MAIN BROOM HEIGHT CHECK

NOTE
Brooms of various hardness are available. This
procedure is applicable to all types of brooms.
1. Check the main broom for proper ground clearance,
proceeding as follows:
– Drive the machine on a level ground.
– Keep the machine stationary and rotate the main
broom for a few seconds.
– Stop the main broom and move the machine.
– Check that the main broom print (1, Fig. D), along
its length, is from 2 to 4 cm wide.
If the print (A) is different, it is necessary to adjust the
broom height, proceeding as described in step 2.
2. Drive the machine on a level ground and activate the
pedal brake (25, Fig. C) (if present).
3. Remove the key (2, Fig. B) from the machine on/off
switch.
4. Loosen the knobs (1, Fig. E) on both sides of the
machine.
5. Move the broom height variation indicator (2) as
necessary on both sides of the machine by using the
knobs (1, Fig. E), then screw down the knobs (1).
NOTE
The indicator (2) must be at the same position
on both sides of the machine; the maximum
difference allowed is 2 notches to obtain the
print (1, Fig. D) from 2 to 4 cm as described in
step 1.
6. Perform step 1 again to check the proper adjustment
of the main broom height from the ground.
7. When the broom is too worn to be adjusted, replace it
as shown in the next 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.
Take care when performing the
above-mentioned checks and use the
machine only according to the indicated
conditions.
