Slide the square head bolts into the channel provided in the motor bracket. Place the motor into
position, finger tighten the nuts to temporarily secure the motor. Attach the motor adjustment (belt
tension) assembly.

Slide the motor within the motor bracket to ensure proper pulley alignment (see Figure 3). A
straight edge across the face of the driven pulley should be parallel to the belt once proper

mid span under medium finger pressure (2-3 lbs.) for every foot of span is approximately
belt tension. Lock the motor adjustment (belt tension) assembly once proper belt tension has been
achieved.

WARNING: EXCESSIVE BELT TENSION IS THE MOST FREQUENT CAUSE OF BEARING
