10.Install a flanged lock nut onto this motor stud.

Tighten the flanged lock nuts, using a %-inch wrench, until almost tight. It will be easier to tighten lock nuts if the head is tilted to approximately 45 °. See page 34 for instructions on tilting head.

NOTE: Do not over-tighten the flange nuts. The motor should slide in the grooves to allow tensioning of the belt.

12.Check that the poly "V" belt is on both pulleys being sure that it is centered on each pulley.

13.Check that the pulleys are in line by sighting down the side of the large pulley te see if it lines up with the small pulley. If the pulleys are not in line, loosen the set screw holding the pulley on the motor shaft and position the pulley. A notch in the small end of the motor support is provided for access to the set screw and belt.

14.Belt tensioning is done by tightening the wing nut which pulls the motor down. The motor slides on the

three (3) spacers and is locked in place by the flanged lock nut at the threaded stud.

Belt tension is important. Over tensioning may cause vibration while too little tension may allowthe

belt to slip under heavy loads,
