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.
INSTRUCTIONS
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 Graco paint hoses.

Pressure Relief Procedure
WARNING
psi/MPa/bar
To help prevent injection injuries, follow this procedure whenever 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 3.
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.

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.
