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 weekly. The pattern
should be 50 to 75 mm (2 to 3 in) wide with the
main brush in the lowered position.
Rotate the main brush end-for-end after every 50
hours of operation for maximum brush life and
best sweeping performance.
Sweeping performance often becomes less
effective as the bristle length is worn. Replace the
main brush when the remaining bristles measure
between 40 mm (1--1/2 in) and 50 mm (2 in) in
length.
REPLACING MAIN BRUSH
1. Stop the machine, set the parking brake and
turn the machine power off.
FOR SAFETY: Before leaving or
servicing machine, stop on level
surface, set parking brake, turn off
machine, and remove key.
2. Open the left side main brush access door.
3. Loosen the idler arm mounting knob and
three other side skirt mounting knobs.
Remove the brush idler arm assembly.
