How to Operate the Gun
1. Connect an electrically conductive fluid hose (A) to
the gun inlet.
2. With no tip installed, start the pump. Flush the pump
according to the instructions supplied with it. Use
the lowest pressure possible. Prime the system with
the material.
3. Relieve pressure.
4. Install the SwitchTip (8) and tip guard (30). Follow
the instructions in the manual, supplied.
5. Start the pump. Trigger the gun onto test paper.
Adjust the fluid pressure until the spray is com
pletely atomized. Use the lowest pressure neces
sary to get the desired results. Higher pressure may
not improve the spray pattern and will cause prema
ture tip and pump wear.
6. If adjusting the pressure does not give a good spray
pattern, relieve pressure and then try another tip
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.
2. The spray tip orifice and spray angle determines the
coverage and size of pattern. When more coverage
is needed, use a larger spray tip rather than increas
ing fluid pressure.
To reduce the risk of component rupture, and serious
injury, including fluid injection, do not exceed the
gun’s
4000 psi (276 bar, 27.6 MPa) Maximum
Working Pressure
or the maximum working
pressure of lowest rated component in the system.

NOTICE
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.
