Why Does Your Chainsaw Cuts Crooked?

by
If you’ve noticed that your chainsaw cuts crooked, you know how frustrating it can be to have a tool that doesn’t perform as it should.
Fortunately, there are several ways to fix this problem. In this article, we’ll take a look at the causes of crooked chainsaw cutting and provide some solutions to help you get your chainsaw back on track.

Why Does Your Chainsaw Cuts Crooked

 Technique Matters
 
Before diving into the causes of crooked chainsaw cutting, it’s important to note that proper technique plays a critical role in ensuring straight cuts.
When sawing larger pieces of wood, it’s essential to start and finish the cut in a straight line, without pushing the chainsaw sideways.
This technique helps to avoid prematurely wearing the guide bar rails and warping the guide bar itself.
Also, avoid using the guide bar as a lever while sawing, or forcing it free if it gets stuck in the wood. With proper technique, you’ll reduce the likelihood of crooked cuts and prevent damage to your chainsaw.
 

Causes of Chainsaw Cuts Crooked 

The main causes of crooked chainsaw cutting are related to the chain and guide bar. Here are some possible reasons:

 

Uneven Wear of the Chain Teeth

 
If the length or wear of the left and right chain teeth is uneven, it can cause the chainsaw to cut crooked. This can happen when one of the sides hits a stone or piece of metal, resulting in uneven wear.
 

Improperly Sharpened Teeth

 
If the teeth aren’t sharpened correctly along one side, it can lead to crooked cutting. This can happen when the teeth are improperly filed or when the sharpening angle is not maintained.
 

Unevenly Worn Guide Bar Rails

 
Uneven wear of the guide bar rails can cause asymmetry, where one rail is lower or thinner than the other. This can result in the chain rotating at an angle rather than aligned with the bar, causing crooked cuts.
 

Guide Bar Track Too Wide

 
If the guide bar track is too wide for the chain, it can cause crooked cutting. This can be due to wear or pairing the wrong bar with the wrong chain.
 

Guide Bar and Sprocket Issues

 
If the guide bar is incorrectly mounted or the sprocket is worn out, it can cause crooked cutting. It’s important to ensure that the sprocket/guide bar/chain system works in balance to prevent crooked cuts.
 

Solutions for Crooked Chainsaw Cutting

 
Now that you know the possible causes of crooked chainsaw cutting, let’s explore some solutions to help you fix the problem.
 

Proper Maintenance

 
Good maintenance is key to ensuring that your chainsaw cuts straight. Here are some tips to keep your chainsaw in top shape:
 

Sharpen the Chain

 
Routine sharpening of the chain is essential to prevent crooked cutting. Use a round file to sharpen all the teeth properly with the same length and sharpening angle. If you need to fix a specific problem, such as asymmetrical sharpening, pay special attention to sharpening.
 

Adjust Chain Tension

Check and adjust the chain tension to ensure that it’s not too loose or too tight. Proper chain tension helps to prevent crooked cutting.
 

Lubricate the Guide Bar and Chain

 
Keep the guide bar and chain lubricated to ensure smooth cutting. This helps to prevent wear and tear, reducing the likelihood of crooked cuts. Learn more about how the oil pump works and how to maintain it.
 

Flip the Guide Bar

Periodically flip over the guide bar to even out the wear as much as possible. This helps to prevent asymmetrical wear and crooked cuts.
 
 

 What should I do to prevent my chainsaw from cutting crooked?

To prevent your chainsaw from cutting crooked, you should start and finish the cut in a straight line, without pushing the chainsaw sideways.
You should also avoid using the guide bar as a lever while sawing or forcing it free if it gets stuck in the wood.
Additionally, maintaining good maintenance practices such as routine sharpening of the chain, checking and adjusting chain tension, and keeping the guide bar and chain lubricated can help ensure your chainsaw cuts straight.
 

Why does my chainsaw cuts crooked?

 
There could be several reasons why your chainsaw cuts crooked, such as uneven wear of the left and right chain teeth, incorrectly sharpened teeth, unevenly worn guide bar rails, or a guide bar track that is too wide for the chain.
Additionally, improper mounting of the guide bar or worn-out sprockets could also cause crooked cutting.
 

How can I sharpen my chainsaw’s chain correctly?

 
To sharpen your chainsaw’s chain correctly, you should use a round file to sharpen all the teeth and maintain the same length and sharpening angle.
You can find more information on how and when to sharpen your chainsaw’s chain in the article.
 

How often should I replace my chainsaw’s guide bar and sprocket?

It is recommended to change the sprocket with every second chain replacement and the guide bar with every fourth chain replacement.
However, this may vary depending on the usage and maintenance of your chainsaw.

 

Why is good maintenance important for a chainsaw?

Good maintenance practices not only ensure efficiency but also safety when using a chainsaw.
Proper maintenance can prevent issues such as carburetor flooding and ensure that your chainsaw operates as expected.
 

 

 How do I know if my chainsaw chain needs sharpening?

You can tell if your chainsaw chain needs sharpening if it is not cutting straight, producing sawdust instead of wood chips, or taking too much effort to make the cut.
You can also inspect the chain to see if the teeth are dull or damaged.

 

Can I sharpen my chainsaw chain myself?

Yes, you can sharpen your chainsaw chain yourself with a round file, a flat file, and a filing guide.
However, it requires some knowledge and practice to do it correctly and safely. You can also take your chainsaw to a professional for sharpening.

 

How often should I lubricate my chainsaw chain and guide bar?

You should lubricate your chainsaw chain and guide bar every time you refuel your chainsaw or after every hour of use.
You can use a chainsaw bar and chain oil or a vegetable-based oil that is designed for chainsaw use.

 

Can a worn guide bar cause crooked chainsaw cutting?
Yes, a worn guide bar can cause crooked chainsaw cutting if the guide bar rails are unevenly worn and therefore asymmetrical.
This can cause the chain to rotate at an angle rather than aligned with the bar, creating a vicious circle of wear.

 

Is it necessary to replace the guide bar and sprocket periodically?

 
Yes, it is necessary to replace the guide bar and sprocket periodically to ensure the proper functioning of the chainsaw.
It is recommended to change the sprocket with every second chain replacement and the guide bar with every fourth chain replacement.
