Operation Manual

5. Initial Operation
Connect the paint spray gun
to a suitable pressurised air
source by means of a flexible
air hose fitted with a quick
coupler. Set the filter pres-
sure reducer of the pressuri-
sed air source to the required
working pressure (max. 5
bar). Follow the paint manu-
facturer’s instructions for
preparing the spraying
material. Too much working
pressure causes a very fine
spraying material atomisa-
tion with rapid evaporation,
resulting in a rough surface
finish and poor bonding.
If the air pressure is too low,
the spraying material will be
insufficiently atomised,
resulting in rippled surfaces
and drip marks. The paint
spray gun is operated by
pulling the trigger (item 1).
Always hold paint spray gun
at even distance to object,
distance should be approx.
15 cm.
Spray pattern adjuste-
ment:
With the spray pattern
adjusting screw (item 6) the
spray gun can be set to spray
a round or wide pattern. Use
a round spray pattern for
small areas, corners and
edges and the wide
horizontal or vertical pattern
for large areas. The amount
of spraying material is set
with the fluid regulating
screw (item 4).
Open the fluid regulating
screw by approx. 2 to 21/2
turns and make a spray test.
Additional opening of the
fluid regulating screw
increases fluid flow and thus
the spray speed. Closing the
fluid regulating screw
reduces the fluid flow and the
spray speed. Because of the
great variety of spraying
materials fluid flow
adjustment should always be
made when spraying.

6. Care and Maintenance
Thoroughly clean and ser-
vice the paint spray gun after
each use.
Do not use solvents con-
taining halogenated hydro-
carbon (trichlor methyl, ethyl
chloride, etc.), which could
resolve some of the spray
gun’s materials and lead to
dangerous reactions.
A cleaned spray gun will
perform trouble-free when
used the next time.
Periodically all moving parts
should be lightly oiled. If the
nozzle is removed for clea-
ning, its threads and gasket
should be greased before
reassembly.
Do not use lubricants contai-
ning silicone.
Caution: Do not immerse
complete spray gun in sol-
vent!
Nozzle and valve needle are
wearing parts. It is recom-
mended you keep a replace-
ment nozzle kit on hand (see
chapter 9 „Accessories“).
Store your air tools in dry
rooms only.
