Seat backrest adjustment: Make sure you sit upright and that your back and that your lower back and spine are at 90°. Use the lever (1) located on the left side of the seat (Fig. 1) to adjust the backrest of the
seat.
Driving position adjustment: The seat should always be positioned using the pedals as a reference. Act on the lever (2) located on the lower part of the seat (Fig. 2) to adjust the seat sitting.
N.B.: The distance should be adjusted so that with the pedals fully pressed to the oor the knees are slightly bent (about 120°).
N.B.: Adjust the distance of the seat so that when pressing the brake pedal it goes as far as it can. This operation should be done with the machine running so as to pressurise the braking system.
N.B.: If the knee is not bent enough, it is too far from the steering wheel, if however the knee is bent almost 90°then it is too close to the steering wheel.
N.B.: The feet should be positioned keeping the heels on the footrest, the sole of the foot directly below the ngers should push the pedals.
N.B.: The ideal driving position is that which allows you to grip the steering wheel correctly with the palms slightly lower than the shoulders. With a good grip on the steering wheel, the elbows should be
bent by about 120°. They should be at least 30 cm or 11.81 in between the middle of the steering wheel and our breastbone. In any case, this distance should be no more than 45 cm or 17.72 in.
Adjusting the armrests (optional): The armrests should be inclined to make using the machine comfortable.
N.B.: To adjust the armrest use the runner (3) under it (Fig. 3).
N.B.: Taking the right armrest as a reference, if the wheel is turned outwards the inclination of the armrest is increased. Taking the left armrest as a reference, if the wheel is turned inwards the inclination of
the armrest is increased.
Wear the seatbelt correctly (optional): The machine has a sub-abdominal safety device that allows the operator to be anchored to the driver's seat. To secure the safety belt, rst of all you need to be sitting in the
drier's seat, take the mobile part (4) of the belt, wrap it round the abdomen and insert the mobile part () in the slit in the xed part (5) (Fig. 4).
N.B.: Adjust the horizontal part of the belt so it is as tight as possible on the pelvis. The belt should be pulled and put as low as possible on the pelvis bone, and not on the belly.

Transfer function:
The machine can be moved from one work area to another with the selector switch in transfer mode. The only main actuator active is that of the traction hub
motor.
Drying function:
With the selector in drying mode it is possible to dry the previously washed portion of the oor. The main actuators active are those of the traction hub motor
and the vacuum motor. When the drive pedal is pressed, the squeegee is brought into working position (in contact with the oor) and the vacuum motor will
start working in full working order. If the machine is stopped and the drive pedal is released during the operation, the squeegee body will remain in contact
with the oor for a few seconds, after which it will raise up from the ground to go back to its rest position. For all these phases the vacuum motor will continue
to operate, only after a few seconds that it has returned to its work position will it switch o󰀨, this is to allow the motor to collect all the liquid in the vacuum
hose. During these phases, the symbol of the vacuum motor on the instrument panel display will blink, and it will only stop when the squeegee is in its rest
position and the vacuum motor is o󰀨. If reverse is carried out with this program active, the squeegee will move to the rest position, the vacuum motor will
keep working for a pre-set time and then it will switch o󰀨.
Scrubbing with Drying function:
With the selector in the scrubbing with drying mode it is possible to both scrub and dry the oor at the same time. The main actuators active are those of
the traction hub motor brush head gearmotors and vacuum motor. When the drive pedal is pressed, both the brush head and the squeegee will move to the
working position, and as soon as it is in contact with the ground the brush head gearmotors and the vacuum motor start working in full working order. If the
machine stops and the foot pedal is released during the operation, the brush head body will start to rise to return to the rest position, and after a period of
time the gearmotors will switch o󰀨. The squeegee body will stay in contact with the oor for a few seconds, after which it will raise up from the ground and
return to its rest position. For all these phases the vacuum motor will continue to operate, only after a few seconds that it has returned to its rest position will
it switch o󰀨, this is to allow the motor to collect all the liquid in the vacuum hose. During these phases, the symbol of the vacuum motor on the instrument
panel display will blink, and it will only stop when the squeegee is in its rest position and the vacuum motor is o󰀨. If reverse is carried out with this program
active, the squeegee will move to the rest position, the vacuum motor will keep working for a pre-set time and then it will switch o󰀨.
Scrubbing without drying function:
With the selector in scrubbing without drying mode, it is possible to scrub the oor without vacuuming the detergent solution applied. The main actuators
active are those of the traction hub motor and the brush head gearmotors. When the drive pedal is pressed, the brush head will move to the working position,
and as soon as it is in contact with the ground the brush head gearmotors start working in full working order. If the machine stops and the foot pedal is
released during the operation, the brush head body will start to rise to return to the rest position, and after a period of time the gearmotors will switch o󰀨.
The drying without scrubbing operation should only be carried out if the machine was previously used to carry out a
scrubbing without drying operation.
