MACHINE OPERATION
1.
Start the machine as described in the previous
paragraph.
2.
Keeping both hands on the handlebar (2, Fig. C),
manoeuvre the machine and start the floor
scrubbing/drying.
(20DD-20DC versions only): By pressing the levers (10, Fig.
B), both clockwise and counterclockwise, the machine feeds
forward; reverse feed is not performed.
Traverse speed can be adjusted by turning the governor (11,
Fig. B).
To pull the machine backwards or to perform turns with a very
narrow radius, the traverse control has to be disconnected by
releasing the levers (10, Fig. B).
Machine drive controls
3.
Depending on the floor type, or on the use of the brush
or the pad-holder, the machine front drive speed and the
forward straightaway movement (without turning on the
right or on the left) can change.
They can be adjusted with two knobs (13 and 14, Fig. J)
on the brush, proceeding in the following way:
–
The machine moves towards the left by turning the
adjusting knob (14, Fig. J) counter-clockwise; the
machine moves towards the right turning the
adjusting knob clockwise.
–
The machine speed increases by turning the
adjusting knob (13, Fig. J) counter-clockwise; the
machine speed decreases turning the adjusting knob
clockwise.
TANK EMPTYING
Once the recovery water tank (4, Fig. G) is full, empty it in the
following way.
Recovery water tank emptying
1.
Stop the machine with the brush and suction switches
(5 and 6, Fig. B).
2.
Lift the brush/pad-holder with the pedal (20, Fig. C).
3.
Lift the squeegee with the lever (19, Fig. C).
4.
Bring the machine to the appointed disposal area.
5.
Empty the recovery tank with the hose (17, Fig. C). If the
cleaning is over, rinse the tank with clean water.
Solution tank emptying
6.
Carry out steps from 1 to 4.
7.
Empty the solution tank with the hose (18, Fig. C). If the
cleaning is over, rinse the tank with clean water.
Cylindrical brushes debris container emptying (for
cylindrical brushes deck only)
8.
Stop the machine with the related brush and suction
switches (5 and 6, Fig. B).
9.
With the cylindrical brushes deck (25, Fig. J) lowered,
remove the debris container (29) pulling it laterally with
the handle (30).
10. Empty the debris container (29, Fig. J), then install it and
engage the related retainers.
AFTER USING THE MACHINE
At the end of the work, before leaving the machine:
1.
Remove the brush/pad-holder as follow:
–
Brush/pad-holder
: with the brush/pad-holder deck
lifted, turn the brush switch (5, Fig. B) to “I” position;
after a few seconds, turn the switch back to “0”
position, releasing the brush/pad-holder.
–
Cylindrical brushes
: with the cylindrical brushes
deck lifted, unscrew the handwheels (28, Fig. J) and
remove the doors (27) pushing them down and
pressing on the handwheels.
Remove the cylindrical brushes (26, Fig. J).
Reinstall the doors (27, Fig. J) and screw the
handwheels (28).
2.
Empty the tanks (4 and 5, Fig. G) and the debris
container (29, Fig. J), following the instructions in the
previous paragraph.
3.
After using the machine, perform the maintenance
operations (see the Maintenance chapter).
4.
Leave the machine in a dry and clean place, with brush
and squeegee removed or lifted.
MACHINE LONG INACTIVITY
If you foresee that the machine will not be used for more than
30 days, proceed as follows:
1.
Perform the operations described in the After Using
the Machine paragraph.
2.
Disconnect the battery connector (25, Fig. C).
3.
Disconnect the battery positive terminal (+) directly from
the battery (+) pole.
FIRST PERIOD OF USE
After the first period of use (first 8 hours) it is necessary to
check that the fastening and connecting elements are
correctly tightened, that the visible parts are integral and that
there are no leaks.
CAUTION!
To avoid any damage to the floor surface, stop
the brush rotation with the switch (5, Fig. B)
when the machine stops in one place.
CAUTION!
Before lifting the brush/pad-holder, stop its
rotation with the switch (5, Fig. B).
NOTE
An automatic float cut-off system (7, Fig. G)
locks the suction system once the recovery
tank (4) is full.
The suction system locking is signaled by a
sudden increase in the suction motor noise
frequency.
