Safety instructions
WARNING
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
Boiler
Note: With especially hard water, calcium
can be flocculated at a higher rate inside
the boiler. This is a natural phenomenon
and it does not impact the function of the
appliance, so long as the maintenance in-
tervals are adhered to (see "Care and
Maintenance").
