TECHNICAL INFORMATION

General description

This machine is a scrubber dryer for sweeping, washing and drying flat, horizontal, smooth or moderately rough, uniformly structured and obstacle-free floors in civil and industrial premises.‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​​‍⁠​​​‌​⁠​​‌‍⁠‌⁠‍​‌​​⁠‍⁠‌​‍‌‌‌‍⁠​‌​

The scrubber dryer spreads a solution of water and detergent in the correct concentration on the floor and then scrubs it to remove the dirt. By carefully choosing the detergent and brushes (or abrasive disks) from the wide range of accessories available, the machine can be adapted to a wide range of combinations of types of floor and dirt.

The machine incorporates a wet vacuuming system which dries the floor immediately after washing. The drying action is produced by the suction motor, which generates a partial vacuum in the dirty water tank. Squeegees mounted beneath the tank are designed to collect the film of dirty water with the machine moving in both forward and reverse directions.

• Adjust the position of the handle, referring to the section "Adjusting the handle rake angle".
• Fit the brush, referring to the section "Fitting the brush/pad driver".

Controls

The machine has the following controls and indicator lights:‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​‌​‌​​​‌​⁠​​‌‍‌‍‌‌‌‍​‍‌‍‌‌​‍⁠‍​⁠​​‍​

• Main switch (fig. 14, ref. 1): connects and disconnects electrical power to and from all functions of the machine.
• Battery charge indicator (fig. 15, ref. 1): consists of 3 Leds, red, yellow and green, showing the battery charge level. Possible charge level indications:
  • 100% battery: red, yellow and green LED on.
  • 30% battery: red and yellow LED on.
  • 10% battery: red LED on steadily.
  • 5% battery: red LED on blinking, battery completely flat, after a few seconds the brush and suction motors will be shut off;
• Brush control button (fig. 15, ref. 2): enables (Led alight) and disables (Led dark) operation of the "Brush" function; the brush does not start rotating until the "Brush control lever"(fig. 14, ref. 2) is operated.

• Suction control button (fig. 15, ref. 3): switches on (“Led alight”) and switches off (“Led dark”) the suction motor, which generates the vacuum needed to dry the floor after scrubbing. The motor comes into operation only when activated by way of the "Brush control lever".
• Detergent flow button (Fig.15-Ref.5): to enable, disable or change the flow of detergent solution, proceed as follows:
  • press the detergent flow button once, all three drops will light up and maximum flow will be enabled. When the button is pressed a second time, the flow is decreased and only two drops remain lit. Repeating the same procedure decreases the flow further until it stops, at which stage none of the drops will be lit.
  Flow is enabled only with the brush in operation.
• ECO button (fig.15, ref. 4): enables (Led alight) and disables (Led dark) ECO operating mode.

Working

• Press the main switch (fig. 16, ref. 1).
• Press the brush button or the ECO button (fig. 17, ref. 1), in addition to activating the brush, this will also enable the vacuum function and the flow of detergent solution.
• Lower the squeegee by operating the lever (fig. 16, ref. 2).
• Depress the brush control lever (fig. 16, ref. 3).
• Begin working.

• When work is in progress, check the thoroughness of the wash and regulate the flow of detergent solution accordingly, with the relative button (fig. 17, ref. 3).

In cases where floors are soiled with particularly stubborn dirt, scrubbing and drying operations can be performed in two separate stages.‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​‌​‍​​​‌​⁠​​‌⁠⁠​⁠⁠‍‌​​‍⁠​​‍​​​‍​‍⁠​​

Prewashing with brushes or pads:

• Raise the squeegee by operating the lever (fig. 16, ref. 2).
• Press the main switch (fig. 16, ref. 1).
• Press the brush control button (fig. 17, ref. 1).
• Switch off the vacuum function by pressing the suction control button (fig. 17, ref. 2).
• Depress the brush control lever (fig. 16, ref. 3).
• When scrubbing particularly dirty areas, give the detergent sufficient time to perform its chemical action of detaching and suspending the dirt in the film of water, and allow the brushes time to exert an effective mechanical action.

Drying:

• Lower the squeegee by operating the lever (fig. 16, ref. 2).
• Press the suction control button to activate the vacuum function, and pass over the area washed previously: this will produce an effect similar to a thorough scrub, with the result that subsequent routine maintenance work on the floor will be less time-consuming.

Removal of dirty water tank lid

• Release the lid of the dirty water tank by pressing the two sliding catches toward one another (fig. 19, ref. 1).
• Lift off the lid.

Installation of dirty water tank lid

• Place the lid on the tank.
• Apply downward pressure to the lid, sufficient to make certain that the two sliding release catches spring outwards and engage with the top of the dirty water tank (Fig.20).

Filling the water/detergent tank

The tank can be filled in two different ways:‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​‌​⁠​​​‌​⁠​​‌‌⁠‌⁠​​​⁠‌‌​‌‌‌​⁠​​‌‍⁠‌​

Tank installed on the machine:

• Turn off the machine at the main switch.
• Remove the cap of the detergent tank (fig.21, ref. 1).
• Fill the tank.

Tank removed from the machine:

• Turn off the machine at the main switch.
• Press in the two lateral tank retaining catches (fig. 22, ref. 1), separate the dirty water tank from the frame and set it down on the floor.
• Remove the cap of the detergent tank.
• Separate the detergent tank from the frame.
• Fill the tank (fig. 23).

Emptying the water/detergent tank

The tank can be emptied by proceeding as follows:

• Turn off the machine at the main switch.
• Take the machine to the disposal area.
• Press in the two lateral tank retaining catches (fig. 22, ref. 1), separate the dirty water tank from the frame and set it down on the floor.
• Separate the detergent tank from the frame.
• Remove the cap of the detergent tank.
• Empty the contents of the tank by way of the front opening (fig. 24).

Emptying the dirty water tank

An automatic float-controlled shut-off device mounted to the lid of the dirty water tank is designed to inhibit further operation of the vacuuming system when the tank is full. It is possible to recognize when the vacuuming system has been shut off, as the suction motor will suddenly become noisier in operation, and the floor will not dry as expected. In this situation, the operator must stop the machine and empty the dirty water tank, proceeding as follows:‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​‌‌​​​​‌​⁠​​⁠‌‌‍‍⁠‍​⁠‍​⁠​‌⁠‍‌‌​​⁠​⁠⁠

• Turn off the machine at the main switch.
• Take the machine to the disposal area.
• Press in the two lateral tank retaining catches (fig. 25, ref. 1), and separate the dirty water tank from the frame.
• Remove the cap of the dirty water tank (fig.26, ref. 1).
• Empty the tank (fig. 27).

Drive adjustment

The machine is equipped with a special mechanical drive device that exploits the friction created between brush and floor to generate forward movement.

The driving force produced by the device can be varied by turning the relative knob (fig. 28, ref. 1), which presents two sectors of different colour, one green and the other yellow:

• turning the knob to the position that exposes the green sector, the driving force is increased.
• turning the knob to the position that exposes the yellow sector, the driving force is decreased.
• To make the adjustment, proceed as follows:
• Turn off the machine at the main switch.
• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".

• Avoid the use of high pressure washers. Water could penetrate the electrical compartment or the motors, leading to damage or the risk of short circuit.
• Do not use steam, as the heat generated could cause plastic parts to lose their shape.
• Do not use solvents or hydrocarbon based products. These can damage the cowling and rubber components.

Cleaning the suction float

• Release the lid of the dirty water tank.
• Turn the lid over and check that the floats can move freely (fig. 29, ref. 1).
• Clean the seals with a moist cloth (fig. 29, ref. 2).
• Refit the lid.

Cleaning the water/detergent tank filter

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".
• Remove the filter and wash with water (fig. 30, ref. 1).

Cleaning the suction filter

• Remove the dirty water tank from the machine and set it on the floor, referring to the section "Emptying the dirty water tank".
• Remove the filter and wash with water (fig. 30, ref. 2).

Cleaning the front squeegee suction hose

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".
• Detach the hose from the diverter valve (fig. 31, ref. 1) and from the front squeegee (fig. 31, ref. 2).
• Wash the hose by directing water into the bore (fig. 32)
• Reattach the hose.

Cleaning the rear squeegee suction hose

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".
• Pull the handle up perpendicular to the machine.
• Lower the squeegee by operating the lever.
• Tilt the machine backwards and rest the handle on the floor.
• Detach the hose from the diverter valve and from the rear squeegee (fig. 33, ref. 1).
• Wash the hose by directing water into the bore (fig. 32)
• Reattach the hose.

Cleaning the diverter valve

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".
• Detach the front squeegee suction hose from the diverter valve.
• Detach the rear squeegee suction hose from the diverter valve.
• Release the retaining lever (fig. 35, ref. 1) and remove the cover of the diverter valve.
• Clean the chamber of the valve (fig. 36, ref. 1), removing any encrustations, and rinse with clean water; wipe the seals of the cover with a soft cloth.

Cleaning the squeegee

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".
• Pull the handle up perpendicular to the machine.
• Tilt the machine backwards and rest the handle on the floor.
• Clean the blades of both squeegees with a moist cloth (fig. 37, ref. 1).
• Clean the suction inlet port of both squeegees (fig. 37, ref. 2).

Squeegee adjustment

The squeegee is factory-adjusted to give an optimum drying action on different types of floor surface, but in the event that results do not meet expectations, there are further adjustments that can be made.‌‌​⁠⁠‌‍⁠‍​​‌‌​‍‌⁠​‌‍​​​​​‌‌⁠​​​‌​⁠​​​⁠‍‍‌‍⁠‍‌⁠‌‌⁠‌‌⁠‍‌‌‌⁠⁠‍​

To ensure a faultless drying action, the lip of the squeegee blade should deflect 45° along its entire length, relative to the floor surface; the height of the squeegee can be adjusted by raising or lowering the wheels (fig. 38, ref. 1).

Replacing the squeegee blades

The squeegee blades collect the film of water and detergent from the floor and prepare the way for perfect drying. With time, the constant wiping action causes the edge of the blade in contact with the floor to become rounded and cracked, with the result that drying is less thorough and the blade must be replaced. Proceed as follows:

• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section "Emptying the water/detergent tank" and "Emptying the dirty water tank".

• Pull the handle up perpendicular to the machine.
• Tilt the machine backwards and rest the handle on the floor.

Replacing the brush

The brush presents a number of tufts, coloured red, with bristles shorter in length than the rest (fig. 45). When the tufts of black bristles wear down to the same length as the red bristles, the brush must be replaced. For directions on replacement of the brush, refer to the sections “Releasing the brush/pad drive board" and "Fitting the brush/pad drive board".
