Setting the machine to working mode
Set the machine to working mode according to the following procedure:
1. Start the engine as shown in the relevant paragraph.
2. Check that the hopper (7, Fig. G) is lowered and that the warning light (18, Fig. D) is off.
3. Bring the 3rd broom safety arm from the position (1, Fig. H) (engaged) to the position (2) (disengaged).
4. Gradually bring forward the engine throttle lever (16, Fig. E) and set the engine speed on the display (17, Fig. D) to:
• Minimum 1,800 rpm
• Maximum 2,030 rpm
CAUTION!
If the engine speed exceeds 2,050 rpm in working mode, a safety system stops the broom rotation.
5. Turn on the suction fan with the lever (8, Fig. E).
6. Start the side broom rotation by turning the switch (29, Fig. D) to the fi rst position, and the 3rd broom rotation by turning the
switch (29) to the second position.
7. Lower the suction inlet and side brooms by pressing the push-button (37, Fig. D).
NOTE
Side brooms lower only if the suction fan is on.
CAUTION!
Do not leave the sweeper stationary with the suction inlet lowered and the brooms rotating.
8. Shift the 3rd broom arm to working mode, by moving the joystick (46, Fig. D) to the right/left.
9. Lower the 3rd broom by pushing the joystick (46, Fig. D) forward.
10. If necessary, open the dust control system taps (10, 11, 12, Fig. E), considering the following:
• Suction pipe dust control system nozzle tap (10, Fig. E): Open it always, except when the fl oor to be cleaned is wet.
• This tap sends water also to the rear pipe dust control system nozzle (optional).
• Side broom dust control system nozzle tap (11, Fig. E): Open it when the fl oor is dry and dusty.
• 3rd broom dust control system nozzle tap (12, Fig. E): Open it when the fl oor is dry and dusty.
11. 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)
12. Disengage the parking brake with the lever (13, Fig. E).
13. 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.
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.
