Begin cleaning by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Turn the Solu-
tion Switch
(B)
OFF prior to turns to ensure complete extraction of solution from carpet. Adjust when necessary the machine speed according to the condi-
tion of the carpet.
If there is little or no
fl
uid entering the recovery tank, the solution tank may be empty. Re
fi
ll the solution tank with water.

The recovery tank has an automatic
fl
oat shut-off
(27)
to prevent solution from entering the vacuum system when the recovery tank is full. When the
fl
oat
shut-off is activated, the control system will shut down the scrub, vacuum, solution and detergent systems. The Recovery Tank FULL Indicator
(E12)
will
display. To clear the display, cycle the Key Switch

fl
oat closes, the recovery tank must be emptied. The machine
will not
pick up water with
the
fl
oat closed.
NOTE:
If the control repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a quali-
fi
ed service technician refer to the service manual to perform this function.

. The solution pump, detergent pump and all
three solution solenoids will turn OFF immediately. The deck will raise to its upper limit and the brush motors will turn OFF. After a 3 second delay the
vacuum shoes will raise to the up position. Once the deck is raised, the vacuum motors will turn OFF after a 10 second delay.

Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose
(28)
from its rear storage
area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled
fl
ow of waste water). Re
fi
ll the solution
tank and continue cleaning.
NOTE:
Make sure the Recovery Tank Cover
(24)
and the Recovery Tank Drain Hose
(28)
cap are properly seated or the machine will not pick-up water correctly.
