5.5.1 Changing the side brush
Check the side brush (Fig. 8/1) weekly
and change in the case of wear.
1. Switch the machine off and lay it on
its side.
2. Remove the wing bolt (Fig. 8/2) with
the washer from underneath the side
brush (Fig. 8/1).
3. Pull the side brush off.
4. Position the new side brush on the
carrier(Fig. 8/3) and fix in place with
the wing bolt and washer.
5.5.2 Setting the sweeping pattern
In the case of brush wear, and after
changing the side brush (Fig. 8/1), re-
adjust the sweeping pattern.
1. Switch the machine off, unscrew the
locking bolt (Fig. 8/7) and open the
hood (Fig. 8/4).
2. Loosen the counternut (Fig. 8/6) and
adjust the sweeping pattern by turn-
ing the adjusting bolt (Fig. 8/5) clock-
wise and counterclockwise so that it
touches the floor.
3. Tighten the counternut again and
close the hood.
4. Switch the machine on and allow the
side brush to run while standing still

6. Check the sweeping pattern, com-
paring it with a clock viewed driving
forward. When set correctly, the
sweeping pattern must make an im-
