SCRUB HEAD
The scrub head encloses the scrub brushes and a
solution dispensing system. The scrub head is
located directly behind the sweeping brush
compartment.
The scrub head is factory adjusted and the
measurement should not be changed unless
scrub head parts are damaged or are replaced.
BRUSHES
MAIN SWEEP BRUSH
The main sweep 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 sweep brush pattern daily. The
pattern should be 50 to 65 mm (2.0 to 3.0 in) wide
with the main sweep brush in the lowered
position. Adjust the main sweep brush pattern by
turning the main brush pressure knob located to
the left of the steering wheel, at the top of the
instrument panel.
Rotate the main brush end-for-end 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 sweep brush when the remaining bristles
measure between 40 mm (1
1
/
2
in) and
50 mm (2 in) in length.
