1.6 Setting the brush angle
This operation usually only requires to be carried out when the machine is installed. The requirement is to set
the angle of the brushes so that they sweep the debris into the central part of the machine, where the airflow
will pick it up. To do so, the brushes need to be tilted so as to touch the ground as shown on the following
picture:
a. Remove the plastic brush cover.
b. Loosen the top nut shown on the picture to adjust the roll angle
(usually 5 degrees).
c. Loosen the four screws shown on the picture to adjust the pitch angle.
The front two screws are located in slots.
Brushes do not
