BATTERY INSTALLATION AND BATTERY TYPE SETTING (WET /GEL/ AGM/
DIS/EXI/FUL/OPT/ENE(TPPL))
Battery Installation
1. Make sure that the machine is turned off with the ignition key and the parking brake is engaged.
2. Tip back the cover (31, Figure 2) carefully.
3. The machine is equipped with battery cables suitable for installing 4X6V batteries. Carefully put the batteries into the
compartment, then install them correctly.
4. Route and install the battery cables as shown in (Figure 6), then carefully tighten the nut on each battery terminal.
5. Place the protection cap on each terminal, and then connect the battery connector to the connector on the machine.
6. Turn back the cover carefully.
Battery type setting (WET/GEL/AGM/DIS/EXI/FUL/OPT/ENE(TPPL))
Access to select battery mode
According to the type of batteries (WET/GEL/AGM/DIS/EXI/FUL/OPT/ENE(TPPL)), set up the machine as follows:
7. Press vacuum button (A, Figure 7) and
pump button (B, Figure 7) at the same
time.
8. Insert ignition key (C, Figure 7) and turn
it to "I".
9. Several seconds later the system enters
select battery mode (Figure 7).
10. Release both vacuum button (A, Figure 7)
and pump button (B, Figure 7).
11. Press vacuum button (A, Figure 7) and
pump button (B, Figure 7) to select
battery type (E, Figure 7).
12. Press headlight button (D, Figure 7), about 1 second later the screen displays "Update OK", indicating that battery type is set up,
then restart machine. (C, Figure 7).
Battery charging
Fully charge the batteries (see the procedures in Maintenance chapter).
Battery discharging
1. When the battery icon displays full battery level (G, Figure 8), the batteries are fully charged.
2. When the battery icon displays low battery level (H, Figure 8), the batteries must be charged. Several seconds after the low
battery level is displayed, the Main broom/Side broom/Vacuum/Pump/Filter shaker motors are automatically turned off, while
the drive system remains on. Drive the machine to the designated charging area to charge immediately.
3. When battery voltage is very low, an error warning “Battery VOL Low” (I, Figure 8) will flash on the screen. Main broom/Side
broom/Vacuum/Pump/Filter shaker motors are automatically turned off, and the drive system is also turned off to protect the
batteries.

BEFORE MACHINE START-UP
Checklist
1. Have a full knowledge of the machine operating controls and
their functions.
2. Sit on the seat (A, Figure 9), insert the ignition key (C, Figure
9), and start the machine. (See the procedures in the following
paragraph)
3. Check the battery level. If the battery icon on the LCD (G,
Figure 9) is of 5 bars, the batteries are fully charged for use. If
it is of 1 bar or less, batteries must be charged before operation.
(Refer to Maintenance chapter for battery charging)
4. Check the parking brake (F, Figure 9). The brake must hold its
setting (locked) firmly without easily being released (report all
defects immediately to Nilfisk Service Center).
5. Check the flap pedal (E, Figure 9) for proper operation.
6. Press the accelerator pedal (D, Figure 9) slightly then release it
to check if the machine can be steered forward and stopped.
7. To ensure safety, confirm the machine can be stopped
immediately when pressing the emergency stop button (B,
Figure 9). Turn the emergency stop button to reset it.
WARNING!
If the pedal is “spongy” or fades under pressure
without an efficient braking force, do not drive
the machine (report all defects immediately to
Nilfisk Service Center).
8. Make sure that there are no open covers/hoods and that the
machine is in normal operating conditions.
9. Make sure that the hopper (H, Figure 9) is properly closed.
Cleaning planning
1. Arrange long runs with a minimum of stopping or starting.
2. Allow a small amount of broom path overlap to ensure complete coverage.
3. Avoid making sharp turns, bumping, or scraping the side of the machine.

STARTING AND STOPPING THE MACHINE
Preliminary operations
1. Sit on the driver’s seat (A, Figure 10) and adjust its position with the lever (C, Figure 10) to allow easy reach of all controls.
NOTE
The driver’s seat (A, Figure 10) is equipped with
a safety sensor, which allows the machine to be
driven only when the operator is on the driver’s
seat.
Starting the machine
1. Sit on the seat (A, Figure 10), insert the ignition key (J, Figure
10), and turn it to “I”.
2. Disengage the parking brake and drive the machine to the
working area.
3. Press one-button start button (M, Figure 10) to start the machine,
the side brooms and main broom are lowered to the floor
automatically.
4. Press the accelerator pedal (E, Figure 10), drive the machine
forward or backward with steering wheel (B, Figure 10) and
forward-reverse button (L, Figure 10). Driving speed can be
adjusted with speed adjusting knob (N, Figure 10). Main/side
brooms and vacuum motor begin to work.
5. Adjust side broom speed with side broom speed adjusting knob
(I, Figure 10) based on cleaning requirements.
6. The USB charging port (D, Figure 10) can be used to charge
mobile phone or pad when ignition key (J, Figure 10) is turned to
“I”.
7. Press the horn button (K, Figure 10) to warn people when
necessary.
NOTE
The main broom and side brooms (F and H,
Figure 10) can be lowered and lifted even when
the machine is moving.
The main broom and side brooms do not rotate
when they are lifted.
8. Start sweeping by turning the steering wheel (B, Figure 10) and
driving the machine forward with the accelerator pedal (E, Figure
10).
Stopping the machine
9. Release the accelerator pedal (E, Figure 10), and the machine stops moving.
10. Press one-button start button (M, Figure 10) again to turn off brooms, vacuum motor and pump. The main broom and side brooms
are lifted from the floor automatically. The vacuum system is turned off after a delay of several seconds.
11. Turn the ignition key to “O”.
12. Engage the parking brake.

PARKING BRAKE
1. Engage the parking brake by pressing on the front of the pedal (A, Figure
11) and engaging the lever (B, Figure 11).
2. Disengage the parking brake by pressing on the back of the pedal (C,
Figure 11) and releasing it.
WARNING!
Before performing any maintenance, repair, cleaning or
replacement procedure, engage the parking brake.
Don’t park the machine on a ramp.
MACHINE OPERATION
WARNING!
When using the machine on slopes, follow the maximum gradient values marked on the machine (see
“Technical Data” chapter).
WARNING!
Pay careful attention when operating the machine at high speed: sudden steering could cause this three-wheel
machine to become unstable due to weight distribution. Always reduce the speed before steering.
1. Drive the machine to the work area as shown in the previous paragraph.
2. Drive the machine straight forward at high speed. Drive the machine slower when sweeping a large amount of dust or debris or
when safe operation requires slower speed. To achieve optimal results, overlapping sweeping paths by over 10 cm (4 inches) is
recommended.
3. Avoid stopping the machine in the same position for a long time with the brooms rotating: this could create unwanted marks on
the floor.
4. To collect light and bulky waste materials, lift the front blade by pressing the flap pedal (H, Figure 10); take into consideration
that the machine vacuum capability is reduced when the front blade is lifted.
CAUTION!
When operating on wet floors, it is essential to turn off the vacuum system by pressing the vacuum button (A,
Figure 12) to prevent the dust filter from being damaged.
5. For machine proper operation, the dust filter must be as clean as possible. To
clean it while sweeping, turn on the filter shaker by pressing the filter shaker
button (B, Figure 12).
During this operation the vacuum motor is automatically shut off.
After cleaning the filter, the vacuum system resumes working automatically;
then start sweeping again.
While working, “filter auto cleaning” mode can be activated by pressing filter
shaker button (B, Figure 12) for 1 second, which can repeat the filter cleaning
procedure every 10 minutes on average (depending on the dustiness of the
area to be cleaned, interval can be set from 1 to 60 minutes, parameter setting
refer to the Service Manual).
NOTE
This procedure can also be performed when the machine is
moving.
CAUTION!
When the dust filter is clogged and/or the hopper is full, the machine cannot collect dust and debris anymore.
6. The hopper (D, Figure 13) should be emptied after each working cycle and whenever it is full (see the procedure in the following
paragraph).
