SUCTION INLET AND SKIRT HEIGHT AND OPERATION CHECK
Preliminary operations
Engage the parking brake (13, Fig. E). 1.
Lift the suction inlet (17, Fig. G) according to the procedure shown in the relevant paragraph. 2.
Turn the ignition key (24, Fig. D) to OFF position and remove it. 3.
Suction inlet wheel check
Check that the three wheels (1, Fig. AH) of the suction inlet are in good conditions and turn freely (they must not be bent/ 4.
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. AH) and the front sliding panels (4) and (5) are in good conditions and that their 5.
thickness (6) is not lower than 0.2 in (5 mm), otherwise replace them (see the procedure in the Service Manual).
It is important to replace the sliding panels (3), (4), (5) when they are not completely worn, to avoid damaging the relevant
mounting screws and making them dif
fi cult to remove.
Replace the sliding panels (3), (4), (5) as a unit, to avoid steps in the union areas (7), caused by different levels of wear.
Suction inlet skirt, baf fl e plate and wheel adjustment check
Check that the skirt (8, Fig. AH) and baf fl e plate (9) are integral and that they do not have excessive tears (10) or lacerations 6.
(11), which can affect the suction inlet operation.
If necessary replace the skirt (8) and the baf
fl e plate (9) (see the procedure in the Service Manual).
Drive the machine on a level ground and lower the suction inlet (17, Fig. G) according to the procedure shown in the relevant 7.
paragraph.
Turn the ignition key (24, Fig. D) to OFF position and remove it.
8.
Check that the distance (12, Fig. AH) of the skirt from the ground is not bigger than 0.4 in (1 cm). Greater distances can affect 9.
the suction inlet operation.
If necessary replace the skirt (8) (see the procedure in the Service Manual).
Check that all the wheels (1, Fig. AH) contact the ground.
10.
If the rear wheel does not contact the ground, or if it contacts the ground with too much force, adjust its height according to the
following procedure:
On both sides of the suction inlet, unscrew/screw the self-locking nuts (1, Fig. AI) until the rear wheel reaches the correct •
position.
Also check that, when the three wheels (1, Fig. AH) contact the ground, the sliding panels (3), (4), (5) do not touch the ground, 11.
otherwise the wheels (1) must be replaced to avoid an excessive wear of the sliding panels (for wheel replacement procedure,
see the Service Manual).
The adjuster (2, Fig. AH) is used to balance the suction inlet when it is lifted.
12.
Start the machine according to the procedure shown in the relevant paragraph, then lift the skirt (8, Fig. AH) and check that 13.
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 (8) according to the following procedure:
Turn off the machine. •
Loosen the control valve locknut (13, Fig. AH) and turn the screw (14) 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 (13, Fig. AH).
•
Assemble the components in the reverse order of disassembly.
