Safety instructions
Read this safety chapter and these original 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 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.
Operation
DANGER
Operation in explosive atmospheres is prohibited.
DANGER
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.
DANGER
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.
WARNING
Do not aim the high-pressure jet at yourself, e.g. to clean clothes or shoes.
WARNING
Do not direct the high-pressure jet at persons, animals, live electrical equipment or at the device itself.
WARNING
Do not spray any objects which contain harmful substances (e.g. asbestos).
WARNING
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.
WARNING
Only use high-pressure hoses, control panels and couplings specified by the manufacturer.
WARNING
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.
CAUTION
Water that has flowed through a system separator is no longer classified as drinkable.
CAUTION
Never leave the device unsupervised while it is in operation.
CAUTION
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.
CAUTION
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.
Protective gear
CAUTION
Wear suitable protective clothing and safety goggles to protect yourself from water or dirt backsplash.
CAUTION
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. 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.
Risk of electric shock
DANGER
Only connect protection class I devices to properly earthed power sources.
DANGER
Only connect the device to alternating current. The voltage indicated on the type plate must match the voltage of the power source.
DANGER
Only operate the device via a fault current protection switch (maximum 30 mA).
DANGER
Never touch the mains plug and socket with wet hands.
DANGER
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.
DANGER
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.
WARNING
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.
WARNING
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.
WARNING
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.
CAUTION
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
WARNING
Incorrect use of detergents can cause serious injuries or poisoning.
CAUTION
Keep the detergent out of the reach of children.
CAUTION
Only use the detergents supplied or specified by the manufacturer. The use of other detergents 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.
