10. Unlock the gun by turning the gun trigger lock to the

unlocked position.

Ground the gun by holding it against the
edge of the metal container while flushing.
Failure to do so may lead to a static electric
discharge, which may cause a fire.

11. Trigger the gun into the metal waste

container until the old solvent is gone and fresh solvent is
coming out of the gun.

12. Lock the gun by turning the gun trigger

lock to the locked position.

13. Set down the gun and increase the

pressure by turning the pressure
control knob slowly clockwise into the
green zone.

14. Check the entire system for leaks. If

leaks occur, follow the “Pressure Relief
Procedure” in this manual before tightening any fittings or
hoses.

15. Follow the “Pressure Relief Procedure” in this manual

before changing from solvent to paint.

Be sure to follow the pressure relief procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray tips, or preparing for cleanup.

Painting

1. Place the suction tube into a container of paint.
2. Place the return hose into a metal waste container.
3. Set the pressure to minimum by turning

the pressure control knob to the “Min”
setting in the yellow zone.

4. Move the PRIME/SPRAY valve down to

the PRIME position.

5. Turn the unit on by moving the ON/OFF

switch to the ON position.

6. Allow the sprayer to run until paint is coming through the

return hose into the metal waste container.

7. Turn the unit off by moving the ON/OFF switch to the OFF

position.

8. Remove the return hose from the waste container and

place it in its operating position above the container of
paint.

9. Move the PRIME/SPRAY valve up to the SPRAY position.

10. Turn the unit on.

11. Unlock the gun by turning the gun trigger lock to the

unlocked position.

Ground the gun by holding it against the
edge of the metal container while flushing.
Failure to do so may lead to a static electric
discharge, which may cause a fire.

12. Trigger the gun into the metal waste

container until all air and solvent is flushed from the spray
hose and paint is flowing freely. from the gun.

13. Lock the gun by turning the gun trigger

lock to the locked position.

14. Turn the unit off.
15. Attach tip guard and tip to the gun as

instructed by the tip guard or tip
manuals.

WARNING

POSSIBLE INJECTION HAZARD. Do not spray without the
tip guard in place. Never trigger the gun unless the tip is in
either the spray or the unclog position. Always engage the
gun trigger lock before removing, replacing or cleaning tip.

16. Turn the unit on.
17. Increase the pressure by turning the pressure control knob

slowly clockwise toward the green zone and test the spray
pattern on a piece of cardboard. Adjust the pressure
control knob until the spray from the gun is completely
atomized. Try to keep the pressure control knob at the
lowest setting that maintains good atomization.

Electronic Pressure Control Indicators

The following is a description of the indicators on the electronic
pressure control.

Pressure Indicator

The pressure indicator shows the current operating pressure of
the sprayer. It has three different indications: blinking yellow,
solid yellow, and solid green.

Blinking Yellow

When the pressure indicator is blinking yellow, the sprayer is
operating between 0 and 200 PSI. A blinking yellow pressure
indicator means:

• The sprayer is plugged in and turned “ON”
• The sprayer is at priming pressure (little or no pressure)
• It is safe to move the PRIME/SPRAY valve between

positions

• It is safe to change or replace the spray tip (refer to gun

manual for tip replacement instructions).

Solid Yellow

When the pressure indicator is solid yellow, the sprayer is
operating between 200 and 1800 PSI. A solid yellow pressure
indicator means:

• The sprayer is at the proper pressure setting for spraying

stain, lacquer, varnish, and multi-colors

• If the pressure indicator goes to solid yellow when the

pressure is set so that it starts at solid green, it indicates
one of the following:

a. Tip Wear Indicator — when spraying with latex or at

high pressure the solid yellow appears. This means
the tip is worn and needs to be replaced.

b. Tip Too Large — when a tip that is too large for the

sprayer is put in the gun, the pressure indicator will turn
from solid green to solid yellow.

c. Fluid Section Wear — if a solid yellow pressure

indicator appears when using a new tip and the
pressure is set at maximum, service may be required
(worn packings, worn piston, stuck valve, etc...).

NOTE: If the pressure indicator begins blinking yellow

when the pressure control knob is set at a
higher pressure and the PRIME/SPRAY valve is
in the SPRAY position, either the spray tip is
worn, there is a leak, or the sprayer is in need
of service/repair.
