SIPHON FEED CUP HOOKUP
Air pressure for atomization is regulated at
extractor. Amount of fluid is adjusted by fluid
control screw on gun, paint viscosity and
air pressure.
PRESSURE FEED CUP HOOKUP
Air pressure for atomization is regulated at
extractor. Fluid pressure is regulated at cup
regulator. For heavy fluids and internal mix
nozzle spraying, fluid adjusted control screw on
gun, pressure cup also available less regulator.
PRESSURE FEED TANK HOOKUP
For portable painting operations
(Double regulator) Air pressure for atomization
and fluid supply is regulated by two individual
air regulators on tank.
PRESSURE FEED TANK HOOKUP
For medium production spraying
(Single regulator) Air pressure for atomization is
regulated at extractor. Fluid pressure is regulated
at tank regulator.
PRESSURE FEED CIRCULATING HOOKUP
For heavy production spraying.
Air pressure atomization regulated at extractor.
Fluid pressure is regulated at fluid regulator.

PRESSURE SPRAYING
After selecting correct size fluid, set fluid pressure for the desired flow. Open atomization air and test
spray. If spray is too fine, then reduce air pressure. If spray is too coarse, then raise air pressure. Adjust
pattern width and repeat adjustment of spray.
Keeping fluid control screw in open position will reduce fluid needle wear.
NOTE: To reduce overspray and obtain maximum efficiency, always spray with the lowest possible
atomization air pressure.
OPERATION
Proper handling of the gun is essential for obtaining a good finish. The gun should be held at right
angle to the surface being covered, moving parallel with the surface. For precise control of the gun
and material, the trigger should be released before the end of the stroke.
Hold the gun from 6 to 12 inches (15,24cm to 30,48cm) away from the surface depending on material
and atomizing pressure. For a uniform finish, lap each stroke over the preceding stroke, making sure
the spray is smooth and wet.
Using the lowest possible atomizing air pressure will reduce over-spray and provide maximum efficiency.
