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!
Quality requirements for water:
For connection values, see type plate/tech-
nical data.
Use a fibre-reinforced hose (not includ-
ed in standard delivery).
Diameter should be minimum 1".
Connect the hose to the water connec-
tion of the appliance.
Connect the hose to the water tap.
A prepressure pump must be connected in
front of the appliance to suction waer.
ƽ
Danger
Never suck in water from a drinking water
container.
ƽ
Danger
Never draw in fluids containing solvents or
undiluted acids and solvents! This includes
petrol, paint thinner and heating oil. The
spray mist thus generated is highly inflam-
mable, explosive and poisonous. Do not
use acetone, undiluted acids and solvents
as they are aggressive towards the materi-
als from which the appliance is made.
Connect the water connection of the ap-
pliance to the prepressure pump (suita-
ble hose: 4.440-270.0).
Remove air from appliance before oper-
ation.
Open the water supply.
Unscrew the nozzle.
Press the lever on the hand spray gun.
Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
Switch on the appliance and let it run
until the water exiting from the spray
pipe is bubble-free.
Switch off the appliance and fit the noz-
zle again.

Danger
–
The appliance may not be used in areas
where a risk of explosion is present.
–
Place the appliance on firm, even sur-
face.
–
The high pressure cleaner must not be
used by children. (Risk of accident on
account of improper use of the appli-
ance).
–
The water jet coming out of the high
pressure nozzle causes the gun to re-
coil. Further, an angular spray pipe can
cause additional torque. Hence hold the
spray pipe and gun firmly.
–
Never direct the water jet on to persons,
animals, the appliance itself or electrical
components.
–
Risk of injury on account of high pres-
sure water jet and mobilised dust. Wear
protective glasses, protective gloves, a
protective suit, special safety boots and
a middle foot protection.
–
The jet must not be directed by the user
at him/herself or at other persons to
clean clothing or footwear.
