ADJUSTING THE CENTRAL BROOM AND THE SIDE BROOM:
CENTRAL BROOM:
If you notice that the machine no longer cleans perfectly or leaves dirt behind, you will need to adjust the central broom. To adjust its
height, unscrew the ring nut Detail 4 Fig. 15, adjust the knob Detail 3 Fig. 15 until reaching the desired height and tighten the ring nut Detail
4 Fig. 15 to fasten the knob.
N.B.:
To make sure that the central broom is adjusted properly, measure its "track" as follows:
Once the adjustments have been made, start the machine and, without travelling forwards or in reverse, leave it on the spot for at least
10/15 sec. with the central broom lowered.
Turn the engine off, raise the central broom and make the machine move forwards, until you can see a track left by the rotation of the
central broom on the floor, as shown in Fig. 16.
SIDE BROOM:
To adjust the height of the side broom, unscrew the ring nut Detail 1 Fig. 15, adjust the knob Detail 2 Fig. 15 until reaching the desired
height and tighten the ring nut Detail 1 Fig. 15 to fasten the knob.
