ROUTINE MAINTENANCE INFORMATION

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 using only a non-
abrasive sprayed liquid glass cleaner and a soft cloth. The playfield should be wiped off with a clean,
lint-free cloth. The game steel 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.

GLASS PARTS
Wear protective gloves and use both hands when carrying or moving parts made of glass. Glass
pieces can fly eight feet (two meters) or more from the point of impact.
SERVICE INFORMATION
Only trained personal should service the game. Always turn off power and unplug the game
before attempting any service!

HIGH VOLTAGE CONSIDERATIONS
CRTs and their power supplies can retain energy for long periods of time after the power has been
turned off. This is especially true when a defective circuit prevents a normal discharge. Connect a
very well insulated ground strap to the metal chassis. Slide the free end of the strap under the CRT
anode cap until contact is made. Wait two minutes for charge recovery, then discharge the anode a
second time.

RADIATION
The high voltages used in the Video Monitor Assembly are capable of generating X-rays under fault
conditions. Do not substitute high voltage components or modify the circuit without factory
authorization. Follow the manufacturer's directions for measuring and adjusting the CRT anode
voltage.

BATTERY
Note the position of the battery. Gently lift the contact arm to release tension. Do not bend the arm.
Slide the battery out of it holder. To reinstall the battery, orient the cell near the holder and slide it
under the contact arm. Do not force the battery into the holder.
CAUTION
Danger of explosion if battery is incorrectly replaced. Replace with only the same or equivalent type
recommended by manufacturer. Do not attempt to recharge these batteries. Avoid direct shorts across
terminals or from terminals to ground. Dispose of used batteries according to manufacturer's
instructions.
