Causes of a Loose Chainsaw Chain

There are a few different reasons why the chain on your chainsaw might keep coming loose. Here are some of the most common causes:

Improper tensioning:

If the chain is not properly tensioned, it will be more likely to come loose. To check the tension, hold the chainsaw with the chain off the ground. The chain should be tight enough that you can lift it up about 1 inch (2.5 cm) with your fingers, but not so tight that it is difficult to move.

Worn or damaged chain:

A worn or damaged chain can also cause it to come loose. If the chain is too worn, the teeth will not be able to grip the wood properly, and the chain will be more likely to slip. If the chain is damaged, it may have broken links or other problems that will prevent it from staying on the sprockets.

Dirty or clogged sprockets:

If the sprockets on your chainsaw are dirty or clogged with sawdust, the chain will not be able to grip them properly and will be more likely to come loose. Make sure to clean the sprockets regularly to prevent this problem.

Incorrect bar alignment:

If the bar on your chainsaw is not aligned properly, the chain will not be able to track properly and will be more likely to come loose. To check the alignment, hold the chainsaw with the chain off the ground. The bar should be parallel to the ground and the chain should be running straight up and down the bar.
