Turning the ring clockwise will make the pattern bigger. Turning the
ring counterclockwise will make the pattern smaller. As you reduce
the spray pattern size, you will need to move closer to the surface.
adjusting the Material Flow
Each individual job and material may require slight adjustments in
the material flow.
Turn the material flow adjustment knob clockwise for less fluid and
counterclockwise for more fluid.

Spraying
Hold the spray gun between 1 and 8 inches from the spraying surface,
depending on the size of the spray pattern that you need. The closer
to the surface you hold the gun, the smaller the spray pattern.
Keep the gun at right angles to the spraying surface in order to apply
an even coat of material. If you keep the spray gun moving at a
smooth and constant speed, the spray material is less likely to run or
sag.

Always squeeze the trigger of the spray gun after you begin your
spray pass and release it before the pass is done. For best results,
make the spray passes about 20 inches long and overlap each pass
by 4 or 5 inches. Remember to keep the gun at right angles to the
spraying surface.

adjusting the Suction Tube
The suction tube on your spray gun lets you get the most out of the
material in your cup no matter at what angle you need to spray.
NOTE: Before adding material to the cup, rotate the suction
tube by hand to the desired direction.
a. If you are going to be spraying in a downward direction, the
angled end of the suction tube should be pointing toward the
front of the gun.
b. If you are going to be spraying in an upward direction, the
angled end of the suction tube should be pointing toward the
rear of the gun.
