SUCTION INLET AND SKIRT HEIGHT AND OPERATION CHECK
Preliminary operations
Engage the parking brake (7, Fig. E).
Lift the suction inlet (10, Fig. G) according to the procedure shown in the relevant paragraph.
Turn off the engine, by turning the ignition key (17, Fig. D) counterclockwise, to the end of stroke, then remove it.
Suction inlet wheel check
Check that the three wheels (1, Fig. Z) of the suction inlet are in good conditions and turn freely (they must not be bent/
misshapen because of bumps or excessive pressure, etc.). Check also that the rubber thickness (2) is not lower than some
millimetre.
If necessary replace the wheels (1) (see the procedure in the Service Manual).
Sliding panel check
Check that the main sliding panel (3, Fig. Z), the front sliding panels (4) and (5), and the rear sliding panel (6) are in good
conditions and that their thickness (7) is not lower than 5 mm, otherwise replace them (see the procedure in the Service
Manual).
It is important to replace the sliding panels (3), (4), (5) and (6) when they are not completely worn, to avoid damaging the
relevant mounting screws and making them diffi cult to remove.
Replace the sliding panels (3), (4), (5) and (6) as a unit, to avoid steps in the union areas (8), caused by different levels of
wear.
Suction inlet skirt and wheel adjustment check
Check that the skirt (9, Fig. Z) is integral and that it does not have excessive tears (10) or lacerations (11), which can affect the
suction inlet operation.
If necessary replace the skirt (9) (see the procedure in the Service Manual).
Drive the machine on a level ground and lower the suction inlet (10, Fig. G) according to the procedure shown in the relevant
paragraph.
Turn off the engine, by turning the ignition key (17, Fig. D) counterclockwise, to the end of stroke, then remove it.
Check that the distance (12, Fig. Z) of the skirt from the ground is not bigger than 1 cm. Greater distances can affect the
suction inlet operation.
If necessary replace the skirt (9) (see the procedure in the Service Manual).
Also check that, when the wheels (1, Fig. Z) contact the ground, the sliding panels (3), (4), (5) and (6) do not touch the ground.
Otherwise the wheels (1) must be replaced to avoid an excessive wear of the sliding panels (see the procedure in the Service
Manual).
Start the machine according to the procedure shown in the relevant paragraph, then lift the skirt (9, Fig. Z) and check that it lifts
freely. Check that it lifts also when a force of some kg is applied (simulating to move bottles or other heavy objects that must
then be collected). If necessary, adjust the opening force of the skirt (9) according to the following procedure:
Turn off the machine.
Remove the screws and the right panel (20, Fig. E) in the cab.
Loosen the control valve locknut (1, Fig. Y) and turn the screw (2) as necessary, reminding that:
The opening force decreases by loosening the screw;
The opening force increases by tightening the screw.
When the adjustment is completed, tighten the locknut (1).
Install the right panel (20, Fig. E) in the cab and tighten the screws.
Assemble the components in the reverse order of disassembly.
