Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains
plug.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Cleaning the Spray Gun (see figure I)
Proper cleaning is the requirement for flawless operation of
the spray gun. Improper or lack of cleaning voids warranty
claims.
Always clean the spray gun and the container for the spray
material with water.
Never immerse the complete spray gun in water.
Never clean the nozzle and air holes of the spray gun with
pointed metal objects.
– Switch the base unit off and pull the trigger switch 9 of the
spray gun so that the spray material can flow back into the
container.
– Unscrew the container 10 and empty the remaining spray
material.
– Fill water into the container and screw it to the spray gun.
– Shake the spray gun several times.
– Switch the base unit on and spray the water into a suitable
collecting container (e.g. a bucket).
– Repeat the last three steps until only clear water comes out
of the spray gun.

free of spray material and undamaged.
– Clean exterior parts of the container and the spray gun
with a moist cloth.
– Unscrew the adjusting ring 4, the union nut 5, the air cap 3
and the rotating ring 14.

ter.
– Mount the nozzle cap 15 to the spray gun body and turn it
to the correct position.
– Mount the rotating ring 14 and the air cap 3 to nozzle cap

Changing the Air Filter (see figure J)
The air filter must be replaced when soiled.

– Remount the air filter cover.
Cleaning the Nozzle Seal (see figure K)
The nozzle seal 17 must be cleaned occasionally.
– Remove the nozzle cap 15 and the nozzle seal 17.
If required, use a pointed object, as the nozzle seal is seat-
ed firmly to the spray gun.
– Clean the nozzle seal with water.
– Reinstall the nozzle seal in the spray gun. Pay attention that
the groove points away from the spray gun.
Material Disposal
Paint and dried paint remainders must be disposed of in an
environmentally-friendly manner. Observe the manufactur-
er's instructions for disposal and the local regulations for haz-
ardous waste disposal.
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!
Cause
Spraying capacity too low
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
Too much spray material applied
Clearance to target area too close
Viscosity of spray material too low
Spray material applied too often over same
spot
Corrective Measure
Turn thumbwheel 7 in direction IIII
Reduce spray distance
Apply more spray paths over target area
Dilute the spray material again and carry out
a test-spray run
Turn thumbwheel 7 in direction I
Increase spray distance
Add original spray material
Remove spray material; reduce number of
spray paths over same spot
