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 to 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 instructions

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.
Persons with reduced physical, sensory or mental capabilities and persons lacking experience and knowledge may only use the appliance if they are properly supervised, ave 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. ever modify or bypass safety devices.

Risk of electric shock

DANGER

Only connect protection class I devises to properly earthed power sources.
Only connect 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 main 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 that has been set up by a qualified electrician as per IEC 60364-1.
Check that the mains connection cable with the 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 authorized customer service department, or a 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/tire valves are extremely dangerous. Damaged wheels/tire valves can be damaged by the high-pressure jet and explode. The first sign of this is the discoloration of the tires. Keep a spray distance of at least 30 cm when cleaning the wheels/tire 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 the 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 detergents or chemicals can impair the safety of the device.

Care and service

WARNING

Always pull out the main plug before all care and maintenance work.

CAUTION

Have repair work and work on electrical components carried out by the authorized customer service only.

ATTENTION

Do not use acetone, undiluted acids, 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.

Environmental protection

The packing materials can be recycled. Please dispose of the packaging in accordance with the en-vironmental regulations.
Electrical and electronic appliances 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 appliance. Appliances marked by this symbol are not allowed to be disposed of together with the household rubbish.
Cleaning work producing in oily wastewater, e.g. washing engines, washing undercarriage, 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 wastewater sewage system. Do not allow detergent to enter waterways or the soil.
Extraction of water from public waterways is not -21- permitted in some countries. Notes on the content materials (REACH) Current information on content materials can be found at: www.kaercherde/REACH
