CAUTION
 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 repulsion 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 the appli-
ance at the appliance switch.
 Do not operate the appliance at temperatures be-
low 0 °C.

Other risks

DANGER
 The appliance may not be operated in explosive at-
mospheres.
 Never use the appliance to clean objects contain-
ing hazardous substances (e.g. asbestos).
 Do not spray flammable liquids.
 Never draw in fluids containing solvents or undilut-
ed acids and solvents! This includes petrol, paint
thinner and heating oil. The spray mist is highly in-
flammable, explosive and poisonous. Do not use
acetone, undiluted acids and solvents, as they cor-
rode the materials used on the appliance.
 Keep packaging films away from children, there is
a risk of suffocation!
WARNING
According to applicable regulations, the appliance

must never be used on the drinking water net with-
out a system separator. Ensure that the connection
of your building water installation on which the
high-pressure cleaner is operated is equipped with
a system separator pursuant to EN 12729 Type
BA.
 Water that has flown through a system separator is
no longer classified as drinking water.
 High-pressure hoses, fixtures and couplings are
important for the safety of the appliance. Only use
high-pressure hoses, fixtures and couplings rec-
ommended by the manufacturer.
When disconnecting the supply or high pressure

hose, hot water may leak from the connections af-
ter operation.
CAUTION
 Mind the weight of the appliance when selecting
the storage location and during transport (see tech-
nical data) to prevent accidents or injuries.
Working with detergent
WARNING
 This appliance was designed to be used with deter-
gents which are supplied or recommended by the
manufacturer. The use of other detergents or
chemicals may compromise the safety of the appli-
ance.
 The improper use of detergents can cause severe
injuries or toxication.
Store detergents away from the reach of children.


Personal protective equipment

CAUTION
 Wear protective clothing and safety goggles to pro-
tect against splash back containing water or dirt.
 During the use of high-pressure cleaners aerosols
can develop. Inhaling aerosols can cause health
damage.
– Depending on the application, completely shielded
nozzles (e.g. surface cleaner) that significantly re-
duce the emission of aqueous aerosols can be
used for high-pressure cleaning.
– The use of such shielding is not possible with all
applications.
– If the use of a completely shielded nozzle is not
possible, a respirator of the category FFP 2 or the
like should be used, depending on the environment
to be cleaned.

Safety Devices

CAUTION
Safety installations serve the protection of the user and
may not be modified or bypassed.
Appliance switch
The appliance switch prevents unintentional operation
of the appliance.
Lock trigger gun
The lock locks the lever of the trigger gun and prevents
the accidental start of the device.
Auto-stop function
If the lever on the trigger gun is released, the pressure
switch turns off the pump, the high-pressure jet stops. If
the lever is pulled the pump is turned on again.

Symbols on the machine

The high pressure jet must not be directed at
persons, animals, live electrical equipment
or at the appliance itself.
Protect the appliance against frost.
The appliance must not be directly connect-
ed to the public drinking water network.
