5. Operation
– The appliance must not be left unatten-
ded during operation.
– Ensure that the appliance is situated
on firm ground.
– Provide adequate ventilation when
operating the appliance in rooms
(danger of poisoning).
– The appliance must not be installed in
damp rooms or in rooms with an
aggressive atmosphere.
– The water jet emerging from the high-
pressure nozzle causes the gun to
recoil. An angular spray lance will also
cause a torque. Therefore, grip the
spray lance and gun firmly.
– Never direct the water jet at people,
animals, the appliance or electrical
components.
– The high-pressure cleaner must not
be operated by children (danger of
accidents caused by improper use of
the appliance).
– Vehicle tyres/tyre valves may only be
cleaned at a minimum distance of 30
cm. Otherwise the vehicle tyres/tyre
valve may be damaged by the high-
pressure jet. The first indication of
damage is discolouration of the tyre.
Damaged vehicle tyres can be highly
dangerous.
– Materials containing asbestos and
other substances which are detrimental
to health must not be sprayed down.
– Suitable protective clothing should be
worn to protect the operator from back-
spray.
– Always ensure that all connecting
hoses are securely screwed on.
– The gun trigger must not be clamped
when operating the appliance.
– The exhaust opening must not be
blocked.
– Do not bend over or touch the inside of
the exhaust opening when operating
with hot water/steam (danger of burns).
5.1 Venting the appliance
•••••
Open the water intake.
•••••
Allow the appliance to run without the high-
pressure hose until the water emerges without
bubbles.
•
Then connect the high-pressure hose.
•
If the spray lance and high-pressure nozzle
have already been fitted to the high-pressure
hose, you can vent the appliance as follows:
With the hand-held spray gun open, switch
the appliance on and off several times at
intervals of 10 seconds until the water emerges
from the high-pressure hose without bubbles.
5.2 High-pressure nozzle
•••••
The effectiveness of the high-pressure jet
depends to a great extent on the spray angle.
A 20 degrees fan jet nozzle is usually employed
(included in standard delivery).
•••••
Other nozzles are available as accessories.
0° full jet nozzle
for stubborn dirt.
40° fan jet nozzle
for sensitive surfaces.
Dirt blaster
for thick layers of dirt.
Variable angle nozzle
with adjustable spray angle
•
At first always direct the high-pressure jet
from a greater distance at the object which is
to be cleaned, thereby preventing damage
from excessive pressure.
