Pressure Relief Procedure
1. Turn off gun air supply.
2. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger gun to relieve
pressure.
Adjust Spray Pattern
Do not exceed maximum working air pressure
shown on front cover. Read warnings.
1. Rotate air cap (1) to change spray pattern
direction.
2. For maximum fluid flow and to prevent
premature fluid nozzle wear, turn fluid
adjustment knob (8-2) counterclockwise
until no trigger restriction is felt. Then turn
knob out 1/2 turn more.
3. If further fluid flow restriction is needed,
use different size needle/nozzle/air cap
combination.
If necessary, fluid adjustment knob (8-2)
can be turned clockwise to reduce volume
of fluid output. However, continuously
spraying with fluid adjustment knob closed
causes accelerated abrasive wear on fluid
needle and trigger/air valve shaft interface.
If fluid adjustment knob (8-2) is turned in
all the way, the gun emits only air.
4. Test spray pattern and atomization
while holding gun about 6 to 8 inches
(150 to 200 mm) from test piece.
4
a. If pattern is too wide, turn pattern
adjustment knob (5) clockwise to
narrow pattern.
b. To create a round pattern, turn pattern
adjustment knob (5) fully clockwise.
c. If pattern is too narrow, turn knob (5)
counterclockwise.
d. Check atomization. Increase gun air
supply pressure in 5 psi (34 kPa,
0.3 bar) increments until you have
the desired atomization.
Applying Paint
For the best results:
•
Keep gun perpendicular to surface and
consistent distance of about 6-8 inches
(150-200 mm). Do not angle the gun as you
spray.
•
Use smooth, even strokes, with about 50%
overlap.
•
Mini-HVLP and HVLP Guns: Use a slightly
slower hand movement and make fewer
passes than you would with a conventional
air spray gun. Take care to avoid runs or
sags.
