Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
Cleaning (see figures I–K)
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
with the respective diluting agent (paint thinner
or water) for the spray material being used.
Never immerse the complete spray gun into the
cleaning agent.
Never clean the nozzle and air holes of the spray
gun with pointed metal objects.
Do not pour diluted spray material back into the
original spray material drum/tin for storage.
Clean the spray gun thoroughly after having
sprayed material hazardous to one's health.
– 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 8 and empty the re-
maining spray material.
– Fill diluting agent (paint thinner or water) in-
to the container and screw it to the spray
gun.
– Shake the spray gun several times.
– Switch the base unit on and spray the dilut-
ing agent into an empty material tin.
– Repeat the last three steps until clear dilut-
ing agent emerges from the spray gun.
– Switch the base unit off again.

seal 10 is free of spray material and undam-
aged.

Bosch Power Tools
From time to time, the nozzle seal 12 must also
be cleaned.
– Remove the nozzle 11 and the nozzle seal 12.
If required, use a pointed object, as the noz-
zle seal is seated firmly to the spray gun.
– Clean the nozzle seal with diluting agent.
– Reinstall the nozzle seal in the spray gun. Pay
attention that the groove points away from
the spray gun.
– Mount the nozzle onto the spray gun body
and turn it to the correct position.
