5. To align pulleys, there is a variety of adjust-
ment. For example:
A. The band wheel pulley can be slid along
the shaft.
B. The three-step pulley can be adjusted
away from the base by doubling up a
washer.
C. The motor pulley can be turned around
and repositioned on the motor shaft.
Remember, the motor should remain level
after any adjustments.

V-Belts 3. Adjust the motor back and forth until the V-
grooves line up with the V-grooves on the
three-step pulley.
4. Slip either the 31" or 33" belt over the motor
pulley and the step pulley, depending on the
desired speed. For general woodworking, we
recommend setting the lower belt for the
fastest rate of speed. See
Figure 16 for
speeds.
You may have to back off the nuts on the
motor adjustment bolts to allow enough
motor swing to attach the belt.

In order to ensure proper power transmission
from motor to band wheels, the pulleys should be
aligned and the belts should have proper tension.
To begin pulley and belt assembly:
1. Place the A32 belt in the wheel pulley groove
and the last groove in the stepped pulley as
shown in
Figure 14.
2. Tension the belt by pushing the stepped pul-
ley down in the shaft slot. The belt deflection
should be approximately
3 ⁄
4
" when you push
on the center of the belt (similar to Figure
15) with your index finger.
