Symbols on the machine

High-pressure jets can be dan-
gerous if improperly used. The
jet may not be directed at per-
sons, animals, live electrical equipment or
at the appliance itself.
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!

Safety Devices

Safety devices serve for the protection of the
user and must not be put out of operation or
bypassed with respect to their function.
Overflow valve
If the hand spray gun is closed, the over-
flow valve opens and the high pressure
pump diverts the water back to the pump
suction side. Thus the permissible working
pressure is not exceeded.
The overflow valve is set by the manufac-
turer and sealed. Setting only by customer
service.
