-16- G1033 20" Planer
5. Place Block ''A'' under the cutterhead with a
.040'' feeler gauge above it and raise the
table until the block reaches the cutterhead.
Center one of the knives at the bottom of
the cutterhead as you raise the table. Rock
the cutterhead backward and forward as
you raise the table and stop when the knife
just touches the feeler gauge. See Figure
17.
6. The table is now positioned correctly. Lock
the table in place.
7. Remove the feeler gauge and move the
block to the right end of the infeed drive
roller.
Feed Roller Speed
The infeed and outfeed rollers power the stock
through the planer. They keep boards flat and
provide smooth movement. The power feed fea-
tures two feed rates - 16 FPM and 20 FPM. The
speed can be changed by moving the feed con-
trol knob when the machine is running. See
Figure 15. Moving the knob toward the machine
(Pos B) produces the 20 FPM feed speed, away
from the machine (Pos D) produces 16 FPM and
a center position (Pos C) places the gearbox in
neutral.
Figure 15. Feed speed control.
Roller Adjustment
The infeed and outfeed rollers must be set at
.040" below the level of the cutting edge of the
knives. To set the height of the infeed and out-
feed rollers:
1. Disconnect the planer from its power
source.
2. Make sure the knives are set correctly.
3. Remove the chain cover. Refer to the pre-
run check for removal instruction.
4. Loosen the cap screw that holds the static
chain tensioner and swing the tensioner out
of the way. See Figure 16.

NOTICE
The feed rate must be set before feeding
lumber into the planer. DO NOT attempt to
change speeds after the planing operation
has begun. Damage to the gearbox will
result.
