Suction inlet skirt, baffle plate and wheel adjustment check

6.Check that the skirt (8, Fig. AC) and baffle plate (9) are integral and that they do not have excessive tears (10) or lacerations (11), which can affect the suction inlet operation.

If necessary replace the skirt (8) and the baffle plate (9) (see the procedure in the Service Manual).

7.Drive the machine on a level ground and lower the suction inlet (17, Fig. G) according to the procedure shown in the relevant paragraph.

8.Turn off the engine, by turning the ignition key (24, Fig. D) counterclockwise, to the end of stroke, then remove it.

9.Check that the distance (12, Fig. AC) of the skirt from the ground is not bigger than 0.4 in (1 cm). Greater distances can affect the suction inlet operation.

If necessary replace the skirt (8) (see the procedure in the Service Manual).

10.Check that all the wheels (1, Fig. AC) contact the ground.

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. AD) until the rear wheel reaches the correct position.

11.Also check that, when the three wheels (1, Fig. AC) contact the ground, the sliding panels (3), (4), (5) do not touch the ground, otherwise the wheels (1) must be replaced to avoid an excessive wear of the sliding panels (for wheel replacement procedure, see the Service Manual).

12.The adjuster (2, Fig. AD) is used to balance the suction inlet when it is lifted.

13.Start the machine according to the procedure shown in the relevant paragraph, then lift the skirt (8, Fig. AC) 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 (8) according to the following procedure:

•Turn off the machine.

•Loosen the control valve locknut (13, Fig. AC) 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. AC).

14.Assemble the components in the reverse order of disassembly.

SIDE BROOM POSITION CHECK AND ADJUSTMENT

NOTE

Brooms of various hardness are available. This procedure is applicable to all types of brooms.

Check

1.Check the side brooms for proper height and tilting, according to the following procedure:

•Drive the machine on a level ground.

•While keeping the machine stationary, fully lower the side brooms and allow them to rotate for a few seconds.

•Stop and lift the side brooms, then move the machine.

•Check that the size and orientation of the prints left by the side brooms are as follows:

–The right side broom must touch the ground along a circle arc ranging from “11 o’clock” position to “4 o’clock” position (1, Fig. AE).

–The left side broom must touch the ground along a circle arc ranging from “8 o’clock” position to “1 o’clock” position (2,

Fig. AE).

Adjust the broom height when the prints are out of specification, according to the following procedure.

2.Engage the parking brake with the lever (13, Fig. E).

3.Turn off the engine, by turning the ignition key (24, Fig. D) counterclockwise, to the end of stroke, then remove it.

Side broom height adjustment

4.On both sides of the machine, operate on the tensioning self-locking nut (3, Fig. AF) of the spring (4) and consider the following:

•To lower the broom, the nut (3) must be unscrewed;

•To lift the broom, the nut (3) must be screwed.

5.Perform step 1 again.
