Setting/Replacing
Knives
Planer knives are extremely sharp and can
quickly cause a serious injury to your hands
or fingers. Always wear heavy leather gloves
when handling these knives to reduce the
risk of cutting injuries.
setting the height of the knives correctly is cru-
cial to the proper operation of your planer and
is very important in keeping the knives sharp. if
one knife protrudes higher than the others, it will
do the majority of the work, dull much faster, and
produce poor cutting results.
the knife gauge that is included with the Model
g0453/g0454 is designed to set the knives
0.059" higher than the cutterhead surface.
Note: If you need to replace or sharpen a knife,
you can remove the knife from the cutterhead dur-
ing
Step 4 of the following procedure. Thoroughly
clean out any debris from the knife slots before
replacing the knives.
Replacement knives are available through Grizzly
(refer to
Page 28 for options).
