Machine Operation; Hopper Dumping - Nilfisk RS 501 Manuel D'utilisation

MACHINE OPERATION

1. Avoid stopping for a long time with the machine in the same position and the brooms rotating: this could create unwanted
marks on the fl oor.
Bulky debris collection
2. To collect bulky debris, lift the front skirt (24, Fig. G) with the switch (13, Fig. E).
Note that, while the skirt is lifted, the machine suction power decreases.
To lower the front skirt (24, Fig. G), press the switch (13, Fig. E) again.
3. If necessary, to collect bulky debris, it is also possible to remove the front skirt (24, Fig. G); remove it according to the following
procedure:
• Lift the brooms, then stop the machine and turn off the engine.
• Remove the clip (1, Fig. H) and disconnect the tie rod (2) from the skirt (3).
• Remove the skirt (3) by withdrawing it from the hinges (4).
• Turn on the machine and start working again.
• Install the skirt (3) in the reverse order of removal, after stopping the machine and turning off the engine.
4. If necessary, adjust the broom speed with the knob (28, Fig. E) (optional).
NOTE
When the hopper is full, the machine cannot collect dust and debris anymore.
5. After each working cycle, and when the hopper (12, Fig. G) is full, it must be emptied. For the relevant procedure, see the next
paragraph.

HOPPER DUMPING

The maximum hopper dumping height is 1,460 mm.
Dump the hopper according to the following procedure.
Turn off the dust control system water pump with the switch (19, Fig. D).
1.
2. If open, close the dust control system valves (8 and 9, Fig. E).
3. Lift the safety fl ange (24, Fig. E), then lift the suction inlet and side brooms with the lever (12).
4. Turn off the suction fan with the lever (14, Fig. E).
5. Drive the machine to the appointed dumping area.
WARNING!
Perform the hopper dumping on a solid and level ground, to avoid machine unbalance.
Keep people away from the machine and especially from the hopper (12, Fig. G).
6. Lift the safety fl ange (23, Fig. E), then lift the hopper (12, Fig. G) with the lever (10, Fig. E).
WARNING!
Do not move the machine when the hopper is lifted!
If machine movement with lifted hopper cannot be prevented, be sure to drive slowest possible speed to avoid
lateral instability.
7. Open the hopper lid (21, Fig. G) by pressing the switch (28, Fig. D). Keep the switch pressed until the lid opens completely,
then dump the debris from the hopper. The warning light of the switch (28, Fig. D) turns on when the opening/closing latch of
the hopper lid (21, Fig. G) is open.
8. When the dumping is completed, lift the safety fl ange (23, Fig. E), then lower the hopper (12, Fig. G) completely with the lever
(10, Fig. E). Keep the lever activated until the warning light (26, Fig. D) turns off, which means that the hopper is completely
lowered.
9. If necessary, check for hopper fi lter clogging, according to the following procedure:
• Engage the parking brake and turn off the engine.
• Lift the hopper lid manually and secure it with the support rod (8, Fig. F).
• As shown in the Maintenance chapter, remove the fi lters (6 and 7, Fig. F) and check for clogging. If the fi lters are clogged,
clean them according to the relevant procedure. Install the fi lters.
• Disengage the support rod (8, Fig. F) and place it in its housing.
10. Close the hopper lid (21, Fig. G) by pressing the switch (28, Fig. D). Keep the switch pressed until the lid is completely closed.
The machine is ready to start working again.
