SS-1150
AIR SPRAY GUN
Your new spray gun is exceptionally rugged in construction. And is built to stand up under hard. Continuous
use. However, like any other fine precision instrument. Its most efficient operation depends on a knowledge
of its construction. Operation and maintenance. Properly handled and cared for it will produce beautiful.
Uniform finishing results long after other spray guns have worn out.

Siphon Feed Cup Hookup

Air pressure for atomization is regulated at extractor.
Amount of fluid is adjusted by fluid control screw on Gun.
Viscosity of paint. And air pressure

Pressure Feed Cup Hookup

For fine finishing with limited spraying.
Air pressure for atomization is regulated at extractor,
Fluid pressure at cup regulator. For heavy fluids and
Internal mix nozzle spraying. Fluid adjusted by control
screw on gun
Pressure cup also available less regulator.

Pressure Feed Tank Hookup

For medium production spraying (single regulator)
Air pressure for atomization in regulated at extractor.
Fluid pressure at tank 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 circulating hookup

For heavy production spraying.
Air pressure atomization regulated at extractor.
Fluid pressure regulated at fluid regulator.

Gun Handing

The first requirement for a geed resultant finish is the proper handing of the gun. The gun should be held
perpendicular to the surface being covered, and moved parallel with it. The strike should be started before
the trigger is pulled and the trigger should be released before the strike is ended. This gives accurate control
of the gun and material.
The distance between gun and surface should be 6 to 12 inches depending on material and atomizing
pressure. The material deposited should always be even and wet. Lap each stroke over the preceding stork
to obtain a uniform finish.
Note: to reduce overspray and obtain maximum efficiency. Always spray with the lowest possible atomizing
air pressure
Spray width adjustment, turn right for round, left for fan
Fluid control screw, turn to right to decrease flow, left to increase.
As width of spray is increased, more material must be allowed to pass through
the gun to obtain the same material must be allowed to pass through to gun to
obtain the same coverage on the increased area.

Siphon spraying

Set atomization pressure at approximately 50psi for lacquer and
60 psi for enamel. Test spray. If the spray is too fine. Reduce
the air pressure or open fluid control screw. If the spray is too
coarse, close the fluid control screw. Adjust the pattern width
and repeat adjustment of spray necessary.
