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, according
to the following procedure:
• Drive the machine on a level ground.
• Engage the parking brake.
• Lower the main broom and turn it pressing the
accelerator pedal for approx. one minute. Do not
operate the broom continuously in order not to overheat
the drive motor braked.
• Stop and lift the main broom, then move the machine
and switch it off.
• Check that the main broom print (A, Fig. 6), along its
length, is 0.8 to 1.6 in (2 to 4 cm) wide.
If the print (A) is not within specifications, adjust the main
broom height according to the following procedure.
2. Turn the knob (A, Fig. 7) as shown below:
• to increase the print length, turn the knob counter-
clockwise;
• to decrease the print length lift the broom with the lever
(63) and then turn the knob clockwise.
NOTE
The knob can be used both to adjust the print and to
adjust the broom according to the bristle wear.
3. Perform step 1 again to check that the main broom is at the
correct distance from the ground.
4. When the broom is too worn to be adjusted, replace it as
shown in the next paragraph.
NOTE
If it is not possible to adjust the print (A, Fig. 6)
properly, because the pressure on the floor at the
ends of the broom is different, refer to the Service
Manual.
