DANGER
– Place the appliance on firm surface.
– The high-pressure cleaner must not be
used by children. (Risk of accidents on
account of improper use of the device).
– The device generates a high noise lev-
el. Risk of hearing impairment. Always
use proper hearing protection while
working with the device.
– The water jet coming out of the high-
pressure nozzle causes the gun to re-
coil. Further, an angular spray pipe can
cause additional torque. Hence, hold
the spray lance and gun firmly.
– Never direct the water jet on to persons,
animals, the appliance itself or electrical
components.
– Vehile tyres/ tyre valves may be
cleaned only with a minimum spray dis-
tance of 30 cm. Otherwise, the high
pressure spray can cause damage to
the vehicle tyre/ tyre valve. The discol-
ouring of the tyre is the fhe first sign of
damage. Damaged vehicle tyres are a
source of danger.
– Do not spray materials containing as-
bestos or other health-hazardous sub-
stances.
– The operator must wear proper safety
gear to be protected against the water
sprays.
– Pay attention to ensure that all screws
of all connecting hoses are tightened
properly.
