GENERAL
NEVER EX'?ERlMENT with any of the mechanism. Locate any trouble
wit~ the aid of Wiring Diagrams or Operating
&
Servicing Infor-
mation sup~lied with the machine, then check for prouer adjust-
ment of the units involved before making any changes. Imuroner
adjustment or make-shift rensir will only cause serious damage
to other parts of the machine or repeated failure of the oart.
NOTE: Always look for a possible loose wire, bad
connection at a olug and socket, broken or
unhooked sorings on step-uu units, relays,
etc., before adjustments are made or wires
reconnected.
2. FUSES
IMPORTANT: Never reolace fuses with any rating other than soee-
ffied on the fuse
biock;
this
block
is located adjacent to the
transformer.

LUBRICATION
Over-lubrication causes far more trouble in coin Onerated equin-
ment than under-lubrication. practically all cases of Door con-
tact on switches and winer discs are due to 011 or grease, or 011
vapor, which forms a film or residue on the contacts and will not
allow current to oass throueh. Excess lubricant may also seen in-
to clutch6:1 cau~lng them to sllp.
IMPORTANT: NEVER USE VASELINE FOR LUBRICATION OF ANY PART OF THE
MACHINE. Vaseline is not a true lubricant. It leaves a dirty and
gummy residue and it becomes very thick when cold. A soecial Coin
Machine Lubricant 1s supplied with each machine.
STEP-UP Levers, Ratchets, Cams, Shafts and other sliding or os-
cillating ~erts should be very lightly greased with soee1sl Coin
Machine Lubricant (suuolied with machine) not oftener than every
six months. The bakelite discs (biscuits) on the ~otor Units end
Sten-uo Units will require lubrication with the soecisl Coin
Machine Lubricant only after the greAse is comnletely evanorsted
(3 to 12 months, de~endlng on climate) or when the film of ~rease
becomes dirty. In either event, clean the parts thoroughly with
a solvent, then a~ply en extremely thin coat of the soecia1 grease.
Solenoid Plungers should not have a lubricant of any kind.
Should t~ere be a slu~p,ish tendency or
if
ulunr,ers are sticking,
the nnrts should be cleaned with a solvent and ilRked graohite
applied on reassembly.
SWITCH ADJUSTMENT
BEFORE ADJUSTING SWITCHES, MAKE CERTAIN THE SCREWS HOLDING
THE SWITCH STACKS ARE DOWN TIGHTLY.
BAKELITE SPACERS
IN
THE
SWITCH STACKS,
DUE TO EXCESSIVE MOISTURE, HAVE OCCASIONALLY
SHRUNK BY DRYING
OUT,
CAUSING
POOR
ADJUSTMENT.
