• Drive the machine on a level ground.
• While keeping the machine stationary, fully lower the side brooms and allow them to rotate for a few seconds.
• Stop and lift the side brooms, then move the machine.
• Check that the size and orientation of the prints left by the side brooms are as follows:
– The right side broom must touch the ground along a circle arc ranging from "11 o'clock" position to "4 o'clock" position
(1, Fig. AJ).
– The left side broom must touch the ground along a circle arc ranging from "8 o'clock" position to "1 o'clock" position (2,
Fig. AJ).
• Adjust the broom height when the prints are out of specifi cation, according to the following procedure.
2. Engage the parking brake with the lever (13, Fig. E).
3. Turn the ignition key (24, Fig. D) to OFF position and remove it.

brooms. To have a optimum adjustment, the arms must be slightly tensioned outwards.
