Machine Operation - Nilfisk SW5500 Bedienungshandbuch

MACHINE OPERATION

1. Drive the machine to the work area as shown in the previous paragraph.
2. Start cleaning by lowering the main broom and activating the vacuum system with the One-Touch push-button (52).
3. (Optional) activate the DustGuard™ system with the corresponding push-button (68).
4. Lower the side brooms with the push-buttons (53) and (54, optional). If necessary, adjust the speed of the side brooms with the
+ and - push-buttons (55, icon on display 71-I).
NOTE
The brooms (18, 15 and 16) can be lowered and lifted even when the machine is moving.
When the brooms are lowered, the brooms, the vacuum system and the dust guard system (optional) automatically
activate only when the machine is moving.
NOTE
The side broom icons (71-F) keep the operator informed of the working configuration of the side brooms. When the icon
is present, the corresponding side broom is activated and deactivated together with the main broom via the One-Touch
push-button (52).
5. Start sweeping by driving the machine with the hands on the steering wheel (1) and by pressing the accelerator pedal (5). If
necessary, set the maximum speed with the push-buttons (58) and (59).
6. 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.
7. 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 push-button (56) to
prevent the dust filter from being damaged.
8. For machine proper operation, the dust filter must be as clean as possible. To clean it while sweeping, operate the filter shaker
by pressing the push-button (57).
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 anymore.
9. The hopper (12) should be dumped after each working period and whenever it is full (see the procedure in the next paragraph).
CAUTION!
The engine is equipped with a warning system to prevent damages to the engine itself in case the oil quantity in
the carter is insufficient. Before the oil level goes below the safety limit, the warning system automatically stops
the engine and displays the icon (71-R) on the multifunction display.
CAUTION!
In the event of an overload of one of the broom motors, due to foreign bodies blocking it or excessive pressure
of the broom on the ground (see procedure in the Main/Side Broom Height Check and Adjustment paragraph of
the Maintenance chapter), a safety system stops the motor.
