DUST AND DEBRIS COLLECTION SYSTEM
SUCTION INLET AND SKIRT HEIGHT AND OPERATION CHECK
Preliminary operations
Engage the parking brake with the lever (66).
Lift the suction inlet (12), according to the procedure shown in the User Manual.
Turn the ignition key (76) to OFF position and remove it.
Suction inlet wheel check
Check that the three wheels (A) 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 (B) is not lower than some millimeters.
If necessary replace the wheels (A) (see the procedure in relevant paragraph).
Sliding panel check
Check that the main sliding panel (C) and the front (D) and (E) and rear (H) sliding panels are in good conditions and that their
thickness (F) is not lower than 5 mm, otherwise replace them (see the procedure in the relevant paragraph).
It is important to replace the sliding panels (C), (D), (E), and (H) when they are not completely worn, to avoid damaging the
relevant mounting screws and making them diffi cult to remove.
Replace the sliding panels (C), (D), (E), and (H) as a unit, to avoid steps in the union areas (G), caused by different levels of
wear.
Suction inlet skirt and wheel adjustment check
Check that the skirt (I) is integral and that it does not have excessive tears (J) or lacerations (K), which can affect the suction
inlet operation.
If necessary replace the skirt (I) (see the procedure in the relevant paragraph).
Drive the machine on a level ground and lower the suction inlet (12) according to the procedure shown in the User manual.
Turn the ignition key (76) to OFF position and remove it.
Check that the distance (L) 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 (K) (see the procedure in the relevant paragraph).
Also check that, when the three wheels (A) contact the ground, the sliding panels (C), (D), (E), and (H) do not touch the
ground, otherwise the wheels (A) must be replaced to avoid an excessive wear of the sliding panels (for wheel replacement
procedure, see the relevant paragraph).
Start the machine according to the procedure shown in the User Manual, then press the switch (69) and check that the skirt
(I) 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 (I) according to the following procedure:
Turn off the machine.
Remove the screws and the right panel (22) in the cab.
Loosen the control valve locknut (N) and turn the screw (O) 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 (N).
Install the right panel (22) in the cab and tighten the screws.
Reset
Assemble the components in the reverse order of disassembly.
