cord is damaged, please arrange for it to 
be replaced immediately by an authorised 
repair agent or a skilled electrician

Check the high-pressure hose for damage 
before every use. Please arrange for the 
immediate replacement of a damaged 
high-pressure hose.

The appliance may not be used in areas 
where a risk of explosion is present.

If the appliance is used in hazardous are-
as (e.g. filling stations) the corresponding 
safety provisions must be observed.

High-pressure jets can be dangerous if 
improperly used. The jet must not be di-
rected at persons, animals, live electrical 
equipment or at the appliance itself.

The high-pressure jet must not be direct-
ed at other persons or directed by the user 
at him/herself to clean clothing or foot-
wear.

Never use the appliance to clean objects 
containing hazardous substances (e.g. 
asbestos).

Vehicle tyres or tyre valves are suscepti-
ble to damage from the high-pressure jet 
and may burst. The first indication of this 
is a discolouration of the tyre. Damaged 
vehicle tyres/tyre valves are highly dan-
gerous. Ensure that a distance of at least 
30 cm is observed when cleaning with the 
jet!

Risk of explosion!
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 thus generated is high-
ly inflammable, explosive and poisonous. 
Do not use acetone, undiluted acids and 
solvents as they are damaging to the ma-
terials from which the appliance is made.

Warning

The mains plug and the coupling of an ex-
tension cable must be watertight and must 
never lay in the water.

Unsuitable extension cables can be haz-
ardous. Only use extension cables out-
doors which have been approved for this 
purpose and labelled with a sufficient ca-

ble cross-section: 1 - 10 m: 1.5 mm

2

; 10 - 

30 m: 2.5 mm

Always fully unroll electrical cables from 
the cable drum.

High-pressure hoses, fixtures and cou-
plings are important for the safety of the 
appliance. Only use high-pressure hoses, 
fixtures and couplings recommended by 
the manufacturer.

This appliance is not intended for use by 
persons with reduced physical, sensory or 
mental capabilities. 
The appliance must not be operated by 
children or persons who have not been in-
structed accordingly.
Children should be supervised to prevent 
them from playing with the appliance.

Keep packaging film away from children - 
risk of suffocation!

The operator must use the appliance cor-
rectly. When working with the appliance, 
he must consider the local conditions and 
pay due care and attention to other per-
sons, in particular children, who are near-
by.

Do not use the appliance when there are 
other persons around unless they are also 
wearing safety equipment. 

Wear protective clothing and safety gog-
gles to protect against splash back con-
taining water or dirt.

Caution

In case of extended downtimes, switch 
the appliance off at the main switch / ap-
pliance switch or remove the mains plug.

Do not operate the appliance at tempera-
tures below 0 °C.

Observe a distance of at least 30 cm when 
using the jet to clean painted surfaces to 
avoid damaging paintwork.

Never leave the appliance unattended 
when it is in operation.

Make sure that the power cable or exten-
sion cables are not damaged by running 
over, pinching, dragging or similar. Pro-
tect the power cable from heat, oil, and 
sharp edges.

All current-conducting parts in the working 
area must be protected against jet water.
