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 (26, Fig. C) (if present).
3. Turn the ignition key (2, Fig. B) to "0" position.
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!
If the main broom print is excessive (superior to 4 cm), the machine regular operation is affected and
the moving or electrical parts can overheat, thus reducing machine life.
Take care when performing the above-mentioned checks and use the machine only according to the
indicated conditions.
