Why Does My Chainsaw Keep Shutting Off?

Your chainsaw keeps shutting off because the chain is too loose, the spark plug is fouled, the carburetor is out of adjustment, or the air filter is dirty. Let’s troubleshoot each of these possible causes one by one.

Why Does My Chainsaw Keep Shutting Off

There are a few reasons why your chainsaw might keep shutting off.

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 the flow of air to the chainsaw’s 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 the chainsaw to misfire and shut down. Clean or replace the spark plug as needed.

Bad carburetor:
A bad carburetor can cause the chainsaw to run lean (not enough fuel) or rich (too much fuel). This can lead to the chainsaw stalling or shutting down. Have the carburetor serviced or repaired as needed.

Why Does My Chainsaw Keep Shutting Off?

There are a few possible reasons why your chainsaw might keep shutting off.

The chain is too tight:
If the chain is too tight, it will put too much strain on the engine and cause it to overheat. This can lead to the chainsaw shutting off. To check if the chain is too tight, try to turn the chain by hand. If it is difficult to turn, the chain is too tight. To loosen the chain, use the chain tensioner to adjust the tension.

The chain is too loose:
If the chain is too loose, it will not be able to grip the wood properly and will cause the chainsaw to stall. To check if the chain is too loose, try to pull the chain away from the bar. If the chain is able to move more than 1/2 inch, the chain is too loose. To tighten the chain, use the chain tensioner to adjust the tension.

The carburetor is dirty:
If the carburetor is dirty, it will not be able to deliver the correct amount of fuel to the engine. This can cause the chainsaw to run erratically and eventually shut off. To clean the carburetor, you will need to remove it from the chainsaw and disassemble it. Once the carburetor is disassembled, you can clean it with a carburetor cleaner.

The spark plug is fouled:
If the spark plug is fouled, it will not be able to produce a spark. This will prevent the engine from starting or running properly. To check if the spark plug is fouled, remove it from the engine and inspect it. If the spark plug is black and sooty, it is fouled. To clean the spark plug, you can use a spark plug cleaner.

The air filter is dirty:
If the air filter is dirty, it will restrict the airflow to the engine. This can cause the engine to run hot and eventually shut off. To check if the air filter is dirty, remove it from the engine and inspect it. If the air filter is clogged with dirt or dust, it needs to be replaced.

How to Fix a Chainsaw That Keeps Shutting Off

Once you have identified the cause of the problem, you can fix the chainsaw. Here are the steps to fix a chainsaw that keeps shutting off:

1. Adjust the chain tension:
If the chain is too tight or too loose, adjust the chain tension until it is properly tensioned.

2. Clean the carburetor:
If the carburetor is dirty, remove it from the chainsaw and clean it with a carburetor cleaner.3. Replace the spark plug:
If the spark plug is fouled, replace it with a new spark plug.

4. Clean the air filter:
If the air filter is dirty, remove it from the engine and clean it or replace it with a new air filter.

Preventing Chainsaw Problems

A properly tensioned chain will not put too much strain on the engine and will help to prevent the chainsaw from overheating.

Keep the carburetor clean:
A clean carburetor will help the chainsaw run properly and will prevent it from stalling.

Replace the spark plug regularly:
A fouled spark plug can prevent the engine from starting or running properly.
