      Safety devices

      CAUTION

      Missing or modified safety devices

      Safety devices are provided for your own protection.

      Never modify or bypass safety devices.

      Power switch

      The power switch prevents unintentional operation of the device.

      High-pressure gun lock

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

      Auto-stop function

      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.

      Motor circuit breaker

      The motor circuit breaker shuts off the device if power consumption it too high.

      Symbols on the device

      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.

      Assembly

      Fit the supplied loose parts onto the device before starting up the device.

      Mounting the transport handle

      1. Attach the transport handle.

      Installing the water connection coupling

      1. Screw the water connection coupling onto the water connection on the device.

      Initial startup

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

      2. Insert the high-pressure hose into the quick coupling until it audibly latches into place.

      3. Insert the high-pressure hose into the high-pressure gun until it audibly latches into place.

        Note

        Take care to ensure the correct alignment of the nipple.

      4. Check for a secure connection by pulling on the high-pressure hose.

      5. Plug the mains plug into a mains socket.

      Water supply

      For the connection values, see the type plate or chapter Technical data.

      Observe the water distribution company regulations.

      ATTENTION

      Damage through contaminated water

      Contamination in the water can damage the pump and the accessories.

      KÄRCHER recommends using the KÄRCHER water filter for protection(special accessory, order number 4.730-059).

      Connection to the water line

      ATTENTION

      Hose coupling with Aquastop on the water connection of the device

      Damage to the pump

      Never use a hose coupling with Aquastop on the water connection of the device.

      You can use an Aquastop coupling on the tap.

      1. Plug the garden hose onto the water connection coupling.

      2. Connect the garden hose to the water line.

      3. Open the water tap fully.

      Sucking water from open containers

      When used with the KÄRCHER suction hose with check valve (special accessory, order number 2.643-100) this high-pressure cleaner is suitable for sucking up surface water, e.g. from rain barrels or ponds (for the maximum suction height see chapter Technical data).

      The water connection coupling is not required for vacuuming operation.

      1. Fill the suction hose with water.

      2. Screw the suction hose onto the device water connection and hang it in a water source (e.g. water butt).

      Vent the device

      1. Switch the device on "I/ON".

      2. Unlock the lever of the high-pressure gun.

      3. Press the lever of the high-pressure gun.

        The device switches on.

      4. Allow the device for run a maximum of 2 minutes until the water escaping from the high-pressure gun is free of air bubbles.

      5. Release the lever of the high-pressure gun.

      6. Lock the lever of the high-pressure gun.

      Operation

      ATTENTION

      Pump running dry

      Damage to the device

      If pressure does not build up in the device after 2 minutes then switch the device off and proceed according to the instructions in chapter Troubleshooting guide.

      High-pressure operation

      ATTENTION

      Damage to painted or sensitive surfaces

      Surfaces can be damaged when the jet is too close to the surface or an unsuitable spray lance is used.

      Maintain a minimum spray distance of 30 cm when cleaning painted surfaces.

      Do not clean car tyres, paint or sensitive surfaces such as wood with the dirt blaster.

      1. Insert a spray lance into the high-pressure gun and lock it by turning it 90°.

      2. Switch the device on ("I/ON").

      3. Unlock the lever of the high-pressure gun.

      4. Press the lever of the high-pressure gun.

        The device switches on.

      Operation with detergent

      DANGER

      Failure to adhere to the safety data sheet

      Incorrect handling of the detergent can seriously damage your health

      Observe the safety data sheet of the detergent manufacturer, in particular the instructions on personal protective equipment.

      Note

      Detergent can only be mixed into the jet at low pressure.

      Note

      KÄRCHER detergents ensure fault-free operation. Ask us for a consultation, request our catalogue or our detergent information sheets.

      1. Pull the desired length of the detergent suction hose out of the casing.

      2. Hang the detergent suction hose in a container with detergent solution.

      3. Use the Click-Vario Power spray lance.

      4. Turn the spray lance to "MIX".

        The detergent solution is mixed with the water jet during operation.

      Recommended cleaning method

      1. Spray the detergent sparingly on the dry surface and let it work for a while (do not let it dry).

      2. Rinse off the loosened dirt with the high-pressure jet.

      After operation with detergent

      1. Flush the device with clear water for approx. 30 seconds.

      Interrupting operation

      1. Release the lever of the high-pressure gun.

        The device switches off when the lever is released. The high pressure in the system is retained.

      2. Lock the lever of the high-pressure gun.
