If your Husqvarna chainsaw is not working as it should, this guide can help you troubleshoot and solve the problem. Here, we have listed the most common problems and the fixes to apply.
Husqvarna Chainsaw Troubleshooting Guide
1. Husqvarna Chainsaw Fuel Problems
One of the most common issues with chainsaws is related to fuel. If your chainsaw is not starting or is stalling, it may be a fuel problem.
- Fuel mix is incorrect: The fuel mix used in chainsaws must be a mixture of gasoline and two-stroke oil in the right ratio. If the mixture is not correct, the chainsaw will not start or will run poorly.
- Fuel is stale or contaminated: Old or contaminated fuel can cause problems starting and running the chainsaw. It is best to drain the fuel tank and add fresh fuel before attempting to start the chainsaw.
- Fuel filter is clogged: The fuel filter may become clogged, preventing fuel from reaching the carburetor. Check the fuel filter and replace it if it is clogged.
- Fuel line is kinked or clogged: In certain cases, the problem would be the fuel line. This could become kinked or clogged, and would have to be checked and cleaned or replaced.
2. Husqvarna Chainsaw Not Starting
If your chainsaw is not starting, there are several possible causes.
- Spark plug is fouled: A fouled spark plug is the most common reason for starting issues. Check the spark plug and replace it if it is fouled.
- Air filter is dirty: A dirty air filter could also be a problem. Clean or replace the air filter.
- Choke is not set properly: The choke must be set in the correct position to start the chainsaw. Refer to the owner’s manual for the correct choke setting.
- Carburetor is clogged: A clogged carburetor is not usually common but can also prevent the chainsaw from starting. Clean or rebuild the carburetor as necessary.
3. Husqvarna Chainsaw Cutting Problems
If your chainsaw is running but is not cutting properly, there are several reasons to this.
- Chain is dull: A dull chain will not cut properly. Sharpen the chain or replace it if necessary.
- Chain is loose: A loose chain can cause cutting problems. Tighten the chain according to the owner’s manual instructions.
- Chain tension is incorrect: Incorrect chain tension can also cause cutting problems. Adjust the chain tension as necessary.
- Bar is bent: A bent bar would hinder the chainsaw’s ability to cut properly. Replace the bar if it is bent.
4. Husqvarna Chainsaw Vibration Problems

- Recoil spring is broken: If the recoil spring is broken, the starter rope will not rewind properly. Replace the recoil spring if it is broken.
8. Husqvarna Chainsaw Chain Oiler Problems
- Oiler is clogged: If the chain oiler is clogged, it can prevent oil from reaching the chain, causing excessive wear and damage. Clean or replace the chain oiler as necessary.
- Oil level is too low: If the oil level is too low, the chain will not receive enough lubrication, which would lead to excessive wear and damage. Fill the oil tank to the correct level.
