Warnings and Cautions

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	INSTRUCTIONS
frame or use parts not designed for this
equipment.

DDo 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.

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

DProvide fresh air ventilation to avoid the buildup of flammable fumes from flushing fluids or the coating being applied.

DKeep the application area free of debris, including solvent, rags, and gasoline.

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

DKeep 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.

DAlways relieve pressure before you check or repair leaks and when you turn off pump or stop painting.

DNever 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

DAvoid contact with power lines.

DFollow all grounding instructions in your separate pump and gun instruction manual, and comply with all local, state, and national fire, electrical, and safety regulations.

DUse only Graco paint hoses.

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.
