from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
Do not direct the fine-spray system against yourself,
u
other persons or animals.
Stop spraying if fluid escapes from places other than
u
the intended nozzle during spraying, and restore the
spray gun to its proper condition. There is a risk of elec-
tric shock.
Switching On
– Insert the rechargeable battery.
– Grasp the spray gun by the handle and point it at the tar-
get area.
– Pull the trigger switch (5) on the spray gun.
Switching Off
– Let go of the trigger switch (5).
– Remove the rechargeable battery.
Working Advice
Spraying (see figure C)
Note: Pay attention to the wind direction when you are using
the power tool outdoors.
– 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 fine-spray system with a uniform
clearance of 15–20 cm vertical to the object being
sprayed.
– Begin the spraying procedure outside the target area.
– Move the fine-spray system evenly horizontally or vertic-
ally according 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 fine-spray system 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 fine-spray system 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 (2), check the paint
nozzle (10) and the air cap (3) and clean them if re-
quired.
– If the spray material settles on the air cap (3) or the paint
nozzle, clean the components with a suitable brush or a
damp cloth.

Adjusting the spray pattern
Never actuate the trigger switch (5) while adjusting
u
the air cap (3).
– Turn the air cap (3) to the required position.

(PAINTVolume)
– Turn the thumbwheel (6) to set the required spraying ca-
pacity:
Anticlockwise: Reduces the spraying capacity,
Clockwise: Increases the spraying capacity.
– Start with a spray test with the minimum spray material
volume and increase the volume until the required spray
pattern is achieved. If a satisfactory spray pattern is not
achieved, dilute the spray material in 5 % increments (see
"Preparing the spray material", page 21).
Please note: The intensity of the paint application is highly
dependent on the moving speed.
Too much material on target area
The spray material volume must be re-
duced.
– Turn the thumbwheel (6) anticlock-
wise.
Not enough material on target area
The spray material volume must be in-
creased.
– Turn the thumbwheel (6) clock-
wise.
