Troubleshooting
8.2.1 Replace needle and nozzle.
NOTICE!
Property damage due to improper
replacement of needle and nozzle
Replacing only the needle or only the
nozzle could damage spray gun compo-
nents. This can compromise the tightness
of the spray gun. The spray pattern deteri-
orates.
– Observe order of replacement steps
(needle – nozzle).
– Observe order of assembly steps
(nozzle – needle).
– Always replace nozzle and needle at
the same time.
The integrated Quick Clip technology allows
for removal and installation of the needle
without changing the preset needle stop.
