Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.

Thoroughly clean the individual parts of the fine-spray
system immediately after each use, especially all
paint-carrying components.
Proper cleaning is a pre-
requisite for faultless and safe operation of the spray gun.
No warranty claims will be accepted if cleaning has not
been done at all or has not been done properly.
