Maintenance Information
Regular maintenance is essential to a game's continuing contribution to the operator's
earnings.
Lubrication
The two main lubrication points of the Ball Shooter Lane Feeder mechanism are the pivots for
the arm. The mechanisms of other playfield devices are somewhat similar to the Ball Shooter
Lane Feeder Device, and have the same lubrication requirements. Amedium 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 EI165, is a recommended lubricant.
Switch Contacts
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-inchgap.
Cleaning
Good game action and extended playfield life are the results of regular playfield cleaning.
During each collection stop, the playfieldglass should be removed and thoroughly cleaned and
the playfieldshould be wiped offwith 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 carnauba 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
playfieldplastics because they may dissolve the plastic material or damage the artwork.
