•
Loosen the left cover retaining screw to allow the housing to close.
•
Tighten the right cover retaining screw.
•
With left cover retaining screw ½ turn loose, adjust housing for proper fit.
•
Gently pry the housing open until the blade rotates freely and has enough clearance to
allow the blade to move forward and backward in the housing. Only a slight amount of
movement is necessary.
•
Tighten the cover retaining screws to the recommended torque.
NOTE:
Recommended torque of 30-40 lb-in (3.4-4.5 N-m).
IMPORTANT:
Be sure that the blade is free to move in the housing. If the blade does
not move freely, it may cause the trimmer to overheat.
