ADJUSTMENTS
To inspect, adjust or change the drive belts:
1. Make sure that the planer/jointer's switch is turned off,
and the plug is disconnected from the power source.
2. Remove the fence assembly, the Rear Guard (#91) and
the cabinet's rear Belt Cover Plate (#40) to expose the
motor, pulleys and belts. FIG. 29.
TENSIONING THE DRIVE BELTS
3. Check the
Cutterhead Drive V-Belt (#228, FIG. 30, A)
tension with thumb pressure. The drive belt should not give
more than 3/8" in the center. FIG. 31.
4. From outside, rear of the machine, loosen the four Cap
Nuts (#201, FIG. 32) that secure the motor in place. Lift the
motor to slacken the tension on the drive belt, or move it
down to increase the belt tension.
5. When the belt tension is correct, tighten the same motor
mounting cap nuts that were loosened in step 4.
6. The
Feed Roller V-Belt (#214), FIG. 30, B) is automat-
ically tensioned with the Spring (#229, C) and requires no
adjustments.
7. The
Feed Roller Chain (#227, FIG. 30, D) is factory set
and should not require any setting changes. However, to
increase or decrease the chain overlap, the Pulley with
Sleeves (#32, E) can be adjusted in or out with its center
Bolt and Nut (#20 & 31).
NOTE:
While the rear guard and belt cover plate are open,
remove any chips and dust that may have accumulated
with a dust collector or brush.
8. When all belts have been checked and any maintenance
has been done, replace the rear guard and belt cover plate
and secure them in position with their screws.
REPLACING THE DRIVE BELTS
1. To replace the
Drive V-Belt (#228), follow the same
steps, #3-5 above. Loosen the tension until the belt can be
easily removed from the Motor Pulley (#208 / 208A) and
Cutterhead Pulley (#94). Once removed, reverse the steps
to install and re-tension the new belt on the pulleys.
2. To replace the
Feed Roller V-Belt (#214), the Drive Belt
must first be removed. With the motor loose and lifted,
there should be enough slack to install a new Feed Roller
Belt. If not, the tensioning Spring (#229) can also be
unhooked to allow the Handle & Bracket Assembly (#217)
to swing loose. Re-fastened the spring once the belt has
been installed. Then reverse the steps to install the drive
belt and re-tension it on the pulleys.
3. When all work on the belts has been done, replace the
rear guard and belt cover plate and secure them in position
with their screws.
