Guarantee

The guarantee conditions of our German companies do not
apply to appliances acquired outside of Germany. In countries
where our subsidiaries sell our products a guarantee can only
be issued by those subsidiaries. Such guarantee is only grant-
ed if the subsidiary has issued its own terms of guarantee. No
other guarantee will be granted.
We shall not provide any guarantee for appliances acquired in
countries where we have no subsidiary to sell our products.
This will not affect warranties issued by any importers.

Environment and recycling

We would ask you to help protect the environment. After use,
dispose of the various materials in accordance with national
regulations.
