Unpacking the appliance
• • • • •
Please contact your dealer immediately if, on
unpacking the appliance, you discover damage
has been caused during transportation.

Do not simply discard the packing materials
with the house-hold waste. Take the packing
materials to the appropriate collection areas for

1. Starting
Electrical Connection
• • • • •
See technical data of connected values.
• • • • •
Check whether the voltage shown on the rating
plate corresponds to that of the power source.
Note: If you are using an extension cable, it
should always be completely unwound from the
cable drum and have a sufficient cross-sectional
area: 10 m = 1.5 mm², 30 m = 2.5 mm²
Water Connection
• See technical data for connected values.
• Screw the coupling (supplied with the machine)
onto the inlet water connection of the machine.
• Connect a water supply hose to the machine using
a suitable hose connector to match the coupling on
the machine (hose and connector not supplied).
Suction
Observe the following if you are drawing water
from an open container:
1. Unscrew the union element from the water
connection of the appliance, and attach a suc-
tion hose with filter (order no. 4.440-570) direct-
ly to the appliance.
2. Allow the pump to operate without the high-
pressure hose until water appears at the high-
pressure outlet without any more bubbles.
3. Then re-attach the high-pressure hose.
Note:
Dirt in the feed water could lead to the appliance
being damaged. To avoid this risk, we recom-
mend fitting a filter. A suitable filter with 3/4" con-
nection is available under Order No. 4.730-059.
