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.
