Assembly Procedure
To assemble the hopper:
1. Replace the disc:
a. Slide the drive shaft end of the disc into the driving boss, ensuring the slot
on the shaft engages with the drive pin in the gearbox.
b. Insert the four disc securing screws in the center of the disc and tighten.
c. Place the second coin wiper pawl in position, insert the screws and tighten.
d. Place the second coin wiper spring in position, insert the two securing
setscrews and tighten.
e. Place the spigot and coin stirrer in position.
f. Insert the center bolt through the center hole of the spigot and coin stirrer
and tighten onto the driving boss.
g. Place the coin runner on the two studs. Screw on the two nuts and washers,
but do not tighten. Locate the point of the coin runner as close as possible to
the spigot without rubbing, and ensure free running of the disc underneath
the coin runner. Use shims if required.
h. Slide the hopper coin chute under the two bolts holding the coin runner and
tighten the nuts.
2. Replace the bowl assembly:
a. Place the bowl assembly (still attached to the casting plate) in position on the
base of the hopper.
b. Insert the four spring-loaded bolts into the casting plate and tighten.
c. Place the photo-optic detector in position, insert the screw and tighten.
d. Place the fixed bolt in position so that it restrains the wire for the photo-opto
detector, and tighten.

7.7 Test Procedure

To test the hopper after servicing, follow the hopper test procedure outlined in the
chapter Machine Modes.

7.8 General Maintenance

For the general maintenance of the hopper:
1. Remove any dust from the photo-optic detector with a soft paintbrush or by
blowing through a drinking straw. Dirt accumulating on the detector can result
in faulty coin counting.
2. Check that the coin pawl pre-load leaf spring has not been bent away from the
coin pawl. Replace if necessary.
