Why Stihl Chainsaw Tension Screw Not Working
Loose Pulley
The most common reason for a chainsaw tension screw not working is a loose pulley. This can happen if the screw is not tightened enough or if the pulley has become worn. To fix this, you will need to tighten the screw or replace the pulley.
Damaged Chain
Another common cause of a chainsaw tension screw not working is a damaged chain. If the chain is damaged, it can cause the screw to become stuck or to not tighten properly. To fix this, you will need to replace the chain.
Clogged Oiler Hole
A clogged oiler hole can also prevent the chainsaw tension screw from working properly. This is because the oiler hole helps to lubricate the screw and keep it from sticking. To fix this, you will need to clean the oiler hole.
Seized Screw
In some cases, the chainsaw tension screw can become seized. This can happen if the screw is not lubricated properly or if it is exposed to dirt and debris. To fix this, you will need to remove the screw and clean it thoroughly. If the screw is still seized, you may need to replace it.
Damaged Chainsaw
In rare cases, a chainsaw tension screw may not work properly due to damage to the chainsaw itself. This can happen if the chainsaw is dropped or if it is struck by something. To fix this, you will need to repair or replace the chainsaw.
