Gun Setup
Soft Spray Spray Gun Gun Setup Setup Procedure
Soft Soft Spray Gun Setup
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
2. For best results, install a 1.0 mm
or 1.2 mm fluid nozzle. See
Fluid Nozzle Selection Chart, page
3. Follow steps 1–13 in the
Gun Setup Procedure, page
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.

When spraying, the indicator
Green
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.
8. Continue with steps 18–23 in the
Gun Setup Procedure, page
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
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.
