Chicago Gaming Medieval Madness Remake - Manual (Page 82)

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 fo r any chips,
nicks, or pits. Replace any damaged balls to prevent playfield damage .
MAINTENANCE INFORMATION
LUBRICATION
SWITCH CONTACTS
CLEANING
The two main l ub r ication points of the Ba l l 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 lubrica t ion 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 pivo t points of the
Left and Righ t Kickers ("Slingshots") all requ i re lubricationas a regular servicing procedure .
Lubr i cation t o ensure proper operation also app l ies to the target b lades of the Dro p Targets . MBI
Instrument Grease , also known as Drop Target Switch Lubricant isrecommended.
Playfield Switches
For proper game operation, switch contacts should be free of dust, dirt, contamination, and corrosion.
Blade switch contacts are plated to res
i s t corrosion. Cleaning blade switch contacts requires gentle
closing of the contacts on a clean business card o r piece o f paper , and then pulling the paper about 2
inches , which should restore the clean contac t surface . Ad j ust the switch con t acts to a 1 / 16- i nch gap.
Flipper Switches
This game uses
t he new Fliptronic II E l ectronic Flipper System . The End-of-Stroke switc h es are
NORMALLY OPEN. The switch should close when the flipper is energ i zed. All E.O . S. sw i tches 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 t ungsten high
current switches , as intermittent operation could occur.
Note : Unlike the old style of flipper, an E.O . S . switch failure doe s not harm the flipper . The game notifies
the operator that the switch is misadjusted in the test report , but continues to play. The E.O . S. switches
are a means by which the new electronic flippers fee l and pla y with all of the subtleties of the old flippers.
Regular , more extensive, p l ayfield 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 pol i sh may be used sparingly , to prevent a buildup on the playfield surface.
Do not use cleaners conta i ning pe t roleum d i st i llates on any p l ayfield plastics because they may dissolve
the plastic materia l or damage the artwork .
