Your chainsaw chain could be too loose.
You need to tighten up your chainsaw chain accordingly and this is very simple. You only have to open the cover that protects the gear and there you can find the screw for adjusting the tension of the chain. In some models, this screw can be found on the left side of the chain bar or in between the chain bar and the engine. Turn clockwise to tighten and counterclockwise to loosen the chain. Also, we have a dedicated blog “How to Tighten Chainsaw Chain” so you’ll learn the tricks for achieving the right chain tension.

Lack of chainsaw bar oil.
The bar oil could have evaporated or you’re not supplying your machine with enough oil regularly. And because you are always running a chainsaw without bar oil, this has caused the bar to shrink or wear out. Make a habit to check your chainsaw bar oil because the lack of oil can easily dull the teeth of the chain and can result in damages to the chain bar.

Worn out chainsaw chain.
You may need a new chainsaw chain when it shows signs of poor cutting performance, smoke comes out from the wood when cutting, and when the chain produces uneven cuts. In these scenarios, the chain may jump off from the chain bar which can be risky for the operator.
