7. If the hopper may contain a lot of water, it is possible to drain it before lifting and dumping the hopper according to the following
procedure:
• Engage the parking brake with the lever (13, Fig. E) and get out of the machine.
• Open the left upper door (9, Fig. G) by disengaging the relevant fasteners (10).
• Disengage the hose (26, Fig. F) and drain the water from the hopper.
• Install the hose (26, Fig. F).
• Open the left upper door (9, Fig. G) by disengaging the relevant fasteners (10).
8. Loosen the side knobs (1, Fig. O) and open the rear shoote by turning it from the position (2) to the position (3).
9. Start the engine as shown in the relevant paragraph.
10. Carefully lift the hopper (6, Fig. G), by pressing the push-button (43, Fig. D) and the safety push-button (45).
11. If necessary, increase the engine speed with the accelerator lever (16, Fig. E), until the hopper starts lifting. The engine speed
which allows for hopper lifting is above 1,600 rpm depending on the load.
CAUTION!
The hopper lifting is delayed, so the push-button must be pressed and hold for a few seconds before the hopper
starts to lift.
CAUTION!
The hopper lifts only when the machine is fully stopped, the operator is on the driver's seat, the brooms are
stopped and the drive pedal is not pressed (neutral position). When lifting the hopper a buzzer sounds.
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. If the machine speed exceeds 5 km/h with the hopper lifted, the warning light (3, Fig. D) fl ashes
to warn about the dangerous manoeuvre.
WARNING!
If the machine is prefi t with snow equipment, ensure that the switches (51 and 52, Fig. D) are not pressed,
because this will prevent the hopper lifting/dumping.
12. Open the hopper door (44, Fig. G) with the switch (21, Fig. D); keep the switch pressed until the door is totally opened.
CAUTION!
The hopper door opens only when the machine is stopped.
13. Carefully dump the hopper (6, Fig. G), by pressing the push-button (40, Fig. D) and the safety push-button (45). Empty the
hopper.
14. When the dumping is completed, return the hopper to the horizontal position, by pressing the push-button (39, Fig. D) and the
safety push-button (45).
15. Lower the hopper (6, Fig. G) completely, by pressing the push-button (44, Fig. D) and the safety push-button (45). Keep the
push-buttons pressed, until the warning light (3) turns off.
CAUTION!
When lowering the hopper a buzzer sounds.
16. If necessary, check for hopper metal fi lter clogging, according to the following procedure:
• Engage the parking brake and turn off the engine.
• Lift the hopper door manually and secure it with the support rod (17, Fig. F).
• As shown in the Maintenance chapter, remove the fi lters (15 and 12, 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 (17, Fig. F) and place it in its housing.
17. Start the engine and close the hopper door (44, Fig. G) with the switch (21, Fig. D); keep the switch pressed until the warning
light turns off.
18. The machine is ready to start working again.
