1. Turn pressure to lowest setting.
Turn power OFF.
Unplug sprayer.
2. Trigger gun to relieve pressure.

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.

edges
Clearing Tip Clogs
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 trig-
gering gun and release trigger before
stopping gun movement.
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.
