the machine parking brake.

the main brush. Allow the brush to rotate in
one place for 2 minutes at the NORMAL
main broom pressure setting.
3. Press the
sweep switch
again to raise and
stop the main brush.
4. Drive the machine off the test area.
5. Observe the width of the brush pattern. The

CABLES TO RAISE THE BRUSH.
LOWER THE BRUSH ONLY.
6. If there is a taper in the pattern, adjust the
lift cables to increase the width of the narrow

have equal tension on both sides of the
machine.
