GILLIGAN'S ISLAND 1-46
NUUNTENANCEINFORMATION
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.
Note that the mechanism of other playfield devices are somewhat similar to the Ball Shooter Lane
Feeder Device; and have the same lubrication requirements as the Ball Shooter Lane Feeder Device. A
medium viscosity oil (20Wor 30W) 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 C'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 20-
8886, 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 1I16-inchgap.
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 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 playfield plastics because they
may dissolve the plastic material or damage the artwork.
