ning over, pinching, dragging or similar.
Protect the power cable from heat, oil,
and sharp edges.
„
The connection between the power cable
and extension cable must not lie in water.

ing area must be protected against jet
water.
„ The appliance may only be connected
to an electrical supply which has been
installed in accordance with IEC 60364.
„ The appliance may only be connected
to alternating current. The voltage must
correspond with the type plate on the
appliance.
„ The minimum fuse rating required at the
socket outlet is 13 A (slow-blow).
„ To avoid accidents due to electrical
faults we recommend the use of sock-
ets with a line-side current-limiting cir-
cuit breaker (max. 30 mA nominal
tripping current).
„ The plug and coupling of the extension
cable used must be watertight.
„ Always fully unroll electrical cables from
the cable drum.
„ This appliance was designed to be
used with detergents which are sup-
plied or recommended by the manufac-
turer. The use of other detergents or
chemicals may compromise the safety
of the appliance.
Safety devices serve to protect the user
and must not be rendered inoperational or
their functions bypassed.
The switch prevents unintented starting of
the appliance. Stop the appliance during
breaks or after operation.
The safety catch on the trigger gun pre-
vents the appliance from being switched on
unintentionally.
The high pressure hose is specially con-
structed with reinforced walls to handle wa-
ter pressure up to 16 MPa (2700 psi) - it is
easily damaged and should be stored care-
fully.
„
Do not kink.
„ Do not drive vehicles over the hose.
„ Do not expose the hose to sharp edges
or corners.
Misuse will lead to ballooning or premature
failure and will invalidate warranty.
