Before Use

When buying paints, lacquers and spraying agents,
pay attention to environmental compatibility (for exam-
ple, marked with the blue environmental seal).
Preparing the Spray Material
The spray material should not be too thick, that is, not
exceed the maximum viscosity value of the machine.
Most commercially available paints and lacquers are
primarily suited for applying with a brush. For spraying,
they must be thinned to the required viscosity value.
The spray material and the thinner must be compati-
ble. Information concerning the suitable thinner (wa-
ter, solvent) for each spray material is to be taken from
the manufacturers information. When the wrong thin-
ner is used, lumps can form that clog the machine.
First, mix the spray material thoroughly and bring to a
average room temperature (20–22 °C). Do not change
the viscosity by additional heating.
Dip the metering cup 12 provided into the spray mate-
rial until it is brim full. Lift the metering cup out of the
spray material and allow the fluid to run out (see Fig.
). Measure the time required in seconds until the
A
flow is no longer continuous. This time is called the
"DIN-seconds (DIN-s)".
When the value is too high, add the thinning agent that
is suitable for the spray material in steps and mix well.
Again measure the DIN-seconds. Repeat the process
until the value given in the table is reached.
The table below gives examples of materials and DIN
standard values:
Spray Material
Car body enamel
Bronze
Primer
Acrylic/synthetic-resin varnish
Wood preservation
Scumble glaze
Hammered effect enamel
Dispersion paint
* Products containing granules or particles must not
be sprayed. These act abrasively and shorten the
service life of the pump and valve.
In this case, claims for repair/replacement of these
parts are voided.

Preparing the Surface to be Sprayed
The surface to be sprayed must be clean, dry and free
of grease. Roughen smooth surfaces and then re-
move the sanding dust.
The spraying mist can soil the surroundings. There-
fore, adequately cover the surroundings of the surface
to be sprayed.
Spraying work on the banks of lakes or streams or in
the surrounding areas of their immediate feeding zone
is not allowed.

Putting into Operation

Ensure that the mains voltage is correct!
The voltage of the power source must agree with the
value given on the nameplate of the machine. Ma-
chines designated for 230 V can also be operated with
220 V.
To Put into Operation, turn the regulating knob 3
counterclockwise completely to the left. Press the
on/off switch 4.
Turn the regulating knob 3 in the clockwise direction
until the spray cone has the desired width and the
spray mist is uniformly fine and without drops (see
Fig. ).
B
To Switch off, release the on/off switch 4.
For each repeated switching on, turn the regulating
knob 3 completely to the left.

Working Instructions

Spraying Operation
Before the spraying procedure, briefly spray the same
material that is used for thinning into a collection basin.
Fill the prepared spray material into the container 5
through the funnel strainer (accessory).
Always screw the container 5 firmly onto the pump
unit 7.
Do not switch the machine on and off over the surface
to be sprayed.
Always hold the machine upright. As necessary, use a
nozzle extension (accessory) and bend the nozzle in
the desired direction.
Make a trial spraying onto cardboard or paper.
The distance of the nozzle to the work piece is de-
pendent on the spray material (approx. 20 to 35 cm
spraying distance depending on the spray cone and
the desired material application). Determine the ap-
propriate distance to the surface to be sprayed in each
case by a trial. Start with a greater distance.
