Operation

Danger
– Place the appliance on firm surface.
– The high pressure cleaner must not be
used by children. (Risk of accident on ac-
count of improper use of the appliance).
– 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 recoil.
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 pres-
sure spray can cause damage to the
vehicle tyre/ tyre valve. The discolouring
of the tyre is the fhe first sign of damage.
Damaged vehicle tyres are a source of
danger.

tos or other health-hazardous substanc-
es.
