2. PRECAUTIONS
2-l Cautions When Installing
This game is designed for indoor use only. The game must not be installed out-
doors or under the following conditions:
a. In areas directly exposed to sunlight, high humidity, direct water contact, dust,
high heat or exneme cold.
b. In locations that would present an obstacle in case of emergency, i.e. near fire
equipment or emergency exits.
c. On an unstable surface or subject to floor or other vibration.

2-2 Caution When Handling
a.
b.
C.
d.
e.
f.
g.
h.
i.
AC power must always be turned OFF, and the game unplugged, before
replacing any parts or connecting/disconnecting connectors.
When unplugging the game from an elecaical outlet, always grasp the plug,
not the cord.
Do not subject game to physical shock when transporting or moving it.
The power supply range is between 1 IO-120VAC, (switchable to 220 VAC).
The cabinet must be grounded with a securely connected ground plug.
Care must be taken at all times to avoid electrical shock whenever inspecting
or adjusting the game, particularly around the monitor.
Always return the levelers to the extreme “up” position before moving the
game, and separate the game into its two assemblies - cabinet and seat.
Adjustment is required whenever the game PC board, gun, steering wheel,
pedal assemblies or potentiometers are changed,
DO NOT attempt to repair the Printed Circuit Board (PCB). It contains
sensitive chips that could easily be damaged by even the small internal ‘voltage
of a multi-meter. Always return the PCB to your distributor for any repairs.
3. INSPECTION
NOTE: The Control Panel (dashboard) is shipped separately with the Monitor
Cabinet, and must be installed by the operator as described in Section 4-2.
The LUCKY & WILD Game cartons should be carefully inspected upon receipt to
insure that the game is complete and was delivered in good condition.
Inspect the game cabinet by doing the following:
1. Examine the cabinet exterior for dents, chips, or broken parts.
2. Unlock and open the rear service door and the front coin door.
Inspect the interior of the cabinet as follows:
a. Verify that all plug-in connectors (on the cabinet harnesses) are firmly
plugged in. DO NOT force connectors together. The connectors are keyed so
they fit only in the proper orientation. A reversed edge connector can damage
a PCB and will void your warranty.
b. Inspect the power cord to insure that there are no cuts or dents in the insula-
tion.
c. Inspect the power supply connectors.
d. Inspect other major sub-assemblies, such as the video display monitor, PCB,
gun assemblies, steering assembly and speakers. Make sure that they are
mounted securely and that all ground wires are firmly connected.

Roll the monitor cabinet to its intended operating area.
Roll the seat assembly up to and touching the front edge of the foot rest on the
front of the monitor cabinet.
Connect the two assemblies together by bolting the metal joints to the assem-
blies with the eight (8) bolts provided, as shown below.
NOTE: Whenever separating/moving the game, temporarily replace and
tighten the bolts into their respective assemblies to prevent losing them.
Lower the eight (8) levelers (4 on each assembly) of the game, and adjust all
levelers until the entire game is stable and rests firmly on the floor.

The Player one (1P) gun MUST be adjusted first. Calibration is performed
as follows:
a. Rotate the left gun (1P) until it is aligned with the upper left “+I’ icon. Be
careful not to align the gun higher than the “+” icon as this will cause the
gun to move abnormally during game play.
b. When the gun and “+” are aligned, squeeze the nigger. This will cause
Screen 2 to be displayed.
c. Rotate the left gun (1P) until it is aligned with the lower right “+” icon.
Be careful not to align the gun lower than the “+” icon as this will cause
the gun to move abnormally during game play. When properly aligned,
squeeze the trigger. This completes adjustment for the left gun.
Adjust the right gun (2P) in the same manner following steps 3a through 3c
above. When “OK ADJUSTMENT END” is displayed on the screen, the
proper gun adjusmrent has been completed.
Press the service switch to move to the next test screen, or return the test
switch to “OFF’ to return to the attract mode.
NOTE: If gun’s aim appears to be improper during game play, adjust the
gun(s) by following the procedure above.

6. HOW TO PLAY
l LUCKY & WILD is a game that allows one or two players to shoot and destroy
enemies that emerge on the screen by operating the steering wheel, the accelerator
and the brake. The left (IP) player operates the steering wheel, the accelerator, the
brake and the left gun. If there is a second player, that player operates the right (2P)
gun.
l Up to two players can play. When one player is playing the game, another player can
join in at any time. When two people are playing, the game ends, or continues, at the
same time for both players.
l After inserting the proper coin(s), a player(s) starts the game by pushing the white
start switch(s) located on the top of the dashboard.
l The gun(s) is fired with each pull of the trigger. If a player keeps the trigger
depressed, the gun fires continuously.
- The enemies emerge on the screen and attack using a machine gun and grenades.
- The player(s) attempts to repel the enemy attacks and avoid taking damage either
from the enemy’s bullets, grenades, or by colliding with another vehicle or enemy
wreckage. Each hit or collision reduces the “damage left” gauge.
- The game is over when the “damage gauge” in the middle of the bottom of the screen
runs out.
l The game has six stages. Each stage has a time limit. Stages are completed if the
player successfully arrests the boss within the time limit of the stage.
- If the player(s) fails to arrest the boss within the time limit of any stage, the stage
ends, but the boss gets away and the game still continues.
l Players can enter their high scores by using the steering wheel to select and stepping
on the gas pedal to set.
l Any initials entered are reset once the game’s power is turned off.

TROUBLESHOOTING - GENERAL
If you suspect the game may be malfunctioning, the following steps should be taken
before you make a service request.
(1) Check to see that the circuit breaker is properly set.
(2) The power supply should be set to either 110 or 220 Volts AC. However, when some
other equipment (air conditioner, multiple pinball games, air compressors, etc.) are
connected to the same power supply, the voltage may change beyond this range and
cause game trouble or improper operation.
(3) When the game does not work with the power turned on, turn the power off, wait ten
seconds, then turn the power back on. This may restart the game. If it still does not
work, inspect the fuses.
(4) When the game PCB, the Guns, the Steering Assembly, the Gas Pedal Assembly, or
the Potentiometers are replaced, it is necessary to make initialization adjustments to
play normal games. Make appropriate adjustments referring to sections 5-5 and 5-6.
(5) Check all wiring connections as malfunctions can be caused by loose connections.
(6) Foreign substances or dust on the game PCB or on the monitor PCB, may cause
malfunctions or improper operation. Check that the PCBs arc clean.
(7) When you make electrical checks, use the wiring diagrams for reference.
* If the above suggestions are not applicable, or no improvement is observed, contact
your disuibutor or the service office printed on the back cover of this manual.
* DO NOT ATTEMPT TO REPAIR THE GAME PCB YOURSELF. Instead,
please return the board to your distributor for any repairs. The PCB contains
sensitive chips that could be destroyed even by the internal voltage of a multi-
meter.
* When sending parts to be repaired, make sure to pack them firmly with a complete
explanation of the problem. When sending PCBs, package them in anti-static
foam or bubble wrap, and pack them in cardboard boxes to protect against impact
damage during shipment. To ship monitors, pack them in wooden frames so that
CRTs and PCBs are protected against excess load.
