3.7 OPERATING THE SPRAY GUN
Fill the cup as necessary (up to the shoulder maximum) with the properly diluted paint or coating. Do not
overfill the cup as this may cause leakage or may block the air pressure holes and prevent pressurization
of the cup.
Spray Pattern Selection
To select the desired spray pattern, rotate the Air Cap at the front of the gun. When Air Cap is in the
diagonal position, the spray pattern will be round; when in the horizontal position, the spray pattern will
be vertical; and when in the vertical position, the spray pattern will be horizontal.
Air Cap Position
Spray Pattern
To adjust the size of the pattern when spraying with a “S” gun (11CS or 11PS: Spring Loaded Air
Cap), turn the Sleeve Nut on the front of the gun, and lock it in place with the Locking Ring once the
proper size has been determined. To adjust the size of the pattern when spraying with a Fixed Air Cap
Gun (10C, 11C, or 11P), use the Material Flow Adjustment Screw as a means of adjusting the pattern
size. If this is not adequate, upgrade to a “S” gun for finer control.
CAUTION: When adjusting the size of the spray pattern with a “S” gun, moving the Air Cap too close
to the Fluid Tip may cause an undesirable figure-8 pattern; moving the Air Cap too far from the Fluid Tip
will eventually prevent spraying altogether.
To Begin Spraying
Switch the turbine power switch to the ON position.
To control the thickness of the coat being applied, slowly turn the Material Flow Adjustment Screw (at
rear of gun) counter-clockwise while squeezing the trigger of the gun. Continue turning the screw until
the appropriate material flow has been achieved to provide the desired coating thickness and finish. For
best results, select the Needle, Fluid Tip and Air Cap combination that allows you to have the trigger fully
engaged.
Maintain a consistent distance of 6-8 inches from the surface and spray in a smooth continuous motion.
