Gun Setup
19. Shut off the air to the gun. Turn OFF (O) the ES
On-Off switch (J).
20. Start the pu
mp. Adjust the fluid regulator until the
stream from
the gun travels 8-12 in. (200-300
mm) before f
alling off. Typically, if fluid pressure
is below 5 ps
i (.04 MPa, 0.4 bar) or above 30 psi
(0.21 MPa,
2.1 bar), a change of nozzle size is
recommend
ed.
21. Turn on the air to the gun. Turn ON (I) the ES
On-Off switch (J).
22. Spray a test pattern. Check the atomization. If
over-atomization occurs at minimum pressure,
adjust the restrictor valve. If atomization is
inadequate, increase air pressure or decrease
fluid flow.
23. Adjust the fan air adjustment valve: clockwise for
a narrower pattern, counterclockwise for a wider
pattern.
24. Spray a test piece. Examine the edges
for coverage. If wrap is poor, see
Troubleshooting, page 33.
