Gun Setup
13. Setting the Atomization Fluid Pressure
Atomization fluid pressure will vary based on the type
of fluid used, the flow rate desired, the fluid tempera-
ture, and the percentage of CO
2 used. Follow the
recommendations of your material and equipment
supplier.
14. Using the Electrostatics
Turn the ES ON-OFF lever (26) to ON. This will acti-
vate the electrostatics.
Some objects with deep crevices or internal features
may be painted more efficiently with the electrostatics
turned off or in the LO setting (see 15 below). Be sure
to turn off the electrostatics any time you are flushing
the gun (see page 18).
NOTE: When spraying, the ES indicator light (K) will
glow, indicating the electrostatic charge.
15. Use the ES HI-LO lever (43g) to change
to either full voltage (HI) or a lower volt-
age level (LO).
