the permissible minimum capacity is
reached, then the machine can only be
driven and existing lamps can be switched
on. In such a case, the battery monitoring
symbol on the control console glows red.
 Drive the appliance directly to the
charging station; avoid any steep gradi-
ents in the process.
Note:
When using other batteries (e.g. batteries
from other manufacturers), the total dis-
charge protection level for the respective
battery must be reset by the Kärcher after-
sales service.

clothes, rinse immediately with lots of
water.
ATTENTION
Risk of damage!
