SIDE BRUSH
The side brush sweeps debris along edges into
the path of the main brush.
Check the brush daily for wear or damage.
Remove any string or wire found tangled on the
side brush or side brush drive hub.
Check the side brush pattern daily. One-half of the
side brush bristles should contact the floor when
the brush is in motion. Adjust the side brush
pattern by the side brush down pressure knob.
Turn the knob counter-clockwise to increase the
brush contact with the sweeping surface, and
clockwise to decrease the brush contact with the
sweeping surface.
The side brush should be replaced when it no
longer sweeps effectively for your application. A
guideline length is when the remaining bristles
measure 50 mm (2 in) in length. You may change
the side brush sooner if you are sweeping light
litter, or wear the bristles shorter if you are
sweeping heavy debris.
REPLACING SIDE BRUSH
