6.1 General information
The mains plug must be disconnected from the
mains socket before carrying out any work on the
machine!
Do not use water or other liquid cleaning agents!
All parts of the housing and operating
components and joints must be cleaned regularly
with dry, clean compressed air, or with a fine
brush or dry, lint-free cloth!
Make sure that the ventilation slits in the housing
are free and clean at all times!
Check the connection cable, mains plug and other
machine components regularly for visual damage

workshop as needed!
All repairs on the machine and any works that
