hearing protection.
Danger!
!
The unit is not intended for use in potentially
explosive areas. Danger of explosion!
Caution!
Prolonged use of the unit may cause circulatory
problems in the hands due to vibrations.
How long the unit should be used for cannot be specified
as there are several influencing factors:
„ Personal predisposition to poor circulation
(frequently cold fingers, tingling fingers).
„ Low ambient temperature. Wear warm gloves to
protect the hands.
„ A firm grip impedes circulation.
„ Uninterrupted operation is worse than interrupted
operation with breaks.
If the unit is used regularly for long durations and
symptoms recur (e.g. tingling fingers, cold fingers), we
recommend an examination by a doctor.
Caution!
Dispose of detergent residue in an
environmentally friendly manner and according to
regulations.
