Your Chainsaw Chain Won’t Move Here’s Why and How to Fix It

Your chainsaw is one of the most important tools in your arsenal, but it can be frustrating when it doesn’t work properly. If your chainsaw chain won’t move, there are a few possible causes. In this blog post, we’ll discuss the most common reasons why your chainsaw chain might be stuck and how to fix it.

Why Won’T My Chain Move On My Chainsaw

There are a few reasons why the chain on your chainsaw might not be moving.

The chain is too tight:
If the chain is too tight, it will bind against the bar and not move. To check the chain tension, use a chainsaw chain tension gauge. The chain should have about 1/8 of play between the chain and the bar.

The chain is too loose:
If the chain is too loose, it will come off the bar and not move. To check the chain tension, use a chainsaw chain tension gauge. The chain should have about 1/8 of play between the chain and the bar.

The chain is damaged:
If the chain is damaged, it will not move properly. Check the chain for broken or missing links, and replace the chain if necessary.

The bar is damaged:
If the bar is damaged, it will not be able to hold the chain properly. Check the bar for cracks or other damage, and replace the bar if necessary.

The chainsaw is not getting enough oil:
If the chainsaw is not getting enough oil, the chain will become dry and will not move properly. Make sure the chainsaw is properly lubricated, and add oil to the chain oil reservoir as needed.

Possible Causes

There are a few possible reasons why your chainsaw chain might not be moving. Here are some of the most common:

The chain is too tight:
If the chain is too tight, it will not be able to move freely around the bar. To check the chain tension, use a chain tension gauge. If the chain is too tight, loosen the tensioner screw until the gauge indicates the proper tension.

The chain is too loose:
If the chain is too loose, it will jump off the bar. To check the chain tension, use a chain tension gauge. If the chain is too loose, tighten the tensioner screw until the gauge indicates the proper tension.

The bar is bent:
If the bar is bent, the chain will not be able to move smoothly around it. To check for a bent bar, sight down the bar from the front and back. If the bar is not straight, it will need to be straightened or replaced.

The sprocket is worn out:
The sprocket is the gear that drives the chain. If the sprocket is worn out, it will not be able to grip the chain properly and the chain will not move. To check the sprocket, look for wear marks on the teeth. If the teeth are worn down, the sprocket will need to be replaced.

The chain oiler is not working:
The chain oiler lubricates the chain and helps to keep it moving smoothly. If the chain oiler is not working, the chain will become dry and will not move as easily. To check the chain oiler, look for oil dripping from the oil hole in the bar. If no oil is dripping, the oiler may be clogged or broken and will need to be repaired or replaced.

How to Fix the Problem

Once you have identified the cause of the problem, you can fix it by following these steps:

If the chain is too tight, loosen the tensioner screw until the chain is properly tensioned:

If the chain is too loose, tighten the tensioner screw until the chain is properly tensioned:

If the bar is bent, straighten or replace it:

If the sprocket is worn out, replace it:

If the chain oiler is not working, clean or replace it:

After you have fixed the problem, test the chainsaw to make sure that the chain is moving freely. If the chain is still not moving, you may need to take the chainsaw to a qualified repair shop.

Preventative Maintenance

The best way to prevent problems with your chainsaw chain is to perform regular preventative maintenance. Here are some tips:

Tighten the chain regularly:
The chain should be checked and tightened every time you use the chainsaw.

Lubricate the chain regularly:
The chain should be lubricated every time you use the chainsaw.

Inspect the bar and sprocket regularly:
The bar and sprocket should be inspected for wear and damage every time you use the chainsaw.

By following these tips, you can help to keep your chainsaw chain in good working order and prevent problems from occurring.
