1
Disengage the brake by pushing the kickback
guard backwards. Unscrew the guide bar bolts and
remove the clutch cover, chain and guide bar.

Grip the clutch cover carefully in a vice. Release
the brake spring by using the kickback guard from
the saw as a tool. Engage it with the brake mecha-
nism and turn anticlockwise to activate the brake.
Remove the screws and carefully remove the cover
from the chain brake spring.

Place one hand over the spring and insert a small
screwdriver between the bottom end of the spring
and the clutch cover. Carefully prise the spring
upwards so that it slides onto the screwdriver shaft.
