Why Your Chainsaw Isn’t Cutting and How to Fix It

Your chainsaw isn’t cutting for a few reasons. It could be dull, the chain is too loose, or the bar is bent.

To fix a dull chain, sharpen it with a chainsaw file. To tighten the chain, loosen the bar nuts and slide the chain up until it’s snug against the bar. To fix a bent bar, straighten it with a bar bender.

Here’s a quick guide to fixing a chainsaw that isn’t cutting:

1. Check the chain for sharpness:
If the chain is dull, it won’t be able to cut through wood. Sharpen the chain with a chainsaw file.

2. Check the chain tension:
If the chain is too loose, it will jump off the bar and won’t be able to cut properly. Tighten the chain by loosening the bar nuts and sliding the chain up until it’s snug against the bar.3. Check the bar for bends:
If the bar is bent, it will cause the chain to skip and won’t be able to cut properly. Straighten the bar with a bar bender.

If you’ve checked all of these things and your chainsaw still isn’t cutting, you may need to take it to a professional for repair.

Possible Causes

There are a number of possible reasons why your chainsaw might not be cutting properly. Here are some of the most common:

Dull chain:

The most common reason for a chainsaw not cutting is a dull chain. If the chain is dull, it will not be able to penetrate the wood properly and will cause the saw to bog down. To check if the chain is dull, run your finger along the teeth. If they are rounded and smooth, it’s time for a sharpening.

Low chain tension:

If the chain is too loose, it will not be able to grip the wood properly and will cause the saw to jump. To check the chain tension, hold the chainsaw with the blade pointing up. The chain should be tight enough that you can only move it about 1/8 of an inch up and down. If it’s looser than that, tighten it using the chain tensioner.

Clogged bar oiler:

If the bar oiler is clogged, the chain will not be lubricated properly and will quickly become dull. To check the bar oiler, look for a small hole in the bar near the front of the saw. If there is no oil coming out of the hole, the oiler is clogged and will need to be cleaned.

Dirty air filter:

A dirty air filter can restrict airflow to the engine, causing it to run poorly and not produce enough power to drive the chain. To check the air filter, remove it from the saw and inspect it for dirt and debris. If it’s dirty, clean it according to the manufacturer’s instructions.

Spark plug problems:

If the spark plug is fouled or damaged, it will not be able to produce a spark, which will prevent the engine from starting. To check the spark plug, remove it from the engine and inspect it for damage. If it’s fouled, clean it or replace it.

Troubleshooting Tips

If your chainsaw is not cutting properly, here are a few troubleshooting tips:

Check the chain tension first:
This is the most common cause of a chainsaw not cutting.
