To unpack the machine, carefully follow the instructions on the packing.
To move the machine manually, see the Pushing/Towing The Machine paragraph.
When the machine is delivered, check that the packing and the machine were not damaged during transportation.
in a damage claim.
Please check that the following items have been supplied with the machine:
– Technical documents:
• Scrubber-dryer Instructions for Use Manual
• Electronic battery charger manual (if installed)
• Scrubber-dryer Spare Parts List
– No. 2 lamellar fuses
– No. 1 battery connector (only for machines without on-board battery charger)

SAFETY
The following symbols indicate potentially dangerous situations. Always read this information carefully and take all necessary
precautions to safeguard people and property.
The operator’s cooperation is essential in order to prevent injury. No accident prevention program is effective without the total
cooperation of the person responsible for the machine operation. Most of the accidents that may occur in a factory, while working
or moving around, are caused by failure to comply with the simplest rules for exercising prudence. A careful and prudent operator is
the best guarantee against accidents and is essential for successful completion of any prevention program.

BEFORE MACHINE START-UP
WARNING!
When starting the machine, or before operating the One Touch button (43), make sure that there is no foreign
material between the deck and the tank assembly which could obstruct the deck movement. If the machine has
been turned off without lifting the deck, the deck would lift automatically at next machine start-up.
Brush or pad-holder removal/installation
According to the kind of cleaning to be performed, the machine
can be equipped either with the brush (A, Fig. 2) or the padholder (B) with pad (C) together with the appropriate deck.
1. Place the brush (A) or the pad-holder (B) under the deck
(7).
2. Place the user key (52) in the key reader (41), then press
the push-button (42) to start the machine.
3. Press the One-Touch button (43) to lower the deck onto the
brush.
4. Press the switch (45) to engage the brush.
5. To remove the brush, the deck must be lifted by pressing

Maintenance chapter).
4. Drive the machine to the working place, by starting it with both hands on the steering wheel (1) and by pressing the drive pedal
(2).
The drive speed can be adjusted from zero to maximum speed according to the pressure on the drive pedal (2).
5. The forward/reverse gear is selected with the relevant lever (49) which is at the right of the steering wheel.
NOTE
The driver’s seat (12) is equipped with a safety sensor, which allows the machine to be driven by pressing the pedal (2)
only when the operator is on the driver’s seat.
NOTE
The machine is equipped with an anti-skid safety system (display icon (51-J)) that reduces the speed when turning and
when the machine tilts laterally, irrespectively of the pressure on the pedal.
In this case, the reduction of speed is not a malfunction but a characteristic that improves the machine stability and
safety in every condition.
Stopping the machine
6. Stop the machine by releasing the drive paddle (2). It is not necessary to lock the machine during stopping or parking, because
the electromagnetic brake on the wheels turn on automatically when the drive pedal is not pressed.
7. Turn off the machine by pressing the push-button (42) and remove the user key (52).
NOTE
The machine is running without the user key (52) in the key reader (41), it automatically switches off after 10 seconds of
complete idle.
NOTE
If the machine is on but not working, it automatically turns off after 5 minutes.
CAUTION!
To reset the machine operation, lift the recovery tank assembly (17) and reconnect the battery connector (6).
