V-Belts

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.

pulley V-belt in place.

2.Tension the belt by pushing the stepped pul- ley down in the shaft slot. The belt deflection should be approximately 34" when you push on the center of the belt (similar to Figure 15) with your index finger.

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.

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.
