MAIN BROOM HEIGHT CHECK AND
ADJUSTMENT
1.
Check that the main broom is at the correct height
from the ground, proceeding as follows:
– Drive the machine on a level ground.
– Keep the machine stationary and rotate the main
broom for a few seconds.
– Stop and lift the main broom, then move the
machine.
– Check that the main broom print (1, Fig. D), along
its length, is from 0.79 to 1.57 in (20 to 40 mm)
wide.
If the print (1) is not within specifications, it is
necessary to adjust the broom height, proceeding
as described in step 2.
2.
Drive the machine on a level ground and engage the
parking brake (6 and 7, Fig. C).
3.
Turn the ignition switch (2, Fig. B) to “0” position.
4.
Loosen the knobs (1, Fig. E) on both sides of the
machine.
5.
Operating on the knobs (1, Fig. E) move, on both
sides of the machine, the broom height variation
indicator (2) as necessary and then screw down the
knobs (1).
The indicator (2) must be in the same position on both
sides of the machine; the maximum difference
allowed to obtain the print (1, Fig. D) described in step
1 (0.79 to 1.57 in (20 to 40 mm) wide)) is 2 notches.
6.
Perform step 1 again to check that the main broom is
at the correct height from the ground.

When the broom is too worn and can no longer be
adjusted, replace it according to the instructions in the
