be perfectly drained from the floor.
6.3 Moving the machine
To displace the machine do as follows:
• lift the squeegee;
• raise the head by pressing the brush up-down button (fig. 8, ref. 5) on the arrow up;
• disengage the parking brake via the pedal (fig. 8, ref. 12);
• insert the key to release the emergency button (fig. 8, ref. 2);
• below the handgrip is a lever (fig. 8, ref. 6): by pulling the lever up (fig. 10, ref. 2) or
pressing it down (fig. 10, ref. 1), according to whether you wish to move forward or
back, the drive motor is switched on and the machine will begin to move;
• adjust the running speed via the potentiometer (fig. 8, ref. 1);
• once you have reached your destination, engage the parking brake via the pedal (fig.
8, ref. 12).
WARNING
Never leave the machine unmanned or parked with the parking brake disengaged
or the key inserted in the emergency button. Do not engage the parking brake when
the machine is moving.
6.4 Installing and replacing the brushes / drive discs / rollers
WARNING
Do not work if the brushes or drive discs are not perfectly installed.
6.4.1 Brush head (models 60-70-80)
Removing:
• raise the head by pressing the brush up-down button (fig. 8, ref. 5) on the arrow up;
• press the brush release button (fig. 8, ref. 4) for a couple of seconds: when the button
is released, the brushes will be released.
Fitting:
• position the brushes side by side at the front of the machine;
• move forward with the machine until the head is positioned above the brushes and
they are centred;
• press the brush up-down button (fig. 8, ref. 5) on the arrow down and keep it pressed
until the second led of the brush pressure indicator comes on (fig. 8, ref. 8); in this
phase the brush motor may come on and then switch off for a few moments: this is a
normal part of the brush engagement procedure.
WARNING
In particular conditions, the brushes may not engage correctly. In this case the
head will vibrate. The brushes must be disassembled and refitted.
If you wish to use the ABRASIVE DISCS instead of the brushes, they must firstly be fitted
on the drive discs: rest the pad on the drive disc, placing it exactly in the centre, and fix it
with the center lock ring nut. The drive discs must then be fitted on the machine following
exactly the same procedure as for the brushes.
WARNING
Fully tighten the drive disc flange via the handle provided in order to prevent the
flange dragging on the ground and damaging the floor.
6.4.2 Roller head (roller models R)
Disassembly:
• press the roller extraction buttons (fig. 11, ref. 4);
