Bosch Power Tools

The spray surface must be clean, dry and grease-free.

– Roughen smooth surfaces and then remove the sanding dust.

Suitable spray materials and recommended diluting 
agents



When diluting, pay attention that the spray material 
and the diluting agent correspond. 

When using a faulty 

diluting agent, lumps can develop that can lead to clogging 
of the spray gun.

The tool is not suitable for processing dispersion paint (wall 
paint/latex).

Please also observe the practical advice/tips of the spray ma-
terial manufacturers.

Diluting Spray Material

For spray material that needs to be diluted, proceed as follows:

– Take the measuring cup 

21

.

– Stir the spray material thoroughly.
– Fill a sufficient quantity of spray material into the spray-

material container 

8

. (see “Filling in Spray Material”, 

page 16)

– Dilute the spray material by 10 % with paint thinner. 

Examples:

– Stir the spray material thoroughly.
– Carry out a test-spray run on a test surface. 

(see “Spraying”, page 16)

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 C1

–

C2)



Before any work on the machine itself, pull the mains 
plug.

– Unscrew the container 

8

 from the spray gun.

– Turn the suction tube 

10

 so that the spray material can be 

sprayed with almost no residue:

– 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 base unit cannot draw in dust or 
other contamination during operation.



Make sure never to spray on the base unit.

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 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 always 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 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.

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.

Adjusting the Spray Pattern (see figure F)



Never actuate the trigger switch 9 while adjusting the 
air cap 2.

– Loosen the union nut 

3

.

– Turn  the  air  cap 

2

 to the requested position.

– Firmly retighten the union nut.
