MACHINE START AND STOP
Start
1.
Prepare the machine as described in the previous
paragraph.
2.
Turn the ignition key (12, Fig. B) to “I” position without
pressing the forward gear pedal (3, Fig. C). Check if the
green warning light (7a, Fig. B) turns on.
If the yellow or red warning light (7b o 7c, Fig. B) turns
on, turn the key back to “0” position, then charge the
batteries (see the procedure in the Maintenance
chapter).
3.
Drive the machine to the working area, by keeping your
hands on the steering wheel and pressing the pedal (3,
Fig. C) on the front side to move forward and on the rear
side to move backward.
The drive speed can be adjusted from zero to maximum
speed according to the pressure on the pedal (3, Fig. C).
4.
Lower the brush/pad-holder deck and the squeegee with
the switch (6, Fig. B).
5.
Press the solution flow adjusting switches (10, Fig. B)
according to the type of cleaning to be carried out.
6.
Start scrubbing, by turning the steering wheel (2, Fig. C)
and moving the machine forward with the pedal (3).
7.
If necessary, adjust the working speed using the
maximum speed adjuster (11, Fig. B). The adjuster is
active only when the machine is operating (scrubbing
and/or drying).
Machine stop
8.
Release the pedal (3, Fig. C).
9.
It is not necessary to lock the machine during stopping
or parking, because the electromagnetic brake (27, Fig.
C) activates automatically when the forward gear pedal
is not pressed.
10. Lift the brush/pad-holder deck and the squeegee with
the switch (6, Fig. B).
MACHINE OPERATION
1.
Start the machine as described in the previous
paragraph.
2.
If necessary, adjust the solution flow sent to the brushes
with the switches (10, Fig. B).
Squeegee adjustment
3.
If necessary, stop the machine and adjust the balancing
handwheel (16, Fig. C) of the squeegee (12).
Working with brush/pad-holder extra pressure
function activated
4.
If the dirt on the floor proves to be particularly difficult to
clean, it is possible to work with an extra pressure of the
brushes/pad-holders on the floor by pressing the switch
(5, Fig. B).
5.
To return to normal pressure, press the switch (5, Fig. B)
again.
The switch (5, Fig. B) is active only when the deck (4,
Fig. C) is lowered and the warning light of the switch (4,
Fig. B) is on.
NOTE
The seat (25, Fig. C) is equipped with a safety
sensor, which allows the machine to be moved
with the pedal (3, Fig. C) only when the
operator is on the driver's seat.
NOTE
The machine is equipped with an anti-tilting
safety system that reduces the speed when
turning, irrespectively of the pressure on the
forward gear pedal.
The reduction of speed when turning is not a
malfunction but a characteristic that improves
the machine stability in every condition.
CAUTION!
To avoid any damage to the floor surface, stop
the brushes/pad rotation when the machine
stops in one place, especially when the
machine is working with the extra pressure
function activated.
NOTE
When the cylindrical brush deck is installed,
the extra pressure function is not active.
CAUTION!
In case of brush/pad-holder motor overload,
due to foreign material which prevent the
brushes/pad-holders from rotating, or to
excessively aggressive floors/brushes, the
safety system stops the brushes/pad-holders
after about one minute of continuous overload.
The overload condition is shown by the three
warning lights (7a, 7b, 7c, Fig. B) flashing
simultaneously.
If the overload takes place when scrubbing
with the extra pressure function activated, the
system automatically reduces the pressure of
the brushes/pad-holders thus deactivating the
extra pressure function. If the overload
persists, the brushes/pad-holders stop.
To start scrubbing again after a
brush/pad-holder stop due to overload, stop
the machine by turning the ignition key (12,
Fig. B) to “0” position. Restart the machine by
turning the ignition key to “I” position.
