Operation  
5. Perform Pressure Relief Procedure.  
Installation  
Assemble the pressure roller as shown in the Parts  
Drawing on page 4. Attach pressure roller assembly to  
spray gun.  
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  
Pressure Relief Procedure  
Cleaning  
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 Pro-  
cedure when you stop spraying and before cleaning,  
checking, or servicing the equipment.  
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. Engage gun trigger lock.  
2. Shut off power to pump.  
1. Perform Pressure Relief Procedure.  
2. Remove roller cover (19) and diffuser (23) from  
roller frame as follows (see Parts Drawing):  
3. Turn prime/spray valve to the PRIME position to  
relieve pressure in system.  
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. 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.  
b. Remove roller cover (19) from diffuser (23).  
c. Pull end caps (2 & 4) off diffuser (23).  
Disassemble.  
6. If you suspect the spray tip or hose is clogged or  
that pressure has not been fully relieved after follow-  
ing 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.  
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.  
5. Prime pump with water or flushing fluid for  
oil--based materials. Use the lowest pump priming  
pressure setting.  
Operation  
1. Follow pump priming instructions using lowest pres-  
sure setting at which pump primes. NOTE: Do not  
exceed minimum pressure required to supply paint  
to the roller.  
6. Turn prime/spray valve to SPRAY.  
NOTE: Perform Step 7 at the lowest pressure  
possible.  
2. Turn prime/spray valve to SPRAY position.  
7. Trigger gun until flushing fluid begins to dilute the  
paint.  
3. Disengage gun safety latch, trigger the gun, and roll  
the surface until paint comes to roller.  
8. Place roller frame (1) in another bucket and con-  
tinue flushing until fluid coming out of the roller  
frame (1) is clear.  
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.  
9. Shut off the pump. Turn prime/spray valve to  
PRIME.  
4. Increase pump pressure only if triggering gun can-  
not supply enough paint for your rolling speed.
