BRUSHES
MAIN BRUSH
The main brush is tubular and spans the width of
the machine, sweeping debris into the debris
hopper. It should be inspected daily for wear or
damage. Remove any string or wire found tangled
on the main brush, main brush drive hub, or main
brush idler hub.
Rotate the main brush end-for-end after every 50
hours of operation for maximum brush life and
best sweeping performance.
The main brush pattern should be checked daily.
It should be 2 to 2.5 in (50 to 65 mm) wide with
the main brush in the (Main Brush Down) position.
Main brush pattern adjustments are made by
turning the height adjustment knob on the
instrument panel.
The main brush should be replaced when the
remaining bristles measure 1.25 in (30 mm) or
less in length.
