What are the most common reasons a chainsaw won’t cut?


A chainsaw is a powerful tool that many people use to cut down trees. Chainsaws are not perfect, and there are some instances where the chainsaw will not cut through whatever you are trying to cut. There are several reasons why this may happen, so let’s take a look at them!

1.      Chain tension may not be proper

The chain may not be tensioned appropriately, and this could cause the chainsaw to stop cutting. The teeth of a saw should line up perfectly with the angle on the bar, so you must check your blade alignment before trying to cut through something. If you notice any drooping or curving in either direction when looking at the blade, this is an indicator that the tension needs to be adjusted.

2.      The chain brake is broken or stuck

If the chain brake is stuck or not working, this could be another reason why your chainsaw may not cut. The chain brake allows you to turn off the saw whenever it gets too difficult for you to handle. By pulling on a small string that runs parallel with the bar of the chainsaw will cause metal pieces inside of the chainsaw to stop the chain from moving. If this brake is not working, it may be necessary for you to take your chainsaw into a service center or purchase an entirely new one if there are no replacement parts available on the market today.

3.      Guide bar may be worn and bent

If the guide bar is bent or worn, this can also cause a chainsaw not to cut correctly. The chain moves around the guide very quickly, and it needs something sturdy for support. If your guide bar does not have metal pieces running along either side called spacers, you may need to replace both of these and the bar. If the spacer is bent or broken, it can cause your chain to go in different directions and not cut correctly.

4.      Improper tension of spring or broken clutch spring

If the spring tension or clutch springs are not balanced correctly, this can also cause a chainsaw to stop cutting. These two parts work together and help keep your saw in control while it is running. If these pieces are broken, you may need to get them replaced before attempting any maintenance on a chainsaw again. This will keep you safe while continuing to use your chainsaw, and it could prolong the life of your equipment.
