The cutterhead knives on the G8794 planer are
extremely sharp. Merely brushing your finger
along the edge can result in a severe cut. Take
extreme caution when doing any adjustments
involving the cutterhead knives. Wear thick
gloves anytime it is necessary to manually
rotate the cutterhead assembly.

head. See Figure 10.

NOTICE
Never run the planer with only one knife
installed in the cutterhead. This will cause a
severe imbalance condition at the high speed
at which the cutterhead rotates. Always install
both knives and make certain they are tightly
secured. When resharpening, always have
both knives sharpened as a set.
Make sure the G8794 is unplugged or discon-
nected from the power source and moving
parts have come to a complete stop before
investigating any problems or performing any
maintenance or adjustments. Serious person-
al injury may occur.

To install and adjust the knives:
1. Make sure the two springs in the knife
groove are in position. If the knife locking
bar was removed, make certain it is rein-

turn the tightening bolts counterclockwise

until they begin to contact the side of the
groove. Then tighten further, starting with
the bolts at the center and working toward
the outer ones. Once they are tight enough
to hold the knife in position, remove the
gauge.
5. Do a final tightening of each bolt. Recheck
with the setting gauge to make certain the
knife did not move. The knife tip should be
just touching the top of the arc of the gauge
as shown in Figure 10.
