18. Shut off the air to the gun. Turn OFF (O) the ES
On-Off switch (J).
19. 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.
20. Turn on the air to the gun. Turn ON (I) the ES
On-Off switch (J).

21. Spray a test pattern. Check the atomization.
• If over-atomization occurs at minimum
pressure, adjust the atomizing air restrictor
valve.
• If atomization is inadequate, increase air
pressure or decrease fluid flow.
22. Adjust the fan air adjustment valve.
• Fully open the fan air adjustment valve,
counterclockwise, for the longest pattern.
• Turn the valve clockwise to restrict the fan air
and create a shorter pattern.
When the ES On-Off switch is turned ON (I),
the fluid supply is charged with high voltage
until the voltage is discharged. Contact with
the charged components of the spray gun will
cause an electric shock. Do not touch the gun
nozzle or electrode or come within 4 in. (102
mm) of the front of the gun during operation.
23. Spray a test piece. Examine the edges
for coverage. If wrap is poor, see
