USING THE REAR SUCTION PIPE (*)

(*) Optional
To collect dust/debris with the rear suction pipe (optional) (43, Fig. G), rather than the suction inlet (17, Fig. G), perform the following
procedure.
1. Turn off the engine and engage the parking brake with the lever (13, Fig. E).
2. Loosen the suction pipe mounting knobs (1, Fig. P), then remove the suction hole cover (2) using the knob (3).
3. As shown in the Hopper Dumping paragraph, lift the hopper for 3.9-5.9 in (10-15 cm) approximately, then turn off the engine.
4. Open the right upper door (28, Fig. G) and remove the gasket (7, Fig. F).
5. With a suitable ladder, insert and secure the gasket (7, Fig. F) on the hopper suction hole (1, Fig. Q).
6. Lower the hopper completely, as shown in Hopper Dumping paragraph.
7. Release the fastener (42, Fig. G) of the rear suction pipe (43).
8. Open the support arm (45, Fig. G) and connect the chain (1, Fig. R) to the suction pipe to support it.
9. Open the dust control system nozzle valve (23, Fig. F).
10. Start the engine as shown in the relevant paragraph.
11. Check that the hopper (7, Fig. G) is lowered and that the warning light (3, Fig. D) is off.
12. 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
13. Turn on the suction fan with the lever (8, Fig. E).
14. 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 operator is on the driver's seat (14, Fig.
E) and the water pump switch (27, Fig. D) is pressed, allows for water supply to the nozzles only if the broom
rotation is enabled.
If the operator is not on the driver's seat (14, Fig. E) to use the rear pipe, water can be supplied by the nozzles
using the water pump switch (27, Fig. D) only.
15. Disengage the parking brake with the lever (13, Fig. E).
16. With the help of an assistant, start to collect debris with the rear suction pipe, by grasping it as shown in Figure S.
While working, the machine picks up both light materials such as dust, paper, leaves, etc. and heavy materials such as stones,
bottles, etc.
17. If necessary, open the valve (23, Fig. F) to supply water to the plastic pipe.
18. To restore the machine operation with the suction inlet (17, Fig. G), perform the steps 2 to 17 in the reverse order.
