Why The Chainsaw Saws Crookedly In One Direction

10 chainsaw malfunctions that you can fix with your own hands 10 chainsaw malfunctions: the chainsaw does not start, the engine stalls or fires, the chainsaw overheats, the chain does not cut, the chainsaw cuts to the side

The chainsaw does not cut under load and stalls

  • Clogged air filter. It is necessary to remove the filter, clean it well or even rinse it, dry it and reinstall it.
  • Incorrect proportion of oil / gasoline mixture. Drain the fuel and re-mix the correct proportion of oil and gasoline.

The engine “shoots”

If during operation there are extraneous sounds similar to shots, then there is a problem with the muffler or carburetor. How do I keep my chainsaw quiet? It depends on which node the fault is in.

Chainsaw won’t start

If there are difficulties with starting a chainsaw, many immediately sin on the carburetor. In fact, there are several options and the cause of the malfunction can be any:

  1. Clogged air and / or fuel filters. The problem is solved by cleaning the filters.
  2. Lack of fuel in the tank. Yes, there is such a reason. Some owners forget about such an insignificant detail as refueling a chainsaw and think that a couple of liters of gasoline will last for six months. In addition, the fuel in the tank should not be stored for more than 14 days, because gasoline evaporates and octane number is lost.
  3. Check the pipe from the fuel tank to the carburetor. It could be clogged or cut off, so gasoline does not enter the tank.
  4. No spark on spark plug. Why there is no spark. There can be many reasons: there is no contact, you need to change the candle or it is flooded. Why he pours a candle on a chainsaw is another question. But if this happens, you need to dry and reinstall, and then check for a spark. If the spark plug is heavily soaked, it is recommended to replace it.
  5. Check muffler for carbon deposits. If there is carbon deposits, thoroughly clean the muffler, but it is still recommended to take the chainsaw to a service center to check the cylinder and piston there, because carbon deposits are a sure sign of improper operation of the elements of the cylinder-piston group.
  6. The carburetor is clogged. How to properly adjust the chainsaw so that the carburetor works well is discussed in a separate article.

If none of the above methods helped, then the reason is more serious. The breakdown of one of the nodes of the connecting rod-piston group. In this case, it is recommended to take the chainsaw to a service center.

The main reasons why the chainsaw is misdirected

If the chainsaw starts to cut crookedly during operation, then besides an uneven cut, we get a number of the following negative consequences:

  1. The sawman needs to exert physical effort to keep the tool in a straight direction
  2. Fuel consumption increases, which is associated with an increase in the trajectory of the tool passing through the material being cut
  3. Increased load on the drive sprocket, which leads to accelerated wear
  4. The tire wears out as the load on only one side increases
  5. Decreases tool performance
  6. Obtaining a cut curve. If the forest is being prepared for the manufacture of boards, then crooked trunks are equated to scrap. If a tree is cut down for firewood, then in the end the curved-sawn log will not be very convenient to chop
  7. Discomfort during work. The master gets tired quickly, working with a faulty tool

Why can a chainsaw cut trees crookedly? Many people might think that the reason is a malfunctioning chainsaw tire, but in fact, there are four main reasons:

  • Incorrect or uneven sharpening of teeth
  • Using a chain, bar or sprocket that does not match in pitch
  • Saw head wear. Often due to abrasion on one side of the bar
  • Untimely tightened chain

If a malfunction such as an uneven cut of wood occurs, then it is necessary to resort to its elimination as soon as possible. If you continue to operate a tool with such a malfunction, this will lead to engine wear and the need for repair.

Let’s consider each type of malfunction separately, and find out how to determine what is the reason why the chainsaw is sawing sideways.

When the chain is loose and how dangerous it is

Every chainsaw needs to be tensioned regularly. If this rule is not followed, the consequences can be very traumatic. Most sawers know what this is about and how to tighten or tighten the chain correctly. Correct cutting attachment tension. When trying to pull it away from the bar, the three shanks are fully visible, as shown in the photo below.

If the chain is slack or over-tensioned, the bar will wear. And not only the guide, but also the sprocket, bearing and motor. That is why make it a rule to check the chain tension before using the tool.

Why does the chainsaw cut crookedly. Identify the malfunction and fix it

The chainsaw is a truly unique tool that makes it easier to carry out felling trees and sawing wood. The main advantage of this tool is a quick set of maximum revolutions, as well as the ability to instantly brake the chain. During the operation of the tool, various malfunctions occur, and one of them is an uneven cut. If the chainsaw cuts crookedly, then this causes inconvenience to the sawer, and also consumes a large amount of fuel. If you are faced with such a malfunction, then in this materials you will learn how it can be identified and eliminated.

Teeth are unevenly sharpened

If the tool cuts to one side, the first step is to check the chain. The teeth on the tool should not only be sharp, but also properly sharpened. Correct sharpening is when each tooth is grinded at the same distance as the previous one. This sharpening method eliminates chain imbalance during sawing. The instructions for the tool indicate that each tooth must be ground at the same distance when sharpening. If this requirement is not met, then in addition to the fact that the chainsaw will be taken to the side, it is possible that the load on the engine will increase.

Why can a chainsaw cut trees crookedly? Many people might think that the reason is a malfunctioning chainsaw tire, but in fact, there are four main reasons:

  • Incorrect or uneven sharpening of teeth
  • Using a chain, bar or sprocket that does not match in pitch
  • Saw head wear. Often due to abrasion on one side of the bar
  • Untimely tightened chain

How to avoid incorrect sharpening

In order to prevent a curve cutting due to uneven sharpening, you can use a special sharpening machine from time to time or in case of severe damage to straighten the chain. Buy a machine and sharpen it yourself or give it to a workshop for sharpening.

The fact is that the machine, during sharpening, adjusts to the most worn tooth, which has the smallest size among all. After sharpening, all teeth will have the same size, which will be equal to the tooth on which the adjustment was made.

Why the chainsaw is being pulled aside

Discomfort during work, decreased performance, increased fuel consumption, curve cut, these are all negative consequences of this phenomenon, but what is the reason?

There are actually only three reasons:

  1. Uneven sharpening of teeth;
  2. Using a circuit that does not meet the parameters of the bus or vice versa;
  3. Increased wear of the chainsaw saw headset.

Using the wrong chain

It’s no secret that a chainsaw tire, like a chain, has several main characteristics, one of them is the width of the groove for installing the chain. The groove width can have several basic dimensions:

  • 1.1 mm;
  • 1.3 mm;
  • 1.5 mm;
  • 1.6 mm.

Imagine that we take a chain with a width of 1.1 and place it on a bar with a 1.3 mm groove. Initially, having tightened it well, we may not notice the differences, but as soon as the tension loosens a little, a gap of 0.2 mm will prevent it from moving evenly along the tire, it will tilt to one side and we will again get crooked sawn material.

Check the width of the chain, you can use a vernier caliper.

To eliminate the malfunction, if the chainsaw tire has not yet suffered much and there is no uneven wear on it, only the chain will need to be replaced. If it already shows wear, a completely new kit must be installed.

Why does the chainsaw cut crooked

Working with a chainsaw, in some cases, you may notice how when cutting a tree trunk with a diameter of more than 30 cm, the tire gradually starts to go sideways. This is especially noticeable when it is necessary to cut large-diameter trunks using the double-cut technique, that is, first sawing from above, and then turning over and finishing to the end.

Lumps, crookedly sawn off with a chainsaw, have an uneven surface, this causes some discomfort when they are split into logs. And the use of such a chainsaw when laying a log house, for example, for trimming bars, is not at all permissible, since the ends will be uneven.
