When the brushes are set a forward angle, the rear of the brush does not touch the surface. This
brings the rubbish in front of the suction mouth so that it does not revolve with the brush.
The sideways angle is adjusted to the shape of the surface or the degree of brush wear. Some
vehicle models are equipped with a hydraulic sideways adjustment which can be operated from the
cabin.
If the sideways angle is too large, it will create space between the brush and the
suction mouth, leaving a line of rubbish behind. This effect increases with increased
brush wear.
Figure 24:
1)
Unscrew the 2 nuts "A" of the brush
suspension.
2)
Set the forward angle:
-
Turn bolts ‘B’
to the right to
increase
the forward angle.
-
Turn bolts ‘B’
to the left to
decrease
the forward angle.
3)
Set the sideways angle:
-

the sideways angle to the surface.
4)
Once the correct setting has been
obtained, tighten the 2 nuts ‘A’.

Adjusting the brush pressure
The correct setting for the brush pressure among other things
depends on the type of litter, the surface, the brush wear and
the driving speed. Taking into account these circumstances
an acceptable brush pressure must be selected.
