Electriccomponents
DANGER
Risk of electric shock.
Never touch the mains plug and the
socket with wet hands.
Check the power cord with mains Plug
for damage prior to every use. Do not
use the machine if a supply cord or
important parts of the machine are
damaged, e.g. safety devices, high
pressure hoses, trigger gun.
All current-conducting parts in the
working area mustbe protected against
jet water.
The mains plug and the coupling of an
extension cable must be watertight and
must never lie in water. Moreover, the
coupling may never lie on the ground.
The use of cable reels that ensure that
the sockets are at least 60 mm above
the ground is commended.
Make sure that the power cord or
extension cable is not damaged by
running over, pinching, dragging or the
like. Protect the power cords from heat,
oil, and sharp edges.
Always switch off the mains
disconnecting switch when leaving the
appliance unattended.
WARNING
The appliance may only be connected
to an electric supply that has been
installed by an electrician in
accordance with IEC 60364.
The appliance may only be connected
to alternate current. The voltage must
correspond with the type plate of the
appliance.

2
For safety reasons, we recommend
that you operate the appliance only via
a residual current device (max. 30mA).
An unsuitable electricalextensioncable
can be hazardous. Only use an
electrical extension cable which has
been approved and labeled for this
purpose and has an adequate cable
cross-section outdoors: 1 - 10 m: 1.5
mm2;10 - 30 m: 2.5 mm2
Always fully unreel the extension cable
from the cable drum.
An unsuitable electricalextensioncable
can be hazardous.
