The belt system has pulleys, idlers and a tensioner. Check that the pusher boxes slide smoothly
back and forth. Check the belts periodically for correct tension – they do not stretch, so do not
attempt to over-tension them.
Ensure that the coin scraper system is fully intact and working smoothly and freely - replace any
suspect parts.

Fault Finding
7.1
Methodology
It is of mutual interest that your pusher is kept in excellent working condition, therefore when
required please order original replacement
parts from your distributor or Harry Levy Amusement
Contractor Ltd.
If a fault occurs with any electrical system
SWITCH THE MACHINE OFF.
Check that:-
a) There is a suitable mains supply.
b) All fuses are intact.
c) All plugs and sockets are correctly mated.
d) No wires are trapped, damaged or broken.
e) All wires are properly secured to their terminals and pins.
Wiring check.
A visual inspection will reveal the general condition of the wiring. A more thorough test using a
continuity tester will be needed to check apparently intact wires, however once a machine has
been playing successfully for some time wiring is not usually at fault.
Device testing.
Disconnect the machine from the mains supply then check the physical condition and operation
of the suspect device (remove from the machine if necessary). Bench test if possible using a
suitable power supply.
In general PCB's are not user serviceable. Should a problem develop indicating a board fault it
is recommended that the board be returned to your distributor/Harry Levy for repair.
7.2
Systems Checking
When a fault occurs that affects the whole of the machine, the power supply and regulation
system should be investigated first.
Check the input, and output fuses.
Refer to schematics and drawings to check power connections, voltages etc.
If the fault is not visual, or easily measurable it is often helpful to disconnect the outputs from
the PSU, check that the PSU is functioning then connect the loads one at a time.
It is easy to identify the faulty system, then use a similar technique within that system (such as
disconnecting all hoppers) to identify the faulty component.
