1. Remove the guide bar side panel.

The side plate on most chainsaws will most likely be held on by two nuts.

Using a scwrench or wrench, unscrew the nuts and remove the plate to access the chain.

If your chainsaw's brake is attached to its side plate, make sure to unlock the brake before removing sprocket the plate. Removing the side plate with the brake in the locked position can make it difficult or impossible to reinstall.
