Important information
Availability of the instruction manual
The instruction manual is supplied with the machine.
Keep the instruction manual safe at a suitable place near the machine to have
it at hand in case that you need to look up something.

Proper use
Your bernette machine is conceived and designed for private household use. It
answers the purpose to quilt fabrics as it is decribed in this instruction
manual. Any other use is not considered appropriate. bernette assumes no
liability concerning consequences resulting from an inappropriate usage.
Maintenance of double-insulated products
In a double-insulated product two systems of insulation are provided instead
of grounding. No grounding means is provided on a doubleinsulated product, nor
should a means for grounding be added to the product. Servicing a double-
insulated product requires extreme care and knowledge of the system and should
be done only by qualified service personnel. Replacement parts for a double-
insulated product must be identical to the original parts in the product. A
double-insulated product is marked with the words: “double insulation” or
“double-insulated”.
** The symbol may also be marked on the product.
Protection of the environment**
BERNINA is committed to the protection of the environment. We strive to
minimize the environmental impact of our products by continuously improving
product design and our technology of manufacturing.
The machine is labeled with the symbol of the crossed-out wastebin. This means
that the machine must not be disposed of with the household waste when the
machine is no longer needed. Improper disposal can result in dangerous
substances getting into the groundwater and thus into our food chain, damaging
our health.
The machine must be returned free of charge to a nearby collection point for
waste electrical and electronic equipment or to a collection point for the
reuse of the machine. Information on the collection points can be obtained
from your local administration. When purchasing a new machine, the dealer is
obliged to take back the old machine free of charge and dispose of it
properly.
If the machine contains personal data, you are responsible for deleting the
data yourself before returning the machine.
