WARNING
Fire, Explosion and Electrocution
Hazard
Improper grounding, poor air ventilation, open
flames, or sparks can cause a hazardous condi-
tion and result in fire, explosion, or electric shock.
To help prevent these hazards:
•Sprayer should be grounded through an elec-
trical outlet as follows:
- Only use grounded electrical outlets.
- Only use 3-wire extension cords.
- Grounded prongs must be intact on sprayer
and extension cords.
•Keep electrical connections and inside of
shroud dry.
•Avoid contact with power lines.
•Use outdoors or in well-ventilated area.
•Sprayer should be at least 6m (20 ft) from gun
when spraying or flushing.
•If there is any static sparking while using
equipment, stop spraying immediately.
Identify and correct the problem.
•Avoid all ignition sources such as pilot lights,
cigarettes and plastic drop cloths (static arc
hazard).
•Do not plug in or unplug power cords or turn
lights on or off in spray area.
•Only use Graco airless paint hoses.

WARNING
Pressurized Equipment Hazard
To avoid component rupture and injury, do not
operate sprayer with components rated less than
pressure of sprayer.
Sprayer is equipped with a pressure drain that
automatically relieves overpressure in the event of
a fault condition. This automatic pressure relief
may cause splashing fluid. Correct fault before
you resume spraying.
Inadequate flushing and/or dried paint in drain
system may prevent proper overpressure relief.
Toxic Fluid Hazard
Hazardous fluids or toxic fumes can cause serious
injury or death if splashed in eyes or on skin, swal-
lowed, or inhaled.
•Know specific hazards of fluid being used.
Read fluid manufacturer’s warnings.
•Wear appropriate protective clothing, gloves,
eyewear, and respirator.
•
•
Fluid Injection Hazard
If high-pressure fluid pierces skin, the injury might
look like “just a cut”but it is a serious wound. Get
immediate medical attention. To help prevent
injection:
•Always engage trigger safety when not spray-
ing.
•Always shut off power and relieve pressure
when you stop spraying, before you service or
clean sprayer, remove parts or repair leaks.
See Pressure Relief Procedure, page 9.
•Do not allow children to use this equipment.
•Keep clear of tip. Never point at yourself or
anyone else.

Fluid Splashback Hazard
To avoid splashing fluid when spraying into pail,
always aim at inside wall of pail. Make sure gun is
assembled with correct gasket for fluid being
sprayed.

WARNING
Recoil Hazard
Due to the high pressure fluid emitted, a strong
recoil action may occur when you trigger the
gun. If you are unprepared, your hand could be
forced back toward your body or you could lose
your balance and fall, resulting in serious injury.
Equipment Misuse Hazard
Equipment misuse can cause equipment to rup-
ture, malfunction, or start unexpectedly and
cause serious injury.
•Read all manuals, tags, and labels before
operating equipment.
•Only use equipment for its intended pur-
pose.
•Do not alter or modify equipment.
•Do not exceed maximum working pressure
of lowest rated system component.
•Do not modify extension tube or roller frame
or use parts not designed for this equipment
•Do not use 1,1,1-trichloroethane, methylene
chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents in
this or any other pressurized aluminum
equipment. Such use could result in a chem-
ical reaction, with the possibility of explosion.

Startup Hazard After Thermal
Overload
Motor has thermal overload switch to shut itself
down if overheated. To reduce risk of injury from
motor restarting unexpectedly when it cools,
always turn power switch OFF if motor shuts
down.
