Operation
!
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.
!
Danger of injury!
Owing to the water jet emerging from the high-
pressure nozzle a recoil force operates on the
handgun. Ensure you have a secure footing and
hold the handgun and spray lance firmly.
If necessary wear protective clothing for
protection against return spray.
