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 surface.
– The high pressure cleaner must not be
used by children. (Risk of accident on ac-
count of improper use of the appliance).
– 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.
– Do not use the appliance while other
people are present.
– Risk of hearing impairment. Always use
proper ear-protection aids while work-
ing with the appliance.
– Vehicle tyres/ tyre valves may not be
cleaned with this appliance due the high
water pressure.
– Do not spray materials contains asbes-
tos or other health-hazardous sub-
stances.
