-26- G1021 15" Planer
TO CHECK BELT TENSION:
Squeeze the V-Belts at their midpoints with mod-
erate finger pressure. You should be able to
deflect each V-Belt about
3
/4". Belts will rarely be
too tight, but will sometimes be too loose.
To adjust belt tension:
1. Loosen the two bolts that hold the motor/pul-
ley assembly to the planer.
2. Insert a wooden lever of suitable strength
and pry the motor up to increase belt ten-
sion. See Figure 28.
3. Maintain lever position and check belt ten-
sion. Re-adjust if necessary.
4. Tighten the bolts and check belt tension
again. Repeat steps 1-3 as necessary.
5. Ensure that the pulleys are still in alignment.

The gearbox is located just behind the hand-
wheel on the right side of the planer. The gearbox
transfers power from the belt-driven cutterhead to
the power feed rollers. The two-speed transmis-
sion is controlled by a push/pull lever on the right
side of the planer. When engaged, the power
feed rollers will move lumber through the planer
at either 16 or 20 feet-per-minute. The center
lever position is neutral.
TO INSPECT THE GEARBOX:
1. Loosen the socket head cap screw on the
gearbox cover. Gently pull the cover off the
roll pins that hold it in place.
2. Check the bolts holding the sprockets in
place. Inspect the drive chains to ensure that
the cotter pins are in place. Replace the pins
if necessary. See Figure 29.

Loosen these bolts before
adjusting belt tension.
WARNING
DO NOT make adjustments while the planer
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making adjustments.
Failure to comply could result in serious
injury.
