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 must be 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.
For safety reasons, we recommend that you operate the appliance
only via a residual current device (max. 30mA).
An unsuitable electrical extension cable 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 electrical extension cable can be hazardous.
