ponents.
High-pressure jets can be dangerous if
improperly used. The jet may not be di-
rected at persons, animals, live electri-
cal equipment or at the appliance itself.
The high-pressure jet must not be di-
rected at other persons or the user him-
/herself to clean clothing or footwear.
Vehicle tyres/tyre valves are suscepti-
ble to damage from the high-pressure
jet and may burst. The first indication for
this is a discolouration of the tyre. Dam-
aged vehicle tyres/tyre valves are peril-
ous. Keep a minimum jet distance of
30 cm during cleaning!
몇WARNING
Do not use the appliance when there
are other persons around unless they
are also wearing protective clothing.
The appliance must not be operated by
children or persons who have not been
instructed accordingly.
This appliance is not intended for use
by persons with limited physical, senso-
ry or mental capacities or lacking expe-
rience and/or skills, unless such per-
sons are accompanied and supervised
by a person in charge of their safety or
they have received precise instructions
on the use of this appliance and have
understood the resulting risks.
Children must not play with this appli-
ance.
Supervise children to prevent them
from playing with the appliance.
몇CAUTION
Create stability for the appliance prior to
any work on or with the appliance to
prevent accidents or damage.
The water jet that is emitted from the
high-pressure nozzle results in a repul-
sion power acting on the hand spray
gun. Make sure that you have a firm
footing and are also holding the hand
spray gun and spray lance firmly.
Never leave the appliance unattended
as long as it is in operation.
ATTENTION
In case of extended breaks, switch off

explosive atmospheres.
Never use the appliance to clean ob-
jects containing hazardous substances
(e.g. asbestos).
Do not spray flammable liquids.
Never draw in fluids containing solvents
or undiluted acids and solvents! This in-
cludes petrol, paint thinner and heating
oil. The spray mist is highly inflamma-
ble, explosive and poisonous. Do not
use acetone, undiluted acids and sol-
vents, as they corrode the materials
used on the appliance.
Keep packaging films away from chil-
dren, there is a risk of suffocation!
몇WARNING
According to applicable regulations, the
appliance must never be used on the
drinking water net without a system
separator. Ensure that the connection
of your building water installation on

ers aerosols can develop. Inhaling aer-
osols can cause health damage.
–Depending on the application, com-
pletely shielded nozzles (e.g. surface
cleaner) that significantly reduce the
emission of aqueous aerosols can be
used for high-pressure cleaning.
–The use of such shielding is not possi-
ble with all applications.
–If the use of a completely shielded noz-
zle is not possible, a respirator of the
category FFP 2 or the like should be
