Possible Causes

There are a number of possible causes for a Dewalt chainsaw to stop working. Some of the most common causes include:

A dull chain:

If the chain on your chainsaw is dull, it will not be able to cut through wood properly. This can cause the chain to overheat and eventually break.

A dirty chain:

A dirty chain can also cause problems with your chainsaw. Dirt and debris can build up on the chain and make it difficult to move. This can also cause the chain to overheat and break.

The air filter on your chainsaw helps to keep the engine clean. If the air filter is clogged, it can restrict airflow to the engine. This can cause the engine to overheat and eventually stop working.

A bad carburetor:

The carburetor on your chainsaw helps to mix the fuel and air. If the carburetor is not working properly, it can cause the engine to run poorly and eventually stop working.
