Setting Feed Rate; Adjusting/Replacing Knives - Grizzly G0815 Owner's Manual

Setting Feed Rate

The infeed and outfeed rollers move the workpiece
through the planer while keeping it flat and provid-
ing a consistent rate of movement. The speed
that these rollers move the workpiece through the
planer is the feed rate.
Generally, low feed rates are used for dimension-
ing passes, while higher feed rates are used for
finishing passes.
Figure 20 illustrates the three different positions
of the feed rate control knob:
• Push knob in to use high feed rate of 30 FPM.
• Pull the knob out to use the low feed rate of
16 FPM.
• Move knob to center position to place gear-
box in neutral.

NOTICE
Only change the feed rate when the planer
is running, but DO NOT attempt to change
the feed rate during any cutting operations
or damage to the gearbox will result.

Adjusting/Replacing
Knives
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
Cutterhead knives are extremely sharp.
Accidental contact with knives can result in
severe cuts. Take great caution whenever
working with or around cutterhead knives.
Wear heavy leather gloves to reduce risk of
severe cuts.
To maintain accurate and consistent plan-
ing results, we do not recommend sharpen-
ing knives yourself. Instead, just replace
dull knives or have them professionally
sharpened.
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-setting jig that is included with the
Model G0815 is designed to set the knives 0.049"
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 27 for options).
