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).
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).
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

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.
Once the recovery water tank (4, Fig. G) is full, empty it in the
following way.

– Cylindrical brushes: with the cylindrical brushes
deck lifted, unscrew the handwheels (28, Fig. J) and
remove the doors (27) pushing them down and
