Proper use
Environmental protection
The packaging material can be recycled. Please
arrange for the environmentally appropriate dis-
posal of the packaging.
Old appliances contain valuable recyclable mate-
rials that should be recycled properly. Batteries
and accumulators contain substances that must
not enter the environment. Please dispose of old
devices and batteries or accumulators in an envi-
ronmentally friendly way.
Cleaning operations which produce oily waste wa-
ter, e.g. engine washes, underbody washes, may
only be carried out using washing stations
equipped with an oil separator.
Work with detergents must only be performed on
liquid-tight work surfaces with a connection to the
sewer system. Do not let release detergent into
waters or earth.
The extraction of water from public waters is pro-
hibited in some countries.
