Most Common Reasons Why Stihl Chainsaw Tension Screw Not Working
Defective Tension Screw
The most common reason for a Stihl chainsaw tension screw not working is that the screw is defective. This can happen if the screw is made of a poor quality material, or if it has been damaged. A defective tension screw will not be able to tighten the chain properly, and the chain will be loose.
Damaged Chain Brake
The chain brake is a safety mechanism that prevents the chain from moving when the chainsaw is not in use. If the chain brake is damaged, it can prevent the tension screw from working properly. This is because the chain brake will keep the chain from moving, even when the tension screw is tightened.
Improper Chain Installation
If the chain is not installed properly, it can prevent the tension screw from working properly. This is because the chain must be installed in a specific way in order for the tension screw to be able to tighten it properly. If the chain is not installed correctly, the tension screw will not be able to apply enough pressure to the chain, and the chain will be loose.
Incorrect Chain Tension
The tension screw is used to adjust the tension of the chain. If the chain is too tight, it will be difficult to operate the chainsaw. If the chain is too loose, it will be dangerous to operate the chainsaw. The tension screw must be adjusted so that the chain is neither too tight nor too loose.
Dirty or Damaged Tension Screw
If the tension screw is dirty or damaged, it can prevent the tension screw from working properly. This is because the dirt or damage can prevent the screw from turning properly. To fix this problem, the tension screw must be cleaned and/or replaced.
