MAINTENANCE / SERVICE
Adjusting The Brush Pressure
WARNING:
Adjusting the brush too low can damage the brush motor
and lessen the cleaning performance.
As the scrub
brush wears,
your brush
pressure on the
floor will de-
crease. To com-
pensate for
brush wear,
adjust the
wheels to lower
the brush head.
To adjust the
brush pressure, tip the machine on its back.
Insert a 5/32 Allen wrench into the wheel block windows. Turn the Al-
len wrench counterclockwise one complete turn. Adjust both wheels by
the same amount.
IMPORTANT: You must adjust each wheel by the same amount. Failure to
do so will cause un-even brush wear. If you don’t know if the wheels have both
been evenly adjusted, turn the screw as far as you can clockwise, then begin
again to adjust each wheel counterclockwise by the same amount. It is wise,
with each full turn of the screw, to stand the machine back up and check the
brush deflection from the side of the machine.
We recommend one inch of
brush width touch the floor but only a 1/4 inch of brush depth on the
floor.
