Problem
Gun spitting.
Will not spray.
Excessive air blowing back.
Gun fluid pressure is too high
with gun triggered (cannot
achieve desired flow rate).
Using a low fluid pressure set-
ting, 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)].
Fluid flow is fluttering while
spraying.

Cause
Air getting into paint stream.
Fluid control valve (11) turned
too far clockwise.
Fluid source empty.
Loose fluid nozzle (4).
Damaged fluid nozzle seal (3). Replace seal (3).
Using needle/nozzle kit with
too small orifice.
Using needle/nozzle kit with
too large orifice.
There is no fluid regulator, or
air regulator is not sensitive
enough at low pressure.
Fluid source empty.
Troubleshooting
Solution
Check if fluid source is empty
and fill.
Tighten fluid nozzle (4).
Check fluid nozzle o-ring (3) for
damage.
Check fluid nozzle (4) for dam-
age.
Adjust fluid control valve (11)
counterclockwise.
Refill.
Tighten fluid nozzle (4).
Use needle/nozzle kit with
larger orifice.
Use needle/nozzle kit with
smaller orifice.
Add low pressure fluid regula-
tor, or add more sensitive low
pressure air regulator.
Refill.
