SIDE BRUSH
The side brush sweeps debris from curbs or
gutters into the path of the main brush. The side
brush should be inspected daily for wear or
damage. Remove any string or wire found tangled
on the side brush or side brush drive hub.
The side brush pattern should be checked
periodically. One-third of the side brush bristles
should contact the floor when the brush is in
motion. The side brush pattern adjustment is
made by turning the side brush adjustment knob
on the front bumper.
The side brush should be replaced when the
remaining brush bristle measures 2.5 in (65 mm)
in length.
