INSTALLATION
Connect the Air Lines
1.
Install an air filter to provide a clean, dry air supply to
the gun. Dirt and moisture in the air line can affect the
appearance of your finished workpiece.
2.
Install a normally closed, 3-way air solenoid valve in
the cylinder air supply line. Connect an air hose from
the solenoid valve to the 1/4–18 npsm (R 1/4–19)
gun air inlet marked CYL.
3.
Connect an atomizing air supply line to the 3/4–11.5
NH (standard garden hose fitting) gun air inlet
marked ATOM.
4.
Install separate air regulators to control atomizing air
and cylinder air.

OPERATION
WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin or injury from
moving parts, always follow this procedure when
shutting off the system, when checking or servicing
any part of the spray system, when installing,
cleaning or changing fluid nozzles, and whenever
you stop spraying.
1.
Turn off the air and fluid supply to the gun.
2.
Trigger the gun into a grounded metal waste
container to relieve fluid pressure.
Filter the Fluid and Check Viscosity
Filter the fluid to remove coarse particles and sediment
which could clog the spray nozzle, then check the viscos-
ity of your fluid. This gun is best suited for light to medium
fluids.
Light Fluid: 19 to 24 seconds (No. 2 Zahn cup). Auto,
Furniture, Appliances, Fine Finish Metallics, Top Coats,
Lacquer, Enamel Primer.
Medium Fluid: 22 to 41 seconds (No. 2 Zahn cup). Con-
tact Adhesive, Latex, Maintenance Paints, Textures,
Primers, Epoxies, Vinyls, High Flow High Viscosity.
Heavy Fluid: 2.8 Volatile Organic Compounds, High-
solid Polyurethanes, Heavy Waterborne Enamels
Position the Air Cap
The direction of the spray pattern is controlled by the
position of the air cap. See Fig 1. Loosen and turn the air
cap to the desired position, then hand tighten the air cap
securely.
Adjust the Spray Pattern
Follow these steps to establish the correct fluid flow and
air flow:
Vertical Pattern
Horizontal Pattern
Fig 1
0897
1.
Adjust the pattern size by turning the pattern adjust-
ing valve
OUT (counterclockwise) for a wider pattern
or
IN (clockwise) for a narrower pattern
.
Refer to Fig
2.
NOTE: The pattern width at the widest adjustment is 10
to 11 in. (254 to 279 mm) at 350 grams/min. fluid
flow and 10 in. (254 mm) target distance with 15
psi (1.05 bar) inlet air pressure. (Measurements
taken using a 23 sec. Zahn #2 viscosity fluid.)
The pattern length will vary with the fluid flow, air
pressure, fluid viscosity, and other factors.
2.
To adjust the volume of fluid output:
a.
Turn the fluid adjusting valve
all the way out
(counterclockwise). Refer to Fig 2.
b.
Adjust the fluid regulator for the desired pres-
sure.
c.
For final adjustment, turn the fluid adjusting
valve in
(clockwise) to reduce the volume of fluid
output and obtain the desired results.
NOTE: If the fluid adjusting valve is turned in all the way
the gun will only emit air.
