FIRE AND EXPLOSION HAZARD
A Fire and explosion hazard exists
any time you spray or flush flammable fluids.
To help prevent fire or explosion when
spraying flammable fluids
D Be sure sprayer is adequately grounded
through electrical outlet as follows:
– Use only grounded electrical outlets.
– Use only 3-wire extension cords.
– Make sure ground prongs are intact
on sprayer and extension cords.
D Motor in this sprayer is a source of
sparks. Keep sprayer in well-ventilated
area, at least 20 feet (6 meters) away
from gun when spraying or flushing.
D Do not use plastic drop cloths when
spraying or flushing flammable fluids.
D 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.
D Tape wall switches to prevent them from being turned
off or on.
D Do not smoke in spray area.
D Use only M
D Use outdoors or in a well-ventilated area.
EQUIPMENT MISUSE HAZARD
Do not use 1,1,1–trichloroethane, methylene
chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents
in pressurized aluminum equipment such as
this sprayer and gun. Such use could result in
chemical reaction and possible explosion.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause
serious injury or death if splashed in eyes
eyes or on skin, inhaled, or swallowed.
To help prevent injury or death from
toxic fluids
D Know specific hazards of fluid you are using; store
hazardous fluid in approved tub; dispose of
hazardous fluid according to all local, state, and
national guidelines.
D Always wear protective eyewear, gloves, clothing, and
respirator as recommended by fluid and solvent
manufacturer.
AGNUM or Graco airless paint hoses.
FLUID INJECTION HAZARD
If high-pressure fluid pierces skin,
the injury might look like “just a cut”
but is a serious wound. Get
immediate medical attention.
To help prevent injection
D Always put trigger safety lever in SAFETY
ON position when not spraying.
D Always shut off power and relieve pressure
when you stop spraying and before you
service or clean sprayer, remove parts, or
repair leaks. See Pressure Relief
Procedure below.
D Do not allow children to use this equipment.
D Keep clear of tip, and never point gun at
yourself or anyone else.
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.
FLUID SPLASHBACK HAZARD
Wear protective eyewear at all times.
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. See Installing Tip &
Guard in enclosed Operator’s Quick Guide.
PRESSURIZED EQUIPMENT HAZARD
M
AGNUM sprayers are capable of
producing up to 3000 psi (21 MPa, 207 bar)
maximum working pressure. 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 of fluid. Correct fault before you resume spraying.
NOTE: Inadequate flushing and/or dried paint in drain
system may prevent proper overpressure relief.
ELECTRIC SHOCK HAZARD
Gun, hose, and sprayer are grounded
through electrical cord of sprayer.
To help prevent electric shock
D Use only grounded electrical outlets.
D Only use 3-wire extension cords.
D Make sure ground prongs are intact on sprayer and
extension cords.
D Keep electrical connections and inside of shroud dry.
