MAINTENANCE
The most common cause of vendor or coin changer
malfunction is the accumulation of foreign material
in its working parts. Keeping your COINCO changer
clean is a simple matter, since most of its
components are made of Noryl. Usually a damp cloth
is all that is required. The frequency of such cleaning
will depend on where the equipment is located.
It is suggested that a regular cleaning program be set
up, particularly for the coin tubes, coin chutes, payout
base and acceptor.
If heavy soil accumulates, remove the parts from the
coin changer and clean with water and mild
detergent or soap. Rinse with clean water and dry
thoroughly before replacing in changer.
DO NOT USE A PETROLEUM BASE CLEANING
SOLVENT.

SERVICING THE COIN CHANGER
A. COIN SWITCHES
In rare instances, the tripping (or "break")
position of the coin switch may require slight
adjustment. If so, bend the wire carefully at the
point where it is attached to the switch, after
testing as follows:
1.
Remove the back coverplate of the changer.
2.
Remove the electronic logic board. (See
removing the electronic board)
3. Move the switch wire downward and allow
it to return to its rest position. The wire
1
should ride in the middle of the slot all the
way to the bottom.
4. Check the individual switch wire setting as
follows: (See Figure 6-1)
NOTE:
The following steps (a, b, and c) pertain
only to the
S75-9800A.
The
S75-9800B
has no
calibration markings except for the
1 OC
coin
switch, which is the most critical because of the
light weight of the
10C
coin.
a.
25¢ Coin Switch and Wire Assembly
The switch wire should extend through
the
25C
chute ONLY. Check the break
position of the switch by moving the
wire downward and allowing it to return
slowly while listening for the click. This
should occur when the wire is at the top
calibration mark on the left side of the
switch slot as it returns to the rest
position.
b.
10¢ Coin Switch and Wire Assembly
The
1
OC
coin switch is checked in the
same manner as the
25C
coin switch.

(downstroke) and break (upstroke) of the
coin switch should occur between the
two increment marks on the left side of
its switch slot.
