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.

ATTENTION •Switch-on procedures will generate short-term voltage drops. •Unfavourable mains conditions may cause other devices to be impaired. •In case of a network impedance of less than 0.15 ohms, no malfunctions are to be expected.

Water connection

WARNING The device must not be started up if the high-pressure hose is damaged. Replace a damaged high-pressure hose at once. Only those hoses and connections recommended by the manufacturer may be used. For order no. see operating instructions. The screw connections of all connection hoses must be leak-tight.

ATTENTION Observe the regulations at your water distribution company.

Operation

DANGER · When using the device in hazard zones (e.g. service stations), adhere to the respective safety regulations.

• 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. With short spray lances, your hand may come into contact with the high-pressure jet. Never use a spotlight nozzle or rotary nozzle with steel tubes that are shorter than 75~cm . A recoil force will arise due to the water stream ejecting from the spray lance. An angular spray lance produces a force that acts in upward direction. Make sure you grip the gun and spray lance firmly. When using angular spray units, recoil forces and twisting forces may alter. 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.

CAUTION Never leave the device unsupervised while it is in operation. Never open the cover while the motor is running.

• Never clamp the lever of the high-pressure gun during operation. -Allow the hoses to cool down after hot water operation or operate the device briefly using cold water operation. -The device must be placed on an even, firm subsurface. -Before cleaning, carry out a risk assessment of the surface to be cleaned to determine any health and safety protection requirements. The necessary protective measures must be taken accordingly.

ATTENTION Do not operate the device at temperatures below 0^ . Only clean the motor at washing stations with an oil separator.

Operation with detergent

CAUTION Keep the detergent out of the reach of children. When using detergents, observe the safety data sheet of the detergent manufacturer, in particular instructions on protective gear. Only use the detergents supplied or specified by the manufacturer. The use of other detergents or chemicals can impair the safety of the device. Never use the recommended detergents undiluted.

These products are operationally safe since they do not contain any acids, alkali or substances that are harmful to the environment. Should detergents come into contact with eyes, rinse these out immediately and thoroughly using water and seek medical attention immediately. The same applies if detergents are swallowed.

Device with a hand-arm vibration value >2.5 ~m / s^2 (see chapter Technical Data in the operating instructions)

△CAUTION

Using the device for longer periods can cause poor circulation in the hands due to vibrations. A general period of use cannot be set, because this depends on several influencing factors:

• Personal tendency to suffer from poor circulation (frequently cold fingers, tingling sensation in the fingers)
• Low ambient temperature. Wear warm gloves to protect your hands.
• Holding the device too tightly hindering blood circulation.
• Continuous operation is more harmful than operation interrupted by work breaks.

You should see a doctor if using the device regularly and for lengthy periods of time, and in the event of repeated occurrenc

es of symptoms such as tingling in the fingers or cold fingers.
