X. ROUTINE MAINTENANCE ON
LOCATION:
After successful completion of the Self Diagnostic
Test Procedure, set the game up for play. Exercise
each roll-over, thumper bumper, slingshot, etc., by
hand until each switch assembly on the playfield
has been checked for proper operation.
If
actuating a switch assemble results in intermittent
or no response, clean contacts by gently closing
them on a clean business card or piece of paper
and wiping until
they wipe clean. Re-gap, if
necessary, to 1/16". Do not burnish or file Gold
Plated Switch Contacts.
XI. SWITCH ASSEMBLY ADJUSTMENTS:
GENERAL:
All
switch assemblies
consist
of leaf
spri ngs,contacts,
separators,
plastic tubi ng and
screws to hold them to the mounting surface.
Before attempting to adjust a switch assembly,
make sure that these screws are tight. If not,
tighten screw closest to the contact end of the leaf
spring first. This will prevent the assembly from
being secured in such a manner that the leaf
springs tend to fan out. In general, all leaf springs
are adjusted for a 1/16" gap in the open position
and .010" over-travel
or wipe in the closed
position. All contact should be in good condition.
Unless otherwise instructed, they should be dry or
non-lubricated.
All contacts should be free of dust
and dirt. Contacts, with the exception oftheflipper
button switch assemblies are plated to resist
corrosion.
Filing or burnishing breaks the finish
and encourages corrosion.
Clean by closing the
contacts over a clean piece of paper (e.g. a lintfree
business card) and wiping gently until the contacts
are clean. For the flipper button switch assemblies
ONLY: Tarnish can be removed with a contact file
followed by burnishing tool. Severely pitted
contacts must be placed and adjusted only when
they are found to be a source of game malfunction.
XII. SERVICE HINTS:
The Bally playfield has an improved tuff-coat finish
with excellent wearing properties. Life expectancy
of the playfield as well as play appeal, can be
extended by periodic cleaning.
DO: Bally recommends you clean your playfield
with Wildcat #125 (Wildcat Chemical Co. 1349 East
Seminary Drive; Fort Worth, Texas
76115;
Phone
1-817/924-8321).
Wildcat #125 is a combination
cleaner and polish. Bally has tried and tested this
product and found it to be very effective. If Wildcat
#125 is not available, Bally suggests you ask your
distributor to order it. Inspect and hand polish the
ball in a clean cloth. A chipped ball must be
replaced. It can ruin the finish on the playfield in a
short period of time.
DON'T: Use water in large quantities,
highly
caustic cleaners, abrasive cleaners and cleaning
pads on the playfield, or allow a wax or pOlish build
up. Waxes yellow with age and spoil appeal.
