How to lubricate the chain chain Husqvarna. The specifics of the repair of Chinese chainsaws

Husqvarna chainsaw repair

The main node of the system is the pump. The principle of its work is subsequent. With an increase in the engine speed, the gear installed on the main shaft, through the worm gear, the pump shaft drives in motion. In turn, the rotation of the shaft makes a certain pressure in the oil line, which forces the oil to move along it towards the tire.

The end of the oil channel is located at the place of contact of the tire with the tool card, where there is a longitudinal groove on which its oil channel gets when installing the tire.

A groove is needed to ensure the supply of oil to the tire, regardless of the degree of tension of the chain of the chainships. Simply put, no matter what position the tire is at the time of operation, the oil will fall through the groove through the groove.

Then a chain is included in the lubricant process, on the links of which, depending on the model of the circuit, there is either a groove or a hole through which the oil is accelerated over the entire bus. With an increase in engine speed, the oil supply speed also increases.

Some models of the chainsaws are equipped with pumps, which additionally have the adjustment of the bandwidth, and if necessary, the amount of oil supplied by the lubrication system can be increased or reduced.

Oil does not enter the Husqvarna 142 chain

Why does the oil do not enter the chain of the chainsaw?

If the oil does not enter the chain of the chainsaw in the process, you need to find the cause of the problem. Real reasons affecting such a process will like a lot more. You should disassemble the chainsaw and identify the main problem. The likely prerequisites of this process will be described below.

A prerequisite for the lack of oil supply to the chain during the operation of the chainsaw you will like a few reasons and also to identify them you need to disassemble the chainsaw.

Probable prerequisites for non.fuel non.allowance

Oil on the chain may not enter only if there are 2 breakdowns. They include:

The main reason for the breakdown is the air leak. This can happen due to the depressurization of the oil hose during the operation of the chainsaw. So you need to remove the hose from the hole. This must be done in the area where it is connected to the card. Then the hose sits on the sealant and is installed in the usual position. If this did not help, most likely, elasticity was lost. For the upcoming operation of the chainsaw, it is targeted to replace the hose.

The 2nd reason is the breakdown of the oil pump drive. In the common people, this part is called the worm. When the drive is out of order, the oil will not be supplied to the chain. The oil pump drive is a round plastic ring, whose snuffs are located grooves. The constant introduction of a chainsaw leads to the wear of internal parts, under the influence of which an iron hook, which is a snap of the drive, occurs. After this breakdown, the oil ceases to enter the chain.

To remove problems is an option without the help of others or under the control of professionals.

Features of work allowing accounting (software) of lubrication and oil selection

Fuel tanks are selected exactly with volume. With the greatest production, it is allowed to choose components with a small amount of oil.

Husqvarna 137.142 does not supply oil to the chain.

Even more information about the repair and choice of tools online on our website www.Looktool.Ru are always happy for everyone.

Husqvarna chainsaw repairs: oil supply

Repair of the oil pump on the chainsaw Husqvarna 230, 235, 236, 240 online store Repair.

The fuel system of the chainsaw: 1. fuel filter, 2.7. carburetor, 3. manual pumping pumping pump.

If you correctly adjust the carburetor, fuel will be spent in the permissible volume. Otherwise. it will end very rapidly.

A leisurely reduction in fuel at one time of the operation of a saw is a common process. If it is absent, the chain is not true, because working with a chainsaw can be coordinated. It is necessary not to be able to eliminate breakdowns, but also at the same time without the help of others to identify them.

You can change the intake of fuel manually. The correctness of the lubricant complex of accounting programs is determined by the tire submission method. If oil splashes appear, our client remains established correctly.

Create a cut better with a significant amount of lubricant. If there is work with a soft wood, a small amount of fuel is served.

The chain always must be perfectly lubricated. This will allow to avoid smoke and the upcoming failure of the entire chainsaw. If the oil leaks or does not act at all, it is necessary to identify the cause of the breakdown. It is not recommended to operate the tool before repair.

When choosing fuel, you need to do it right. The desire to save is given that the chain is rapidly breaking. To avoid nasty consequences, you do not need to choose oil, the manufacturer of which is China. Preference should be given to unusual firms. In their own price category, they are significantly higher, at the same time their quality is better.

Eliminating the problems related to the circuit service

In the operation of the chainsaws, you need to look at the lubricant of the chain everywhere. Since this part works in the most languid criteria. The chain is subjected to unchanged overheating, dust and abrasive particles are clogged there. The whole spectrum negatively affects its life. A special lubricant will allow to correct the situation. It is submitted to the chain from the tank, providing that unhindered work.

If at one time of operation there is no lubrication, the highest possibility of overheating remains. When the oil does not come, the chain begins to stretch. At the same time, the possibility of its jamming in other words of spontaneous jumping, under the influence of which a person can get severe injury, is preserved.

The channels through which the fuel supply is carried out, there are variations to be clogged with small particles, therefore it is purposeful to cleanse them at times. It is fundamentally watching the level of oil in the tank. Garbage in the channel becomes a frequent prerequisite for non.work of the brake of the quapi. This can be badly affected by your work.

Continuous cleaning of the channels and the overall care of the chainsaw will allow the tool to work for a long time.

But what to do in this case, if anything remains to do our client, tips are respected, and the oil flows indifferently. You need to make sure of the proper operation of the chainsaw. It is completely possible that she was incorrectly collected. If the breakdown was not detected, it is recommended to take it to the workshop. Sometimes you need to replace the pump, but it is necessary to do this in this case, if the new one drank. Old tools leak due to wear of the tank.

The current state of the chainsaw is able to evaluate only special. In the absence of knowledge or uncertainty in one’s own abilities, it is better to entrust the repair of a tool to a specialist.

Why do you need to configure the Husqvarna carburetor

The factory settings of the fuel unit of the chainsaw of the Husqvarna 137 guarantee the optimal engine power and the economy of the working mode. But during operation, the tool must be translated into summer and winter periods, which requires additional adjustment by the parameters set by the manufacturer. Also, the adjustment of the carburetor is important when there is a decrease in traction, or the number of rolling fuel is not over the better.

Find out how to choose an electric or gasoline trimmer for grass, a lawn mower, a lawn mower, a screwdriver, a jigsaw.

Many owners resort to solving this problem to the help of specialists. But you can carry out the necessary adjustment at home.

To do this, you need to perform the following actions:

• Warm up the engine and tighten the blanket of the idle speed to the stop.
• Then weaken it, turning counterclockwise at 4.5 turns.
• Follow the chain at the time of operation of the motor. If it moves, the adjustment failed. Only specialists of the service center can help in this situation.
• In the case when, after adjusting the carburetor, the engine does not start or immediately stalls, check for the presence of fuel fluid in the consumable tank, as well as the degree of suitability of spark plugs and an air excreted filter.
• When the chainsaw engine stalls with an increase in the load, you need to check the central nozzle. Usually its clogging disables the apparatus.

Chainsaws are an indispensable tool for people living in private households. It is a mechanism consisting of carefully fitted parts and nodes.

Like any mechanism, it needs periodic care and configuration. Especially due to poor-quality fuel. Consider the principles and procedure for adjusting the carburetor of the chainsaw Husqvarna.

The carburetor is one of the important mechanical components that make up the chainsaw. In his tasks. mix fuel with air and supply the resulting composition to the engine. But in the process of the chainsaws, situations arise when the Husqvarna carburetor adjustment becomes necessary. Depending on the reasons, the settings of the carburetor of the chainsaw 142 and other episodes are performed to prevent the following situations:

Since the carburetor affects the quality of the fuel, in the first case, the need for the settings of the carburetor of the saw 137 or other professional series, such as Huskvarna 240 or 260, involves the influence of a sufficient amount of combustible raw materials entering the carburetor to mix the mass of air.

It is known that maximum performance is possible only with a certain ratio of these substances. The second point of adjustment of the gas.rosopyle of the carburetor mixer is due to the lack of incoming air, which causes a lack of inhabited gasoline with its output in the form of dense smoke. Timely change in parameters with your own hands to reduce the amount of fuel injected significantly reduces the consumption of this product.

Repair itself will retain not only the budget, but also the time spent on transportation, and the line in the workshop. The same applies to the replacement of various spare parts in a gasoline tool, such as a chain on a chainsaw or a universal head of a trimmer for grass on a motor pump or oil for electric drives.

The device of the lubrication system

What oils are suitable for lubrication of the chain. classification

For lubrication of the chain of the chainsaw, it is recommended to use such types of oils:

• from the famous world manufacturers (STIHL, Daewoo, Husqvarna and others, there are usually o) on the packaging of such oils);
• Original chain from the same manufacturer (if they are in the assortment);
• with a good biodegradability indicator in CEC-L-33-T-82 (95%);
• with viscosity that meets European quality and safety standards. Example of the Standard: Vitness index 130 DIN ISO 2909, density at 15 ° C. 0.89 g/cm³ DIN 51757, thickening temperature.25 ° C Din ISO

Advantages of high price oils

The composition of branded chain oils includes beneficial antioxidant, anti.corrosion, stabilizing components and additives that contribute to the preservation of the working properties of oil and increase the wear resistance of working equipment in difficult operating conditions.

The quality of branded consumables is a reference. For the most part, these are the products of leading manufacturers of Stihl, Husqvarna, Echo, Daewoo and a number of others. Over the past few years, the qualities of Chinese chain oils produced at state.owned enterprises have noticeably improved.

Owners of chainsaw technology independently decide which oil to use the chain of the chainsaw. In the best option, this is the consumable material adapted to the features of the region’s climate recommended by the instruction manual for this model.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged.

The main components of the details of the lubrication system are:

The most common malfunctions

Repair of the fuel system

The fuel supply system is one of the most difficult in the unit, and therefore it should be treated very seriously and follow certain rules. Gasoline may not enter the carburetor for subsequent reasons:

To clean the saopon, you need to prepare the ordinary sewing needle. In the 2nd case, it will be necessary to dismantle the tank and the substitution of the fuel cleaning filter.

Features of the Husqvarna chain: design, tension

The cutting circuit of the saw of this manufacturer consists of working teeth, limiters of the depth of cutting, fixing the pins. The cutting links made of high.alloy structural steel are more loaded during the file. By design, they are divided into left- and right-handed. The width of the cut determines the distance from the side edges of the left and right links.

DIY chain tension with your own hands

The main feature of the Husqvarna chain is a step that can be measured from the first to the third rivet, dividing the result by two. Due to the fact that in the Western calculus system, an inch, manufacturers in the passports in the inventory indicate a step specifically in inches (25.4 mm). 3/8 inches chains are used for medium power chainsaws, and 4 for more loaded. 4.

One of the important characteristics of the chain is the thickness of the shank, which in most models is 1.3 mm. They are often used on specialized and ordinary amateur tools. The thickness of the links must be agreed with the groove of the tire, since excessive thickness can lead to a break or decline of the chain.

When relaxing the chain, it is necessary to tighten it with the means of the mechanism placed on the side of the unit. Having removed the left side cover (2 bolts) for the earlier, we loosen the Husqvarna chainsaw tire. Then we unscrew the longitudinally twisted bolt, thereby move the guide from the unit. With proper adjustment, the circuit should just scroll, but do not hang out on the tire.

Preventive work on the maintenance of the chainsaw

Sharpening of the saw is performed independently by means of devices and a file or on a machine machine. It is made when the cutting edges, minor chips on the teeth.

Filters change is carried out periodically in accordance with the recommendations of the manufacturer. Air, oil and fuel elements are subject to renewal.

Replacing the spark plugs is performed after a certain time, guided by the requirements of operation.

Fuel gas station. Different manufacturers and engine type determine the composition of the fuel mixture-2 or 4-stroke gasoline engine is seasoned with gasoline with or without oil additive.

complex work is the repair of a piston group, gearbox, clutch, etc. P are carried out as events. Such work is usually carried out in specialized repair shops.

Correctly configured chainsaw is a guarantee of safe and high.performance work. Remember this!

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged.

The main components of the details of the lubrication system are:

• Oil tank located, as a rule, in the engine crankcase.
• Filtering element, installed in the tank.
• Oil wiring, this is a small diameter hose made of oil.resistant rubber.
• The heart of the system is an oil pump.
• Worm gear gears transmitting force from engine to the pump.
• The tire of the chainsaw, it can also be considered an element of the lubricant system, as it has special openings for oil supply, by the way, the chain itself is involved in the transportation of the oil and, accordingly, also has some elements designed specifically to ensure lubrication.

Oil pump for chainsaws: malfunctions and repair

As we said earlier, the principle of operation of the chain lubrication system is the same for benzo- and electric saw. Therefore, it is clear that the malfunctions associated with the oil pump, as well as their causes, will be the same. The malfunction of the oil pump of the chainsaw can manifest itself in only two versions. the oil comes in insufficient quantities or follows where it is not necessary. Let us dwell on the symptoms of a malfunction of the oil pump for the chainsaw and talk to the possible causes of their occurrence. At the same time and mention ways to solve problems.

Insufficient flow of oil on the chain. Insufficient lubrication leads to overheating and pulling the chain. This can lead to jamming and, more dangerous, jumping the chain during the operation of the saw. Reasons why the pump does not give the right amount of oil can be several.

• The easiest and easily eliminating the reason is the clogged channels through which oil is supplied to the chain. Sawdust and other garbage clog them and do not allow them to lubricate the chain normally. Therefore, it is important to clean the output channel and channels on the tire where the oil passes.
• Another reason is a malfunction in the operation of the Plunger of the oil pump of the chainsaw. The plunger rotating captures a certain amount of oil and sends it to the chain. The plunger speed directly depends on the number of engine speeds, that is, the faster the circuit is spinning, the more oil should come to it. The failed plunger must be replaced.

Oil leakage. It must be understood that a slight leakage of oil is acceptable. However, if you find your chainsaw every time in a puddle of oil, it is time to repair.

• First of all, check the tightness of the tubes and fittings of the oil pump. Over time, the tubes can crack. It is best in this case to replace them with new ones, but you can try to close up with a special sealing material.
• If the cause of the malfunction in the crack crack, you will have to buy an oil pump for a chainsaw. such defects are not subject to repair.

Unsuality to the incorrect operation of the oil pump for a chainsaw cannot. However, there may be several options for solving the problem. Proper diagnosis and clarification of the cause of the malfunction is a guarantee of an early solution to the problem.

Your assistant should be the operating instruction. If you have lost it, you can contact the dealer of the company, which you use, will provide you with electronic instructions.

So, before each inclusion of a gasoline chain saw, be sure to make sure that the chain is working, whether its teeth are sharpened, whether it is stretched well (not sagging, but not too tightly stretched, it can be slightly pulled away from the canvas).

You can sharpen the chain using a special machine or file with a special template (depending on which step to the tooth of the chain, there are different templates).

Each time after use, the chainsaw must be cleaned: a chain, a tire, an air filter, a case, cooler ribs, cracks and other grooves are cleaned of sawdust. After using the saw, we turn the tire so that it wear out evenly, lubricate the star (if there are grooves for lubrication in the front of the saw).

With prolonged storage, be sure to drain fuel and oil! The chain and tire form an electrochemical pair, because they rust together, they need to be stored separately.

Novel:

I have a Husqvarna 345 and a problem was found with oil supply. On both sides was in oil and I cannot understand where it is pouring from. On the advice of friends, dismantled the saw, cleaned everything, washed and checked. It turned out to be clogged and because of this the oil did not go along the tire, but sprayed around.

Nikolai:

The oil supply on the electric saw worsened. Began to understand, put a new pump, but nothing has changed. Took the specialist and it turned out that the problem was in the drive of the oil pump. It was replaced and everything was getting better.
