2.See FIG. 2. Close gun air regulator (E) and pump air regulator (F) by turning knobs counterclockwise reducing pressure to zero. Close bleed-type air valve (D).

3.Connect air line to bleed type air valve.

4.Check that all fittings throughout system are tight- ened securely.

5.Position pail close to pump. Suction hose is 3 ft

(0.9 m) long. Do not stretch hose tight; let it hang to assist fluid flow into pump.

6.Hold metal part of gun firmly to side of grounded metal pail, unlock trigger, and hold trigger open.

7.Open bleed-type air valve. Slowly turn pump air reg- ulator clockwise, increasing pressure until pump starts.

8.Cycle pump slowly until all air is pushed out and pump and hoses are fully primed.

9.Release gun trigger and lock trigger safety. Pump should stall against pressure.

Install the Spray Tip

Follow Pressure Relief Procedure, page 10. Install the spray tip and tip guard as explained in your separate gun manual, supplied.

The fluid output and pattern width depend on the size of the spray tip, the fluid viscosity, and the fluid pressure. Use the Spray Tip Selection Chart in your gun instruc- tion manual as a guide for selecting an appropriate spray tip for your application.

NOTE: The maximum recommended spray tip size is

.019 in. (0.483 mm).

Operation

Adjust the Atomization

NOTE: Use this procedure with airless and air-assisted spray guns.

1.Do not turn on atomizing air supply. Fluid pressure is controlled by the air pressure supplied to the pump (pump air regulator). Set fluid pressure at low starting pressure. For low viscosity fluids (less than 25 sec, #2 Zahn cup) with lower percent solids (typi- cally less than 40%), start at 300 psi (2.1 MPa, 21 bar) at pump outlet. For fluids with higher viscosity or higher solids content, start at 600 psi (4.2 MPa, 42 bar). Refer to the following example.

2.Hold gun perpendicular and approximately 12 inches (304 mm) from surface.

3.Move gun first, then pull gun trigger to spray onto test paper.

4.Increase fluid pressure in 100 psi (0.7 MPa, 7 bar) increments, just to the point where a further increase in fluid pressure does not significantly improve fluid atomization. Refer to the following example.
