6.2 Description:
The washing function of the machine is obtained by the interaction of the cleaning solution with the dirt present on the floor. To facilitate and enhance this interaction, is used a system of mechanical rubbing which consists in a device which rubs on the floor. This device can be of various nature (pad or brush), in each case, its function is to mechanically remove the dirt from the ground and facilitate the reaction between the dirt and cleaning solu­tion. A direct current electric motor connected to a case of gear reduction provides the rotational movement of the brush coupling flange. To the flange is coupled the brush (or the pad holder provided with pad) that rotates together with the flange. After lowering the base to the ground, the brush touches and rubs on the floor providing the desired mechanical rubbing.

6.3 Adjustments
6.3.1 Fixing and adjustment plate
The brush deck must be free to move pivoted to its support so that the brush acts parallel to the floor. This allows the brush to evenly lean to the ground and perform its function properly. Requirements: Mounted brush, switched off machine.
Procedure:
• Hook the brush to the base.
• Loosen the adjustment nuts.
• Lower the brush deck to the ground
so that the brush lies uniformly and parallel to the floor.
• Tighten the adjustment nuts.
6.3.1-82 Loosen the nuts 6.3.1-83 brush deck to the ground
6.3.1-84 Tighten the nuts
6.3.2 Brush deck lifting cable
Adjust the lifting cable using the ap­propriate register on the sheath so that when the base is in the raised position
the brush has a chance to pass under the base in an easy manner. In any case, the lowest part of the deck, must have a height from the ground of at least 7 cm.
6.4 Maintenance and checks
6.4.1 Motor
Check (to perform every 150h)
The motor should rotate evenly and smoothly. It’s important that the reduc­tion case is not noisy and that the motor current consumption is not higher than the declared on the plate, regardless of the load which it is subjected. It is nec­essary that the motor carbon brushes are always in good condition and show no signs of abnormal wear.
Maintenance (to perform every 600h)
Motor carbon brushes replacement:
Procedure:
• Put the machine in safe conditions.
• Remove the brush deck from the ma-
chine.

7.2 Description
The machine dries the floor using an in­tegrated Drying System. After the wash­ing, the solution used with the mechan­ical action of the brush to remove the dirt, is collected by a system which vac­uum it out from the floor. The system is basically made by a vacuum motor which produces an underpressure in the system. This underpressure causes an air flow which flows in the whole vac­uum circuit. The air that flows in the squeegee (when it is lowered on the floor) allows it to collect the water on the floor mixing it with the water and, via the vac­uum system, is brought to the recov­ery tank. In the recovery tank the wa­ter mixed with the dirt stops and the air keep flowing throughout the circuit reaching the vacuum motor and being discharged in the environment via the exhaust manifold.

Machine Frame and Traction System
8.1 Structure
• Squeegee and Brushdeck Levers
• Steering column
• Front Wheel
• Frame
• Rear Wheels
• Traction Motor
8.2 Description
The frame is a unique structure in painted steel. On it are coupled the steering system including the levers for the activation of the drying system and mechanical friction system, and the traction system. The steering system is composed by a steering column con­nected to a steering wheel , which acts directly on the front wheel . The steer­ing is ensured by a pinion and a crown, connected by a chain. The pinion is welded directly onto the steering, while the crown is installed on the assembly front wheel. On top of the steering col­umn , there are the levers for the acti­vation of the squeegee and the mechani­cal friction system. To ensure the proper functioning of the two systems, in the steering column are installed some mi­croswitches that act directly on the af­fected systems. The traction of the ma­chine is guaranteed by an electric mo­tor installed in combination with a gear, whose output shafts act directly on the rear wheels of the machine, ensuring traction. The gear motor is equipped with an electrobrake which ensures the immobility of the machine when it is not moving. Both the front wheel the rear wheels are non-marking and antiskid.

Cleaning Solution Supply System
9.1 Structure
1. Solution Tank
2. Hoses
3. Water Valve
4. Solution Filter
5. Solenoid Valve
6. Distributor
9.2 Description:
The Cleaning Solution Supply System is made by a tank commonly called solution tank or clean water tank. In this tank the clean water is mixed with the detergent to create the cleaning solution that the machine will use to clean. The solution is then canalized to the filter and the water valve. The filter is used to stop debris that could stuck the hose system and compromise the proper functioning of the system, the water valve is used to adjust the solution that will fall on the floor in order to have the correct amount of solution required for washing. The water valve is placed upstream of the filter to allow the filter cleaning even with fully or partially full solution tank. Once passed through the water valve the solution arrive to the solenoid valve that blocks the delivery when the brush is not working and allow the flow while brush works. The end of the solution path is the distributor that canalizes the flow in the middle of the brush. The solution tank is also equipped with a drain hose to empty it in case of need.
