forward movement. When the mechanical drive lever is released, the brush motor
shuts down and the machine stops.
If the machine pulls to one side, restore a straight course by using the direction
regulation knob (fig. 5, ref. 10). If the machine pulls to the right, turn the knob clockwise
and vice versa.
• Models with electric drive: to move forwards or backwards, see paragraph 6.3.
periodically check that the detergent is reaching the brushes and refill when it runs out.
When there is no longer sufficient water in the detergent tank, the level indicator lights up
(fig. 5, ref. 5). Stop and fill the tank; when working, check cleaning quality and if necessary
adjust the flow of detergent by pressing the button (fig. 5, ref. 18); the amount of liquid
delivered is indicated by the LEDs (fig. 5, ref. 20).
Empty the dirty water tank each time you fill the detergent tank.
Never leave the suction motor on and detergent tap open when parked.
• when the dirty water drum is full, the level indicator comes on (fig. 5, ref. 4) and after a
few seconds the suction motor shuts off. You must stop working and empty the tank.
• if the warning LED (fig. 5, ref. 1) starts flashing, it means that the batteries are almost
flat. After a few seconds the brushes shut down to prevent excessive discharge of the
batteries. Charge the batteries.
At the end of work:
• release the brush/drive lever (fig. 5, ref. 7) located under the handgrip. This turns the
brush/drive motor off and the machine stops;
• stop the brush by pressing the button (fig. 5, ref. 3);
• lift the lever (fig. 5, ref. 8) to raise the squeegee from the floor to prevent the continuous
pressure from warping the blades;
• remove the brushes (or drive disks) to prevent them from warping permanently;
• empty and clean the dirty water tank.

Some useful tips to get the most from your scrubber drier

•
In the event of particularly stubborn dirt on the floor, washing and drying can be performed
in two separate operations.
6.9.1. Prewashing with brushes or pads
• adjust detergent flow;
• press the brush button (fig. 5, ref. 3)
• lower the head;
• operate the drive lever to rotate the brushes;
• make sure the suction motor is off and the squeegee is raised;
• begin washing.
The flow of water must be adjusted in proportion to the desired advance speed. The
slower the machine moves forwards, the less water is needed.
Persist when washing particularly dirty points to give the detergent time to perform its
chemical action detaching and suspending the dirt and the brushes time to exert an
effective mechanical action.
6.9.2. Drying
Lower the squeegee and with the suction motor on, pass over the same area washed
previously. The result is equivalent to in-depth washing and subsequent ordinary
maintenance will take less time.
To wash and dry at the same time, operate the brush, water, squeegee and suction motor
simultaneously.
