Top 5 Chainsaw Problems and How to Fix Them

Whether you’re trimming trees in your backyard or cutting logs in the forest, a reliable chainsaw makes the job easier. Bonhoeffer chainsaws are built tough, but like any machine, they can sometimes act up. Don’t worry—most chainsaw problems are easy to fix. Here are the top 5 issues and how to solve them.

1. Chainsaw Not Starting

This is the most common problem users face. It’s usually caused by old fuel, a dirty air filter, or a worn spark plug.

Fix it:

• Use fresh fuel with the right mix.

• Clean or replace the air filter.

• Change the spark plug if it looks dirty or damaged.

2. Chain Not Moving

If the engine is running but the chain isn’t spinning, the chain brake might be stuck, or the clutch could be dirty and the chainsaw could be stuck.

Fix it:

• Make sure the chain brake is off.

• Clean out debris around the clutch.

• Replace the clutch if needed.

3. Poor Cutting Performance

A dull or loose chain can make cutting slow and uneven.

Fix it:

• Sharpen the chain regularly.

• Adjust the chain tension—it should be snug but still move.

• Replace the chain if it's too worn out.

4. Chainsaw Stalls While Cutting

If your chainsaw dies under pressure, the carburetor or fuel line could be the problem.

Fix it:

• Clean the carburetor and fuel lines.

• Check and replace the fuel filter if clogged.

• Adjust the carburetor as per the Bonhoeffer manual.

5. Chainsaw Overheating

Overheating can damage your chainsaw if not addressed quickly.

Fix it:

• Clean the cooling fins and air vents.

• Use the correct fuel mix.

• Don’t run the saw too hard in hot weather.
