Setting the machine to working mode
Set the machine to working mode according to the following procedure:
18. Start the engine as shown in the relevant paragraph.
19. Check that the hopper (6, Fig. G) is lowered and that the warning light (3, Fig. D) is off.
20. Bring the 3rd broom safety pin from the position (1, Fig. H) (engaged) to the position (2) (disengaged), by pulling and turning
the relevant lever.
21. 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.
22. Shift the 3rd broom arm (23, Fig. G) from closed position to opened position by pushing the joystick (46, Fig. D) to the right.
The shifting operation will stop automatically when the end of stroke is reached.
WARNING!
It is possible to shift to the left or to the right the 3rd broom arm (23, Fig. G) safely, only when the arm extension
(22) is to the left or right end of stroke.
In this situation the arm shifting is limited by proper safety devices.
Otherwise, an excessive shifting can damage the machine or affect its stability.
It is therefore advisable to bring always the 3rd broom arm extension (22, Fig. G) to the left or right end of
stroke.
23. Prepare the machine for cleaning to the right or to the left according to the following procedure.
For cleaning to the right:
• With the spring-return switch (34, Fig. D), check that the 3rd broom arm extension (22, Fig. G) is to the right end of stroke.
Otherwise bring it to the above-mentioned position by pressing and holding the switch (34, Fig. D).
• Select the counter-clockwise rotation of the 3rd broom with the selector (25, Fig. D).
• Adjust the 3rd broom tilting angle in order to push the debris towards the suction inlet. To obtain the correct tilting, use the
switch (22, Fig. D) and set the broom (1, Fig. AK) as shown in the fi gure (the fi gure shows the 3rd broom as viewed from
the driver's seat).
For cleaning to the left:
• Press and hold the spring-return switch (34, Fig. D) to shift the 3rd broom arm extension (22, Fig. G) to the left end of
stroke. The shifting operation will stop automatically when the end of stroke is reached.
• Select the clockwise rotation of the 3rd broom with the selector (25, Fig. D).
• Adjust the 3rd broom tilting angle in order to push the debris towards the suction inlet. To obtain the correct tilting, use the
switch (22, Fig. D) and set the broom (2, Fig. AK) as shown in the fi gure (the fi gure shows the 3rd broom as viewed from
the driver's seat).
24. Gradually bring forward the engine throttle lever (16, Fig. E) and set the engine speed on the display (17, Fig. D) to the
following value:
• minimum 1,800 rpm
• maximum 2,000 rpm
CAUTION!
If the engine speed exceeds 2,050 rpm in working mode, a safety system stops the broom rotation.
25. Turn on the suction fan with the switch (30, Fig. D).
26. Lower the suction inlet and side brooms by pressing the push-button (37, Fig. D).
27. 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.
28. Check and, if necessary, top up the dust control system water tanks, and check which one of the three warning lights (49, 50,
51, Fig. D) stays on:
• Full water tanks warning light (green) (49, Fig. D)
• Full water sub-tank warning light (yellow) (50, Fig. D)
• Empty water tanks warning light (red) (51, Fig. D). When this warning light turns on, the pumps stop automatically.
29. 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.
