SIDE BROOM HEIGHT 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. AK).
– 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. AK).
Adjust the broom height when the prints are out of specifi cation, 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. AL) 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.
Side broom forward tilting angle (5, Fig. AL) adjustment
6. On both sides of the machine, loosen the locknuts (6 and 7, Fig. AL), then adjust the forward tilting angle (5) by placing a lever
in the hole (9) and turning the tie rod (8).
When the adjustment is completed, tighten the locknuts (6) and (7).
7. Perform step 1 again.
Side broom side tilting angle (10, Fig. AL) adjustment
8. On both sides of the machine, loosen the screws (11 and 12, Fig. AL), then adjust the side tilting angle (10). When the
adjustment is completed, tighten the screws (11) and (12).
9. Perform step 1 again.
Side broom side position adjustment
10. The purpose of this adjustment is to improve the side position of the brooms as to the suction inlet (17, Fig. G).
11. To perform the adjustment, loosen/tighten the self-locking nuts (1 and/or 2, Fig. AM), thus changing the side position of the
brooms. To have a optimum adjustment, the arms must be slightly tensioned outwards.
12. When the side brooms are too worn out, the adjustment is not possible; replace the brooms according to the instructions in the
relevant paragraph.
