Most Common Reasons Of Echo 370 Chainsaw Chain Tensioner Not Working

Defective Chain Tensioner

The chain tensioner is a spring-loaded device that applies tension to the chainsaw chain. If the chain tensioner is defective, it may not be able to apply enough tension to the chain, which can cause the chain to come off the guide bar.

Damaged Chain
A damaged chain can also cause the chain tensioner to not work properly. If the chain is too worn, it may not be able to grip the guide bar properly, which can cause the chain to come off.

Incorrect Chain Installation
If the chain is not installed correctly, it may not be able to grip the guide bar properly, which can cause the chain to come off. Make sure that the chain is installed in the correct direction and that it is properly tensioned.

Clogged Oiler Hole
The oiler hole is used to lubricate the chain. If the oiler hole is clogged, the chain will not be properly lubricated, which can cause the chain to wear out faster and eventually come off.

Low Oil Level
The chainsaw must have enough oil in the reservoir to properly lubricate the chain. If the oil level is too low, the chain will not be properly lubricated, which can cause the chain to wear out faster and eventually come off.
