Check everything in the troubleshooting tables before you disassemble any equipment.

Paint Guns and Bead Guns

PROBLEM

CAUSE

SOLUTION

Paint guns not spraying

Clogged tips

Clean tips.

Fuse (20A) is blown

Check 20A fuse between engine and

solenoid air valve connector.

Gun arm safety sensor

1. Start RoadLazer engine.

NOTE:

With gun arm away from sensor

(145), sensor yellow LED light is ON. With

gun arm stowed, light is OFF. Sensor green

LED ON indicates sensor has power.

2. Replace sensor if necessary. (Be sure to

plug new sensor into correct wiring socket).

Air compressor and unloader valve

1. Turn silver toggle switch at top of unloader

(41) to horizontal.

NOTE:

Unloader bypasses air when system

pressure reaches approximately 100 psi

(7 bar).

2. Turn off bead tank air valve (47) to isolate

system.

3. If no leaks, check paint gun actuation airline

Paint gun actuation airline

1. Remove paint gun actuation airline (338)

from paint gun

2. Trigger skipline controller

3. If air flows from airline, repair paint gun.

Manual 308613. If air does not flow check

solenoid valves.

Solenoid valves

1. Remove solenoid valve cover (319)

2. Check for broken wiring or damaged plug

(See

Schematics

on pages 49 to 51.)

3. Check for 12V DC between red wire and

ground.

Note: If all solenoids fail, there is a broken

wire; replace wire. If some solenoid operate

and some fail; replace failed solenoids.

Programmable Skipline Controller

1. Inspect wiring and plugs for damage.

2. Replace any damaged wiring or plugs.

Manual 3A1215.
