Brushes
FIG 8
FIG 9
The sweeper brushes are driven by hydraulic motors A and B (fig.8) on side and main brush for
'diesel sweeper'
Side brushes
The side brushes sweep dirt from the edges of floors and from corners, and direct it to the centre
of the sweeper where it can be picked up by the main brush.
The side brushes are floating . When they come into contact with unmovable objects (such as
pillars, walls, etc.) the brushes unit retracts, avoiding knocks. This ensures that the brushes are
not damaged.
Lifting and lowering the side brush
The side brush is lifted and lowered by lever A (fig.9). The side brush "floats".
Adjusting the side brushes
Check that the "T" shapes of the traces left by the side brushes are as shown in (fig.8).
As the bristles of the side brushes wear down, adjust the height of the brushes from the floor to
maintain these traces.
Proceed as follows to adjust the side brushes:
• Loosen the screw 1 (fig.9)
• Move in ahead of a notch the adjusting 2 (fig.9)
• Tighten the screw 1
Replacing the side brushes
Unscrew the four screws 3 (fig.10) and the brush comes away from its support.
After fitting the new brush, repeat the adjustment operations described, moving the stopper on
the slotted element in the opposite direction to that described for adjustment.
