Safety instructions

Read these safety instructions and the original instructions before using the device for  the first time. Act in accordance with them. Keep the two booklets 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 guidelines 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.

Personal protective equipment
CAUTION

• Wear suitable protective clothing and safety goggles to protect yourself from water or dirt backsplash.
•  Aerosols can be formed when using highpressure 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. Depending 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 warnings

• 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, or those with a lack of experience and knowledge, are only allowed to use the appliance if they are supervised or have been instructed with re- spect to using the appliance safely, and understand the resultant dangers 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 devices to properly earthed power sources.

• Only connect the device to  alternating current. The voltage indicated on the type plate must match the voltage ofthe 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 bewater tight and may not be placed in water. The coupling may not be on the floor. Use cable drums to ensure thatthe 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 the power supply cable with mains plug for damage before operation each time. Do not put the device into operation with a damaged power supply cable. Have a damaged power supply cable replaced immediately by the authorised customer service / qualified electrician.
•  Do not damage the power supply and extension 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 mm 2 2 , 10-30 m : 2.5 mm

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.
• Damaged 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.

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-pressure 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-pressure 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 damaged. 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-pressure 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.
