WARNING DANGER
Hedge Clipper Blades are very sharp. Wear gloves to protect
hands.
1. Disconnect spark plug wire from spark plug.
2. Slide blades to allow file clearance using slots (A) on bottom of
blades. Do not pry against cutting edges.

avoid damage to adjacent teeth. Maintain 6 mm (.25 in.) radius at
base of each tooth.
