The spray mist contaminates the environment. When spray-
ing in enclosures, surfaces not covered can become contami-
nated.
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
f
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.
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 fol-
lows:
– Take the measuring cup 22.
– Stir the spray material thoroughly.
– Fill a sufficient quantity of spray material into the spray-
material container 11. (see “Filling in Spray Material”,
page 17)
– Dilute the spray material by 10 % with paint thinner. Ex-
amples:
– Stir the spray material thoroughly.
– Carry out a test-spray run on a test surface. (see “Spray-
ing”, page 17)
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 19.
Filling in Spray Material (see figures B1–B2)
f
Before any work on the machine itself, pull the mains
plug.
– Unscrew the container 11 from the spray gun.
– Turn the suction tube 10 so that the spray material can be
sprayed with almost no residue:
– Fill the spray material into the container and screw the con-
tainer firmly to the spray gun.
Starting Operation
f Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
f Pay attention that the power tool cannot draw in dust
or other contamination during operation.
Switching On
– Plug the mains plug into a socket outlet.
– Grasp the power tool and point it at the spray surface.
The power tool is equipped with a two-step trigger switch 16.
The first step starts the turbine. The second step transports
the spraying material.
– Pull the trigger switch 16 until spraying material starts to
come out.
Switching Off
– Release the trigger switch 16.
– Pull the mains plug from the socket outlet.
Working Advice
Spraying (see figures C–D)
Note: Observe the wind direction when operating the power
tool outdoors.
– Firstly, carry out a test-spray run and adjust the spray pat-
tern and the spray material quantity according to the spray
material. (For adjustments, see the following sections)
– Make sure to hold the spray gun vertical to the spray object
at a uniform clearance between 5 – 15 cm.
– Begin the spraying procedure outside the target area.
– Move the spray gun evenly cross-wise or up-and-down, de-
pending on the spray pattern setting.
An even surface quality is achieved when the paths overlap
by 4 – 5 cm.
– 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 spray the container completely empty. When the suc-
tion tube no longer immerses in the spray material, the spray
jet will break off, resulting in a non-uniform surface.
When coating material builds up on the nozzle and air cap,
clean both parts with the corresponding solvent.
Note: Only place down the power tool on a level and clean sur-
face so that it can not tip over.
