before performing work by touching the interior parts of the product.
Be careful so as not to damage wirings. Damaged wiring can cause an electric
shock or short circuit accident.
Do not touch places other than those specified. Touching places not specified can
cause an electric shock or short circuit accident.

Loosen the 2 screws which secure the V.R.
Plate to move the V.R. Plate.
Move the V.R. Plate to disengage ADJUST
GEAR mesh and move the V.R. shaft and
ensure that when force is not exerted on the
pedal, the cut face of the Volume Shaft faces in
the direction shown.
Have the gears meshed and tighten the 2
screws. At this time, tighten gear backlash.
Carefully move pedal fully within the movable
range and check if the Volume range is
exceeded.
After finishing adjustments, be sure to perform
Volume Setting in Test Mode.1

Be sure to use the designated grease. Using undesignated grease can cause parts
damage.
Do not apply greasing to places other than those specified. Greasing to undesignated
places can cause malfunctioning and the quanlitative deterioration of parts.
Once every three months, apply greasing to the following places.
For Greasing use Grease Mate (P.No. 090-0066).9 - 2 GREASING

The coin selector should be cleaned
once every 3 months. When cleaning,
follow the procedure below:
Turn the power for the machine OFF.
Open the coin chute door.
Open the gate and dust off by using a
soft brush (made of wool, etc.).
Remove and cleen smears by using a
soft cloth dipped in water or diluted
chemical detergent and then squeezed
dry.
Remove the CRADLE.
When removing the retaining ring(E-
ring), be very careful so as not to bend
the shaft.
Remove stain from the shaft and pillow
portions by wiping off with a soft cloth,
etc.
After wiping as per #5 above, further
apply a dry cloth, etc. to cause the coin
selector to dry completely.
Once a month, when performing the COIN SW
TEST, simultaneously check the following:
Does the Coin Meter count satisfactorily?
Does the coin drop into the Cashbox correctly?
Is the coin rejected when inserted while keeping
the REJECT BUTTON is pressed down?If the coin is not rejected when the REJECT BUTTON is pressed, open the coin chute door
and open the selector gate. After removing the jammed coin, put a normal coin in and check
to see that the selector correctly functions.

NEEDED WIRING CONNECTIONS ARE CONVIENENTLY LOCATED INSIDE
THE GAME FOR THIS APPLICATION.
THE COIN DOOR CAN ACCCOMMODATE THE FOLLOWING
VALIDATORS:
HOLE POSITION#1                  Mars 2000 series
(FORWARD-MOST POSITION)
HOLE POSITION#2                  Mars 2000 series

*The back flange on the chute can be removed for hold position #4.
If the flange is not removed, it may interfere with the back of the
cabinent.
The frame and cashbox enclosure on this coindoor has been modified to accomodate a Mars 2000 series
upstacker. A 2000 series stacker can be added by simply removing the top two entry door and replacing it with a one
entry door with a cut-out for a stacker. This one entry door can be ordered through Coin Controls or one of Coin Controls
autherized distributors. The part number is 91-4000-01. The Mars stacker can be obtained through an autherized Mars
distibutor.

  11 . MONITOR
When performing such work as installing and removing the monitor, inserting and disconnect-
ing the external connectors to and from monitor, be sure to disconnect the power connector
(plug) before starting work. Proceeding the work without following this instruction can cause
electric shock of malfunctioning.
Using the monitor by converting it  without obtaining a prior permission is not allowed. SEGA
shall not be liable for any malfunctioning and accident caused by said conversion.
Primary side and secondary side Primary side and secondary sidePrimary side and secondary side Primary side and secondary side
Primary side and secondary side
The monitor’s circuit which is divided into the Primary
side and secondary side, is electrically isolated. Do
not touch the primary side and the secondary side
simultaneously. Failing to observe the instruction can
cause electric shock, and this is very dangerous.
When making monitor adjustments, use a non-
conductive driver and make adjustment without
touching any other part other than the Adjustment
V.R. and Knob. Also, be sure not to cause a short-
circuit to the Primary side and the Secondary side. If
short-circuited, it can cause electric shock or mal-
functioning, which is very dangerous.
High tension Voltage High tension VoltageHigh tension Voltage High tension Voltage
High tension Voltage
Some of the parts inside the monitor are subject to high-tension voltage in excess of 20,000
volts and very dangerous. Therefore, do not touch the monitor interior. Should soldering &
paper wastes, etc. be mixed in the monitor, turn the power off so as not to cause malfunc-
tioning or fire hazard.
Connecting the CRT and PCB Connecting the CRT and PCBConnecting the CRT and PCB Connecting the CRT and PCB
Connecting the CRT and PCB
For combining the CRT and PCB, use the specified part No. to maintain the status of adjust-
ments made at the factory. The anode of the CRT itself will be accumulitavly charged as time
elapses, generating high tension voltage which is very dangerous. The monitor should be used
with the Chassis, CRT and PCB assembled. When repair, etc. is required at the time of malfunc-
tioning, be sure to send it in an “as assembled” condition. If these are dissassembled, what’s
charged to said high tension voltage can be discharged, cuasing a very hazardous situation.
Therefore, under no circumstances should it be dissasembled.
Static Electricity Static ElectricityStatic Electricity Static Electricity
Static Electricity
Touching the CRT surface sometimes cuases you to slightly feel electricity. this is because the
CRT surfaces are subject to static and will not adversly affect the human body.
Installation and removal Installation and removalInstallation and removal Installation and removal
Installation and removal
Ensure that the Magnetizer Coil, FBT (Fly-Back Transformer), Anode Lead and Focus Lead are
not positioned close to the sheet metal work’s sharp edges, etc. and avoid damaging the
insulated portions so as no to cause an electric shock and malfunctioning. (For the name of
parts, refer to the above figures.)

For the purpose of static prevention,
special coating is applied to the CRT
face of this product. To protect the
coating, pay attention to the following
points. Damaging the coating film can
cause electric shock to the customers.
For the caution to be heeded  when
clearing, refer to the Section of Periodic
inspection Table.
Do not apply or rub with a hard item (a
rod with pointed edge, pen, etc.) to or
on C.R.T. surfaces.
Avoid applying stoickers, seals, etc. on
the C.R.T. face.
Do not remove aluminum foils from the
C.R.T. corners. Removing the aluminum
foils can cause static prevention effects
to be lowered.

12 . REPLACEMENT OF FLUORESCENT LAMP AND LAMPS
When performing the work, be sure to turn power off. Working
with power on can cause an electric shock or short circuit acci-
dent.
The Flourescent Lamp, when it gets hot, can cause burns. Be
very careful when replacing the Fluorescent Lamp.
To perform work safely and securely, be sure to prepare a step which is in a
secure and stable condition. Not using a step or using an unstable step can
cause a violent falling down accidents.
12 -1  REPLACEMENT OF FLUORESCENT LAMP
Take off the 3 screws which secure the Holder on the upper part of Billboard.
Take out the billboard from the cabinet and replace the fluorescent lamp (20W)
