Serious danger!
Vehicle tyres and tyre valves can be damaged
by the high-pressure jet and become
perforated. The first sign of this is a
discoloration of the tyre. When cleaning them
maintain a distance of at least 30 cm.
Never grasp the power plug with wet hands.
Before each use check the power cord and
power plug for damage. Have a damaged
power cord replaced immediately by an
authorized Kärcher service point or an electrical
specialist.
Before each use check the high-pressure hose
for damage. Replace a damaged high-pressure
hose immediately.

Owing to the water jet emerging from the high-

If necessary wear protective clothing for
