HOPPER MANUAL LIFTING

To lift/lower the hopper (12, Fig. G) manually (when the diesel engine is faulty, etc.) perform the following procedure.
Hopper manual lifting
1. Check that the machine is on a solid and level ground, especially if the hopper (12, Fig. G) is full.
2. Turn off the engine, by turning the ignition key (17, Fig. D) counterclockwise, to the end of stroke, then remove it.
Remove the ignition key (17, Fig. D).

7. Turn the hopper lifting/lowering selector (3, Fig. L) to the lifting position (to lift the hopper turn the selector on the right, to lower
the hopper turn the selector on the left) and, if necessary, try to pump with the lever (1).
8. Carefully activate the pump (2, Fig. L) with the lever (1) and lift the hopper completely.
9. Remove the lifted hopper locking pins (9, Fig. F) from the housings (10), and place them into the holes (11).
Hopper manual lowering
10. Remove the two locking pins (9, Fig. F) from the holes (11) and place them into the housings (10).
11. Turn the selector (3, Fig. L) to the lowering position and activate the pump (2) with the lever (1) until the hopper is completely
lowered.
12. Turn the selector (3, Fig. L) to neutral position.
13. Remove the lever (1, Fig. L) from the pump and place it in its housing (29, Fig. F).
14. Close the right lid (16, Fig. G) by engaging the fasteners (17) with the supplied key.

LIFTED HOPPER LOCKING PIN INSTALLATION

Before working under the lifted hopper (1, Fig. F), it is necessary to install the locking pins (9) according to the following procedure.
WARNING!
For safety purposes, before working under the lifted hopper, it is necessary to install the locking pins (9, Fig. F).
This procedure is necessary even if the hopper lifting cylinders are equipped with parachute valves that prevent
the hopper from lowering accidentally in case of break/leakage from a pipe/fi tting on the hydraulic system.
Locking pin installation
1. Lift the hopper (12, Fig. G) completely according to the procedure shown in the relevant paragraph.
2. Turn off the engine with the ignition key (17, Fig. D) and engage the parking brake with the lever (7, Fig. E).
3. Remove the lifted hopper locking pins (9, Fig. F) from the housings (10), and place them into the holes (11).
Locking pin removal
4. If necessary, start the machine and slightly lift the hopper to release the locking pins.
5. Remove the two locking pins (9, Fig. F) from the holes (11) and place them into the housings (10).
6. Lower the hopper (12, Fig. G) completely according to the procedure shown in the relevant paragraph.
