Rev. D

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.

INSTRUCTIONS

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 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.

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.

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 MAGNUM or Graco paint hoses.

Pressure Relief Procedure

WARNING

To help prevent injection injuries,
follow this procedure whenever
you stop painting.

psi/MPa/bar

1. Engage gun trigger safety latch.

2. Shut off power to pump.

3. Turn prime/spray valve to the PRIME to relieve

pressure in system.

4. Remove gun trigger safety latch. Trigger gun to
relieve any pressure in hose.

5. Engage gun trigger safety latch. Keep pump
prime/spray valve in PRIME position until you paint
again.

309511 3

Operation

1. Follow pump priming instructions prior to

assembling roller.

2. Do not put tip and guard on spray gun.

3. Turn prime/spray valve to SPRAY.

4. Turn pressure control to lowest setting or roller

symbol. Fig. 1.

Fig. 1

5. Remove gun trigger safety latch. Trigger the gun

once until paint comes out of gun. Release
trigger.

6. Engage gun trigger safety latch.

7. Assemble the pressure roller as shown in the Parts

Drawing, page 7. Make sure the gasket (6) is in
place in bottom of roller frame as shown.

8. Attach pressure roller assembly to spray gun.

10. Remove gun trigger safety latch. Trigger gun.

Roll surface.

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.

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).

11. Increase pump pressure only if triggering gun
cannot supply enough paint for your rolling speed.

Pressure Relief
Procedure, page 3.

12. 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. (Cleaning, page 6).

9. Rest roller on flat surface and align gun with roller.
Tighten nut with wrench while keeping gun and
roller aligned as pictured below.

Rolling Techniques

1. Rolling vertically, roll out the letter “M”. (Fig. 2.)

Fig. 2

2. Cross roll, horizontally, to spread paint. (Fig. 3.)

Fig. 3

3. Finish with light, vertical strokes until the entire

area has been covered, evenly. (Fig. 4.)

Fig. 4

Ceilings, Walls, and Woodwork

1. Ceilings: Using a paint brush, apply a starting

row of paint approximately the width of your paint
brush where the walls and ceiling meet. (Fig. 5.)

Fig. 5

2. With the roller, apply paint to the ceiling, working

the short way of the room and applying as wide a
strip as possible. (Fig. 6.)

1. Woodwork & Walls: Using a brush, paint
woodwork first. Apply a starting row of paint
approximately the width of the paint brush around
the woodwork and where the walls meet the
ceiling. (Fig. 7.)

Fig. 7

2. With the roller, apply paint to the walls, following

the Roller Techniques described above. (Fig. 8.)

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.

Pressure Relief
Procedure, page 3.

1. Relieve the pressure.

2. Remove roller cover (7) and diffuser (4) from roller

frame as follows (Parts Drawing, page 7):

a. Using your thumb, press down on clip (5) to

release end caps (2 & 3), diffuser (4) and roller
cover (7) into a pail.

b. Remove roller cover (7) from diffuser (4).

c. Pull end caps (2 & 3) off diffuser (4).

Disassemble.

3. Clean roller cover (7), caps (2 &3) and diffuser (7)
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.
