Problem
Using a low fluid pressure
setting, the fluid flow is
too high, making it
necessary to restrict
needle travel to reduce
fluid flow.
Fluid system will not
operate at low enough
pressure [below 10 psi
(70 kPa, 0.7 bar)].

Cause
Using needle/nozzle kit
with too large orifice.
There is no fluid
regulator, or air regulator
is not sensitive enough
at low pressure.
Solution
Use needle/nozzle kit with smaller orifice.
Add low pressure fluid regulator, or add more
sensitive low pressure air regulator.
