Water connection

Connection to the water supply
WARNING
Observe regulations of water supplier.
According to applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. A suit-
able system separator by KÄRCHER or al-
ternatively a system separator according to
EN 12729 type BA must be used.
Water that was flowing through a system
separator is considered non-drinkable.
CAUTION
Always connect the system separator to
the water supply, never directly to the appli-
ance!
For connection values refer to technical
specifications
 Connect the supply hose (minimum
length 7.5 m, minimum diameter 1") to
the water connection point of the appli-
ance (such as the tap).
Note:
The supply hose is not included.
ATTENTION
Risk of damage due to cavitation. Do not
draw water. Always supply appliance with
pressure water.
 Open the water supply.

Operation

DANGER
Risk of injury! Never use the appliance
without the spray lance attached. Check
and ensure proper fitting of the spray lance
prior to each use. The screw connection of
the spray lance must be finger-tight.
Risk of explosion!
Do not spray flammable liquids.
If the appliance is used in hazardous areas
(e.g. filling stations) the corresponding
safety regulations must be observed.

CAUTION
Environmental damage. Clean motors at plac-
es with a corresponding oil separator only.
High pressure 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 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.
Note:
The appliance is equipped with a pressure
switch. The motor starts up only when the
lever of the pistol is pulled
 Roll off the high pressure hose totally
from the hose drum.
 Set the appliance switch to "I".
Control lamp glows green.
 Unlock the trigger gun and pull the lever
of the gun.
DANGER
When adjusting the pressure/quantity regu-
lation, make sure that the screw connection
of the spray lance does not become loose.
 Set working pressure and flow rate
through turning (runless) at the pres-
sure- and amount regulation (B) (+/-).
 For transporting small quantities, the
engine heat ensures that water is heat-
ed up to approx. 15 °C.

Interrupting operation

 Release the lever of the trigger gun; the
device will switch off.
 Release again the lever of the trigger
gun; the device will switch on again.
