must be recharged.
•
Main switch - emergency button with key (ref. 2): enables or disables the power
supply to all the machine functions. It acts as a safety device. To start the machine
turn the proper key clockwise. To stop the machine press the button.
•
Brush/roller up-down button (ref. 5): when the arrow down is pressed, the head
moves down to the working position, the brush motor comes on automatically and the
solenoid valve is activated. Via this button, a variable pressure can be exerted on the
head during the work phase (according to how long the button is kept pressed), thus
adapting the cleaning power of the brushes to a wide range of different operating
conditions.
When the arrow up is pressed, the head moves up to the rest position, the brush
motors are switched off and the solenoid valve is de-activated.
•
Brush pressure indicator (ref. 8): indicates connections of brushes and pressure
exerted by the head (1 led on indicates beginning of brush connection; 2 leds on
indicate minimum pressure; 3 leds on indicate maximum pressure).
•
Brush release button (ref. 4): permits release of the brushes; press the button for a
couple of seconds: when the button is released, the brushes will be released.
•
Cock control lever (ref. 3): allows to adjust continuously the flow of solution sent to
the brushes. On turning it forward, the liquid outlet flow is increased.
•
Drive command lever (ref. 6): placed under the handgrip, when it is slightly pressed
upwards (the emergency button must be active), it starts the drive motor thus making
the machine move forward. When the lever is pressed down, the drive motor moves
the machine in reverse gear.
•
Squeegee lifting lever (ref. 11): it allows to raise (when lifted) or lower (when pushed
down) the squeegee. When it is pressed down, the suction motor is also switched on
for drying the floor.
•
Hour meter (ref. 7 - optional): displays the hours of work of the brush.
•
Parking brake pedal (ref. 12): engages (when pressed and moved to the right) and
disengages (when pressed and moved to the left) the parking brake.
•
Potentiometer (ref. 1): permits adjustment of the machine forward and reverse
speed; when the knob is turned clockwise the speed is increased.

Installing and adjusting the squeegee
The floor wiper, also called squeegee (fig. 2, ref. 8), is the first responsible for drying.
To install the squeegee on the machine proceed as follows:
1) Stop the machine and press the emergency button (fig. 8, ref. 2); engage the parking
brake by means of the pedal (fig. 9, ref. 5);
2) check that the squeegee supporting plate (fig. 9, ref. 2) is raised, otherwise lift it by
acting on the proper lever (fig. 9, ref. 6);
3) firmly push down the sleeve of the suction tube (fig. 9, ref. 4) into the squeegee;
4) slacken the two knobs (fig. 9, ref. 3) placed in the centre of the squeegee;
5) insert the two threaded dowels in the slots of the support (fig. 9, ref. 2);
6) fix the squeegee by tightening the knobs (fig. 9, ref. 3).
The blades of the squeegee are used to scrub from the floor the film of water and
detergent thus allowing a perfect drying. As long as time goes by the continuous scraping
rounds off and splits the sharp edge in contact with the floor, thus reducing the drying
efficacy and therefore requiring the replacement of the blades. Therefore, often check
their state of wear and tear.
To obtain a perfect drying action it is necessary to adjust the squeegee in such a way that
when it is in operation, the rear blade lip is bent about 45 degrees with respect to the floor
at all points. It is possible to adjust the inclination of the blades by screwing down the nuts
(fig. 9, ref. 1): by unscrewing the nuts the blade inclination is reduced, while by screwing
the nuts the blade inclination is increased.
Moreover, check that the suction hole of the squeegee is not clogged, to let dirty water to
