Maintenance

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 us-
ing.

be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
