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.
11. Install the wing nut on the threaded stud.
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 to 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 foraccess tothe setscrew
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.
