      Low-maintenance batteries (wet batteries)

        DANGER

        Danger of burns due to acid leakage!

        Only fill the battery with water when it is discharged.

        When handling battery acid, use safety goggles and immediately rinse out any acid splashes on the skin or clothing with water.

        ATTENTION

        Risk of damage to the batteries!

        Using water with additives will void the battery's warranty.

        Top up the batteries using only distilled or desalinated water (EN 50272-T3).

        Do not use any foreign additives or touch-up agents.

      1. Add distilled water one hour before the charging process comes to an end. Observe the correct acid level according to the battery label.

        All cells must produce gas at the end of the charging process.

      Maintenance-free batteries (AGM and gel batteries)

        ATTENTION

        Risk of damage from AGM and gel batteries!

        Opening or drilling the battery housing will damage an AGM or gel battery. It must then be replaced.

        Do not open the battery housing and do not drill any holes.

        Do not cover the pressure relief valve and do not change it.

      1. Only charge AGM and gel batteries using the specified chargers, see chapter: Charging the battery.

      Adjusting the water volume

      1. Adjust the water volume via the regulating knob to suit the degree of soiling of the floor covering.

        Note

        Perform initial cleaning tests with a low water volume. Increase the water volume step by step until achieving the desired cleaning result.

        Note

        The cleaning head continues operating without a liquid supply if the fresh water tank is empty.

      Adjusting the suction bar

      Adjusting the inclination

      The inclination must be adjusted so that the suction lips of the suction bar make even contact with the floor over the entire length of the suction bar.

      1. Loosen the screw.


        1. Screw
      2. Adjust the inclination of the suction bar.

      3. Tighten the screw.

      Adjusting the height

      The height adjustment affects the bending of the suction lips on contact with the floor.

      1. Push the device a small distance forwards.

      2. Compare the bending of the suction lips with the figure below.


        1. Spacer roller with holder
        2. Washer
        3. Screw
      3. Unscrew the screw.

      4. Insert a sufficient number of washers between the suction bar and spacer roller to create the correct bending of the suction lip.

      5. Fit the remaining unused washers above the spacer roller.

      6. Screw in and tighten the screw.

      7. Repeat the entire procedure at the second spacer roller.

      8. Push the device a small distance forwards.

      9. Check the bending of the suction lips over the entire length.

      10. Repeat the adjustment procedure if necessary.

      Cleaning

      Switching on the device

      1. Turn the key-operated switch to "1".

        The display shows the following one after the other:

        • Period of time until the next after-sales Customer Service

        • Charging state of the battery and number of operating hours

      Cleaning

      Note

      The inclination and height of the suction bar can be adjusted to improve the vacuuming results (see chapter Adjusting the suction bar).

      Note

      When the waste water tank is full, the float switch closes the suction opening and the suction turbine runs at a higher speed. In this case, raise the suction bar and drive to the location for emptying the waste water tank.

      1. Turn the working speed rotary knob to the desired value.

        The speed is shown on the display during the adjustment. The display is shown in percentage of the maximum speed.

      2. Set the water volume at the regulating valve.

      3. Press the suction bar lever downwards.

        The suction bar lowers.

        Vacuuming begins.
