D. Blade Adjustment and Comb
Orientation
The care and adjustment of the blades is very important to the
efficient operation of the trimmer and especially to the long life of
the engine.
1. Place 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
protective 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 correct adjusted
position.
4. Repeat Step 3 on the screws in turn until all are correctly
adjusted.
5. Orientation of the comb is very important. The comb has
staggered teeth for better cutting performance. Correct comb
orientation is shown below.
NOTE: Correct blade adjustment can only be achieved on clean,
oiled blades.
