Maintenance and Service
Maintenance
u Stop, remove plug from the power supply and disconnect
from water supply.
Note: To ensure long and reliable service, carry out the fol-
lowing maintenance regularly.
Having two filters (internal and external) increases the pro-
tection from debris entering the machine and therefore ex-
tending product life.
Ensure both filters are kept clean and clear of debris at all
time.
Regularly check for obvious defects such as loose fixings,
and worn or damaged components.
Check that covers and guards are undamaged and correctly
fitted. Carry out necessary maintenance or repairs before
using.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
