MAIN BROOM HEIGHT CHECK AND
ADJUSTMENT
NOTE
Brooms of various hardness are available.
This procedure is applicable to all types of
brooms.
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.

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.
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
following paragraph.
CAUTION!
An excessive print (larger than 4 cm) of the
main broom can lead to the machine
malfunction and the overheating of the
moving parts, thus reducing machine life.
Be extremely careful when performing the
above-mentioned checks and always use
the machine according to the indicated
conditions.
