Display; Parking Brake; Machine Operation - Nilfisk SW4000 Instructions D'utilisation

ENGLISH

DISPLAY

The display (69) shows the machine working hours; the time counted is the one during which the main broom is moving.
NOTE
When the working hour count exceeds 999, hours are then displayed in thousands with two decimal digits (for example
1.23 = 1,230 hours).
By pressing the push-button (70) it is possible to shortly display the battery voltage in Volts, with one decimal digit.

PARKING BRAKE

1. Engage the parking brake by pressing the pedal (6) and engaging the lever (7).
2. Disengage the parking brake by pressing and releasing the pedal (6).
WARNING!
Before performing any maintenance, repair, cleaning or replacement procedure engage the parking brake.
Engage the parking brake when parking the machine on a slope.
WARNING!
Before leaving the machine unattained, be sure that the parking brake can stop the machine with a large safety
margin.

MACHINE OPERATION

1. Drive the machine to the work area as shown in the previous paragraph.
2. Lower the main broom with the lever (63), and the side brooms with the lever (64).
3. If equipped, turn on the dust guard system with the switch (82).
4. Drive the machine straight forward at a quick walking speed. Drive the machine slower when sweeping large amounts of dust
or debris or when safe operation dictates slower speeds. Overlap passes 10 cm.
5. To collect light and bulky waste materials, lift the front skirt by pressing the pedal (8); take into consideration that the machine
vacuum capability is reduced when the front skirt is lifted.
WARNING!
When operating on wet floors, it is essential to turn off the vacuum system by pressing the switch (65) to
prevent the dust filter from being damaged.
6. For machine proper operation, the dust filter must be as clean as possible. For cleaning it while sweeping, turn on the filter
shaker by pressing the lower side of the switch (65).
While working, repeat the procedure every 10 minutes on average (depending on the dustiness of the area to be cleaned).
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 any more.
7. The hopper (11) should be dumped after each working period and whenever it is full (see the procedure in the next paragraph).
CAUTION!
If the main broom motor overload warning light (77) flashes repeatedly while sweeping, there may be debris
that slows down the broom (for checking this, see the procedure in Main Broom Replacement paragraph, under
Maintenance chapter), or the pressure on the ground may be excessive (see the procedure in Main Broom
Height Check and Adjustment paragraph, under Maintenance chapter). If the overload persists, the brooms may
stop. In this case, stop and restart the machine to restore the broom operation.
