Warnings and Cautions
Preventing Corrosion Damage and Freezing
CAUTION
Never leave water in the pump, gun, or pressure roller. Doing
so could cause corrosion and damage from freezing. For
storage, flush the system with Graco Pump Armort or
mineral spirits/paint thinner. See Flushing on page 3.
Installation
Assemble the pressure roller as shown in the Parts
Drawing on page 3.
Pressure Relief Procedure
WARNING
To help prevent injection injuries,
follow this procedure whenever
you stop painting.
psi/MPa/bar
1. Put gun trigger safety in SAFETY ON position.
2. Shut off power to pump.
3. Put pump prime/drain valve (required for pressure
relief) in DRAIN position to relieve pressure in
system.
4. Put gun trigger safety in SAFETY OFF position,
and trigger gun to relieve any pressure in hose.
5. Put gun trigger safety in SAFETY ON position, and
keep pump prime/drain valve in DRAIN position
until you paint again.
Operation
1. Follow pump priming instructions using lowest
pressure setting at which pump primes.
2. Put pump prime/drain valve in position that
delivers fluid to hose.
3. Disengage gun safety latch, and trigger gun briefly
until paint comes to roller.
4. Experiment with triggering gun and rolling paint.
NOTE: Trigger the gun briefly when you need
more paint. Determine how often you must trigger
the gun to maintain an even paint supply to the
roller.
5. Increase pump pressure only if triggering gun
cannot supply enough paint for your rolling speed.
See Pressure Relief
Procedure on page 2.
6. Whenever you stop painting, relieve the
pressure, and elevate roller end of extension tube
to prevent paint from draining out.
Flush the pump, gun, and pressure roller immediately
after each use to prevent paint from drying in the
pressure roller and damaging it. See Flushing on
page 3.
EQUIPMENT MISUSE HAZARD
Misuse can cause the equipment to rupture or
malfunction and result in serious injury.
To help prevent injury
D Do not modify the extension tube or roller
frame or use parts not designed for this
equipment.
D Do not use 1,1,1–trichloroethane, methylene
chloride, other halogenated hydrocarbon sol-
vents or fluids containing such solvents in this or
any other pressurized aluminum equipment.
Such use could result in a chemical reaction,
with the possibility of explosion.
ELECTROCUTION HAZARD
Failure to observe the electrical hazards described
below could result in serious injury, including burns
or electrocution.
To help prevent harmful electrical shock
D Avoid contact with power lines.
D Follow all grounding instructions in your
separate pump and gun instruction manual,
and comply with all local, state, and national
fire, electrical, and safety regulations.
D Use only Graco paint hoses.
FLUID INJECTION HAZARD
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.
To help prevent injection
D Keep your hands and body away form the
roller frame when flushing. High pressure
fluid emitted from the holes in the frame
could cause an injection injury.
D Always relieve pressure before you check or
repair leaks and when you turn off pump or stop
painting.
D Never use components rated less than system
Maximum Working Pressure.
INSTRUCTIONS
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open
flames or sparks can cause a hazardous
condition and result in a fire or explosion and
serious injury.
To help prevent injury from fire or explosion
D Provide fresh air ventilation to avoid the
buildup of flammable fumes from flushing
fluids or the coating being applied.
D Keep the application area free of debris,
including solvent, rags, and gasoline.
