Operation
Danger
Lengthy operation of the unit can lead to vi-
bration-related circulatory disturbances of
the hands.
A generally valid use duration cannot be
specified, since this is dependent upon se-
veral influence factors:
– Personal predisposition to bad circulati-
on (frequent suffering from cold fingers,
pins and needles in fingers).
– In low ambient temperatures. Wear
warm gloves to keep hands warm.
– Gripping tightly impedes circulation.
– Continuous operation is more detrimen-
tal than operation interrupted by breaks.
We recommend a medical examination if the
unit is regularly used for extensive, conti-
nuous operation and the corresponding
symptoms (such as, for example, pins and
needles in fingers or cold fingers) are recur-
rent.
Warning
Never operate device with empty fuel tank.
The fuel pump will otherwise be destroyed.
