Most Common Reasons Of Stihl Chainsaw Chain Brake Not Working

Most Common Reasons Of Stihl Chainsaw Chain Brake Not Working

1. Loose or damaged chain brake cable

The chain brake cable is a critical component of the chainsaw’s safety system. It connects the chain brake lever to the brake mechanism, and when the lever is pulled, it engages the brake and stops the chain from moving. If the cable is loose or damaged, it will not be able to properly engage the brake, and the chain could continue to move even when the lever is pulled.

2. Faulty chain brake lever

The chain brake lever is another critical component of the chainsaw’s safety system. It is the user’s interface for engaging and disengaging the chain brake. If the lever is faulty, it may not be able to properly engage the brake, or it may engage the brake when it is not supposed to.

3. Clogged or damaged chain brake mechanism

The chain brake mechanism is a mechanical device that engages the brake when the chain brake lever is pulled. If the mechanism is clogged or damaged, it will not be able to properly engage the brake, and the chain could continue to move even when the lever is pulled.

4. Low chain oil level

The chain brake is lubricated by the chain oil. If the chain oil level is low, the brake will not be able to properly engage, and the chain could continue to move even when the lever is pulled.

5. Misalignment of the chain brake

The chain brake must be properly aligned with the chain in order to function properly. If the brake is misaligned, it will not be able to properly engage the chain, and the chain could continue to move even when the lever is pulled.
