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.

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,
