Only Xpert HD 7125...:
Danger
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.
