5. Push the new or flipped brush into the scrub head.
6. Line up the two slots in brush end with the two
tabs on the brush plug on the drive end of the
scrub head. Make sure the brush pushes all the
way on the brush plug. If the brush does not
engage properly on the brush plug, the brush plate
will not mount to the machine.

brush by putting the tabs on the plug in the brush
slots. Place the brush plate knob in the brush plate
and mount the brush plate to the side of the scrub
head. Turn the brush plate knob to the right to
tighten it.
SOLUTION DISPENSING TUBE
The solution dispensing tube is located at the front and
on the inside of the scrub head. The small holes drilled
in the tube evenly dispense the cleaning solution over
the brush. The dispensing tube can be removed from
the scrub head for cleaning if required. Clean the tube
if the solution does not dispense evenly over the
brush.
CLEANING THE DISPENSING TUBE:
1. Unplug the machine. Disconnect the solution feed
hose from the quick disconnect by pulling back on
the knurled sleeve of the female disconnect until
the male fitting releases.
WARNING: Hazardous voltage. Shock or
electrocution can result. Unplug machine before
servicing.
