ENGLISH
24. Lower the suction inlet and side brooms by pressing the push-button (37, Fig. D).
CAUTION!
The suction inlet and brooms lowers only if the engine speed is at least 1,500 rpm.
25. Lower the 3rd broom by pushing the joystick (46, Fig. D) forward. If it is necessary to lift the broom while working, push the
joystick (46) rearward.
26. Check and, if necessary, top up the dust control system water tanks, and check which symbol (12, Fig. H) turns on:
• main tank and sub-tank are full
• main tank is empty and sub-tank is full
• main tank and sub-tank are empty. In this condition, the dust control system and high-pressure washing system turn off
after about 5 seconds.
!
• failure in the dust control system tank water level detection or visualisation system. Contact a Nilfi sk Service Center.
CAUTION!
A safety system turns of the water pumps if the water level in the tanks is insuffi cient for an interval of 10
seconds or more.
27. If necessary, open the dust control system valves (10, 11, 12, Fig. E), considering the following:
• Suction pipe dust control system nozzle valve (10, Fig. E): Open it always, except when the fl oor to be cleaned is wet. This
valve sends water also to the rear pipe dust control system nozzle (optional).
• Side broom dust control system nozzle valve (11, Fig. E): Open it when the fl oor is dry and dusty.
• 3rd broom dust control system nozzle valve (12, Fig. E): Open it when the fl oor is dry and dusty.
28. Turn on the dust control system water pump with the switch (27, Fig. D) according to the following procedure:
• When the switch is turned to the fi rst position, the nozzles sprinkle a medium quantity of water
(use it when there is little dust)
• When the switch is turned to the second position, the nozzles sprinkle the maximum quantity of water
(use it when there is a lot of dust)
CAUTION!
The machine is equipped with an automatic system that, when the water pump switch (27, Fig. D) is pressed,
allows for water supply to the nozzles only if the broom and suction fan rotation is enabled. In this case, activate
the fan manually with the switch (30, Fig. D) to use the rear pipe, so that water can be supplied by the nozzles
using the water pump switch (27).
29. Disengage the parking brake with the lever (13, Fig. E).
30. Start sweeping, by keeping the hands on the steering wheel (28, Fig. D) and gradually pressing the pedal (26), on the front
side to move forward and on the rear side to move backward.
The drive speed can be adjusted from zero to maximum speed by increasing the pressure on the pedal.
While working, the machine picks up both light materials such as dust, paper, leaves, etc. and heavy materials such as stones,
bottles, etc.
WARNING!
The machine is equipped with a safety system that stops the movement (machine in neutral) and disables
the hydraulic functions when the operator is not on the driver's seat (14, Fig. E) for more than 3 seconds. The
movement and the hydraulic functions restarts automatically when the operator returns on the driver's seat (14).
Only the suction fan for the manual rear pipe, and the high-pressure pump for the washing system can be used
in these conditions.
NOTE
All brooms (19, 20, 21, Fig. G) can be lifted or lowered when the machine is moving.
The brooms rotate even when they are lifted.
WARNING!
Do not leave the sweeper stationary with the suction inlet lowered and the brooms rotating.
