Spraying
The AirCoat spray system has two different painting modes. The
AirCoat mode is used for fine finish work with low to medium
viscosity materials (oil, stains, lacquers, etc...). The airless mode is
used for general painting with high viscosity materials (latex).
5.1
Spraying in AirCoat mode
Use the AirCoat mode for low-pressure fine finish work
(recommended pump pressure up to 69 bar (6.9 MPa, 1000 PSI).
1. Make sure that the airless spray hose is free of kinks and clear
of objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its lowest
setting.
3. Turn the compressor air pressure regulator (b)
counterclockwise to its lowest setting.
4. Move the compressor ON/OFF switch to the ON position.
5. Move the pump ON/OFF switch to the ON position.
6. Turn the PRIME/SPRAY valve to SPRAY.
7. Turn the pressure control knob clockwise until the material
pressure gauge (a) reads 27.5 bar (2.7 MPa, 400 PSI). The paint
hose should stiffen as paint begins to flow through it.
8. Turn the air pressure regulator (b) clockwise until the air
pressure gauge (c) reads 1.3 bar (0.13 MPa, 20 PSI).

9. Unlock the spray gun gun.
10. Trigger the spray gun to bleed air out of the material hose.
11. When material reaches the spray tip, spray a test area to check
the spray pattern.
12. Adjust the spray pattern to the desired size and atomization.
• Use the pressure control knob to control the flow of paint to
the gun.
• Use the air pressure regulator to control the amount of
atomization air available to the gun.
• Use the pattern adjustment knob on the gun to fine tune
the spray pattern.

Refer to the spray gun Owner’s Manual for
information on the operation of the gun.
5.2
Spraying in Airless Mode
Use the airless mode for general high-pressure spraying (pump
pressure from 34.4 bar (3.4 MPa, 500 psi) to 193 bar (19.3 MPa, 2800
PSI).
1. Make sure that the airless spray hose is free of kinks and clear
of objects with sharp cutting edges.
2. Turn the pressure control knob (d) counterclockwise to its
lowest setting.
3. Turn the PRIME/SPRAY valve (e) to SPRAY.

4. Move the pump ON/OFF switch to the ON position.
5. Make sure the compressor ON/OFF switch is in the OFF
position.
6. Turn the pressure control knob clockwise to its highest
setting. The paint hose should stiffen as paint begins to flow
through it.
7. Unlock the gun by turning the gun lock nut counter-clockwise
(when looking from the back of the gun) three full turns. This
opens the material valve in the gun.
8. Trigger the spray gun to bleed air out of the material hose.
9. When material reaches the spray tip, spray a test area to check
the spray pattern.
10. Use the lowest pressure setting necessary to get a good spray
pattern.
a. If the pressure is set too high, the spray pattern will be too
light.
b. If the pressure is set too low, tailing will appear or the paint
will spatter out in “gobs” rather than in a fine spray.
