MAIN BROOM HEIGHT CHECK AND ADJUSTMENT
NOTE
Brooms with harder or softer bristles are available. This procedure is applicable to all types of brooms.
Check
Check that the main broom is at the correct distance from the ground, according to the following procedure:
Drive the machine on a level ground.
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), along its length, is 0.8-1.2 in (2-4 cm) wide.
If the print (A) is not within specifications, adjust the broom height according to the following procedure.
CAUTION!
If the main broom print is excessive (larger than 1.57 in (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.
Adjustment
Drive the machine on a solid and level ground and engage the parking brake with the lever (23).
Turn the ignition key (2) to “0”.
Loosen the knobs (B) on both sides of the machine.
On both sides of the machine, unscrew the knobs (B) and move the broom height variation indicator (C) as necessary, then
screw down the knobs (B).
The indicator (C) must be in the same position on both sides of the machine; the maximum difference allowed to obtain the
print (A) shown in step 1 (0.78 – 1.57 in (2 - 4 cm) wide) is two notches.
Perform step 1 again to check that the main broom is at the correct distance from the ground.
When the broom is too worn and can no longer be adjusted, replace it according to the procedure shown in the following
paragraph.
