8. Evenly move the secondary idler bracket to set the belt tension.
Note: Belt tension should be set so that a seven (7) pound force
will deflect the belt 1/4".
9. Tighten the nuts holding the secondary idler bracket in place.
10. Restore power to the unit.
REPLACING/SERVICING THE PRIMARY DRIVE POLY V-BELT
1. Unplug the unit.
2. Remove the rear access panel by loosening the screws and lifting the
panel off the screws.
3. Inspect the primary drive poly V-belt for worn or frayed areas.
• If the belt is in good condition, continue to set the belt tension in
step 7.
• If the belt is frayed or damaged, continue to step 4.
4. Using a 9/16" wrench, loosen the two screws holding the idler bracket.
5. Loosen the idler adjustment screw behind the idler pulley in order to
release the tension enough to remove the old belt.
6. Place the new belt in position over the motor drive pulley, then over the
idler pulley, and finally around the driven pulley.
Note: The belt must be fully engaged in all the grooves of both
the driven pulley and the motor drive pulley. Rotate the
motor drive pulley by hand to ensure that the belt is riding
on all the grooves.
7. Tighten the screw behind the idler pulley to set the belt tension. The poly
V-belt requires a 4-5 pound force to deflect the belt 3/8".
Note: The poly V-belt will feel looser than a standard V-belt.
8. Tighten the two screws holding the idler bracket.
9. Test run the mixer for 60 seconds. Check the belt tension and adjust if
necessary.
