MAIN BROOM HEIGHT CHECK

NOTE:
Brooms with harder or softer bristles are
available. This procedure is applicable for
all types of brooms.
1. Check the correct main broom height from the
ground (not carpet), proceeding as follows:
a. With the machine on level ground, keep the
machine stationary and allow the main broom
to rotate for several seconds.
b. Stop the main broom and move the machine.
c. Check that the main broom pattern (1, Fig. D),
proper width, is from 2 to 4 cm(0.8-1.6 in) on
the type of surface where the machine will be
used.
d. If the pattern (A) is different, it is necessary to
adjust the broom height, proceeding as de-
scribed in step 2.
2. With the machine on level ground, activate the
brake pedal (26, Fig. C) (if equipped), or block the
wheels
3. Turn the ignition key (2, Fig. B) to the "0" position.
4. Loosen the knobs (1, Fig. E) on both side of the
machine.
5. Using the knobs (1, fig. E) on both sides of the ma-
chine, rotate the broom height adjuster indicator
(2) as necessary and then retighten the knobs (1).
NOTE:
The indicator (2) does not have to be at the
same position on both sides of the ma-
chine; the maximum difference allowed is
2 notches to obtain a correct broom pat-
tern (1, Fig. D) from 2 to 4 cm (0.8 – 1.6 in)
as described in step 1.
6. Perform step 1 again to check the proper adjust-
ment of the main broom height from ground.
7. When the broom becomes too worn, adjustment is
no longer possible. Replace the broom following
the instructions in the following chapter.
CAUTION!
A main broom pattern in excess of 4 cm
(1.6 in) compromise the normal function
of the machine and can overheat the elec-
trical components, drastically reducing
their life.
Pay particular attention when checking
the main broom height (broom pattern)
and never operate the machine outside
the specifications listed above.

CAUTION!
It is advisable to use protective gloves
when replacing the main or side broom
because there can be potentially harmful
debris between the bristles.

els.
2. Turn the ignition key (2, Fig. B) to the "0" position.
3. Loosen the knobs (1, Fig. E) on both sides of the
machine.
4. Move the broom height adjuster indicators (2, Fig.
E) until the broom reaches the maximum distance
from the ground. Retighten the knobs (1).
5. Open the cover (7, Fig. C).
6. On the left side of the machine, remove the knob

9. Check that both broom hubs are free of dirt and fo-
reign materials (cords, rope, etc.) accidentally rol-
led up.
10. The new broom must be installed with the curve of
the bristle rows as shown in figure H (top view).
11. Slide the new broom into the broom housing and
align the main broom hub (1, Fig. I) with the drive
hub (4, Fig. Q).
