3600 psi (24.8 MPa, 248 bar) Maximum Fluid Inlet Pressure/* / Pression maximale d’admission de fluide* PresIón de entrada de fluido máxima*

*Use the lowest pressure that provides an even paint supply to the roller; typically less than 300 psi (2.1 MPa, 21 bar).

*Employez la plus basse pression qui fournit une offre égale de peinture au

rouleau ; en général moins de 300 psi (2.1 MPa, 21 bar).

* Utilice la presión más baja que proporciona una fuente uniforme de la pintura al rodillo; típicamente menos de 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.

ATTENTION

Ne jamais laisser d’eau dans la pompe, le pistolet ou le rouleau à peinture sous pression. Cela pourrait causer de la corrosion et des dommages dus à la congélation. Pour l’entreposage, vidanger le système avec du Pump Armort de Graco, de l’essence minérale ou du solvant à peinture.

PRECAUCION

Nunca deje agua en la bomba, en la pistola ni en el rodillo a presión. Esto podría provocar corrosión y daños por congelamiento. Para su almacenamiento, lave el sistema con Pump Armort de Graco o solución alcohólica mineral o disolvente de pinturas.

Warnings

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause the equipment to rupture or malfunction and result in serious injury.

To help prevent injury

DDo not modify the extension tube or roller frame or use parts not designed for this equipment.

DDo 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.

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 surgical treatment.

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 MAGNUM or Graco paint hoses.

Additional Roller Covers

The following MAGNUM pressure roller covers are available at your local distributor:

243063 9 in. (23 cm); 1/2 in. (13 mm) nap

243064 9 in. (23 cm); 3/4 in. (19 mm) nap

243065 9 in. (23 cm); 1-1/4 in. (32 mm) nap

Installation

Assemble the pressure roller as shown in the Parts Drawing on page 3. Attach pressure roller assembly to spray gun.

Pressure Relief Procedure

WARNING

To help prevent injection injuries, follow this procedure whenever

psi/MPa/bar you stop painting.

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 2.

Cleaning

This is the procedure for flushing the pressure roller. The pump and gun you are using may have additional flushing steps, such as cleaning filters and screens. See the pump and gun flushing instructions.

NOTE: Leave the pressure roller attached to the gun for this procedure.

See Pressure Relief

Procedure on page 2.

1. Relieve the pressure.

2. Remove roller cover (19) and diffuser (23) from roller frame as follows (see Parts Drawing):

a.Using your thumb, press down on clip (5) to release end caps (2 &4), diffuser (23) and roller cover (19) into a pail.

b.Remove roller cover (19) from diffuser (23).

c.Pull end caps (2 & 4) off diffuser (23). Disassemble.

3. Clean roller cover (19), caps (2 & 4) and diffuser (19) with water or a compatible fluid for oil–based materials.

4. Place roller frame (1) in paint pail. Be sure the holes in roller frame (1) are facing inside the paint pail.

5. Prime pump with water or flushing fluid for oil–based materials. Use the lowest pump priming pressure setting.

6. Turn prime/spray valve to SPRAY.

NOTE: Perform Step 7 at the lowest pressure possible.

7. Trigger gun until flushing fluid begins to dilute the paint.

8. Place roller frame (1) in another bucket and continue flushing until fluid coming out of the roller frame (1) is clear.

9. Shut off the pump. Turn prime/spray valve to PRIME.

Storage

If you are going to store the airless equipment for an extended period of time after flushing with water-base fluid, flush again with Graco Pump Armor or mineral spirits/paint thinner. Leave the fluid in the system during storage.
