WARNING!
The cutter blades are very sharp!
Always wear gloves when working
around the cutter assembly!
CAUTION!
Operating the hedge trimmer with
worn or improperly adjusted
cutters will reduce cutter perfor-
mance and may also damage this
unit.
Cutter performance of this unit
depends in great measure on cutter
blade clearance. Properly adjusted
blades will oscillate freely yet help
prevent binding of cut material
between blades. Adjust blades as
follows (Figure 26):
1. Loosen all blade locknuts at least
one full turn.
2. Tighten each blade shoulder bolt
firmly, and then loosen the shoul-
der bolts 1/4 to 1/2 turn.
3. Working from the gearcase end,
lock each bolt in place by firmly
tightening its locknut while
preventing the shoulder bolt from
turning.
When shoulder bolt adjustment is
correct, there should be a gap of
0.025–0.050 mm between the cutter
blades and the flat washers, and the
flat washer beneath each bolt head
should turn freely.
