Power Connection; Operation; Operating Modes - Kärcher HDS 13/20-4 SX Handbuch

Replug the rinse line of the detergent
dosing valve.
Connect suction hose (minimum diame-
ter 3/4") with filter (accessory) to the
water connection point.
– Max. suck height: 0.5 m
Until the pump sucked in water, you should:
Set the pressure/quantity regulation at
the pump unit to maximum quantity.
Close the dosing valve for the deter-
gent.
Danger
Never suck in water from a drinking water
container. Never suck in liquids which con-
tain solvents like lacquer thinner, petrol, oil
or unfiltered water. The sealings within the
device are not solvent resistant. The spray
mist of solvents is highly inflammable, ex-
plosive and poisonous.

Power connection

– For connection values, see technical
data and type plate.
– The electrical connections must be
done by an electrician according to IEC
60364-1.
Caution
The maximum tolerable mains impedance
at the electrical contact point (see Techni-
cal Data) must not be exceeded.
If you have to use an extension chord,
then the same must always be rolled up
and have an adequate cross-section.

Operation

Caution
Never operate device with empty fuel tank
The fuel pump will otherwise be destroyed.
Safety instructions
Warning
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 sev-
eral 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 occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
