Your chainsaw is getting stuck because the chain is too tight. When the chain is too tight, it puts more strain on the engine and can cause it to overheat. It can also cause the chain to skip and jump, which can be dangerous. To fix this problem, you need to loosen the chain until it can move freely without binding.

Why Does My Chainsaw Keep Getting Stuck

There are a few reasons why your chainsaw might be getting stuck.

The chain is too tight:
If the chain is too tight, it will bind up and not be able to move freely.

The chain is dull:
A dull chain will not be able to cut through wood as easily and will cause the saw to bog down.

The bar is dirty:
A dirty bar will cause the chain to bind up and not be able to move freely.

The sprocket is worn out:
A worn-out sprocket will not be able to grip the chain properly and will cause it to slip.

The chain oil is low:
If the chain oil is low, the chain will not be lubricated properly and will cause it to heat up and bind up.

Possible Causes

There are a few possible reasons why your chainsaw might be getting stuck. Here are some of the most common:

The chain is too tight:
If the chain is too tight, it can bind up and cause the chainsaw to stall. To check the chain tension, release the bar-lock lever and lift the chain up. The chain should be able to move up and down about 1/2 inch (1.3 cm) freely. If it doesn’t, loosen the chain tensioner until it does.

The chain is dull:
A dull chain will also cause the chainsaw to stall. To check the chain sharpness, run your fingernail across the teeth. If the teeth are rounded over, it’s time to sharpen the chain.

The bar is dirty:
A dirty bar can also cause the chain to bind up. To clean the bar, remove the chain and use a wire brush to scrub off any dirt or debris.

The sprocket is worn:
The sprocket is the gear that drives the chain. If the sprocket is worn, it can cause the chain to slip and bind up. To check the sprocket, look for wear marks on the teeth. If the teeth are worn down, replace the sprocket.

The chain oiler is not working properly:
The chain oiler lubricates the chain and helps to prevent it from binding up. If the chain oiler is not working properly, the chain will not be lubricated properly and it will be more likely to bind up. To check the chain oiler, make sure that the oil reservoir is full and that the oil is flowing freely.

Troubleshooting Tips

If your chainsaw is still getting stuck after you’ve checked all of the possible causes, here are a few troubleshooting tips:

Try adjusting the chain tension. If the chain is too tight, loosen it until it moves freely. If the chain is too loose, tighten it until it just snug against the bar.
Sharpen the chain. A dull chain will cause the chainsaw to stall. To sharpen the chain, use a chainsaw file to remove any burrs or dull spots.
Clean the bar. A dirty bar can cause the chain to bind up. To clean the bar, remove the chain and use a wire brush to scrub off any dirt or debris.
Replace the sprocket. If the sprocket is worn, replace it with a new one.
Check the chain oiler. Make sure that the oil reservoir is full and that the oil is flowing freely.

If you’ve tried all of these troubleshooting tips and your chainsaw is still getting stuck, it’s time to take it to a professional for repairs.

The best way to prevent your chainsaw from getting stuck is to perform regular maintenance. Here are a few things you can do to keep your chainsaw running smoothly:

Tighten the chain regularly:
The chain should be tightened to the manufacturer’s specifications.

Sharpen the chain regularly:
A dull chain will cause the chainsaw to stall.

There are a few reasons why your chainsaw might be getting stuck. Here are some of the most common causes:

The chain is too tight: If the chain is too tight, it will be difficult to turn the chainsaw and the chain will be more likely to get stuck. To check if the chain is too tight, try to turn the chainsaw by hand. If the chain is difficult to turn, loosen the chain tensioner until the chain can turn freely.

The chain is too loose: If the chain is too loose, it will be more likely to come off the guide bar. To check if the chain is too loose, try to lift the chain off the guide bar. If the chain can be lifted more than 1/2 inch, tighten the chain tensioner until the chain is snug against the guide bar.

The guide bar is dull: A dull guide bar will make it difficult to cut through wood and the chain will be more likely to get stuck. To check if the guide bar is dull, try to shave a piece of wood. If the guide bar does not make a clean cut, it needs to be sharpened.

The chain is old or damaged: An old or damaged chain will be more likely to get stuck. To check if the chain is old or damaged, look for any cracks or broken links. If the chain is damaged, it needs to be replaced.

The chainsaw is not properly maintained: If the chainsaw is not properly maintained, it will be more likely to develop problems that can cause the chain to get stuck. To properly maintain your chainsaw, make sure to:

Clean the chainsaw after each use: This will help to prevent the build-up of sawdust and debris, which can clog the chain and cause it to get stuck.

Oil the chain regularly: This will help to keep the chain lubricated and prevent it from overheating.

Sharpen the chain regularly: A sharp chain will make it easier to cut through wood and will reduce the risk of the chain getting stuck.

Inspect the chainsaw regularly for any problems: This will help to identify any potential problems before they cause the chain to get stuck.
