WARNING

Fire and explosion hazard: Solvent and paint fumes can

ignite or explode.

To help prevent a fire and explosion:

DUse only in an extremely well ventilated area.
DEliminate 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.

DGround Sprayer, object being sprayed, paint and solvent

pails.

DHold gun firmly to side of grounded pail when triggering into

pail.

DUse only conductive airless paint hose.
DDo 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.

DTo 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:

DEngage trigger safety latch when not spraying.
DKeep clear of nozzle and leaks.
DNever spray without a tip guard.
DDo PRESSURE RELIEF if you stop spraying or begin

servicing sprayer.

DDo not use components rated less than sprayer Maximum

Working Pressure.

DNever 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.

Spray Test Pattern

heavy
edges

1. Trigger gun and spray test pattern.
Slowly adjust pressure to eliminate
heavy edges. Use smaller tip size if
pressure adjustment can not eliminate
heavy edges.

2. Hold gun perpendicular, 10–12 in.
(25–30 cm) from surface. Spray back
and forth. Use strokes overlapped by
50%. Start gun movement before trig­gering gun and release trigger before
stopping gun movement.

Clearing Tip Clogs

10 309273

1. Release trigger, put trigger safety ON.
Rotate SwitchTip. Take trigger safety
OFF and trigger gun to clear the clog.

Never point gun towards your hand
or into a rag!

2. Put trigger safety ON, return SwitchTip
to original position, take trigger safety
OFF and continue spraying.

Cleanup

Perform AutoClean procedure (Manual 309278) or follow conventional
flushing/cleaning procedure that follows:

1. Turn power OFF.

2. Turn pressure to lowest setting.
Trigger gun to relieve pressure.

3. Turn prime valve down.

4. Remove filter assembly and
