ance to the power supply. The plug serves
for the disconnection from the mains.
Use the extension cord that has an ade-
quate cross-section (see "Technical Data")
and unwind it fully from the cable drum.
For connection values, see type plate/tech-
nical data.
HD 7/11-4 Cage:
WARNING
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded.
In case of confusion regarding the power
impedance present on your connection,
please contact your utilities provider.
Water connection
Connection to the water supply
According to applicable regulations,
the appliance must never be used
on the drinking water net without a
system separator. Ensure that the
connection of your building water installation
on which the high-pressure cleaner is operat-
ed is equipped with a system separator pur-
suant to EN 12729 Type BA.
Water that was flowing through a system
separator is considered 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 onto the water
connection.
Note:
The suction hose is not included in the
scope of delivery.
If a suction hose with a check valve or filter
is used, the hose must be filled with water.
 Deaerate the appliance:
Unscrew the nozzle.
Switch on the appliance and let it run
until the water exiting is bubble-free.
At the end let the appliance run for ap-
prox. 10 seconds - then switch off. Repeat
the procedure for a couple of times.
 Switch off the appliance and fit the noz-
zle again.
DANGER
Risk of explosion!
Do not spray flammable liquids.
If the appliance is used in hazardous areas
(e.g. filling stations) the corresponding
safety regulations must be observed.
ATTENTION
Clean engines only at places with correspond-
ing oil separators (environmental safety).
DANGER
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
