GRAVITY 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.

This spray gun is rugged in construction, and is built to yield exceptional value. The life of this product and the efficiency
of its operation depend upon a knowledge of its construction, use and maintenance.
INSTALLATION
Never mount oil and water extractor on or near the air compressor.
During compression, air temperature is greatly increased. As the air cools down to room temperature, moisture
condenses in the air line, on its way to the spray gun. Therefore, always mount the oil and water extractor at a point in
the air supply system where the compressed air temperature is lowest.
Drain air lines properly.
Pitch all air lines back towards the compressor so that condensed moisture will flow back into the air receiver where
it can be drained off. Each low point in an air line acts as a water trap. Such points should be fitted with an easily
accessible drain. See diagram above.
