The RailKing Operating Car Wash is sure to add fun

and authenticity to any layout. With moving car and

figures, digital conversations, and even a smoke unit to

replicate the mist inside the car wash, this operating

building really comes alive.

As complex as the car wash seems, it is easy to run and

maintain when you follow the easy operating

instructions inside.

Operating

The RailKing Car Wash is made up of three components: the car wash

building and base, the car, and the activation button. Before you place the

car wash on the layout, you must wire the car wash to the activation button

and power source. In order to connect power to each component, the six

(6) enclosed wires must be connected to the wiring posts located on the

underside of the car wash and the activation button. Wires from ports A-C

control the car operation. Wires from ports D-E control the lights. Follow

the diagram (Fig 1) shown to make the correct connections.

Priming the Smoke Unit:

It is essential that you either prime the smoke

unit or turn the smoke unit off before you operate the car wash. Failure to do so could

result in a charred wick and damaged mechanisms.

1. To prime the unit, remove the cap of the smoke stack on top of the car wash (Fig. 2)

and add 15-20 drops of ProtoSmoke (included is a small pipette of ProtoSmoke fluid),

Seuthe, LGB, or LVTS smoke fluid through the hole. Then gently blow into the hole to

eliminate bubbles. Do not overfill the unit, as that can cause the fluid to leak out and

coat other interior components. When smoke output begins to diminish, add another

10-15 drops of fluid.

2. If you choose not to prime the smoke unit, turn it off using the switch located on the

bottom of the car wash base, next to the wiring post (Fig 1).

The smoke unit is essentially a small heating element and

wick. The wick soaks up a mineral oil-based fluid, which is then "cooked" by the

heating element to emit a harmless smoke. It is forced into the car wash by a small

electric fan that runs at a constant speed.

Fig 2. Smoke Stack Cap

Failure to keep enough oil on the wick while

operating the car wash can cause the wick to

become black, hard, and un-absorbent around

the heating element. See page 7 to check the

condition of the wick.

Priming the Smoke Unit

3. When storing the car wash for long periods of time,

you should add at least 15 drops of fluid to prevent the

wick from drying out. After removing it from storage,

add another 25 drops of fluid, letting the wick soak for

15 minutes prior to operation.

Operating Instructions: Before operating the car wash, you must first place

the two drying figures and the car on the base. Insert the tabs on the bottoms

of the drying figures into their slots in the following order: The man wearing

the white shirt goes in the slot nearest the car wash exit, and the man in the

gray shirt goes in the slot farther from the car wash exit. Place the car on the

tab in its track. See the diagram on page 5 for the figure and car placement.

Once the car wash is wired to receive at least a14-20 volt power supply from

the transformer and the transformer is turned on, simply press the activation

button to begin the car wash sequence.

The car starts, pulls forward to the window to talk to the attendant and pay for

the car wash, and pulls around to the car wash doors. The doors open to

allow the car to enter. The car spends about 15 seconds in the car wash,

during which time the smoke unit will supply car wash "mist" and the "Rinse"

light will activate. The car pulls out through the rollers and stops at the red

light for a dry. Finally it pulls around to the two figures who buff the car, then

pulls away. The car wash doors shut after the car has cleared the car wash.

The car wash completes all of these actions by itself, with just the initial press

of the activation button.

The motion and sound can be stopped at any time by turning the power off or

by pressing the transformer's "Direction" button. Once the power is returned,

the car will return to its starting position without sound effects.

the replacement bulb in and twist it clockwise.

To access and change the other lights: Remove the clear shield over the

rollers. Remove the four (4) recessed screws from the bottom of the car

wash, turn it back over, and tilt the car wash housing to reveal the lights.

You will also need to unplug some of the connections from the PCB to

remove the housing. Refer to the PCB Diagram on page 8.
