Adjusting the Fluid Flow
The fl uid fl ow can be adjusted by using
the needle adjustment screw as noted
in Fig. 1. As a starting point, gently turn
the knob clockwise until you have very
little needle travel (pull trigger to verify).
Do not over-tighten. After the needle
travel has stopped, further tightening will
only serve to compress the spring and
will not aid in adjustment. Next turn the
knob counterclockwise two full turns.
These adjustment procedures will serve
only as a starting point. Fine tuning of
these adjustments will be based on your
material and technique.
