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

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

  • 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.

Protective gear

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 significantly 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.

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

  • 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.
    • Children must not operate the device
    •  Children must be supervised to prevent them from playing with the appliance.
  • CAUTION

    • Safety devices are provided for your own protection. Never modify or bypass safety devices.
Risk of electric shock
  • 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.
  • WARNING
    • Only connect the device to an electrical connection which has been set up by a qualified 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 possible danger, a damaged mains connection cable must be immediately replaced by the manufacturer, or the authorised 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 cables are dangerous. Only use approved and appropriately marked electrical extension cables with a sufficient line cross section when outdoors: 1-10 m : 1.5 mm2, 10-30 m : 2.5 mm2
  • 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
  • DANGER
    •  Operation in explosive atmospheres 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 discoloration of the tyres. Keep a spray distance of at least 30 cm when cleaning the wheels / tyre valves.
  • 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 after operation.
  • CAUTION
    • According to the applicable regulations, the appliance may never be used with the drinking 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 operation.
    •  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 temperatures below 0 °C.
Operation with detergent
  • WARNING
    • Incorrect use of detergents can cause serious injuries or poisoning.
  • 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.
Care and service
  • WARNING
    • Always pull out the mains plug before all care and maintenance work.
  • CAUTION
    • Have repair work and work on electrical components carried out by the authorised customer service only.
  • ATTENTION
    • Do not use acetone, undiluted ac-ids or solvents, as they corrode the materials used on
      the device.
Transportation
  • CAUTION

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