When adjusting flow adjustment
nut (B), release trigger (C), then
adjust.
If adjusting while triggered,
needle will turn but provide no
adjustment.
If flow adjustment nut will not
turn, check to see if it is:

• if there is material on threads.
Clean threads as needed

Check material consistency
often. Material may thicken as it
sits and slow down production or
affect spray pattern. Thin with
water as needed to maintain
proper consistency.
