How to use the AirPro gun

See F . 2
IG
1. Make all fluid and air adjustments at the pressure
pot for maximum efficiency. See How to adjust the
air regulators, page 9.
NOTE: Monitor the adjustments made to the gun so if
the results are not satisfactory it can easily be returned
to its previous adjustment. Refer to your gun manual for
more information.
2. Adjusting Air Spray Gun: Use the fan pattern
adjusting valve (E). Normal adjustment is with the
valve turned out fully clockwise and then turned in
two full turns.
• Turn counterclockwise to widen spray pattern.
• Turn clockwise to narrow spray pattern.
Adjusting HVLP Spray Gun: Use the fan pattern
adjusting valve (E).
• For a round spray pattern, turn the pattern
adjusting valve fully in (clockwise).
• For an oval (flat) spray pattern, turn the pattern
adjusting valve fully out (counterclockwise).
3. The fluid adjusting valve (F) is used in systems that
do not have a fluid regulator. As this package
includes a pressure pot regulator (33), use it to
adjust fluid flow. Turn the valve (F) out until full trig-
ger travel is obtained.
4. The gun has a built-in lead and lag operation. When
triggered, the gun emits air before the fluid is dis-
charged. When the trigger is released, the fluid
stops before the air flow stops. This helps assure
the spray is atomized and prevents fluid buildup on
the air cap.
5. Loosen the air cap retaining ring (G) and rotate the
horns (H) of the air cap to obtain the desired spray
position. Tighten the retaining ring snugly, but do
not over tighten it. See F
