SIDE BRUSH ADJUSTMENT
AND REPLACEMENT
When the side brush is fairly worn, its height
must be adjusted to recover as much of the
brush consumption as possible.
Lower the brush (motor on).
Please make sure that the ground contact area
is as shown in the figure.
Warning: these operations must be carried
out with the machine off, the key switched
off (for battery-operated version), selector
in "OFF" position (for petrol-operated ver-
sion) and with the machine on even floor.
If you need to change the ground contact area,
just slacken counternut "

Restart the brush and make sure that the
ground contact area is as required. If neces-
sary, just repeat the adjusting operation until
reaching the right position.
When the brush is remarkably worn out, it is
necessary to replace it. Just press the two tabs
inwards and remove the brush.
Reinstall the new brush by carrying out the re-
verse operation and pushing it with your hands.
