Water connection

Connection to the water supply
Warning
Observe regulations of water supplier.
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!
For connection values refer to technical
specifications
 Connect the supply hose (minimum
length 7.5 m, minimum diameter 3/4") to
the water connection point of the ma-
chine and at the water supply point (for
e.g. a tap).
Note
The supply hose is not included.
 Open the water supply.

Drawing in water from open reservoirs

 Screw the suction hose with filter (order
no. 4.440-238.0) to the water connection.
 Deaerate the appliance:
Unscrew the nozzle.
Switch on the appliance and let it run
until the water exiting is bubble-free.
 Switch off the appliance and fit the noz-
zle again.
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 fingertight.
Risk of explosion!
Do not spray flammable liquids.
If the appliance is used in hazardous areas
(e.g. filling stations) the corresponding
safety provisions must be observed.
Warning
Clean engines only at places with corre-
sponding oil separators (environmental
safety).

High pressure operation

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 hand-spray 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.
