Installation/Operation
How to Operate the Gun
WARNING
To reduce the risk of component rupture, and seri-
ous injury, including fluid injection, do not exceed
the gun’s 4000 psi (276 bar, 27.6 MPa ) Maximum
Working Pressure or the maximum working pres-
sure of lowest rated component in the system.

1. Connect an electrically conductive fluid hose (A) to
the gun inlet. See Fig. 2.
2. With no tip insta lled, start the pump. Flush the
pump according to the instructions supplied with it.
Use the lowest pressu re possible. Prime the
system with the material.
3. Relieve pressure.
4. Install the SwitchT ip (8) and tip guard (30). Follow
the i nstructions in the manual, supplied.
See Fig. 2.
5. Start the pump. Trigger the gun onto test paper.
Adjust the fluid pressure until the spray is
completely atomized. Use the lowest pressure
necessa ry to get the desired results. Higher pres-
sure may not improve the spra y pattern and will
cause premature tip and pump wear.
6. If adjusting the pressure does not give a good
spray pattern, relieve pressure and then try
another ti p size.
7. Use a full-open, full-close trigger action. Hold the
gun about 14 in. (350 mm) from and at right angles
to the work surface. Don’t swing the gun in an arc.
Practice to find the best length and speed of
stroke.
How to Adjust the Spray Pattern
1. To adjust the spray pattern direction, relieve pres-
sure. Loosen the tip guard retaining nut (B). Turn
the tip guard/tip groove horizontally (C) for a hori-
zontal pattern and vertically (A) for a vertical
pattern. Tighten the nut. See Fig. 3.
2. The spray ti p ori fice and spray angle determines
the coverage and size of patte rn. When more
coverage is needed, use a larger spray tip rather
than increasing fluid pressure.
CAUTION
Openings in the tip guard reduce paint buildup on
the guard while spraying. Damage to the sharp
edges of the openings causes paint to collect at
that area. Never hang the gun by the tip guard.
