STARTING UP THE MACHINE (SCRUBBING/DRYING)

1. Press the lever (8) and turn the handlebar (1), adjusting its position and inclination as preferred.
2. Ensure that the park pedal (10) is lowered, then push the machine over to the area to be cleaned.
3. Lift the park pedal (10) to bring the brush/squeegee unit in contact with the floor.
4. Press the switch (2) to start the machine.
5. Press the solution push-button (3) according to the type of cleaning to be performed:

• Left LED on - for normal dirt

• Right LEDs on - for heavy dirt

1. Manoeuvre the machine with your hands on the grip handles (6) and start scrubbing/drying the floor.

NOTE

The grip handles (6) have sensors which allow the brush and solution to be started up only when the operator has their hands on at least one of the grip handles.

1. If necessary, deactivate the vacuum system by pressing the push-button (4, LED off), then press it again to reactivate it (LED on).
2. To collect medium-large debris, lift the front squeegee by pressing the lever (7).

To keep the front squeegee lifted, press the lever (7) and lock it with the push-button (9-A).

1. If necessary, in order to use the handlebar allowing it to tilt, press the lever (8) and lock it with the button (9-B).

NOTE

To unblock the function of the push-buttons (9-A, 9-B) and return to the lowered front squeegee and fixed handlebar, briefly press the squeegee lever (7) or the handlebar inclination lever (8).

1. For floors with particularly tough dirt, the pressure of the brush on the floor can be increased by turning the knob (19) to the left. Turn the knob (19) to the right to decrease the pressure.

NOTE

For correct scrubbing/drying of floors at the sides of the walls, Nilfisk suggests to go near the walls with the right side of the machine as shown in figure 3.

NOTE

If applicable, to better dry the grout lines between the tiles, move in a diagonal direction with respect to the floor layout, as shown in figure 4.

CAUTION!

In the event of a brush motor overload, the battery symbol LEDs (5) will flash simultaneously. If the overload persists, the brush stops.

To start scrubbing again after a brush stop due to overload, turn off and then on the machine with the push-button (2).

CAUTION!

To avoid damaging the floor surface, do not use the brush without the solution and, when the machine is not operating, stop the brush rotation by releasing the grip handles (6).

CAUTION!

Machine must always be used with the solution; it is forbidden to use the machine with no solution. If the machine is used with no solution, the brush automatically stops after 1 minute.

BATTERY CHARGE LEVEL

The battery charge level can be viewed on the battery icon LEDs (5).

The battery charge percentage depends on the number of LEDs lit, as shown in the figure 5.

BATTERY CHARGING

CAUTION!

Charge the battery when only 5, or less, LEDs are lit on the battery symbol (5).

When the battery is discharged, charge is as soon as possible, as that condition makes its life shorter. Check for battery charge at least once a week.

1. Drive the machine to the appointed recharging area.
2. Ensure that the machine is off.
3. Plug the battery charger cable plug (29) into the machine socket and the power supply cable plug into a mains socket (the mains voltage and frequency must be compatible with the battery charger values shown on the data plate).

NOTE

When the battery charger is connected to the electrical mains, all machine functions are automatically cut off.

During charging, one of the 6 LEDs of the battery icon (5) will remain steadily on to indicate the percentage of charging performed, while the other LEDs (to the left of the LED which is on steadily) will flash sequentially.

1. When the 6th LED of the battery icon (5) is lit steadily, battery charging is complete.
2. Disconnect the battery charger from the mains and from the machine socket (29).
3. Open the battery compartment cover (26) and place the battery charger in its tray (28).
4. Close the battery compartment (26).

CAUTION!

Do not connect the batterycharger repeatedly to a fully charged battery. Any abuse could lead to permanent battery lock for safety reasons. To check the battery charge status, use the appropriate push-button (D, Fig. 8) on the battery, or switch on the machine.

CHARGING THE BATTERY OUT OF THE MACHINE

1. Remove the battery (27) from the machine as shown in the Removing the Battery paragraph.
2. Place the battery in the appointed recharging area.
3. Plug the battery charger cable plug (B) into the battery socket (A, Fig. 8) and the power supply cable plug into a mains socket (the mains voltage and frequency must be compatible with the battery charger values shown on the data plate).
4. During charging, one of the 6 green LEDs (C) will remain steadily on to indicate the percentage of charging performed, while the other LEDs (to the left of the LED which is on steadily) will flash sequentially.
5. When the 6th LED (C) is lit steadily, battery charging is complete.
6. Disconnect the battery charger from the mains and from the battery.

NOTE

When the battery is not connected to the battery charger, you can see the battery charge level by pressing the button (D) briefly. The number of green LEDs (C) turned on is proportional to the battery charger level percentage.
