Assembly
 Before any work on the machine itself, pull the mains
plug.
 Ensure that the spray gun and base unit are assembled
completely and with all seals. Only this will ensure the
function and safety of the fine-spray system.
Connecting the Air Hose (see figures A1 – A3)
–Open the holding clamp 24 and unwind the air hose 20
completely from the base unit 22.
Connecting the base unit:
– Insert a bayonet lock 21 of the air hose securely into the
slots in the base unit port 26 according to the arrow marks.
– Turn the bayonet lock a quarter turn clockwise.
Connecting to the spray gun:
– Insert the second bayonet lock 21 of the air hose securely
into the slots in the spray gun port 9 according to the arrow
marks.
– Turn the bayonet lock a quarter turn clockwise.
Note: Remove the air hose 20 before pouring in spray materi-
al (quarter turn of the bayonet lock 21 counterclockwise; pull
the bayonet lock 21 out of the port 9).
Changing the Nozzle Cap (see figures B1–B2)
The fine-spray system is supplied with three nozzle caps:
Note: Check the spray material by stirring it before selecting
the nozzle cap. Thinner-viscosity material (e.g. wood paint)
can be sprayed better with the grey nozzle cap 11 or the black
nozzle cap 12, whereas thicker-viscosity material (e.g. wall
paint) can be sprayed better with the white nozzle cap 10.
– To change the nozzle cap, unscrew the union nut 3.
– Pull off the air cap 2.
– Unscrew the mounted nozzle cap.
–Open the holding clamp 24 and take the required nozzle
cap out of the accessory compartment 27.
– Screw the required nozzle cap onto the thread in the spray
gun.
–Put the air cap 2 on the nozzle cap and tighten it with the
union nut 3.
Operation
 Before any work on the machine itself, pull the mains
plug.
Preparing for Operation
 Spraying on the sides of water bodies (lakes, rivers,
etc.) or neighbouring surfaces in the direct catchment
area is not permitted.
When purchasing paint, varnish and spray material, pay at-
tention to their environmental compatibility.
Preparing the Spray Surface
The spray surface must be clean, dry and grease-free.
– Roughen smooth surfaces and then remove the sanding
dust.
When spraying, all non-covered surfaces can be soiled by the
spray mist. Therefore, thoroughly prepare the area around
the surface to be sprayed:
– Cover or mask off floors, furnishings, doors, windows as
well as door and window frames, etc.
Preparing the Spray Material
– Stir the spray material thoroughly.
– Dilute the spray material if necessary.
 When diluting, pay attention that the spray material
and the diluting agent correspond. When using a faulty
diluting agent, lumps can develop that can lead to clogging
of the spray gun.
 When diluting the spray material, make sure that the
flash point of the mixture is above 55 °C again after di-
luting. Diluting e.g. solvent-based lacquers lowers the
flash point.
Filling in Spray Material (see figures C1 –C2)
Note: Remove the air hose 20 before pouring in spray materi-
al (quarter turn of the bayonet lock 21 counterclockwise; pull
the bayonet lock 21 out of the port 9).
– When using large buckets, pour the spray material into a
smaller transfer bucket 14 if necessary (e.g. 10-l wall paint
into an empty 2.5 or 5.0-l bucket).
– Pull the spray gun off the container 7.
– If you are using already opened spray material, place the
thoroughly cleaned filling sieve 13 on the container 7 to
hold back any lumps of paint when pouring in.
