Operation With Detergent - Kärcher HDS 551 C Eco Original Instructions Manual

operation time, since this depends on sev-
eral factors:

–
cies (cold, numb fingers).

–
gloves to protect hands.
A firm grip impedes blood circulation.

rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
