General Adjustments
The spray pattern can be adjusted by changing:
•
Tip (E) size
•
Fluid flow
•
Air flow, use needle valve (G)
•
Air needle (B) position
Adjust Air Flow: Fully open the air assist valve (H),
while adjusting the needle valve (G) for the minimum air
flow necessary for a good pattern. Air bleeds from the
applicator nozzle whenever the applicator air valve (H)
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 Air Needle (B) position: Ensure the air needle
(B) slightly behind the tip (E).
NOTE: Installing needle (B) too far forward can restrict
or completely block material flow. This can result in the
retainer (F) blowing off. Installing the needle too far back
can raise the pressure behind the fluid enough to blow
the retainer (B) off and can cause dripping.
Air Flow Valve Adjustment
To decrease air flow, turn valve knob (G) clockwise.
To increase air flow, turn valve knob (G) counterclock-
wise.
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 pat-
tern.
Flush and dry applicator thoroughly at the end of each
use. Tips and retainers must be cleaned by hand.
