TO TENSION/REPLACE THE V-BELTS:
1. DISCONNECT PLANER FROM POWER!
WARNING: V-belts
and pulleys will be hot
after operation. Allow
them to cool before
handling them.
2. Remove the V-belt
cover from the left
side of the machine
to expose the belts, as
shown in figure 23.
NOTE: A collection of
black belt dust at the
bottom of the belt
cover is normal during
the life of the belts.
3. Remove the front
cabinet panel to ac-
cess the motor, as
shown in figure 24.
4. If the V-belts need to be replaced, raise the
motor to release the belt tension (refer to the
next step for instructions), roll them off the
pulleys, then replace them as a matched set of
3.
5. To adjust the V-belt tension, loosen the top
motor mount hex nuts (see Figure 39), then
adjust the bottom hex nuts to raise or lower
the motor.
NOTE: The V-belts are
correctly tensioned
when there is approxi-
mately 3/4" deflec-
tion when moderate
pressure is applied
to them midway be-
tween the pulleys.
6. When the V-belts are correctly tensioned,
make sure the motor mount hex nuts are tight,
then replace the cabinet cover and the belt
cover.
TABLE HEIGHT CHAIN TENSION
The table height chain transfers movement
from the elevation hand wheel to the col-
umns that control table height. The chain drive
can be adjusted to remove slack if the chain
stretches over time or is loosened during table
leveling procedures.

To adjust the table height chain tension:
1. DISCONNECT PLANER FROM POWER!
2. Remove the front
and rear cabinet pan-
els to gain access to
the chain system, as
shown in figure 26.
During the next step, DO NOT let the chain
fall off the sprockets. It can be very difficult to
return the chain to its proper location on the
sprockets without changing the table adjust-
ments.
3. Loosen the lock bolts shown in figure 26,
and push the idler sprocket against the chain
with moderate hand pressure, then while
maintaining the pressure on the idler sprocket,
re-tighten both lock bolts.
4. Clean and lubricate the chain and sprockets
(refer to Table Height Chain & Sprockets for
detailed instructions).
FEED ROLLERS, CHIP BREAKER & PRESSURE

It is essential that the feed rollers, chip breaker
and pressure bar are set at the correct distance
below the cutterhead to ensure that the work-
piece moves through the planer evenly and the
correct distance from the cutterhead knives.
Dist. Below Knife Edge at BDC (Bottom Dead
Center).
A. Infeed Roller 0.040".
B. Chip Breaker 0.040".
