Why Does My Chainsaw Cut Crooked?

If your chainsaw is pulling to the left or right, something is wrong with it.

In online forums and discussion boards, I’ve read a variety of answers for this problem, which is rather prevalent among chainsaw users. Unfortunately, there are a few misguided ideas floating about.

Chainsaws that cut crookedly have one of two causes:

  1. One end of your chain appears to be dull.
  2. Your bar’s edges are crooked.

A number of scenarios exist in which both of these outcomes could occur. We’ll examine each one in turn below before moving on to solutions. ​

1.One end of your chain appears to be dull.

In the vast majority of cases, this is the most likely because of your chainsaw pulling in a single direction. This issue can occur to both novice and experienced chainsaw users. users. Chainsaw users.

A. Causes of an uneven chain

Take a fallen tree and chunk it up. When you reach to the other side, you’ll find a patch of dirt. It’s happened to me before.

When you run into dirt or grind against a rock, your chain will suffer.

Of course, you’re saying, “duh!” now. A rock will be damaged if you hit it with your chain. It should go without saying that.

Yet another factor to consider is that hitting a rock will cause your chain to break on one side more quickly than the other. Consider the possibility that the majority of the harm will be inflicted on one side.

Because of this, if your chainsaw won’t cut straight, consider whether or not you recently ground into something while using it. It’s very certainly a duller chain on one side if you have.

Another possible explanation for an uneven chain is a misaligned sharpness. With a hand file and inexperience, it’s likely that one side of your chain has been ground harsher than the other. As a result, the cut is “crooked.”

To summarize, an unequal chain is most likely the result of:

  1. Hitting a clump of dirt, a rock, or some other hard object.
  2. unevenly sharpening your chain

B. How to fix an uneven chain

If the issue is minimal, you may be able to get it back to normal by filing the chain until it’s smooth.

On both sides of your chain, you’ll have links. Small lines will be painted on each guide and cutter link.

As a comparison tool, the line comes in handy for our needs in this case as well. It serves as a constant reference point for comparing the wear and tear on links on either side.

If the discrepancies are significant, you may want to consider having your chain sharpened by a local saw shop. It is necessary to replace the chain if there are any chips or breaks in it.

2.Your bar’s edges are crooked.

In addition to the chain, your chainsaw bar may be the source of your problem, as I explained earlier.

  1. Factors contributing to an unequal bar

The edges of a chainsaw bar will wear out unevenly over time, it’s a given. The bar and chain’s metal-to-metal friction wears down the metal over time. Your dominant hand, the direction a tree is leaning, and other factors can all influence which side loses material the fastest.

To keep things in balance, experienced chainsaw operators recommend flipping the bar every now and then. If you don’t do this now, you’ll probably end up with a shorter bar in the future (on either side of the chain groove).

  1. How to fix an uneven bar

An uneven bar can be levelled by filing the edges.

To use the file, scratch the bar’s edges as evenly as possible while holding it. Every time you service your chainsaw, be sure to follow these steps.

Pferd’s edge sharpening tool was used to create the image above. One can be found here (disclosure: I receive a commission if you purchase through my link).

When compared to having a saw shop grind the edge off, using a file tool like this is better for your bar and less expensive in the long run.

I hope this blog was beneficial to you and that you now have some answers to your particular chainsaw problem.
