System Component Information

I.How to use the AirPro gun

See Fig. 2.

1.Make all fluid and air adjustments at the pressure pot for maximum efficiency. Refer to page 8.

2.If you make adjustments at the gun, take note of what you do. Then, if the results are not satisfac- tory, you can easily return the gun to its previous adjustment. Steps 3 and 4 explain the gun adjust- ments. Refer to your gun manual for more informa- tion.

3.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.

a.Turn counterclockwise to widen spray pattern.

b.Turn clockwise to narrow spray pattern.

Adjusting HVLP Spray Gun: Use the fan pattern adjusting valve (E).

a. For a round spray pattern, turn the pattern

adjusting valve fully in (clockwise).

b. For an oval (flat) spray pattern, turn the

pattern adjusting valve fully out (counterclock-

wise).

4. 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

5.The gun has a built-in lead and lag operation. When triggered, the gun emits air before the fluid is discharged. 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.

6.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 Fig. 2 and 3.

7.Clean and lubricate the gun as instructed in your separate gun manual.
