Initial startup 몇 WARNING Damaged components Risk of injury Check that the device, accessories, supply lines and connections are in perfect condition. If the condition is not perfect, you may not use the device.

1. Apply the parking brake.

Check the oil level in the high-pressure pump ATTENTION Milky oil Device damage If the oil is milky, inform authorized Customer Service immediately.

1. Place the device on a flat and level surface.

2. Check the high-pressure pump oil level at the oil lev-

el display. The oil level must be in the middle of the oil level in- dication.

3. Top up the oil if necessary.

Activating the oil tank venting

1. Unscrew the screw plug.

2. Screw in the oil filler plug.

Do not aim the high-pressure jet may at persons, animals, live electrical equip- ment or the device itself. Protect the device against frost. Danger of injury from electrical voltage. Only qualified electricians or authorised and qualified technical specialists are permitted to work on the electrical sys- tems. Health risk from poisonous exhaust gases. Never inhale the exhaust gases. Risk of burns from hot surfaces.14 English Installing accessories

1. Connect the spray lance to the high-pressure gun

2. Plug the high-pressure nozzle onto the spray lance.

3. Mount the union nut and hand-tighten.

4. Connect the high-pressure hose to the high-pres-

sure gun and high-pressure connection of the de- vice and tighten hand-tight. Refuelling DANGER Unsuitable fuel Risk of explosion Only use diesel fuel or light heating oil. Unsuitable fuels, such as petrol, must not be used. ATTENTION Operation with an empty fuel tank Destruction of the fuel pump Never operate the device with an empty fuel tank.

Water connection 몇 WARNING Danger of backflow of contaminated water into the drinking water network Health risk Observe the regulations of your water supply company. According to applicable regulations, the device must never be used with the drinking water network without a system separator. Use a system separator from KÄRCHER or a system separator as per EN 12729 Type BA. Water that has flowed through a system sep- arator is classified as undrinkable. Always connect the system separator to the water supply and never directly to the water connection on the device. ● See the "Technical data" for the connected loads. Note The supply hose is not included in the scope of delivery. Note The system separator is not included in the scope of de- livery.

1. Connect the system separator to the water inlet (e.g.

2. Connect the inlet hose (minimum length 7.5 m, min-

imum diameter 1”) to the water connection of the de- vice and to the system separator.

3. Open the water inlet.

Suck water from the container DANGER Suction of fluids containing solvents or drinking water Risk of injury and damage, contamination of drinking water Never extract fluids containing solvents such as paint thinner, petrol, oil or unfiltered water. The seals in the device are not resistant to solvents. The spray mist of solvents is highly flammable, explosive and poisonous. Never extract water from drinking water tanks.

1. Connect the suction hose (diameter at least 1”) to

the water connection.

2. Hang the suction hose in an external water source.

Note Maximum suction height: 0.5 m Electrical connection DANGER Unsuitable electrical extension cables Electric shock Only use approved and appropriately marked electrical extension cables with a sufficient line cross section for outdoors. Make sure that the plug and coupling of an extension cable used are watertight. Always unroll extension cables completely. ATTENTION Exceeding the grid impedance Electrical shock in the event of a short-circuit The maximum permissible mains grid impedance at the electrical connection point (see Technical data) must not be exceeded. Contact your electricity supplier in the case of any un- certainties regarding the mains grid impedance at your electrical connection point. ● For connected loads, see technical data and type plate. ● The electrical connection must be carried out by an electrician and comply with IEC 60364-1. Operation DANGER Flammable fluids Risk of explosion Do not spray inflammable liquids. DANGER Operation without spray lance Risk of injury Never operate the device without the spray lance in- stalled. Before each use, check that the spray lance is firmly seated. The screw connection of the spray lance must be tightened hand tight. DANGER High-pressure water stream Risk of injury Never fasten the trigger in the actuated position. Before doing any work on the device, secure the high- pressure gun by folding out the safety lever and engag- ing it. Hold the high-pressure gun and spray lance with both hands. ATTENTION Operation with an empty fuel tank Destruction of the fuel pump Never operate the device with an empty fuel tank. Changing nozzles
