WARNING

Fire and explosion hazard: Solvent and paint fumes can ignite or explode.

To help prevent a fire and explosion:

D

Use only in an extremely well ventilated area.

D

Eliminate all ignition sources; such as pilot lights, cigarettes and static arcs from plastic drop cloths. Do not plug or unplug power cords or turn lights on or off in spray area.

D

Ground Sprayer, object being sprayed, paint and solvent pails.

D Hold gun firmly to side of grounded pail when triggering into pail.

D

Use only conductive airless paint hose.

D Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use could result in a chemical reaction, with the possibility of explosion.

D

To reduce risk of electric shock, use grounded outlet only. Shut OFF and unplug when repairing.

Fluid injection and high pressure hazard: High pressure spray or leaks can inject fluid into the body.

To help prevent injection, always:

D Engage trigger safety latch when not spraying.

D

Keep clear of nozzle and leaks.

D

Never spray without a tip guard.

D

Do PRESSURE RELIEF if you stop spraying or begin servicing sprayer.

D

Do not use components rated less than sprayer Maximum

Working Pressure.

D

Never allow children to use this unit.

If high pressure fluid pierces your skin, the injury might look like “just a cut”. But it is a serious wound! Get immediate medical attention.

PRESSURE RELIEF – Do this when cleaning, repairing or shuting down sprayer

1. Turn pressure to lowest setting.

Turn power OFF .

Unplug sprayer.

2. Trigger gun to relieve pressure.

3. Put drain tube in pail .

Turn prime valve down.

D TIMER : Duration of AutoClean flush cycle

NOTE: The SMARTCONTROL button is not active if pressure is above 200 psi

Error Codes

Sprayer stops and displays error code if fault occurs

After fault has been corrected or Timer reaches zero, turn sprayer OFF and then

ON to reset SMARTCONTROL
