1.5. DEMOLISHING THE
MACHINE
In order to protect the environment, proceed
in compliance with local standards in force.
When the appliance can no longer be used
or repaired, proceed with the separate dis-
posal of its components.
Electrical equipment cannot be disposed of as
urban waste and it is necessary
to dispose of it separately as in-
troduced by the special regulation
regarding the disposal of waste
originating from electrical equip-
ment (Italian Legislative Decree
no. 151 of 25/7/05 - 2002/96/EC
- 2003/108/EC).
The electrical equipment is marked with a sym-
bol showing a wheeled bin with a cross on it.
The symbol indicates that the equipment was
put on the market after 13 August 2005 and
that it must be disposed of separately.
In consideration of the substances and ma-
terials contained, inadequate or abusive dis-
posal of the equipment or its improper use
may cause damage or injury to persons and
the environment.
Disposal of electrical waste which does not
respect the standards in force leads to the
application of administrative sanctions and
penalties.

9.1.c - Using the machine
WARNING:
The machine can be operated only for 20
minutes consecutively.
Before using the machine again, keep it
switched off for 25 minutes at least.
- After having started the machine and se-
lected the type of cycle, start the cleaning
operation by pressing the levers (8) and
holding them pressed to start rotation of
the brush and the dispensing of water,
then push the machine by means of the
handles (10) in the handle bar (11).
N.B.:
Releasing the levers (8) stops the rotation of
the brush and the dispensing of water.
N.B.:
To avoid damaging the floor, do not use the
machine in a fixed position with brush rota-
tion activated
N.B.:
The correct way of cleaning and drying the
floor is to move the machine forwards. Mov-
ing the machine backwards damages the
blades as well as not allowing correct aspira-
tion of the water present on the floor.
- If necessary, adjust the quantity of wash-
ing water using the tap (12).
- Check the status of the battery charge by
the indicator (5).
9.1.d - End of use and switching off
- At the end of the cleaning operation and
before turning off the machine, stop the
dispensing of water and the rotation of
the brush by releasing levers (8) and
pressing the button (9) to continue with
the aspirator to remove all of the liquid
present on the floor, and then turn off the
aspirator by pressing button (7).
- Raise the squeegee (13) by pulling the le-
ver (6) and releasing it, the lever remains
in an upper position thus maintaining the
floor wipers in the raised position.
