Always inspect V-belts for damage or dete-
rioration when adjusting tension. Should
you find evidence of fraying, cracking, or
other damage, replace the belt immediately.
Belt breakage could lead to mechanical
damage or operator injury.
Belts and pulleys will be hot after operation.
Allow them to cool before handling.
To adjust V-belt tension:
DISCONNECT MACHINE FROM POWER!
1.
Remove right access panel.
2.
Loosen motor mount fasteners shown in

V-Belt Removal/Replacement
Replace the V-belt if you notice fraying, cracking,
glazing, or any other damage. A worn/damaged
V-belt will not provide optimum power transmis-
sion from the motor to the drums.
V-belt removal and replacement is simply a matter
of loosening the V-belts until you can roll them off
the pulleys, replacing them with a MATCHED set,
then re-tensioning them.
Note: A matched set means both the V-belts
are the same size and also have the same serial
number.
Pulley Alignment
Pulley alignment is another important factor in
power transmission and belt life. The pulleys
should be parallel to each other and in the same
plane (coplaner) for optimum performance.
Each pulley can be adjusted by loosening the set
screw that secures the pulley to the shaft, sliding
the pulley in/out, and retightening the set screw to
lock the pulley in place.
To align pulleys:
DISCONNECT MACHINE FROM POWER!
1.
Remove right access panel, loosen motor
2.
mount fasteners, and remove V-belts.
Place straightedge across face of motor pul-
3.
ley and front drum pulley to check alignment.
The straightedge should sit evenly on top and
bottom part of both pulleys.
Repeat Step 3 with straightedge placed
4.
against motor pulley and rear drum pulley.
Loosen pulleys and adjust them as neces-
5.
sary until they are all coplanar with each
other, and then tighten set screws.
Reinstall and properly tension V-belts, tighten
6.
motor mount fasteners, and reinstall right
access panel.
