SCRUBBING COMPONENTS
Scrub Brushes
This machine is equipped with two cylindrical scrub brushes.
These brushes scrub the fl oor and also sweep debris into
the debris hopper. These brushes should be checked daily
for wear and damage as well as entangled string, plastic, or
wire.
It is important for optimum debris pick up that the brushes be
installed with the V-shaped bristle patterns pointing toward
each other when viewed from above as shown.
When installing the brushes insert the drive hub end of the
brush into the scrub head. This automatically ensures that
the brush V-shaped pattern is positioned correctly.
To increase brush life these scrub brushes can be rotated
front-to-rear.
The brushes should be replaced when the bristle length
wears to .50 in (1,3 cm) in length.
Note:
Always replace the cylindrical scrub brushes in sets to
prevent poor scrubbing effi ciency.
