Warnings and information notices attached to the device provide important information for hazard-free operation.

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.

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.

DANGER

Risk of asphyxiation. Keep packaging 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.

WARNING

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.

WARNING

Children must not operate the device.

WARNING

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.

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.

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.

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.

The power switch prevents unintentional operation of the device.

The lock locks the lever of the high-pressure gun and prevents the device from starting unintentionally.

If the lever of the high-pressure gun is released, the pressure switch turns off the pump and the high-pressure jet stops. The pump switches on again when the lever is pressed.

The device shuts off automatically after 2 minutes of dry running so as to prevent damage to the high-pressure pump.

	Do not aim the high-pressure jet may at persons, animals, live electrical equipment or the device itself. Protect the device against frost.
	The device may not be connected to the public drinking water network.

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Electrical and electronic devices contain valuable, recyclable materials and often components such as batteries, rechargeable batteries or oil, which - if handled or disposed of incorrectly - can pose a potential danger to human health and the environment. However, these components are required for the correct operation of the device. Devices marked by this symbol are not allowed to be disposed of together with the household rubbish.

Cleaning work producing in oily waste water, e.g. washing engines, washing undercarriages etc., may only be performed at washing stations with an oil separator.

Working with detergents may only be performed on watertight surfaces with connection to the waste water sewage system. Do not allow detergent to enter waterways or the soil.

Extraction of water from public waterways is not permitted in some countries.
