Danger of life!
Vehicle tyres/tyre valves may be damaged and burst
by the high-pressure jet. A first sign is the discoloration
of the tyre. Damaged vehicle tyres/tyre valves are
hazardous. Always perform the cleaning with a distance
of at least 30 cm. Never touch the mains plug with wet
hands. Check the power cord and the mains plug for
damages prior to each use of the appliance. If the power
cord is damaged, please arrange immediately for the
exchange by an authorized customer service or a skilled
electrician.
Check the high-pressure hose for damages prior to
each use of the appliance. If the high-pressure hose is
damaged, replace it immediately.

Due to the water jet emerging from the high-pressure
nozzle, a recoil force acts on the trigger gun. Always
ensure a stable standing position and hold the trigger
gun and the spray jet firmly.
If necessary, wear protective clothes for the protection
from return spray.
Water Supply from the Water Main
• Connect a supply hose (not included in the delivery)
to the water connection of the appliance and to the
water supply.
• Open the water supply.
Water Supply from an Open Container
• Unscrew the coupling unit for the water intake.
• Fasten the suction hose with the filter (not included
in the delivery, see "Special Accessories") with screws
on the water connection of the appliance.
• Insert the filter into the container.
• Deaerate the appliance before using it.
• Unscrew the high-pressure line at the high-pressure
connector of the appliance.
• Turn on the appliance and let it run until bubble-free
water emerges at the high-pressure connector.
• Turn off the appliance, and fasten the high-pressure
hose with screws.
Preparing the Appliance
• Insert the mains plug.
• Set the main switch to "I".
Turning On the Appliance
• Press the safety button on the trigger gun, and pull
the lever.
Turning Off the Appliance
• Release the lever.
Press the safety button to prevent the appliance from
being inadvertently turned on during breaks or if you
leave the appliance.
Selecting the Working Pressure
Increasing the working pressure:
Turn the jet spray lance in the "+ + + + + " direction.
Decreasing the working pressure:
Turn the jet spray lance in the "– – – – – " direction.
Adding the Detergent
• Pull the desired length of the detergent suction hose
out of the housing.
• Insert the detergent suction hose into the detergent
container.
• Turn the jet spray lance into the "– – – – – " direction until you
reach the stop.
If detergent has been added:
• Put the detergent suction hose into a container with
clear water, turn on the appliance for approximately
1 minute, and perform a clear rinsing.
