CHECK
1. Check the main broom for proper ground clearance,
proceeding as follows:
– Drive the machine on a level ground;
– Keep the machine stationary and rotate the
main broom for a few seconds;
– Stop and lift the main broom, then move the
machine;
– Check that the main broom print (1, Fig. D),
along its length, is from 2 to 4 cm wide.

ground, it must be unscrewed.
Screw the locknut (2, Fig. E).
