– Firstly, carry out a spray test and adjust the spray pattern
and the spray material quantity according to the spray
material.
For adjustments, see the following sections.
– Make sure to hold the spray gun with a uniform clearance
of 20–25 cm vertical to the object being sprayed.
– Begin the spraying procedure outside the target area.
– Move the spray gun evenly horizontally or vertically ac-
cording to the spray pattern configuration.
An even surface quality can be achieved when the spray
paths overlap by 4–5 cm.
– When spraying horizontal objects or spraying overhead,
hold the spray gun at a slight angle and move back from
the sprayed surface.
Risk of tripping! Be aware of potential obstacles.
– Avoid interruptions when spraying the target area.
Guiding the spray gun evenly will provide uniform surface
quality.
A non-uniform spraying angle and distance will lead to heavy
formation of paint mist and consequently 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.
– After breaks or refilling the container (7), check the
nozzle cap (10)/(11)/(12) and the air cap (2) and clean
them if required.
– If spray material settles on the air cap (2) or the nozzle
cap, clean the components with the supplied cleaning
brush (28) or a commercially available washing-up brush.
Setting the spray pattern (see figure I)
Never actuate the trigger switch (5) while adjusting
u
the air cap (2).
– Turn the air cap (2) to the required position.

– Turn the thumbwheel (4) to set the required spray mater-
ial quantity:
Stages 1/2/3: "Wood/glaze/lacquer" application,
Stages 4/5: "Wall" application.
– Start with a spray test at setting 1 and increase the spray
material volume until the required spray pattern is
achieved. If a satisfactory spray pattern is not achieved,
dilute the spray material in 5 % increments (see "Prepar-
ing the spray material", page 23).
Please note: The intensity of the paint application is highly
dependent on the moving speed.
