) ........................................≤2.5 m/s2 The values for noise and vibration were deter- mined according to EN 60335-2-79:2012. The vibration emission value has been measured according to a standardised testing method and may be used for comparison with another pow- er tool. The indicated vibration emission value may also be used for an introductory assessment of the ex- posure. ⚠ WARNING! The vibration emission value whilst actually using the power tool may vary from the given values depending on the type and way in which the power tool is used. Try to keep the exposure to vibrations as low as possible. Examples of measures to reduce vibra- tion exposure are the wearing of gloves when using the tool and limiting the working hours. All parts of the operating cycle have to be consid- ered while doing so (for example, times when the – Quick connector with filter insert – Nozzle cleaning needle – Instruction manual Description of functions The pressure washer cleans using a water jet.

Symbols on the cleaning agent bottle Caution! Corrosive! Irritant! May cause serious skin burns and eye damage. Correct handling of the device General information

• Read the instruction manual care- fully. Familiarise yourself with the controls and how to use the de- vice correctly.
• The device must not be used by children. Children should be su- pervised to ensure that they do not play with the device.
• The device can be used by indi- viduals with reduced physical, sensory or mental abilities or a lack of experience and knowl- edge if they are supervised or have been instructed in the safe use of the device and understand the resulting hazards.
• People who are not familiar with the instruction manual may not use the device.
• Pressure washers must not be op- erated by untrained persons.
• In the case of a malfunction or defect during operation, the de- vice must be switched off imme- diately and the mains plug un- plugged. For possible causes of a malfunction, see Troubleshoot- ing, p.28. Or, contact our ser- vice centre.22

• Note that the user is responsible for any accidents or risks to oth- ers and their property.

• Observe noise protection rules and other local regulations. Initial start-up

• When using the device, always wear protective goggles.

• When using the device, always wear sturdy shoes and full-length trousers. Do not use the device barefoot or in light sandals.

• Do not work with a damaged or incomplete device or one which has been converted without the permission of the manufacturer. Before commissioning, have a specialist check that the required electrical protective measures are in place.

• The device may only be connect- ed to a socket that was installed by an experienced electrician in accordance with IEC60364-1.

• Prior to use, always check the connecting cable and extension cable for signs of damage or wear and tear. If the cable gets damaged during use, it must be disconnected from the supply network immediately. DO NOT

FROM THE POWER SUPPLY. Do not use the device if the cable is damaged or worn. To avoid haz- ards, a damaged mains connec- tion cable may only be replaced by the manufacturer, their custom- er service or a similarly qualified person.

• Only connect the device to a power socket with a residual cur- rent device (RCD) with a rated residual current no more than 30mA.

• Unsuitable extension cables can be dangerous! Use only exten- sion cables that are designed for outdoor use. The connection must be dry and routed above the ground. We recommend us- ing a cable drum that holds the socket at least 60mm above the ground.

• Extension cables must have a minimum wire cross section of 2 × 2.5 mm².

• High-pressure hoses, fittings and couplings are important for de- vice safety. Only use high-pres- sure hoses, fittings and couplings recommended by the manufac- turer.

• Do not start the device up if the mains connection cable, water supply or other important parts such as the high-pressure hose or spray gun are damaged or leaky.

• Only use the device standing and on a firm, level surface.23

• Switch off the device and dis- connect the mains plug from the socket. Make sure that all mov- ing parts have come to a com- plete stop:

• when leaving the device,

• before changing the accesso- ries,

• before removing obstructions or loosening blockages,

• before checking the device, cleaning it or performing main- tenance work on it.

• If the device starts to vibrate ab- normally strong, an immediate in- spection is required:

• search for signs of damage,

• replace damaged parts,

• contact the service centre. Cleaning, maintenance and storage

• Allow the motor to cool down before storing the device for a longer period.

• Replace worn or damaged parts in the interests of safety. Use only original spare parts and acces- sories.

• The device may only be opened by an authorised electrician. Al- ways contact our service centre for repairs.

• Switch the drive off, disconnect the device from the power supply and allow the device to cool off if you want to clean, adjust, store

• Never use the device if there are children or animals nearby. Peo- ple nearby must wear protective clothing. Operation

• Pay attention! Be aware of what you are doing and take the ut- most care when working with a power tool. Do not use power tools if you are tired or you are under the influence of drugs, al- cohol or medication.

• High-pressure jets can be dan- gerous if used incorrectly. The jet must not be directed at persons, animals, active electrical equip- ment or the device itself.

• Do not direct the jet at yourself or others to clean clothing or shoes.

• If you come into contact with cleaning agents, rinse them with sufficient clean water.

• Never use the mains connection cable to pull the plug out of the socket or to pull the device. Pro- tect the mains connection cable from heat, oil and sharp edges.

• Risk of explosion – do not spray any flammable liquids.

• Do not use the device near flam- mable liquids or gases. There is a risk of fire or explosion if this ad- vice is not heeded.

• Never transport the device while the drive is running.24

the device or to exchange an ac- cessory part.

• Handle the device with care and keep it clean.

• Store the device out of reach of children. Preparation ⚠ WARNING! Risk of injury due to unintention- al start-up. Do not insert the plug into the socket until the device is fully prepared for use. According to current regulations, the pressure washer must never be connect- ed to the drinking water network with- out a system separator. A suitable system separator must be used in accordance with EN12729 Type BA. Water that has flowed through a system separa- tor is classified as non-potable. System separators are available from specialist dealers. A system separator (check valve) prevents the backflow of water and cleaning agent into the drinking water pipeline. – Use a standard garden hose for the water supply and make sure it is long enough. – Use the device on a domestic water connec- tion with an output of at least 450 l/h.
