VIII. PARTS EXPLOSIONS
GEAR HOUSING ASSEMBLY
The care and adjustment of the blades is most
important to the efficient operation of the
trimmer and especially to the long life of the
engine.
1. Place the trimmer in vise clamping on the
frame bar. Be careful! Blades are sharp!
2. Using a 7/16” wrench, loosen all blade
locknuts and unscrew the large head screws
by two turns.
3. Starting with the screw nearest the gear
housing, tighten the screw until the blade
guard of the Single Edge trimmer or the pro-
tective comb of the Double Edge trimmer can
just be moved with finger pressure and a
.0015” (1 1/2 thou.) feeler blade just slips
under the blade guard or comb. Tighten the
locknuts while holding the screw stationary in
its correctly adjusted position.
4. Repeat Step 3 on the screws in turn until
all are correctly adjusted.
