ADJUSTMENTS
ADJUSTING DRIVE BELTS
The cutterhead drive belt and the feedgear drive belts need
to be checked periodically and retightened if necessary.
Belts will stretch with use, especially when they are new
and are breaking in. Both drive belts are located behind the
machine's front and rear covers. FIG. 30 & 31. To inspect,
adjust or change the bdrive belts:
1. Make sure that the planer/jointer's switch is turned off,
and the plug is disconnected from the power source.
2. Raise the cutterhead guard to remove the front cover,
then unscrew the rear cover. This will expose both sides of
the machine and its motor, pulleys and belts.
TENSIONING THE DRIVE BELTS
3. Check the Cutterhead Drive Belt (#309, FIG. 30, A)
tension with thumb pressure. The drive belt should not give
more than 3/8" in the center. FIG. 32.
4. From the front of the machine, loosen the four Nuts
(#313, FIG. 30, B) 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 motor
mounting nuts that were done in step 4.
6. The Feed Roller Belt (#256, FIG. 31, C) requires no
adjustments. Its elasticity automatically applies tension.
7. The Feed Roller Chain (#248, FIG. 31, D) is automati-
cally tensioned with the Spring Assembly (#246, 247, 249,
E) and requires no adjustments.
NOTE: While the side panel and cutterhead cover are
open, remove any chips and dust that may have accumu-
lated with a dust collector or brush.
8. When all belts have been checked and any maintenace
has been done, replace the side panel and belt cover and
secure them in position with the screws.
REPLACING THE DRIVE BELTS
1. To replace the Drive Belt (#309), follow the same steps,
#3-5 above. Loosen the tension until the belt can be easily
removed from the Motor Pulley (#311) and Cutterhead Pul-
ley (#235). Once removed, reverse the steps to install and
re-tension the new belt on the pulleys. FIG. 30.
2. To replace the Feed Roller Belt (#256, FIG.31, C), sim-
ply stretch the elastic belt and postion it over the large, Flat
Belt Pulley (#257, E), then the Cutterhead Shaft (F).
