The spray surface must be clean, dry and grease-free.
– Roughen smooth surfaces and then remove the sanding dust.
Suitable spray materials and recommended diluting
agents
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.
Spray material
Wood stains, oils, glazes, impregna-
tions, anti-rust primers
Water, wallpaper remover
Solvent or water-dilutable paints, prim-
ers, radiator paint, automotive top
coats, thick-coat finishes
The tool is not suitable for processing dispersion paint (wall
paint/latex).
Please also observe the practical advice/tips of the spray ma-
terial manufacturers.
Diluting Spray Material
For spray material that needs to be diluted, proceed as follows:
– Take the measuring cup 21.
– Stir the spray material thoroughly.
– Fill a sufficient quantity of spray material into the spray-
material container 8. (see "Filling in Spray Material",
page 16)
– Dilute the spray material by 10 % with paint thinner.
Examples:
Amount of spray material [ml] 200 300 400 500
Paint thinner [ml]
– Stir the spray material thoroughly.
– Carry out a test-spray run on a test surface.
(see "Spraying", page 16)
When the spraying pattern is perfect, start the spray job.
or
When the spraying result is not satisfactory or when no paint
comes out, please continue as described under "Correction of
Malfunctions" on page 18.
Filling in Spray Material (see figures C1 –C2)
Before any work on the machine itself, pull the mains
plug.
– Unscrew the container 8 from the spray gun.
– Turn the suction tube 10 so that the spray material can be
sprayed with almost no residue:
For spray jobs on horizontal
surfaces/objects
For spray jobs overhead
– Fill the spray material into the container and screw the con-
tainer firmly to the spray gun.

– Avoid interruptions within the spray surface.
Guiding the spray gun evenly will provide uniform surface
quality.
Non-uniform clearance and spray angle lead to heavy forma-
tion of paint mist and thus to an uneven surface.
– End the spraying procedure outside the target area.
Never completely empty the container for the spray material
by spraying. If the suction tube is no longer immersed in the
spray material, the spray jet will be interrupted and this will
result in an inconsistent surface.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.
