Why Does My Chainsaw Keep Shutting Off?

There are a few reasons why your chainsaw might keep shutting off. Here are the most common:

Low oil level:

Make sure the oil level is between the “full” and “add” marks on the chainsaw’s oil reservoir.

Clogged air filter:

A clogged air filter can restrict airflow to the engine, causing it to overheat and shut down. Clean or replace the air filter as needed.

Dirty spark plug:

A dirty spark plug can cause misfires, which can also lead to the engine overheating and shutting down. Clean or replace the spark plug as needed.

Worn chain:

A worn chain can cause the chainsaw to work harder, which can lead to overheating and shutdown. Replace the chain as needed.

Bad carburetor:

A bad carburetor can cause the chainsaw to run too rich or too lean, which can both lead to overheating and shutdown. Have the carburetor repaired or replaced as needed.

If you’ve checked all of these things and your chainsaw is still shutting off, it’s time to take it to a qualified chainsaw repair technician.

Possible Causes

There are a number of possible causes for a chainsaw to keep shutting off. Here are some of the most common:

Low oil level:
If the oil level in your chainsaw is too low, the engine will not be able to lubricate itself properly and will eventually overheat and shut down. To check the oil level, remove the oil cap and look at the dipstick. The oil level should be between the full and add marks. If the oil level is low, add oil to the crankcase until it reaches the full mark.

Dirty air filter:
A dirty air filter can restrict airflow to the engine, causing it to overheat and shut down. To clean the air filter, remove it from the chainsaw and rinse it with warm, soapy water. Allow the air filter to dry completely before reinstalling it.

Clogged carburetor:
A clogged carburetor can prevent the engine from getting the proper amount of fuel, causing it to run lean and eventually shut down. To clean the carburetor, remove it from the chainsaw and follow the manufacturer’s instructions for cleaning and rebuilding the carburetor.

Spark plug problems:
A faulty spark plug can prevent the engine from firing, causing it to shut down. To check the spark plug, remove it from the engine and inspect it for damage. If the spark plug is damaged, replace it with a new one.

Engine problems:
If the engine itself is damaged, it may not be able to run properly and will eventually shut down. To determine if the engine is damaged, have it inspected by a qualified technician.
