Why Does My Chainsaw Keep Cutting Out?

Why Does My Chainsaw Keep Cutting Out

There are a few reasons why your chainsaw might keep cutting out.

Low oil level:

Make sure the oil level is correct. If the oil level is too low, the chainsaw will not be able to lubricate itself properly and will eventually overheat and cut out.

Dirty air filter:

A dirty air filter can restrict airflow to the engine, causing it to overheat and cut out. Clean the air filter regularly to prevent this problem.

Clogged spark plug:

A clogged spark plug can prevent the engine from firing properly, causing it to cut out. Clean or replace the spark plug as needed.

Bad fuel:

Using old or bad fuel can cause the engine to malfunction and cut out. Make sure you are using fresh, clean fuel.

Engine problems:

If the engine is damaged or worn out, it may not be able to run properly and will eventually cut out. Have the engine inspected by a qualified technician to determine if it is the source of the problem.

The chain is too tight:
If the chain is too tight, it will put too much strain on the engine and cause it to stall. To check the chain tension, release the chain brake and let the chain hang freely. The chain should be able to move up and down about 1/2 inch (1.27 cm). If it doesn’t, tighten the chain until it does.

If the chain is too loose, it will jump off the guide bar and cause the chainsaw to stall. To check the chain tension, release the chain brake and let the chain hang freely. The chain should be snug against the guide bar, but it shouldn’t be so tight that it’s difficult to move. If the chain is too loose, tighten it until it’s snug.

The fuel filter is clogged:
If the fuel filter is clogged, it can restrict the flow of fuel to the engine and cause the chainsaw to stall. To check the fuel filter, remove it from the chainsaw and inspect it. The filter should be clean and free of debris. If the fuel filter is clogged, replace it with a new one.
