegetables and fruits need a chainsaw, or an owner of a country house with a small garden and several flower beds? The question disappears when there is a desire to build a bathhouse, update a greenhouse, knock down an old business, or just make a bench for relaxing. Unfortunately, any mechanism periodically needs maintenance and replacement of spare parts, and for this you need to be well versed in the design of the product, in addition, repairing a chainsaw with your own hands will save time and money.

All chainsaws are similar in structure, regardless of whether they are made in Europe (ECHO, Stihl, Husqvarna) or domestic (Kedr, Ural). The main elements are located inside the body - a fuel tank and an engine, and outside the starter, a handle, a saw part (tire) with a chain. A sharp jerk of the cable starts the engine, and that one starts the saw blade.

To get started, we suggest that you familiarize yourself with the video clips that show how the chainsaw is arranged 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;
Starts, but soon stops;
Ceases to function in the cut;
Loses its power;

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

A serviceable chainsaw starts with one jerk and does not fail in cutting

The first thing to do when a chainsaw breaks down is to inspect the spark plug by disconnecting the wire and carefully turning it out with a special key.

Components of the chainsaw ignition system: 1 - flywheel with magnets, 2 - ignition module, 3 - candle, 4 - high voltage wire

The spark plug is unscrewed to check its condition.

Her appearance says a lot:

Dry. Most likely, the fuel mixture does not enter the cylinder. It's not the ignition system, so the candle is twisted back.
Heavily splashed with fuel. The reason for the excess fuel mixture lies either in violation of the rules for starting, or in improper adjustment of the carburetor. The candle is thoroughly wiped, the fuel supply is turned off and the starter is turned on - to remove excess fuel and ventilate the combustion chamber. Then the candle is placed in place and the mechanism is started again.
Covered with black soot. This may indicate the use of low-quality oil, an incorrectly adjusted carburetor, or an incorrectly calculated ratio of gasoline and oil.The candle should be washed, cleaned of soot with a sharp object (awl or needle), wipe the electrodes with a sandpaper and place in place.

When checking the candle, you need to pay attention to the gap between the electrodes: from 0.5 to 0.65 mm is considered normal. A damaged or worn gasket must be replaced.

A large amount of black soot on the spark plug indicates a malfunction in the engine

To be completely sure, you should also check for the presence of a spark. To do this, put an ignition cable on the spark plug, connect the spark plug nut and the cylinder with pliers, start the starter and watch for a spark. If it is missing, the spark plug needs to be replaced. If the new spark plug doesn't spark either, the problem is with the high-voltage wire or a loose connection to the spark plug.

Fuel may not enter the cylinder for the following reasons:

Fuel filter dirty. Remove the fuel hose and check how the fuel flows. If the jet is weak, the filter may need to be cleaned. It is taken out through the filler hole of the fuel tank and cleaned; in case of severe contamination, it is replaced with a new one. As a preventive measure, it is recommended to replace the fuel filter every three months.
Clogged breather (holes in the fuel tank cap). They also check by disconnecting the hose, in case of blockage, clean with a needle.
No or insufficient fuel. There may be several reasons for the failure. The first reason is a clogged air filter. Air ceases to flow into the carburetor in the right amount, in connection with this, due to an overly enriched fuel mixture, engine operation is disrupted. The dirty filter is carefully removed, cleaned and washed in water, then dried and replaced.

Another reason is the incorrect adjustment of the carburetor. Adjustment is made with three screws.

Timely replacement of the fuel filter guarantees a full supply of fuel

The fuel hose and the air damper actuator must fit snugly against the fittings

Throttle lever cable must be in place

During operation, you must use the instructions, otherwise you can only make things worse.

And the last reason is a violation of the integrity of the membrane or clogging of the carburetor channels.

To repair the carburetor yourself, you need to get acquainted with all its details

All parts must be clean, dry and in good condition.

If the engine runs fine at low speeds, but starts to stall at high speeds, the reason may lie in the muffler spark arrester, clogged with combustion products.

remove muffler;
disassemble (there are also non-separable models);
clean from soot using detergents;
dry with a hair dryer;
put in place.

Dry cleaning is unacceptable, as carbon deposits contain carcinogens, the inhalation of which is dangerous to health. After removing the muffler, cover the outlet with a clean cloth.

Interruptions in the operation of the chainsaw signal a possible clogged muffler

To prevent clogging of the muffler, it is necessary to monitor the composition of the fuel mixture. The amount of oil should not exceed the norms recommended by the manufacturer. Poor oil quality also negatively affects engine performance.

Often the engine does not start or does not run at full capacity due to low cylinder pressure. It can be caused by worn pistons or cylinders, slipped piston rings, or worn bearings. You can partially examine the state of the cylinder-piston group (CPG) by removing the muffler and looking into the opened hole.

A compression gauge placed in the spark plug hole will help measure the compression in the engine - based on the results of the measurement, one can also talk about the state of the CPG. Accurate data is obtained only after the complete disassembly of the mechanism. If the piston has chips or scratches, it must be replaced. The piston ring must be clean, free of carbon deposits, and in exactly the right place.

Wear of the piston and crank mechanism is considered a serious problem

Based on the results of measuring compression, one can judge the condition of parts of the CPG

Consider three main faults:

Oil leakage. It should be checked whether the tubes are hermetically attached to the pump fittings and whether they are cracked. Problematic tubes are sealed with sealant or changed.
Insufficient oil supply. Most likely, the lubrication channels are clogged.
The occurrence of cracks in the oil pump housing. A part needs to be replaced.

Here is how the lubrication system is diagnosed:

The chain brake often does not work due to grease or sawdust clogging the brake band and the space under the cover. All parts must be cleared of blockages. Perhaps the tape is simply worn out, then it needs to be replaced.

The operation of the chain brake is restored by mechanical cleaning

Some chainsaw parts wear out faster than others. These include the drive sprocket, tire, chain, anti-vibration elements. For quick replacement of spare parts, it is better to always have at hand. Do not neglect the sharpening of the chain.

Probably many people now have such a tool as a chainsaw among their tools. This is undoubtedly a very necessary tool in the household, but like every tool it tends to break.
One of the most popular chainsaw brands is Taiga 245.

A few key features of this chainsaw:

- Engine - single-cylinder, two-stroke, gasoline;
— Power 2, 6 kW;
- Fuel consumption 600 g KW per hour;
— Overall dimensions 280*900*300 mm;
- Weight - 8, 95 kg.
A photo of this chainsaw can be seen below.

1 ) Engine malfunctions. very often breakdowns occur precisely in the part of the engine and most often this is when the engine does not start, it starts but does not work normally and at the same time stalls, it works unstable, does not gain the necessary power.

Almost all of these problems occur due to improper operation of the ignition system.

Therefore, if any of these breakdowns occurs, then you must first begin repairs with candles. Therefore, you just need to roll up the candle and examine it well.

The wire will need to be disconnected and the candle removed using the correct key. If the spark plug is dry, then there is a problem with the fuel mixture not entering the cylinder.

If the spark plug is very heavily stained with the fuel mixture, then this means that there is a large excess of it. The candle is wiped, dried, then put back in place and the launch is repeated again.

2) Fuel mixture supply. If it was found that the fuel does not enter the cylinder, then this may be due to the following reasons:

- in this case, it will be necessary to create a vacuum in the tank, which will prevent the possibility of fuel leakage
- A large level of contamination of the fuel filter, which is installed in the tank
- Insufficient flow or no possibility of fuel entering the cylinder at all.
In order to eliminate the first two reasons, you just need to disconnect the fuel hose from the carburetor and see if fuel is leaking from it or not.

If this fuel does not flow, then the cause of the malfunction is in it. The breather will need to be cleaned with a needle.

The fuel tank will need to be removed through the filler hole with the empty fuel tank using a wire hook along with a suction hose. It is recommended to change this fuel filter every 3 months.

3 ) Muffler. Quite often, the cause of the malfunction is that the muffler is clogged with the products of combustion of the spark arrester and thus this prevents high-quality exhaust.

In order to repair, you need to remove the muffler, disassemble it and clean it completely using detergents. If the muffler is non-separable, then it will also need to be dried with a hairdryer. When the muffler is removed, it will be necessary to plug its exhaust hole with a rag. Also, the muffler can become clogged if fuel with an excess amount of oil is used.

4 ) cylinder - piston group . The faults associated with this group are very serious.This may be worn piston rings, bearing wear. All these malfunctions lead to the fact that the pressure in the cylinder drops. To repair, you need to remove the muffler and look at the state of the cylinder-piston group. You also need to measure the compression level in the engine.

All this is done using a compression gauge, which is installed in the spark plug hole. The crankshaft is turned by an electric motor.

The pressure gauge should not be lower than 8 - 9 atm. If the indicator drops to 5 atm, then the engine most likely will no longer work.

5) Chain brake. Incorrect operation of the brake chain is due to contamination of the brake band with grease and sawdust. In this case, you need to either clean the under-cover space or replace the brake band.

The operating instructions are produced as follows:

- You need to start with the chain and tires. After a while, 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 would go from top to bottom.

After you need to install the casing. - Then you need to tighten the chain with a key strictly clockwise. The chain should not be too tight, but it should not sag either. After that, the nuts are attracted to the casing.

— Chainsaws are equipped with a handle brake. The brake must be disengaged in this case, that is, the handle must be directed towards you.

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

- After you have finished doing work 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), it will be necessary to lubricate the chainsaw bearings with such a grease.

- If more than 5 liters of fuel are processed on the 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 lever, fuel tank, cylinder, starter, crankshaft, piston, spark plug, chainsaw chain.

Chainsaw "Taiga": reviews on operation, repair, abstractThe moment you decide what you need chainsaw, you need to decide how often you will use it, also for what purposes. Having visited the store, you can find chainsaws of various classes, the most low-powered of them are amateur models that can withstand periodic use. V this case it is worth counting on a power that does not exceed 2 kW.If the loads are more than 40 minutes a day, then you should pay attention to semi-professional models. With the help of them it will be possible to carry out construction, working once a day up to 10 hours in a row. Power in this case rises to 3 kW, the diameter of a tree trunk can be 40 cm. But it will be even more difficult to hold such a tool in your hands, because its weight is 6 kg.Chainsaws of a professional level have a power that reaches 6 kW. This equipment is capable of many hours of everyday workload. For personal needs, it is better not to get such a device, because it costs quite a lot, and the tool will weigh more than 6 kg. Such a load will be tangible for an unprepared master who does not have experience working with similar equipment.Choosing a chainsaw class is not the most important task when buying such a tool. It is also important to agree with the manufacturer, who managed to establish himself in the market for such equipment. The Taiga chainsaw is now known to a not very wide range of buyers, but its cost is affordable, and the tool itself has amazing features.This tool belongs to the semi-professional class and has a relatively small weight, which reaches 8.95 kg. The working tire of this equipment has a length of 40 cm. According to buyers, this is completely enough to cut a 30 cm log. The Taiga chainsaw is powered by a two-stroke internal combustion engine with a power of 2.6 kW.

The chain pitch is equivalent to 9.3 mm. From the annotation, you can realize that you can pour 0.7 liters of gasoline into the fuel tank. As buyers say, this is completely enough to complete tasks in everyday life. From the reviews of home craftsmen, you can realize that this equipment is suitable for:
