Causes of a Chainsaw Chain Falling Off

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

Improper tensioning:

If the chain is too loose, it will be more likely to fall off. To check the tension, hold the chainsaw with the chain off the ground and pull on the chain with your hand. There should be about 1/8-inch of play between the chain and the bar. If there is more than that, you need to tighten the chain.

Damaged or worn sprockets:

The sprockets are the gears that drive the chain around the bar. If they are damaged or worn, they can cause the chain to slip and fall off.

Damaged or worn chain links:

If the chain links are damaged or worn, they can also cause the chain to fall off.

Clogged or dirty bar oiler:

The bar oiler lubricates the bar and chain, which helps to prevent them from overheating and wearing out. If the bar oiler is clogged or dirty, it can cause the chain to overheat and become loose, which can lead to it falling off.

Incorrect bar alignment:

The bar on a chainsaw should be aligned parallel to the ground. If the bar is not aligned properly, it can cause the chain to bind and fall off.

Once you have identified the cause of the problem, you can take steps to fix it. Here are some tips:
