a. Your new sprayer was tested at the factory with mineral

spirits. You must clean the system before spraying to
avoid contamination of the sprayed material.
If you are spraying a water based latex, flush with warm,
soapy water followed by a clean water rinse. If you are
using any other coating, flush with warm, soapy water
followed by a solvent. Check with the material
manufacturer for a compatible solvent. Place siphon
tube assembly into proper solvent or water.

b. Place waste container below bleed line.

c. Start engine or electric motor. Turn the pressure control

adjustment knob clockwise (increasing pressure) until
pump cycles evenly and solvent flows freely from bleed
line.

d. Close the pressure bleed valve by turning it clockwise.

This allows the system to pressurize. Hold the gun
trigger open, without spray tip attached, until the fluid
flows smoothly.

7. Repeat above starting procedure with paint material. Lock

gun trigger and attach spray tip. Refer to the spray gun’s
Technical Data Sheet or Owner's Manual for tip installation
and selection of the proper tip size.

8. Test spray pattern. Operate the pump at the lowest hydraulic

pressure which provides good atomization. See the
Troubleshooting section in this manual if you are not getting
the proper pattern.

9. Operating pressure is adjustable from 400 to 3300 psi (228

bar) by turning the pressure control knob clockwise. Do
not turn the knob clockwise more than necessary to
provide satisfactory atomization. Excess pressure wears
out spray tips.

10. When restarting the unit, reduce the pressure at the

pressure control adjustment knob and the pressure bleed
valve.

Color Change/Clean Out/Flushing

Special cleanup instructions for use with flammable
solvents:

• Always flush spray gun at least one hose length from

spray pump.

• If collecting flushed solvents in a one gallon metal

container, place it into an empty five gallon metal
container, then flush solvents.

• Area must be free of flammable vapors.
• Follow all cleanup instructions.

Pressure Relief Procedure

Always reduce pressure when you are cleaning a clogged
tip, changing a tip, servicing any part of the system, or
shutting down. Follow the steps below:

1. Engage the gun trigger lock.
2. Shut off the power source.
3. Close the orange handle shut-off ball valve on the hydraulic

pressure hose.

4. Open the pressure bleed valve by turning it

counterclockwise at least three full turns.

5. Disengage the gun trigger lock and hold trigger open until

flow of material stops.

6. Be certain to hold a metal part of the gun firmly to the side

of a grounded metal container.

Cleaning a Clogged Tip

1. Follow the “Pressure Relief Procedure” above.
2. If tip clogs, rotate tip handle 180° until arrow on handle is

facing the opposite of spray direction and clicks in reverse
position.

3. Trigger gun once so that the pressure can blow the clog

out. NEVER use the tip in the reverse position for more
than ONE trigger pull at a time. This procedure can be
repeated until the tip is free of clogging.

The flow from the spray tip is at very high pressure.
Contact with any body part may be dangerous. Do not
place finger on gun outlet. Do not point the gun at any
person. Never operate the spray gun without the proper tip
guard.

Color Change/Clean Out

Use only compatible solvents when cleaning out oil based
enamels, lacquers, coal tar, and epoxies. Check with the
fluid manufacturer for the recommended solvent.

1. Reduce pressure by turning the pressure control knob and

the pressure bleed valve on the bleed line
counterclockwise. Follow the “Pressure Relief Procedure”
above. The pressure bleed valve should be turned
counterclockwise at least three full turns.

2. Pull siphon tube out of material container.
3. Remove spray tip from gun. Hold gun trigger open until

material flow stops.

4. Put siphon tube into wash solvent or water as applicable,

and operate pump slowly at low pressure until solvent flows
freely from pressure bleed valve line.

5. Close pressure bleed valve and hold gun trigger open until

solvent flows freely from gun. If solvent is not too dirty,
recirculate it by flowing gun stream back into solvent
container. Use additional clean solvent and repeat
procedure if necessary.

6. Check gun strainer screen and pump outlet filter screen

daily. Use 50 mesh screens with spray tip size .015 and
larger. Use 100 mesh screens with spray tip sizes .013 and
smaller.

7. Replace paint filter cap to maximum clockwise rotation.

The filter cover should be hand removable after the first or

second use with new

PTFE

o-ring.

IMPORTANT: O-Ring must have

PTFE

backup washer

to seal properly.

8. If unit has been spraying a water soluble material, flush
