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.
