Chainsaw Saws Crooked How To Fix
Saw head is badly worn
Noticed a cut along the curve? It is likely that the saw headset has worn out a lot. How can you be sure that this is the case? A visual inspection is sufficient. Dismount the tire and examine its flatness at the point of contact with the cutting element. Examine this area from the end to be able to closely examine the seat groove. In relation to the groove, assess the condition of both sides of the bar. If the saw is used correctly, wear on both sides will be even. But more often than not, one side is grinded faster, which leads to a crooked cut. Only replacing the worn edge will help to eliminate the defect.
Important! The wear will be even if you listen to the recommendations of the manufacturers and periodically turn the tire over. True, not all owners of chainsaws can use such a trick, since sometimes the tire has markings, according to which it can be installed only in one position.
When you have identified the cause of the problem with the curvature of the cut, determined increased wear, diagnose the lubrication system so that after repairs you will not encounter an identical problem. Experienced powertrain service technicians know that if the lubrication mechanism works correctly, the likelihood of (uneven) wear is minimized.
If it is not possible to solve the problem with the chain using machine tools, pay attention to the recommendations on how to sharpen the chainsaw chain with a file.
Careful maintenance of the tool, regular checking of the main components of the device, allows you to quickly find a malfunction. And since the nodes are interconnected in a chainsaw, the quick elimination of one problem reduces the chances of others.
Tire wear how to troubleshoot the belt
If the guide has uneven wear on both sides, it is recommended to replace it. However, there is a way to restore a part, which requires a minimum set of necessary tools. Leveling is done with an angle grinder and a grinding wheel (not a cut-off wheel). First, we check the tire, and make sure that it has uneven wear. How to check the wear of the guide, already mentioned above.
Next, consider the instructions on how to eliminate uneven wear on the guide:
- Install a grinding disc in the spindle of the angle grinder, then fix the angle grinder in a vice
- Make a flat surface on which the guide will be located. It is recommended to use a piece of chipboard as a surface, which must be fixed with a clamp.
- Lean a square and align the wiper blade with the surface
- Start aligning the tire. To do this, place it on the surface, turn on the angle grinder, and carry out its longitudinal movement
- When aligning the guide, it is important to keep it moving at a uniform speed. It is necessary to sew until both edges are the same size. The check must be done with a square.
over, the alignment must be done for both sides of the tire. After completing the work, you can install the headset on the tool and check. It is important to note that aligning a guide that has uneven wear on one side is only appropriate if the groove is deep enough to pass the chain shank. If the groove becomes shallow, then the tire must be replaced.
As you can see from the material, there are many reasons why a chainsaw cuts crooked. However, even a beginner can find this cause and eliminate it if you approach the solution of this issue appropriately. Start checking in order, as indicated in the description, and you will definitely identify the reasons that can be eliminated in different ways.
How to fix chainsaw tilt while cutting
To understand why it takes the chainsaw away during sawing, you need to understand a little theory. Knowing the theoretical points will make it possible to fix the problem with minimal cost, since most often the problem can be solved. So why is the chainsaw drift??
Teeth are unevenly sharpened
Let’s consider the first reason. Those powertrain operators who have read the instructions carefully know that the teeth grind at the same distance. And it doesn’t matter which side they are on. Everyone who remembers this rule when sharpening saves himself from problems in the long run, from the problem of uneven cutting of wood material.
As soon as you notice that the saw is being pulled to the side, check the chain teeth. It is highly likely that it is an illiterate sharpening that is the cause of the problem.
Inexperienced chainsaw operators or those who use a file rarely control the length of the teeth. Even the notorious technique of counting movements made when filed a single tooth does not help. Why? Because the chain wears out unevenly, which means that on certain teeth it will take more or less file movements in order for the sharpening to be of the highest quality (all teeth were even).
How do I fix this problem? Learn to sharpen the chain correctly, do it on time. You need to get in the habit of checking the teeth for wear, and if damage is found, it is recommended to resort to using a special sharpener. You can really get this one yourself. It is these machines that are used in workshops, where for a certain fee the teeth of the tools will be made identical, one to one.
Why is this particular method effective? Because all sharpening will be done on the smallest tooth, the one that has been subject to wear. This ensures that each tooth will end up being the same.
If you want to learn how to properly operate a chainsaw chain, contact a professional. Or learn to sharpen the chain correctly on the machine.
There is, of course, one unpleasant nuance. It is necessary to take into account the fact that you grind on this device even those teeth that have not been damaged, and this leads to a decrease in the resource of the saw headset. To minimize the need for low-wear teeth sharpening, ensure that no metal parts such as nails fall under the chain when working with wood (this happens with old boards).
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 three shanks are fully visible when trying to pull it away from the tire, 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.
Saw chain teeth and chainsaw bar wear
Uneven wear on the teeth of the saw chain is the main reason that the chainsaw is led away during sawing. Most often this occurs when a tooth hits a nail or something similar to it. Naturally, this leads to reduced sawing efficiency. As a result, the master begins to press harder on the saw, thereby increasing the load on the bar and on the chain.
With this sawing, sharp teeth normally cut through a tree, and blunt teeth simply roll over the cut like a car wheel moving over a bump. However, the car has a suspension system, shock absorbers. Therefore, such forcing the obstacle on the car has almost no effect.
The saw does not have such systems. Therefore, the chain, bending under such influences, simply presses on the ribs of the tire, gradually spreading them to the sides. In addition, this is accompanied by increased wear on the chain shanks. If timely measures are not followed, wear will develop exponentially.
Curved sawing due to uneven sharpening of the teeth
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 correctly 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 besides the fact that the chainsaw will be taken to the side, it is possible that the load on the engine will increase.
If the teeth were sharpened by a beginner, then you should make sure after the work done in the correctness of its implementation. Some sawers rely on a simple rule of thumb to file sharpening in the same amount for each tooth. However, this assumption is not true, as the chain teeth wear unevenly. As a result, it turns out that the sharpening of each tooth leads to the restoration of their sharpness, but not uniform wear. When the saw starts to cut crookedly, you need to check all the teeth on the chainsaw for sharpening and even wear.
To exclude uneven chain wear, you should sharpen the teeth in a timely manner, that is, sharpen with a file every 15-20 hours of operation. Once every 2-3 months (depending on the frequency of use of the tool), sharpen using a special machine.
If you are not sure that you are sharpening the chain teeth correctly, then you should entrust this work to a professional. Although it is costly, it is much more efficient. If you want to learn how to sharpen a chainsaw chain correctly, then this material contains detailed instructions for beginners.
Severe saw blade wear
The tire lasts much longer than the chain. However, this does not mean that you can exploit it forever, and not think about replacing it. Usually the guide changes after 2-3 worn chains. Before replacing the chain saw guide, you need to assess its technical condition. If a Chinese-made tire is installed on the chainsaw, then it can wear out faster than the chain. That is why, if a sawing curve is detected with a chainsaw, it is necessary to diagnose the tire.
Remove and inspect the tire to be sure it is worn out. Usually, wear is manifested by a shortened one of the sides. Sometimes it is extremely difficult to detect this visually, so you need to use a caliper. A difference of a few tenths of a mm indicates that the tire needs to be replaced. There is also an easy way to check rail wear with a square. To do this, the tire is located on a flat surface, and a square must be attached to it from the side. If the top and bottom walls of the guide are in contact with the square, then the part is in good order.
Accelerated tire wear can occur due to a malfunctioning oil pump. If the lubricant is supplied with long interruptions, then friction increases accordingly, which means that the parts wear out faster. If the lubrication mechanism works properly, then this significantly increases the service life of not only the headset, but also the entire tool.
Why does the chainsaw cut crookedly? We determine the malfunction and fix it
The chainsaw is a truly unique tool that makes felling and sawing wood easier. 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 determined and eliminated.

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.

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.
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:
- The sawman needs to exert physical effort to keep the tool in a straight direction.
- Fuel consumption increases, which is associated with an increase in the trajectory of the tool passing through the material being cut
- Increased load on the drive sprocket, which leads to accelerated wear
- The tire wears out as the load only increases on one side
- Decreases tool performance
- Obtaining a cut curve. If the forest is being prepared for the manufacture of boards, then crooked trunks are equated to marriage. If the tree is cut for firewood, then in the end, the curved-sawn log will not be very convenient to chop
- Discomfort during work the master quickly gets tired when working with a faulty tool
Why can a chainsaw cut trees crookedly? Many people may 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 is often associated with abrasion of one side of the bar
- Untimely tightened chain
If this kind of malfunction occurs, such as an uneven cut in wood, then it is necessary to resort to its elimination as soon as possible. If you continue to operate the tool with such a malfunction, this will lead to engine wear and the need to repair it.
Let’s consider each type of malfunction separately, and find out how to determine what is the reason why the chainsaw is sawing on its side.
If the saw head is incorrectly selected
Often, most sawers simply do not pay attention to the fact that not only the chain has technical characteristics, but also the tire and the drive sprocket with a crown. All these details must correspond to each other in such a technical parameter as a step. Most chainsaws are equipped with a headset with standard pitch parameters equal to 0.325. The tire, chain and drive sprocket, or rather the crown, must have the same pitch. If one of these parts does not meet one standard, then this will lead to accelerated wear of individual parts and the entire tool.
The tire also has such a parameter as the groove width. The value of this value can vary from 1.1 to 1.6 mm, depending on the power of the tool. It is categorically contraindicated to install a tire with a groove width of more than 1.3 mm on a household chainsaw. A standard chain in such a tire will have too much play, which will lead to accelerated wear of both parts.
Never buy an instrument headset if you don’t know or remember the exact measurements. A chain, bar or sprocket like this may be far from suitable for your tool, and as a result, you will need to change all consumables. To find out the width of the tire, you will need to use a caliper or look in the technical description for the tool.
