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.

Note

Take the foot off the aceelerator pedal, 

press the emergency-stop button to imme-

diately deactivate all functions and turn the 

key switch to the "0" position.
