Gun Setup
10. Turn on the air to the gun. Turn ON (I) the ES
On-Off switch (J).
11. Spray a test pattern. Check the atomization.
Note
If the atomization is too fine, or if the
object being sprayed is moving too
much, adjust the atomizing air restrictor
valve (G) counterclockwise slightly to
limit the air flow. To improve atomization,
adjust the atomizing air restrictor valve
(G) clockwise slightly to increase the air
flow or decrease the fluid flow.
12. Adjust the pattern size.
• For the largest spray pattern, fully close the fan
air adjustment valve (F) clockwise.
• For the smallest spray pattern, fully open the
fan air adjustment valve (F) counterclockwise.
13. Spray a test piece. Examine the edges
for coverage. If wrap is poor, see
Troubleshooting, page

Procedure
Procedure Procedure
To extend wear life, perform the following tasks each
day:
• Clean the gun. See Clean the Gun Daily, page
• Inspect the electrode and replace if damaged. See
Electrode Replacement, page
To extend wear life with abrasive, metallic, and
extremely abrasive materials, do the following:
1. To convert a gun for abrasive materials:
• Select a precision high wear
or high wear nozzle. See
Fluid Nozzle Selection Chart, page
Size the nozzle properly to reduce fluid
pressure below 30 psi (0.21 MPA, 2.1 bar),
producing an 8-12 in (200-300 mm) fluid
stream.
• Use 24N632 ES On-Off and Fixed Fluid Valve.
2. Follow steps 1–18 in the
Gun Setup Procedure, page
3. Start the pump. Adjust the fluid regulator until the
stream from the gun travels 8-12 in. (200-300
mm) before falling off. Typically, if fluid pressure
is below 5 psi (.04 MPa, 0.4 bar) or above 30 psi
(0.21 MPa, 2.1 bar), a change of nozzle size is
recommended.
Note
Operate the gun with the fluid adjustment
knob in the full flow position at all times
or install 24N632 ES On-Off and Fixed
Fluid Valve. Always use an external
fluid regulator. Do not use the fluid
adjustment knob to set the fluid pressure.
