NOTICE!
Material damage due to improper
replacement of needle and seal retainer
screw.
Replacing only the needle or only the seal
retainer screw could damage spray gun
components. This can compromise the
tightness of the spray gun. The spray pat-
tern deteriorates.
– Observe order of disassembly steps
(needle – seal retainer screw).
– Observe order of assembly steps (Seal
retainer screw – needle).
– Always replace seal retainer screw and
needle at the same time.
NOTICE!
Property damage due to improper han-
dling
Mechanical load can damage needle and
nozzle.
– Handle with care during installation
and dismantling.
– Do not subject the needle to any
mechanical pressure.
– Avoid collisions of components to be
assembled and disassembled with the
needle.
– Do not excessively tighten compo-
nents.
NOTICE!
Improper setting causes damage
The delay time is factory-set. Setting a
wrong delay time can damage the nozzle
and the needle.
– You should only change the delay time
upon inserting a new needle or in case
there are problems with the spray pat-
tern.
– If in doubt, contact Dürr Systems
