– Remove the container (7) from the spray gun (1)and
empty it completely into a sealable material tin.
– Remove the cap nut (3), the air cap (2), the gasket (11)
and the nozzle cap (9) with the O-ring (10) and the suc-
tion tube (12) with the container seal (14).
When doing so, ensure that the O-ring (10) remains on
the nozzle cap.
– Clean all paint-carrying parts in a bucket with diluting
agent using a commercially available washing-up brush.
Also clean the paint channel (16) of the spray gun (1).
– Check that the suction tube (12) and the container
seal (14) are free of spray material and undamaged.
If required, clean the container seal (14) again with dilut-
ing agent.
– Clean the ventilation hole (15) using an appropriate
cleaning brush.
– Allow all components to dry thoroughly before assem-
bling them.
– Reassemble the fine-spray system in reverse order.
Slide the container seal (14) upwards again into the
groove of the suction tube (12).
Ensure that the container seal is positioned precisely all
around in the suction tube groove in order to seal the
spray gun correctly.
Make sure that you slide the suction tube (12) all the way
back onto the paint channel (16).
Cleaning the air filter (see figure I)
The air filter (28) must be cleaned occasionally. The air filter
must be replaced if it is heavily contaminated.
– Open the air filter cover (23).
– Remove the air filter (28).
– Light contamination:
Knock on the air filter (28).
Troubleshooting
Problem
Cause
Spray material does not
Spraying capacity too low
cover properly
Clearance to target area too large
Not enough spray material on target area, too
few spray paths sprayed over target area
Spray material too viscous
Spray material runs off after
Too much spray material applied
coating
Clearance to target area too close
Viscosity of spray material too low
Spray material applied too often over same
spot
Atomisation too coarse
Spraying capacity too high
Nozzle needle (13) contaminated
Spray material too viscous
Air filter (28) heavily contaminated
Bosch Power Tools
or
Heavy contamination:
Clean the air filter (28) under running water and sub-
sequently leave it to dry thoroughly, in order to prevent
mould from forming.
or
Replace the air filter (28).
– Reinsert the air filter.
– Close the air filter cover (23) again.
Never use the fine-spray system without air filter. Dirt
u
particles may get into the motor compartment and dam-
age it.
Material Disposal
Contaminated diluting agent, remnants of spray material
and, if applicable, remnants of diluting agent must be dis-
posed of properly and in an environmentally friendly man-
ner. Observe the manufacturer's disposal information and
the local regulations for disposal of hazardous waste.
Chemicals harmful to the environment may not be disposed
of into soil, groundwater or bodies of water. Never pour
chemicals harmful to the environment into the sewerage sys-
tem.
Storage
– Before putting the fine-spray system into storage, thor-
oughly clean the fine-spray system and allow all parts to
dry completely before assembling them.
If the fine-spray system is not being used, the elastic band
together with the pin on the base unit (19) serve as a prac-
tical storage option for the air hose (17) (see figure ).
If the fine-spray system is not being used, the elastic band

Corrective measures
Turn the thumbwheel (5) in the + direction
Reduce spray distance
Apply more spray paths over target area
Dilute the spray material again and carry out a
test-spray run
Turn the thumbwheel (5) in the − direction
Increase spray distance
Add original spray material
Remove spray material; reduce number of
spray paths over same spot
Turn the thumbwheel (5) in the − direction
Clean the nozzle needle
Dilute the spray material again and carry out a
test-spray run
Change the air filter
