BRUSHES
MAIN BRUSH
The main brush is cylindrical and spans the width
of the machine, sweeping debris into the hopper.
Check the brush daily for wear or damage.
Remove any string or wire tangled on the main
brush, main brush drive hub, or main brush idler
hub.
Check the main brush pattern daily. The pattern
should be 50 to 65 mm (2.0 to 2.5 in) wide with
the main brush in the Down position. Adjust the
main brush pattern by turning the main brush
pressure knob located next to the brush position
lever.
Rotate the main brush end-for-end every 50 hours
of operation for maximum brush life and best
sweeping performance.
Replace the main brush when the remaining
bristles measure 30 mm (1.25 in) in length.
