Starting Operation
Observe correct mains voltage! The voltage
of the power 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.
Pay attention that the base unit cannot
draw in dust or other contamination during
operation.
Make sure never to spray on the base unit.
Switching On
– Plug the mains plug into a socket outlet.
– Grasp the spray gun by the handle and point
it at the spray surface.
– Firstly, press the On/Off switch 18.
– Pull the trigger switch 9 on the spray gun.
Note: When the base unit is switched on, air al-
ways flows out at the nozzle 11.
Switching Off
– Release the trigger switch 9 and press the
On/Off switch 18.
– Pull the mains plug from the socket outlet.
Working Advice
Spraying (see figures D–E)
Note: Observe the wind direction when operat-
ing the power tool outdoors.
– Firstly, carry out a test-spray run 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 vertical to
the spray object at a uniform clearance be-
tween 5 – 15 cm.
– Begin the spraying procedure outside the tar-
get area.
– Move the spray gun evenly cross-wise or up-
and-down, depending on the spray pattern
setting.
An even surface quality is achieved when the
paths overlap by 4 – 5 cm.
– Avoid interruptions inside the target area.

An even movement of the spray gun results in an
even surface quality.
Non-uniform clearance and spray angle lead to
heavy formation of paint mist and thus to an un-
even surface.
– End the spraying procedure outside the tar-
get area.
Never spray the container completely empty.
When the suction 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 corre-
sponding solvent.
Adjusting the Spray Pattern (see figure F)
Never actuate the trigger switch 9 while ad-
justing the air cap 2.
– Loosen the union nut 3.
– Turn the air cap 2 to the requested position.
– Firmly retighten the union nut.
