When spraying, all non-covered surfaces can be contamin-
ated by the spray mist. Therefore, thoroughly prepare the
area around the surface to be sprayed:
– Carefully cover floors, furnishings, doors, windows as
well as door and window frames, etc. Painting substrate,
for example, is recommended for covering the floors.
– Fix the cover material in place. Cover material that is not
fixed in place securely can be detached or blown away by
the powerful air jet.
Carefully mask off plug sockets and switches. Un-
u
covered plug sockets and switches may cause a short-cir-
cuit and increase the risk of electric shock.
Preparing the spray material
– Stir the spray material thoroughly.
Using spray material at room temperature will yield a bet-
ter spray pattern.
– Dilute the spray material if necessary.
If the spray test does not produce a good spray pattern,
dilute in 5 % increments until an optimal spray pattern is
achieved.
Spray material
Wood preservatives, oils, glazes, impreg-
nations, water
Solvent-dilutable or water-dilutable (re-
commended) lacquers, primers, anti-rust
primers, radiator lacquers, thick-coat
glazes
Emulsion paints and latex paints (interior
wall paints)
When diluting, make sure that the spray material and
u
the diluting agent are compatible. When using a faulty
diluting agent, lumps can develop that can lead to clog-
ging of the spray gun.
When diluting the spray material, make sure that the
u
flash point of the mixture is above 55 °C again after di-
luting. Diluting substances such as solvent-based lac-
quers lowers the flash point.
Note the specifications of the paint manufacturer re-
u
lating to sprayability, e.g. in the technical information
sheet or data sheet. Make sure that you do not spray
any paints that are not suitable according to the man-
ufacturer's specifications.
Filling the spray material (see figures C1–C2)
Note: Remove the air hose (20) before pouring in spray ma-
terial (quarter turn of the bayonet lock (21) anticlockwise;
pull the bayonet lock (21) out of the port (9)).
– When using large buckets, pour the spray material into a
smaller transfer bucket (14) if necessary (e.g. 10 l wall
paint into an empty 2.5 or 5.0 l bucket).
– Hold the spray gun in place with one hand and
use the other hand to turn the container (7)
towards the open symbol.
– Pull the spray gun off the container (7).
Bosch Power Tools
– If you are using already opened spray material, place the
thoroughly cleaned filling sieve (13) on the container (7)
to hold back any lumps of paint when pouring in.
– Pour the spray material into the container (7) up to no
more than the 1000 mark.
– Put the spray gun on the container (7). Turn
the container (7) towards the close symbol
until you hear the lock ring (6) engage.
– Carry out a test-spray run on a test surface.
If the spray pattern is optimal, you can begin spraying.

Starting Operation

Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Make sure that the base unit cannot draw in dust or
u
other contamination during operation.
Recommended Make sure never to spray on the base unit.
u
dilution
Stop spraying if fluid escapes from places other than
u
0 % the intended nozzle during spraying, and restore the
spray gun to its proper condition. There is a risk of elec-
tric shock.
0–5 %
Do not direct the fine-spray system against yourself,
u
other persons or animals.
Switching on (see figure D)
At least 5 %
– Check whether the correct nozzle cap is fitted. (see
"Changing the nozzle cap (see figures B1–B2)", page 22)
– Plug the mains plug into a plug socket.
– Grasp the spray gun by the handle and point it at the tar-
get area.
– Switch on by pressing the on/off button (25).
– Set the on/off button (25) to the required application to
regulate the air flow (see "Setting the air flow (see
figure D)", page 24).
– Pull the trigger switch (5) on the spray gun.
Note: Air always flows out at the air cap (2) when the base
unit is switched on.

Switching off

– Let go of the trigger switch (5) and switch off by pressing
the on/off button (25).
– Pull the mains plug from the plug socket.

Spraying (see figures E–H)
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.
