Do not attempt to complete this work alone, a minimum of 2 people are required.
·
· Only QUALIFIED SERVICE PERSONNEL should carry out assembly.
When carrying out the assembly work, follow the procedure in the following sequence:
STEP 1 INSTALLING THE BILLBOARD
STEP 2 INSTALLING THE FLOOR
STEP 3 SECURING IN PLACE (LEG ADJUSTMENT)
STEP 4 FITTING SEAT
STEP 5 CONNECTION TO THE POWER SUPPLY
STEP 6 ASSEMBLY CHECK
Note that the parts contained within the installation kit are required for the assembly work.
The following tools will be required when installing this machine:
13
3.7.1. INSTALLING THE BILLBOARD
· To perform work safely, use a secure and stable step to improve access to the
top of the cabinet. Working without using a step may cause accidents.
Only QUALIFIED SERVICE PERSONNEL should carry out this operation.
·
1. Insert ASSY BILLBOARD to the top part of the cabinet
2. Secure with the two Tamperproof screws (Part No.
008-T00412-0B, supplied with Accessory kit)
14
INSTALLING THE FLOOR
Ensure all connections are secure - poor connections can cause electric shock or
·
short circuit.
· Take care not to damage wiring during installation, as this can cause electric
shock or short circuit.
15
Slightly lower the 2 Adjusters on the cabinet and install JOINT BRACKET L & R by inserting from
the rear, and secure to ASSY FLOOR using hexagon bolts as shown.
After lowering the Adjusters fully downward, tighten both Adjuster’s lock nuts fully upward.
16
3.7.2. SECURING IN PLACE (LEG ADJUSTER ADJUSTMENT)

·
machine may move and cause injury. This operation requires 2 people.
· Only QUALIFIED SERVICE PERSONNEL should carry out this operation.
This machine has four castors and two leg adjusters on the main cabinet, and a further two level adjusters
on the rear of the floor. When the installation position is decided, unscrew the leg adjusters so that they
raise both front castors 7mm from the floor. Make sure the machine is level.
1. Move the product into the installed position.
2. Unscrew the adjusters until they are in contact
the floor, and use a wrench to turn them further
until the front castors are raised approximately
7mm above the floor.
3. Tighten the locknut on the leg adjusters upwards
to lock the legs in position.
17
If this product is installed on irregular surfaces, use the two Level Adjusters on the bottom of the FLOOR to
ensure the product is level.

3.7.3. FITTING THE SEAT
3.7.3.1. Introduction:
This kit facilitates a lean-on REST for application to ROUTE 66 Standard. This REST allows pressure to be
taken off the left leg, which increases the length of time that a player may play the game without suffering
from fatigue.

3.7.3.3. Installation instructions:
A condition of fitting this REST is that the machine is fully fitted with items CTA-0001 &
·
CTA-0002 (JOINT BRKT L & R) as described in the 18 WHEELER Manual. Non-fitment
of these brackets may lead to injury, as there will be nothing to secure the floor to the
main cabinet. The REST relies on the floor being firmly secured to the main cabinet in
order to support the weight of the player when resting against the machine.
The REST utilises the weight of the main cabinet to prevent tipping. It is important that
·
this REST is used only to take the weight off the left leg. Sega accepts no responsibility
for injury arising due to inappropriate usage of the REST.
1. Fix the CTA-5001UK & CTA-5002UK SEAT FRAMES to the FLOOR ASSEMBLY (CTH-1500UK) using
the 8-off M8 bolts and washers provided as shown.
2. Fix the CTA-5003UK & CTA-5004UK SEAT FRAME COVERS to the SEAT FRAMES using the 10-off
M4 tamperproof machine screws provided as shown.
3. Fix the CTA-5005UK SEAT BENCH PTR between the SEAT FRAMES using the 8-off M6 bolts and
washers provided as shown. Loosely fit these bolts (top ones first) before tightening.

3.9. MOVING THE MACHINE
· When moving the machine, be sure to remove the plug from the power supply. Moving
the machine with the plug inserted can cause the power cord to be damaged, resulting
in a fire or electric shock.
When moving the machine, retract the leg adjusters fully and ensure the casters make
·
contact with the floor. During movement pay careful attention so that the casters or leg
adjusters do not damage any other cabling laid on the floor. Such damage could result
in a fire or electric shock.
Do not push the upper part of the cabinet. Failure to observe this can cause the
·
cabinet to fall forwards and result in accidents.
When transporting the machine, be sure to hold the catch portion on the rear of the
·
cabinet with the castors making contact with the surface as shown below. Inclining the
machine by holding portions other than the catch or moving the cabinet without
retracting the adjusters can damage the cabinet and/or the floor surface.
Do not push the Billboard. Failure to observe this may damage the installation portions
·
and may cause unexpected accidents.
Only QUALIFIED SERVICE PERSONNEL should carry out this operation.
·
27
(Remove SEAT ASSY before moving)
3.10. CONTROL PANEL (HANDLE MECHA.) - ‘HAPP’ TYPE
Before starting work, ensure that the cabinet is isolated from the mains by
·
switching off and removing the IEC mains lead from the wall outlet.
· Be careful not to damage wiring. Damaged wiring can cause electric shock and
short circuits.
When closing the Control Panel be very careful to avoid trapping fingers or hands.
·
Only QUALIFIED SERVICE PERSONNEL should carry out this procedure.
·
3.10.1. REPLACING VOLUME
If the steering operability becomes poor, and adjusting the VOLUME SETTING in the TEST MODE in
ineffective, the cause may be the failure of the Volume Gear to mesh and/or the Volume Potentiometer
malfunctioning.
When the Steering Wheel is rotated fully left or right, if the Volume shaft is rotating within the movable
range, the Volume is not feared to be damaged. Use the procedure described herein to position the
steering VR such that the correct centre value (refer to Section 5.3.5) is displayed when the Steering Wheel
is at rest.
1. Power OFF the machine and
remove the IEC lead from the
wall outlet.
2. Remove the three tamperproof
screws and open the Control
Panel.
28
1. Loosen the two screws and adjust
the gear mesh by moving the VR
Bracket.
2. Adjust to an appropriate setting by
securing the steering wheel in the
straight ahead position.
3. After adjustment, check the volume
setting as described in Section 5.3.5.
If necessary, repeat steps 3 & 4 until
the volume value is within allowable
limits (±3H)
HOW TO REPLACE
1. Disconnect the Volume Connector.
2. Take out the two screws and remove the Volume together with the VR Bracket.
3. After replacing the Volume, engage the gears at the angle shown and fix the VR Bracket.
Close the Control Panel and replace the three tamperproof screws before turning power ON and setting the
Volume value in the TEST MODE.
