MAINTENANCE INFORMATION
LUBRICATION
The two main lubrication points of the Ball Release mechanism are the pivots for the arm.
The
mechanisms of other playfield devices are somewhat similar to the Ball Release device, and have the
same lubrication requirements.
A medium viscosity oil (switch target grease) is satisfactory for these
devices.
Because of the functional design (arm-actuated via solenoid plunger operation), the pivot points of the
Left and Right Kickers ("Slingshots") all require lubrication as a regular serviCing procedure.
Lubrication to ensure proper operation also applies to the target blades of the Drop Targets.
MBI
Instrument Grease, also known as Drop Target Switch Lubricant, with a Williams' part number of E1165,
is a recommended lubricant.
SWITCH CONTACTS
Playfield Switches
For proper game operation, switch contacts should be free of dust, dirt, contamination, and corrosion.
Blade switch contacts are plated to resist corrosion.
Cleaning blade switch contacts requires gentle
closing of the contacts on a clean business card or piece of paper, and then pulling the paper about 2
inches, which should restore the clean contact surface. Adjust the switch contacts to a 1/16-inch gap.
Flipper Switches
r>.
This game uses the new Fliptronic II Electronic Flipper System.
The End-of-Stroke switches are
NORMALLY OPEN. The switch should close when the flipper is energized. All E.O.S. switches are gold
flashed computer grade leaf switches.
Only low computer current is carried through these switches. DO
NOT FILE or abrasively clean these switches! DO NOT REPLACE these switches with the old style
tungsten high current type switches as intermittent operation could occur.
Note:
Unlike the old style of
flipper, an E.O.S. switch failure does not harm the flipper. The game notifies the operator of the switch
being mis-adjusted in the test report, but continues to play. The E.O.S. switches are a means by which
the new electronic flippers feel and play with all of the subtleties of the old flippers.
CLEANING
Good game action and extended playfield life are the results of regular playfield cleaning. During each
collection stop, the playfield glass should be removed and thoroughly cleaned and the playfield should be
wiped off with a clean, lint-free cloth. The game balls should be cleaned and inspected for any chips,
nicks, or pits. Replace any damaged balls to prevent playfield damage.
Regular, more extensive, playfield cleaning is recommended.
However, avoid excessive use of water
and caustic or abrasive cleaners because they tend to damage the playfield surface. Playfield wax (or
any camauba based wax), or polish may be used sparingly, to prevent a buildup on the playfield surface.
Do not use cleaners containing petroleum distillates on any playfield plastics because they may dissolve
the plastic material or damage the artwork.
