⚠️ There is a high probability that the chain gets damaged after being thrown out of the guide bar. Please make absolutely sure that refit is possible or replace the chain with a new one that properly fits your guide bar.
If the chain gets thrown as soon as you start the saw, it is very probable that you are not using the correct chain type/size or rim/drive sprocket.
If the chain gets thrown during use, then it probably needs to be clean and adjusted for tension.
Read the steps and follow the links below for further instructions.
1
First of all please make absolutely sure the chain is the correct type/size for your guide bar and rim/drive sprocket.
