ALL
power to the dispenser is off.
2. Remove both side panels first, then remove the rear
panel of the machine.

on the side of the belt idler arm spring adjustment
mechanism. Relieve the tension on the spring by
turning the adjustment screw near the label which warns:
DO NOT ADJUST

idler arm by placing needle nose pliers on one end of the
spring and pulling the end out of the retainer.
4. Remove the nut and idler arm from the pivot point of
the belt idler arm assembly.
5. Remove the belt idler arm and inspect the pivot point.
These areas should be free of rust, debris, or
dried lubricant. If any of these substances are found,
they must be removed.

of emery cloth and apply anti-seize compound.

SOME UNITS IT IS POSSIBLE TO OVERTIGHTEN
THE LOCKING NUT AND CAUSE THE IDLER ARMS
TO BIND. THE ARMS SHOULD MOVE FREELY.
8. Repeat the process for the torque idler arm.
9. Install the belt making certain that there is no grease
on the belt or pulleys. Step to the side of the unit and
view the belt to determine whether or not it is properly
aligned (straight from top to bottom).
10. Reinstall the torque idler arm spring and the belt
idler arm spring and turn the adjustment screws
returning the adjustment nuts to the pencil marks you
placed on the side of each adjustment mechanism in
step 3 above.
