MAIN BROOM HEIGHT CHECK AND
ADJUSTMENT
NOTE
Brooms with harder or softer bristles are available.
This procedure is applicable to all types of brooms.
1.
Check the main broom distance from the ground,
according to the following procedure:
•
Drive the machine on a level ground.
•
Keep the machine stationary, lower the main broom
and turn it on for a few seconds.
•
Stop and lift the main broom, then move the machine
and switch it off.
•
Check that the main broom print (A, Fig. 3), along its
length, is 2 to 4 cm wide.
If the print (A) is not within specifi cations, adjust the main
broom height according to the following procedure.
2.
Turn off the machine by turning the ignition key (68) to "0",
then remove it.
WARNING!
Before opening the left door (5), always turn
off the machine in order to stop belt and pulley
rotation.
3.
Remove the screw, then disengage the fastener (6).
4.
Open the left door (5).
5.
Loosen the locknut (B, Fig. 4).
6.
Turn the knob (A) and consider that:
•
To decrease the pressure of the broom on the ground,
it must be screwed
•
To increase the pressure of the broom on the ground, it
must be unscrewed
NOTE
To achieve the maximum pressure on the ground,
unscrew the knob completely.
7.
Tighten the locknut (B, Fig. 4).
8.
Perform step 1 again to check that the main broom is at
the correct distance from the ground.
9.
When the broom is too worn to be adjusted, replace it as
shown in the next paragraph.
10.
Close the left door (5) and engage the fastener (6), then
tighten the screw.
NOTE
If it is not possible to adjust the print (A, Fig. 3)
correctly, because the pressure on the ground at
the ends of the broom is different. For the relevant
adjustment procedure, refer to the Service Manual.
