Operation; Turning On The Appliance - Kärcher HDS 551 C Eco Betriebsanleitung

Operation

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 sever-
al 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 occurrence
of the symptoms (e.g. cold, numb fingers)
please consult a physician.
Warning
Never operate device with empty fuel tank
The fuel pump will otherwise be destroyed
