Access to components on the underside of the playfield can now be had as well as access to
the main power supply and fuses, located in the bottom of the main cabinet.
c) Access to Backbox:
Access to the interior of the backbox may never be necessary – there are only a few
serviceable parts inside it. These include the fluorescent light tube, fluorescent starter,
and fuses on the main CPU circuit board unit.
To gain access to the backbox interior, remove the four Phillips head screws that hold the
wood molding down at the base of the backglass. Then remove the wood-molding piece.
To remove the glass, first pull the bottom of the glass toward the front of the machine.
Once it clears the backbox, lower it down toward the playfield glass. Then carefully
remove the backglass and set it in a safe place.
Once the backglass is removed, you will have access to the score display and “map”
lights printed circuit board assembly, and the main CPU circuit board assembly, located
above and behind the score/map circuit board unit.
8) RECOMMENDED MAINTENANCE:
The owner can perform general maintenance on the game whether experienced with pinball
machines or not.
a) Glass Cleaning:
Both sides of the playfield glass should be cleaned regularly. You can remove the
playfield glass as described in the section on “Access to Playfield & Game Interior” earlier
in this manual.
DO NOT use excessive glass cleaner on the backglass. Excessive glass cleaner can run
down to the bottom of the backglass, and creep up onto the backside. This can cause
possible damage to the silkscreened artwork on the backside of the glass and cause it to
crack, “lift”, and peel off of the glass over time. The backside of the backglass seldom
needs to be cleaned, but if it does, use only a minimal amount of glass cleaner, and
make sure it is all wiped completely dry before re-installing the backglass in the game.
