Safety instructions

Read this safety chapter and these origi- nal instructions before using the device for the first time. Act in accordance with

them. Keep the original instructions for future reference or for future owners.

• In addition to the notes in the operating instructions, you also need to take into consideration the general safety regulations and accident prevention guide- lines applicable by law.
• Warnings and information notices attached to the device provide important information for hazard-free

 Hazard levels

F DANGER

• Indication of an imminent threat of danger that will lead to severe injuries or even death.

W WARNING

• Indication of a potentially dangerous situation that may lead to severe injuries or even death.

W CAUTION

• Indication of a potentially dangerous situation that may lead to minor injuries.

ATTENTION

• Indication of a potentially dangerous situation that may lead to damage to property.

Operation F DANGER ● Operation in explosive atmos- pheres is prohibited. ● Never suction solvents, liquids

containing solvents or undiluted acids. This includes

e.g. petrol, paint thinner or heating oil. The spray mist is highly flammable, explosive and poisonous. ● Dam- aged wheels / tyre valves are extremely dangerous. Damaged wheels / tyre valves can be damaged by the high- pressure jet and explode. The first sign of this is discolouration of the tyres. Keep a spray distance of at least 30 cm when cleaning the wheels / tyre valves.

W WARNING ● Do not use the device if people without the proper protective clothing are in its reach.

• Do not aim the high-pressure jet at yourself, e.g. to clean clothes or shoes. Do not direct the high-pres- sure jet at persons, animals, live electrical equipment or at the device itself. ● Do not spray any objects which contain harmful substances (e.g. asbestos). ● Check the device and the accessories, such as the high-pres- sure hose, high-pressure gun and safety devices, to make sure they are in proper safe and reliable condition before each operation. Do not use the device if it is dam- aged. Replace damaged components immediately.
• Only use high-pressure hoses, control panels and couplings specified by the manufacturer. Risk of scalding. When disconnecting the supply or high-pres- sure hose, hot water can leak out of the connections af- ter operation.

W CAUTION ● According to the applicable regu- lations, the appliance may never be used with the drink- ing water network without a system separator. Ensure that the connection to your house water system, with which the high-pressure cleaner is operated, is equipped with a system separator according to

EN 12729 type BA. ● Water that has flowed through a system separator is no longer classified as drinkable.

• Never leave the device unsupervised while it is in op- ● Recoil force from the water stream emerging at the high-pressure nozzle acts on the high-pressure gun. Keep proper footing and hold the high-pressure gun and spray lance firmly. ● Accidents or damage due to the device falling over. Before all actions with or on the device, you must make sure that it is stable. ATTENTION ● Do not operate the device at tem- peratures below 0 °C.

** W CAUTION ● Wear suitable protective clothing and safety goggles to protect yourself from water or dirt _backsplash. ●**_ Aerosols can be formed when using high-
pressure cleaners. Inhaling aerosols can be harmful for your health. Depending on the application, the use of fully shielded nozzles (e.g. surface cleaners) can signif- icantly lower the emission of aqueous aerosols. De- pending on the environment to be cleaned, wear a suitable respiratory protective mask of class FFP 2 or comparable to protect yourself from inhaling aerosols if the use of a fully shielded nozzle is not possible.

Risk of electric shock F DANGER ● Only connect protection class I de- vices to properly earthed power sources. ● Only con- nect the device to alternating current. The voltage
indicated on the type plate must match the voltage of the power source. ● Only operate the device via a fault current protection switch (maximum 30 mA). ● Never touch the mains plug and socket with wet hands. ● The mains plug and coupling of the extension cable must be water tight and may not be placed in water. The coupling may not be on the floor. Use cable drums to ensure that the sockets are at least 60 mm above the floor. ● All live parts in the work area must be protected against water jets.

W WARNING ● Only connect the device to an electrical connection which has been set up by a quali- fied electrician as per IEC 60364-1. ● Check that the mains connection cable with mains plug is undamaged each time before using the device. To avoid any possi- ble danger, a damaged mains connection cable must be immediately replaced by the manufacturer, or the au- thorised customer service department or a qualified electrician. ● Do not damage the power supply and ex- tension cable by running over it, crushing or yanking it or similar. Protect the power supply cable from heat, oil and sharp edges. ● Unsuitable electrical extension ca- bles are dangerous. Only use approved and appropri- ately marked electrical extension cables with a sufficient line cross section when outdoors: 1-10 m : 1.5 mm2, 10-30 m : 2.5 mm2

W CAUTION ● Always fully unwind the extension cable from the cable drum. ● In case of longer breaks in operation and after use, switch off the device at the main switch / device switch and pull the mains plug.

Operation with detergent W WARNING ● Incorrect use of detergents can cause serious injuries or poisoning.
W CAUTION ● _Keep the detergent out of the reach of children. ● Only use the detergents supplied or specified by the manufacturer. The use of other deter- gents or chemicals can impair the safety of the device.
_W WARNING ● Always pull out the mains plug before all care and maintenance work.
W CAUTION ● Have repair work and work on electrical components carried out by the authorised cus- tomer service only.
ATTENTION ● Do not use acetone, undiluted ac- ids or solvents, as they corrode the materials used on the device.

Transportation

W CAUTION

• Risk of accidents and Take into account the weight of the device for transportation and storage. See chapter Technical data in the operating instruc- tions.

General safety instructions F DANGER ● Risk of asphyxiation. Keep pack- aging film out of the reach of children.

W WARNING ● Only use the device for its proper use. Take into account the local conditions and beware of third parties, in particular children, when working with the device. ● Persons with reduced physical, sensory or mental capabilities and persons lacking experience and knowledge may only use the appliance if they are properly supervised, have been instructed on use of the appliance safely by a person responsible for their safety, and understand the resultant hazards involved. ● Chil- dren must not operate the device. ● Children must be supervised to prevent them from playing with the appli- ance.

W CAUTION ● Safety devices are provided for your own protection. Never modify or bypass safety de- vices.
