Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury. To help prevent injury:
•
Do not modify the extension tube or roller frame or use parts not designed for this equipment.
•
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:
•
Provide fresh air ventilation to avoid the buildup of flammable fumes from flushing fluids or the coating being
applied.
•
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
surgical treatment. To help prevent injection:
•
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.
•
Always relieve pressure before you check or repair leaks and when you turn off pump or stop painting.
•
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
•
Avoid contact with power lines.
•
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.
•
Use only MAGNUM or Graco paint hoses.
Additional Roller Covers
The following MAGNUM pressure roller covers are
available at your local distributor:

Operation
Installation
Assemble the pressure roller as shown in the Parts
Drawing on page 4. Attach pressure roller assembly to
spray gun.
Pressure Relief Procedure
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning,
checking, or servicing the equipment.
1. Engage gun trigger lock.
2. Shut off power to pump.
3. Turn prime/spray valve to the PRIME position to
relieve pressure in system.
4. Disengage gun trigger safety, and trigger gun to
relieve any pressure in hose.
5. Engage gun trigger safety, and keep pump
prime/spray valve in PRIME position until you paint
again.
6. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
5. Perform Pressure Relief Procedure.
6. Whenever you stop painting, relieve the pressure,
and elevate roller end of extension tube to prevent
paint from draining out.
NOTE: 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
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.
1. Perform Pressure Relief Procedure.
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--base
materials.
4. Place roller frame (1) in paint pail. Be sure the holes
in roller frame (1) are facing inside the paint pail.
Operation
1. Follow pump priming instructions using lowest pressure setting at which pump primes. NOTE: Do not
exceed minimum pressure required to supply paint
to the roller.
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 in short bursts 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.
332981A 3
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
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.
