Installation

Note
The handle is installed only once. The handle halves may not be separated again after installation. Take care to ensure that the water hose and the mains cable are not crushed during installation.

2. Press the water hose and then the mains cable into the cable channel from the top to the bottom (starting at the hand grip).
   
3. Press any protruding cable and water hose firmly into the brush head casing.
   

The mains cable and water hose must not protrude out of the device during operation!

Initial startup

1. Close the water volume regulation valve.
   
2. Connect the water hose to the device. The coupling must audibly engage.
3. Secure the water hose to the hand grip using hook and loop fastener to provide strain relief.
   
4. Connect the water hose to the water tap and open the water tap. Please observe the maximum water pressure (see "Technical data").
5. Connect the mains cable to a suitable extension cable labelled as conforming to protection class IPX4. Please be sure to observe the safety instructions.

Operation

Correct handling of the brushes

Note
Use only the brushes suitable for the surface to be cleaned and the device.
Observe the following instructions for correct use of the brushes.

1. Position the brushes evenly on the surface to be cleaned.
   
2. Guide the brushes over the surface with light pressure.

Switching on the device

1. Press the unlocking button.
   
2. Press the power switch. The device starts up.
3. Release the power switch.
   The device stops.

Water volume regulation valve

Note
The volume of water emitted by the device through the nozzles can be adjusted using the water volume regulation valve to suit the cleaning task.

1. Pull the valve lever backwards to increase the water volume.
2. Push the valve lever forwards to decrease the water volume or close the valve completely.
   See Illustration H

Cleaning wooden surfaces

Use the brushes for wooden floor coatings for cleaning wooden surfaces.

Note

• Test the device on an inconspicuous area before using on sensitive surfaces.
• Do not allow the device to remain in one area, keep it in motion.

Note

• Always clean wooden surfaces in the direction of the grain. Always clean along the floorboards or wooden elements and down the slope.

Note
Pre-treatments may be removed from pre-treated surfaces. Uneven light-dark effects result from the type of wood or its treatment. It is a desirable result to remove the film on weathered wooden surfaces.

1. Guide the device slowly over the surface.
   

For optimum results, apply a suitable care agent or preservative after cleaning!

Cleaning stone surfaces

Use the brush for stone coverings for cleaning stone surfaces in outside areas (not included in the scope of delivery - see the Accessories and spare parts chapter for sources).

Note
Remove any loose elements such as gravel before cleaning.

1. Guide the device slowly over the surface.

Storing the device

The device can be stored hanging on a wall hook. You can also alternatively place the device on the parking edge of the spray guard. Take care to ensure that the device does not stand on the brushes to prevent damage to the bristles.

1. Disconnect the connections.
2. Empty the device (see "Frost protection").
3. Clean the device (see "Cleaning").

Troubleshooting guide

Malfunctions often have simple causes that you can remedy yourself using the following overview. When in doubt, or in the case of malfunctions not mentioned here, please contact your authorised Customer Service.

Device does not run or switches off during operation

No voltage supply

• Check the voltage supply (plug connections of the extension cable).

The fault current protection switch has triggered

• Check the in-house fault current protection switch. Consult a qualified electrician if the fault occurs frequently.

The motor overload switch has triggered

• Allow the device to cool down (at least 10 minutes). The motor overload switch resets automatically and the device is ready for operation again.
  The power switch must not be pressed during the cooling phase to avoid the device starting up unexpectedly. Always wait for the specified cooling time before restarting the device. In case of a repeated shut-down, reduce the pressure on the brushes while cleaning and hold the device at a flatter angle.
