BELT TENSION

Inspect the tension of the belts frequently during
the first few times you use the planer. Belts often
stretch during this trial period. If they require
tightening, proceed as follows:
1. Remove the belt guard and the rear panel.
2. Loosen the bottom nut on the motor
adjustment screw (Fig. 12) with a 17mm
wrench.
3. Turn the top nut on the adjustment screw to
lower the motor plate, which will increase the
belt tension.
4. Proper tension is achieved when there is
slight deflection in the belt midway between
the pulleys, using moderate finger pressure.
5. Tighten the bottom nut on the adjustment
screw (Fig. 12).

PULLEY ALIGNMENT

The pulleys should be in line for proper belt
operation.
1. Remove the belt guard and place a straight
edge against the faces of both pulleys (Fig.
13).
2. If the straight edge does not lie flat on both
pulley faces, open the rear panel and loosen
the four hex nuts on the motor plate (see
Fig. 12) with a 12mm wrench.
3. Nudge the motor left or right until the pulleys
are in alignment.
4. Tighten hex nuts and replace covers.
