Why Your Chainsaw Won’t Cut (And How to Fix It)

Your chainsaw won’t cut for a number of reasons. Here are some of the most common causes and how to fix them:

Dull chain:

The most common reason for a chainsaw not cutting is a dull chain. To sharpen the chain, you will need a chainsaw file. Follow the manufacturer’s instructions for sharpening your specific chainsaw.

Low chain tension:

If the chain is too loose, it will not be able to cut effectively. To tighten the chain, use the chain tensioner on your chainsaw.

Clogged bar oil hole:

If the bar oil hole is clogged, the chain will not be lubricated properly and will quickly become dull. To clean the bar oil hole, use a small brush or needle to remove any debris.

Dirty or damaged bar:

A dirty or damaged bar can also cause the chain to not cut properly. To clean the bar, use a soft cloth or brush to remove any dirt or debris. If the bar is damaged, it will need to be replaced.

Incorrect chain type:

Make sure you are using the correct chain for your chainsaw. The chain must be the correct pitch, width, and gauge for your saw.

By following these tips, you can quickly and easily troubleshoot why your chainsaw won’t cut and get it back up and running in no time.

Why Won’t My Chainsaw Cut?

1. Dull Chain

The most common reason why a chainsaw won’t cut is a dull chain. When the chain is dull, it can’t grip the wood properly and will just slide over it. To check if your chain is dull, run your finger along the teeth. If they are smooth, the chain is dull and needs to be sharpened.

2. Misaligned Chain

Another common reason why a chainsaw won’t cut is a misaligned chain. This can happen if the chain is installed incorrectly or if it has become loose. To check if your chain is aligned, look at the guide bar. The chain should be running parallel to the bar. If it is not, you will need to realign the chain.

3. Clogged Bar Oiler

A clogged bar oiler can also prevent a chainsaw from cutting properly. The bar oiler lubricates the chain and helps to keep it cool. If the oiler is clogged, the chain will not be lubricated properly and will quickly become dull. To check if your bar oiler is clogged, look at the oil hole on the bar. If there is no oil coming out, the oiler is clogged and needs to be cleaned.

4. Low Chain Tension

If the chain tension is too low, the chain will not be able to grip the wood properly and will just jump off the bar. To check the chain tension, hold the chainsaw with the chain off the ground. The chain should be tight enough to not sag, but not so tight that it is difficult to turn the handle.

5. Bad Spark Plug

If your chainsaw is not starting, or if it is starting but not running smoothly, it could be a problem with the spark plug. To check the spark plug, remove it from the chainsaw and look at the electrode. If the electrode is black or fouled, the spark plug needs to be replaced.

6. Carburetor Problems

If your chainsaw is running but not cutting properly, it could be a problem with the carburetor. The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is not adjusted properly, the chainsaw will not run smoothly and will not cut properly.

7. Engine Problems

If your chainsaw is not running at all, it could be a problem with the engine. The engine could be seized, the piston could be damaged, or the valves could be out of adjustment. If you suspect that there is a problem with the engine, it is best to take the chainsaw to a qualified technician for repairs.

Troubleshooting Tips

If you are having trouble troubleshooting your chainsaw, here are a few tips:

Start by checking the basics. Make sure that the chain is sharp, aligned, and properly tensioned. Check the oil level and make sure that the bar oiler is working properly.
If the chainsaw is still not cutting properly, try cleaning the spark plug. If the spark plug is fouled, it could be causing the chainsaw to run poorly.
If the chainsaw is still not running properly, take it to a qualified technician for repairs.
