Procedure
To convert a gun to achieve a soft spray pattern for
small or lightweight parts, do the following:
1.
Install a soft spray air cap. See
Air Cap Selection Guide, page 96
2.
For best results, install a 1.0 mm
or 1.2 mm fluid nozzle.
See
Fluid Nozzle Selection Chart, page 93
.
3.
Follow steps 1–13 in the
4.
Adjust the atomizing air. Fully close the atomizing
air restrictor valve (G) counterclockwise. Then,
open the atomizing air restrictor valve (G) one
half turn to one turn.
5.
Turn ON (I) the ES On-Off switch (J).
6.
Set the gun air regulator to deliver a minimum
45 psi (0.32 MPa, 3.2 bar) at the gun when
triggered, to ensure full spraying voltage.

Description
Green
When spraying, the indicator
should remain green, indicating
sufficient air pressure to the
alternator turbine.
Amber
If the indicator changes to amber
after one second, the air pressure
is too low. Increase air pressure
until the indicator is green.
Red
If the indicator changes to red
after one second, the air pressure
is too high. Decrease air pressure
until the indicator is green. To
maintain a higher application air
pressure, install ES On/Off Valve
Restrictor Kit 26A160. Adjust the
pressure as needed to ensure the
indicator remains green.

NOTE:
NOTE:
NOTE: The soft spray air cap is optimized for a
production rate of 3.5 oz/min (100 cc/min). For
best soft spray results, limit the production rate
to 7 oz/min (200 cc/min) or less.
NOTE:
NOTE:
NOTE: 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.
