Why Won’T My Chainsaw Blade Spin

There are a few reasons why your chainsaw blade might not be spinning.

The chain may be too loose:
If the chain is too loose, it will not have enough tension to spin properly. To tighten the chain, follow the instructions in your chainsaw owner’s manual.

The chain may be too tight:
If the chain is too tight, it will bind up and not spin properly. To loosen the chain, follow the instructions in your chainsaw owner’s manual.

The clutch may be engaged:
If the clutch is engaged, the chain will not be able to spin. To disengage the clutch, push the clutch lever forward.

The chainsaw may be out of gas:
If the chainsaw is out of gas, the chain will not be able to spin. To check the gas level, look at the fuel gauge on the chainsaw.

The chainsaw may have a problem with the starter:

Why Won’t My Chainsaw Blade Spin?

There are a few reasons why your chainsaw blade might not be spinning. Here are some of the most common causes:

The chain is too tight:
If the chain is too tight, it will not be able to spin freely. To check the chain tension, follow these steps:
1. Turn off the chainsaw and disconnect the spark plug wire.
2. Loosen the chain tensioner screw.
3. Use a ruler to measure the distance between the top of the chain and the bottom of the bar. The distance should be between 1/8 and 1/4.
4. If the distance is not correct, adjust the chain tensioner screw until it is.

The chain is too loose:
If the chain is too loose, it will not be able to grip the wood properly and will likely come off the bar. To check the chain tension, follow the steps above. The distance between the top of the chain and the bottom of the bar should be between 1/16 and 1/32.

The chain is dull:
A dull chain will not be able to cut through wood effectively and will likely cause the saw to bog down. To check the chain sharpness, run your fingernail along the teeth. If the teeth are smooth, they need to be sharpened.

The bar is dirty:
A dirty bar will cause the chain to bind and will not spin freely. To clean the bar, remove the chain and use a wire brush to clean the bar and the sprocket.

The sprocket is worn:
A worn sprocket will not be able to drive the chain properly and will cause the chain to slow down or stop spinning. 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 clutch is stuck:
The clutch is responsible for engaging and disengaging the chain. If the clutch is stuck, it will not be able to engage the chain and the chain will not spin. To check the clutch, turn on the chainsaw and try to engage the chain. If the chain does not engage, the clutch will need to be repaired or replaced.
