F) max. Fill to the “DO NOT
FILL PAST THIS LINE” decal on the front of the
tank. If powdered cleaning chemicals are used,

4.
Turn the height adjustment knob to raise or lower
the brush to your carpet type as shown on the
height adjustment decal.
5.
Turn on the MASTER Switch.
6.
Position the machine at the first area to be
cleaned. Press and hold the CARPET CLEANING
button. This sprays solution on the carpet and
activates the brush. Pull the machine toward you
about 1.2 M (4 ft) while lifting the handle lightly to
form a tight vacuum seal on the carpet for best
water recovery.
WARNING: Flammable materials or reactive
metals can cause an explosion or fire. Do not pick
up.
NOTE: You can scrub stains with brush only and no
spray to prevent overwetting the carpet. Turn off the
MASTER switch and press the CARPET CLEANING
button.
7.
Release the CARPET CLEANING button to stop
spray, but continue to pull the machine toward you
for another foot. Then, push down on the handle
and roll the machine forward to the next strip,
overlapping about 48 mm (2 in).
NOTE: If the brush stops during carpet cleaning,
UNPLUG THE MACHINE, remove any clogging debris
wrapped around the brush, then push in the BRUSH
RESET Button located under the switchbox.
While cleaning, periodically check the recovery tank
for foam buildup. If foam does appear, pull the
vacuum hose out of the recovery dome, then pour
about 30 ml (2 Tbs) of defoamer into the dome
opening with the vacuum motor running to draw
defoamer into the tank.
ATTENTION: Foam or water will damage the
vacuum motor. Always prevent foam or water
from entering the standpipe screen by using
defoamer. Damage due to foam or water is NOT
COVERED BY WARRANTY.
8.
When the recovery tank is full, as shown by the
FULL LINE decal on the side of the recovery tank,
place a bucket under the drain valve downspout
and pull the T–handle to empty the dirty water.
Use a separate bucket for filling and emptying.
9.
When you have finished your cleaning job, drain
the recovery tank, then rinse it thoroughly to
prevent odor buildup inside the tank.
