309323E

3600 psi (24.8 MPa, 248 bar) Maximum Fluid Inlet Pressure

The best operating pressure is the lowest pressure that provides

an even paint supply to the roller and typically does not exceed 300 psi (2.1 MPa, 21 bar).

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.

Warnings and Cautions

Installation

WARNING

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 solvents 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.

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.

SKIN 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 surgical treatment.

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.

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.

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. Turn prime/spray valve to the PRIME 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/spray valve in PRIME position until you paint again.

Operation

1. Follow pump priming instructions using lowest

pressure setting at which pump primes.

2. Turn prime/spray valve to SPRAY position.

3. Disengage gun safety latch, trigger the gun, and

roll the surface until paint comes to roller. NOTE: Trigger the gun briefly only when you need

more paint. Determine how often you must trigger the gun to maintain an even paint supply to the roller.

4. Increase pump pressure only if triggering gun

cannot supply enough paint for your rolling speed.

See Pressure Relief

Procedure on page 2.

5. 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 Cleaning on page 3.
