The spray pattern can be adjusted by changing:
• Tip (CG) size
• Air flow, use air ball valve (CB)
• Air Needle (CD) position

Air Flow:
Flow:
Flow: Adjust the air assist shutoff ball valve
(CB) for the minimum air flow necessary for a good
pattern. Air bleeds from the applicator nozzle (CG)
whenever the applicator air assist shutoff ball valve
(CB) is open. Close the valve to stop the air flow,
if desired. Otherwise, the air valve can stay open
during priming. Air must be on prior to fluid flow.
Adjust Adjust Adjust Air Air Air Needle Needle Needle (CD) (CD) (CD) position: position: position: Make sure the
air needle (CD) is slightly behind the tip (CG). The
general rule for setting the air needle position is that
the air needle should be the same distance back
from the tip as the size of the orifice. For example, if
you have a 1/2 in. tip installed, the air needle should
be approximately 1/2 in. behind the tip.
NOTE: NOTE:
NOTE: Installing the needle too far forward can
restrict or completely block material flow. This can
result in the retainer (CC) blowing off. Installing the
needle too far back can raise the pressure behind the
fluid enough to blow the retainer (CC) off and can
cause dripping.

To decrease air flow, turn valve knob clockwise.
To increase air flow, turn valve knob
counterclockwise.
Check material and thin as needed to maintain the
proper consistency. The material may thicken as it
sits and could slow down application or affect the
spray pattern.
Flush and dry applicator thoroughly at the end of each
use. Tips and retainers must be cleaned by hand.

Adjustments
For a lighter spray pattern, adjust the air needle
closer to the fluid nozzle and/or reduce the fluid flow.
For a heavier spray pattern, adjust the air needle
farther back from the fluid tip and/or increase the
fluid flow.
NOTE: NOTE: NOTE: Withdrawing the needle too far can force air
pressure back into the fluid hose, which can slow
material flow.
