Adjusting the brush angle
The brushes can be set at a forward and sideways angle in relation to the surface that has to be
swept. The correct setting depends on several circumstances such as the condition of the litter,
the surface or the brush wear.
When the brushes are set at 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 that 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 31:
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:
-
Tilt the brush by hand to adjust the sideways
angle to the surface.
4)
Once the correct setting has been obtained, tighten
the 2 nuts ‘A’.
9.2.3.
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.
The brush pressure is regulated hydraulically. For this purpose operate the following two
switches on the central cab switchboard (fig. 6):
•
Switch 11
: pressure adjustment left-hand brush
•
Switch 12
: pressure adjustment right-hand brush
Excessive brush pressure results in increased brush wear
