MAIN BROOM HEIGHT CHECK AND ADJUSTMENT

NOTE
Brooms with harder or softer bristles are available. This procedure is applicable to all types of brooms.
1. Check the main broom distance from the ground as shown below:
• Drive the machine on a level fl oor.
Keep the machine stationary and turn on the main broom for a few seconds.
• Stop the main broom, then move the machine and turn it off.
• Check that the main broom print (A, Fig. 2), along its length, is 2 to 4 cm wide.
• If the print (A, Fig. 4) is not within specifi cations, adjust the broom height as shown in step 2.
2. Make sure that the machine cannot move independently; if equipped, press the pedal brake (26).
3. Turn the ignition key (61) to "0".
4. Loosen the knobs (A, Fig. 3) on both sides of the machine.
5. On both sides of the machine, loosen the knobs (A, Fig. 3) and move the main broom height variation indicator (B) as
necessary, then tighten the knobs (A).
NOTE
The indicator (B, Fig. 3) must be in the same position on both sides of the machine; the maximum difference allowed to
obtain the print (A, Fig. 2) shown in step 1 (2 - 4 cm wide) is two notches.
6. Perform step 1 again to check that the main broom is at the correct distance 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 (larger than 4 cm), the machine regular operation is affected and the moving
or electrical parts can overheat, thus reducing machine life.
Pay careful attention when performing the above-mentioned checks, and always use the machine according to
the indicated conditions.
