NOTE: The following information is for models

Installing Accessory Timing Cam
Non-electronic, rotary coin drop tumblers have eight
accessory cams in the literature package. These allow
you to change your vending times. Refer to Table 13.
Timer motor rpm is printed on the timer motor.
Removal of Existing Timing Cam
1. Rotate cam by hand until “V” notch lines up
beneath the ratchet tooth. Refer to Figure 24.
2. Insert narrow screwdriver under nylon cam, close
to the clock shaft. Lift gently off shaft. Make sure
that pressure is directed upward and that the “V”
notch clears the ratchet tooth.
Installation of New Timing Cam
1. Insert drive fork into timing cam with wide prong
in wide hole of cam.
2. Position timing cam and drive fork over the timer
shaft, aligning the timer flat with the drive fork
and the “V” notch with one of the ratchet teeth.
3. Press timing cam down firmly to seat timing cam
onto the motor shaft.

4. Remove all accumulated time by turning cam
counterclockwise until switch shuts off. Apply
moderate clockwise pressure to fully seated
timing cam and drive against the timing motor
shaft. Meter must be advanced electrically for
one cycle before an accurate measure of time can
be made.
