2- Relief the tension of the chain

After removing the side plate, the old chain is ready to remove. At this time, we have to pull the nose of the chainsaw bar as it is away from the chainsaw. The tension of the chain will release. Remove the old chainsaw from the guide bar.  

At this time, hand gloves protect us from hurting our hands or fingers.

3- Loosening the tensioning screw:

The position of this screw is inside of the guide. We need to lose it. After this, we install a new chain.

4- Thread the new chain and align the guide bar
