Danger
– Place the appliance on firm surface.
– The high pressure cleaner must not be
used by children. (Risk of accident on
account of improper use of the appli-
ance).
– The high pressure spray generates high
levels of noise when the appliance is in
use. Risk of hearing impairment. Al-
ways use proper ear-protection aids
while working with the appliance.
– 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 pipe and gun firmly.
– Never direct the water jet on to persons,
animals, the appliance itself or electrical
components.
– Vehicle 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.

tos or other health-hazardous sub-
stances.
