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. 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.
If you suspect that the frame or hose is completely
clogged or that pressure has not been fully relieved
after following the steps above, VERY SLOWLY
loosen the tip retaining nut or hose end coupling and
relieve pressure gradually, then loosen completely.
Now clear the frame or hose obstruction.

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 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.
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.
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.
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
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.

appropriate warnings and instructions for safe op-
eration of this roller frame.
Gasket (12) must be in place before installing
frame (1). If gasket is not in place there is a poten-
tial injection hazard which could result in serious
injury.
1. Follow Pressure Relief Procedure on page 1.
2. Prime pump.
3. Install roller frame.
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 1.
1. Relieve the pressure.
2. Remove roller cover and diffuser (3) from roller
frame (1) as follows (see Parts Drawing):
a. Using your thumb, press down on clip (5) to
release end caps (2 &4), diffuser (3) and roller
cover into a pail.
b. Remove roller cover from diffuser (3).
c. Pull end caps (2 & 4) off diffuser (3).
3. Clean roller cover, caps (2 & 4) and diffuser (3)
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 pos-
sible.
7. Trigger gun until flushing fluid begins to dilute the
paint.
8. Place roller frame (1) in another bucket and contin-
