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 18.
Filling in Spray Material (see figures B1 –B2)
 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:
For spray jobs on horizontal
surfaces/objects
For spray jobs overhead
– Fill the spray material into the container and screw the con-
tainer firmly to the spray gun.

Starting Operation

 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.
 Pay attention that the power tool cannot draw in dust
or other contamination during operation.
Switching On
To save energy, only switch the fine-spray system on when
you are using it.
– 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)
– Be absolutely sure to hold the spray gun at a consistent dis-
tance of 5 –15 cm perpendicular to the spray object.
– 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.
Bosch Power Tools
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 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.
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-
toward the front in nozzle
face so that it can not tip over.
