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, according to the following procedure:
– Drive the machine on a level ground.
– Keep the machine stationary and rotate the main
broom for a few seconds.
– Stop the main broom, then move the machine and
switch it off.
– Check that the main broom print (1, Fig. D), along its
length, is 2 to 4 cm wide.
If the print (1) is not within specifications, it is necessary
to adjust the broom height, according to the procedure
shown 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 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
shown in step 1.
6.
Perform step 1 again to check that the main broom is at
the correct height from the ground.
7.
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.
Pay careful attention when performing the
above-mentioned checks, and always use the
machine according to the indicated conditions.
