To reduce the risk of a skin in- jection injury, always follow the Pressure Relief Procedure, page 27, before removing or installing the spray tip, air cap, or tip guard.

11.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, page 62, as a guide for selecting the appropriate spray tip for your application.

12.Align the spray tip tab with the groove in the air cap. Install the tip.

13.Install the air cap and retaining ring. Orientate the air cap and tighten the retaining ring securely.

14.Close the atomizing air adjustment valve (G) and the fan air adjustment valve (F).

15.Check that the ES On-Off switch is OFF (O).

16.Start the pump. Set the fluid regulator to 400 psi (2.8 MPa, 28 bar).

17.Spray a test pattern. Examine the particle size in the center of the pattern (tails will be removed in step 21). Increase the pressure in small increments. Spray another pattern. Compare particle size. Continue increasing pressure until the particle size remains constant. Do not exceed 3000 psi (21 MPa, 210 bar).

18. Turn ON (I) the ES On-Off switch.
