Operating Instructions

Please read the operating instructions carefully before using the unit.

Safety instructions

Please read and comply with these original in- structions prior to the initial operation of your appliance and store them for later use or subsequent owners. Apart from the notes contained herein the general safety provi- sions and rules for the preven- tion of accidents of the legislator must be observed. Warnings and notes that are attached on the appliance provide important notes for the safe operation.

Hazard levels

DANGER
Pointer to immediate danger, which leads to severe injuries or death.
WARNING
Pointer to a possibly dangerous situation, which can lead to severe injuries or death.
CAUTION
Pointer to a possibly dangerous situation, which can lead to minor injuries.
ATTENTION
Pointer to a possibly dangerous situation, which can lead to property damage.
Electric components

DANGER
Risk of electric shock.

Never touch the mains plug and the socket with wet hands.
Check the power cord with mains plug for damage prior to every use. Immediately have damaged power cord replaced by an authorised customer service / electrician. Do not operate an appliance if the power cord is damaged.
All current-conducting parts in the working area must be protected against jet water.
The mains plug and the coupling of an extension cable must be watertight and must never lie in water. Moreover, the coupling may never lie on the ground. The use of cable reels that ensure that the sockets are at least 60 mm above the ground is recom- mended.
Make sure that the power cord or extension cable is not damaged by running over, pinching, dragging or the like. Protect the power cords from heat, oil, and sharp edges.
Turn off the appliance and remove the mains plug prior to any care and maintenance works.
Repair work and work on the electrical components may only be performed by an authorised customer service.
WARNING
The appliance may only be connected to an electric supply that has been installed by an electrician in accordance with IEC 60364.
The appliance may only be connected to alternating current. The voltage must correspond with the type plate of the appliance.
Safety class I – Appliances may only be connected to sockets with proper earthing.
For safety reasons, we recommend that you operate the appliance only via a residual current device (max. 30 mA).
An unsuitable electrical extension cable can be hazardous. Only use an electrical extension cable which has been approved and labelled for this purpose and has an adequate cable cross-section outdoors: 1 – 10 m: 1.5 mm² ; 10 – 30 m: 2.5 mm²
Always fully unreel the extension cable from the cable drum.

Safe handling

DANGER

The user must use the appliance as intended. The person must consider the local conditions and must pay attention to other persons in the vicinity when working with the appliance.
Check important components, such as high-pressure hose, hand spray gun and safety installations, for damage prior to every operation. Immediately replace damaged components. Do not operate appliance with damaged components.
High-pressure jets can be dangerous if improperly used. The jet may not be directed at persons, animals, live electrical equipment or at the appli- ance itself.
The high-pressure jet must not be directed at other persons or the user him-/herself to clean clothing or footwear.
Vehicle tyres/tyre valves are susceptible to damage from the high-pressure jet and may burst. The first indication for this is a discolouration of the tyre. Damaged vehicle tyres/ tyre valves are perilous. Keep a minimum jet distance of 30 cm during cleaning! WARNING
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, sensory or mental capacities or lacking experience and/or skills, unless such persons 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 appliance.
Supervise children to prevent them from playing with the appliance.
CAUTION
Create stability for the appli- ance 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 the appliance off at the main switch / appliance switch or pull the mains plug.
Do not operate the appliance at temperatures below 0 °C.

Other risks

DANGER

The appliance may not be operated in explosive atmospheres.
Never use the appliance to clean objects containing hazardous substances (e.g. asbestos).
Do not spray flammable liquids.
Never draw in fluids containing solvents or undiluted acids and solvents! This includes petrol, paint thinner and heating oil. The spray mist is highly inflammable, explosive and poisonous. Do not use acetone, undiluted acids and solvents, as they corrode the materials used on the appliance.
Keep packaging films away from children, there is a risk of suffocation!
WARNING
According to applicable regu- lations, 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 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 recommended by the manufacturer.
When disconnecting the supply or high pressure hose, hot water may leak from the connections after operation.
CAUTION
Mind the weight of the appliance when selecting the storage location and during transport (see technical data) to prevent accidents or injuries.
Several hours of continuous use of the appliance can lead to numbness in the hands in rare cases.
Wear gloves.
Keep hands warm.
Take breaks at regular intervals.

Working with detergent
WARNING

This appliance was designed to be used with detergents which are supplied or recommended by the manufacturer. The use of other detergents or chemicals may compromise the safety of the appliance.
The improper use of detergents can cause severe injuries or toxication.
Store detergents away from the reach of children.

Safety Devices

CAUTION

Safety installations serve the protection of the user and may not be modified or bypassed.

Power switch
The appliance switch prevents unintentional operation of the appliance.
Lock trigger gun
This lock locks the lever of the trigger gun and prevents the inadvertent start of the appliance.
Overflow valve with pressure switch
If the lever on the trigger gun is released the pressure switch turns off the pump, the high pressure jet is stopped. If the lever is pulled the pump is turned on again.
Motor protection switch
The motor protection switch switches off the device if the power consumption is high.

Symbols on the machine
The high pressure jet must not be directed at persons, animals, live electrical equipment or at the appliance itself.
Gerät vor Frost schützen.
The appliance must not be directly connected to the public drinking waternetwork.

Personal protective equipment

CAUTION

Wear protective clothing and safety goggles to protect 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 applica- tion, completely shielded nozzles (e.g. surface cleaner) that significantly reduce the emission of aqueous aerosols can be used for highpressure 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.
