CLEANING THE BRUSH HEAD BODY BRUSHES
Careful cleaning of the brush guarantees better cleaning of the oor as well as a longer brush head gearmotor lifespan. To clean the brush, proceed as follows:
1. Take the machine to the designated maintenance place.
NOTE: the place designated for this operation must comply with current environmental protection regulations.
2. Select the “TRANSFER” function using the knob (1) (Fig. 1).
3. When the button (2) on the control panel (Fig. 2) is pressed for the rst time, the conrmation request symbol (Fig. 3) will appear in the control display.
4. Pressing the button (2) again will activate the brush release function.
N.B.: Once the release sequence has been activated, it is not possible to activate other functions or move the machine.
CAUTION: During this operation, check there are no people or objects near the brush.
5. Clean the brush under a stream of running water to remove any impurities from its bristles. Check the wear status of the bristles and replace the brushes if they are excessively consumed (the bristles' protrusion
must not be less than 10 mm; this distance is indicated on the brush by the yellow band). In order to replace the brushes, see the section titled “INSTALLING THE BRUSH HEAD BRUSHES”.
N.B.: you are advised to invert the right and left-hand brushes every day.
ATTENTION: If the brushes are not new however, and have deformed bristles, it is better to reassemble them in the same position (the right-hand one on the right, and the left-hand one on the left),
to prevent the dierent inclination of the bristles producing an overload on the brush motor as well as excessive vibrations.
