ADJUSTMENTS
ADJUSTING DRIVE BELTS
The cutterhead drive belt and the feedgear drive belt
need to be checked periodically and retightened if neces-
sary. Belts will stretch with use, especially when they are
new and are breaking in. Both drive belts are located
behind the machine's side panel. FIG. 23, A & B.
CHECKING THE DRIVE BELT
1. Make sure that the planer/jointer's switch is turned off,
and the plug is disconnected from the power source.
2. Remove the Speed Control Knob (#155, FIG. 23, B)
3. Take off the the left side panel (#4, FIG. 23, A) by
loosening the six hex head screws (#3) that secure the
panel to the cabinet, and also lift up the cutterhead cover
(#13) to reveal the motor, pulleys and belts.
4. Check the drive belt tension with finger/thumb pres-
sure. The drive belt should not deflect more than 3/8" to
1/2" in the center. FIG. 24.
TENSIONING THE DRIVE BELTS
5. Check the Cutterhead Drive Belt (#145, FIG. 25, A)
tension with thumb pressure. The drive belt should not
give more than 3/8" to 1/2" in the center.
6. From outside, rear of the machine, loosen the four
Nuts (#144, 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.
7. When the belt tension is correct, tighten the motor
mounting nuts that were done in step 4.
8. The Feed Roller Belt (#152, C) is automatically
tensioned with the wheel bracket Spring (#184, D) and
requires no adjustments.
9. The Feed Roller Chain (#140, E) is factory set and
should not require any setting changes. However, to
increase or decrease the chain overlap, the Bearing with
Sleeve (#228, F) can be adjusted in or out with the
Carriage Bolt & Nut (#131, 135).
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.
CAUTION: Keep your hands clear of the sharp knives.
