In this guide, we’ll walk you through the steps of diagnosing and resolving a common problem with the Echo 370 chainsaw chain tensioner: the chain won’t stay tight.

Most Common Reasons Of Echo 370 Chainsaw Chain Tensioner Not Working

1. Loose or damaged chain

If the chain is loose, it will not be properly tensioned and will come off the guide bar. If the chain is damaged, it may also not be properly tensioned.

2. Worn-out chain tensioner

The chain tensioner is a spring-loaded device that applies tension to the chain. If the tensioner is worn out, it will not be able to apply enough tension to the chain and the chain will come off the guide bar.

3. Misaligned guide bar

The guide bar is the metal bar that the chain rides on. If the guide bar is misaligned, it will not be able to properly tension the chain and the chain will come off the guide bar.

4. Clogged oil port

The oil port is a small hole in the guide bar that allows oil to be applied to the chain. If the oil port is clogged, the chain will not be properly lubricated and it will wear out faster. This can also lead to the chain coming off the guide bar.

5. Low oil level

The chainsaw needs to have the proper amount of oil in the reservoir in order to properly lubricate the chain. If the oil level is low, the chain will not be properly lubricated and it will wear out faster. This can also lead to the chain coming off the guide bar.
