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 height as shown below:
• Drive the machine on a level ground.
• Engage the parking brake.
• Lower the main broom with the One-Touch push-button
(52).
• Start broom rotation by pressing the One-Touch push-
button (52) again and holding it down for 3 seconds.
• After 30 seconds of broom operation (visible on the
display, as per Figure 7), raise it by pressing the One-
Touch push-button (52).
• Check that the main broom print (A, Fig. 8), along its
length, is 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 (B, Fig. 9) as shown below:
• To increase the print width, turn the knob counter-
clockwise.
• To decrease the print width, lift the main broom with the
One-Touch push-button (52) 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 icon (71-N) appears on the display, change the
broom as described in the next paragraph.
NOTE
If it is not possible to adjust the print (A, Fig. 8)
properly, because the pressure on the floor at the
ends of the broom is different, refer to the Service
Manual.
