9.0 Adjustments Disconnect machine from power source before making adjustments (except feed rate). 9.1 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 (Figure 11) 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 (Figure 11). 9.2 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 (Figure 12). 2. If the straight edge does not lie flat on both pulley faces, as shown in Figure 13, open the rear panel and loosen the four hex nuts on the motor plate (these are shown in Figure 11) with a 12mm wrench. 3. Nudge the motor left or right until the pulleys are in alignment. 4. Tighten hex nuts and replace covers. Figure 11 Figure 12 Figure 13 11

Adjustments
Disconnect machine from
power source before making adjustments
(except feed rate).
9.1
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 (Figure 11) 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 (Figure 11).
9.2
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
(Figure 12).
2.
If the straight edge does not lie flat on both
pulley faces, as shown in Figure 13, open
the rear panel and loosen the four hex nuts
on the motor plate (these are shown in
Figure 11) with a 12mm wrench.
3.
Nudge the motor left or right until the pulleys
are in alignment.
4.
Tighten hex nuts and replace covers.
