position
77dB(A)
MACHINE INSPECTION
•After the machine is unpacked, remember to recycle
all packing materials.
•Inspect the machine for damage or missing
components. If damage is found, contact the local
freight company to file a freight claim.
•Note: this machine is shipped with antifreeze in the
solution line system to protect the pump and valves
from freezing during transport and storage. Before
you use the machine, rinse the solution line system
with clean water (See Preparing the Machine).
MACHINE COMPONENTS
Solution Tank
The solution tank is the lower part of the machine
body. It has a capacity of 12 Gallons (45 liters).
Recovery Pails
The (2) recovery pails are the upper part of the
machine body. The pails each have a capacity of 6
gallons (23 liters).
Control Panel
The operator control panel is located on the handle of
the machine. This panel has components that control
various machine functions:
•The left rocker switch turns the vacuum motor on
and off.
•The right rocker switch turns the brush motor on and
off.
•The middle rocker switch controls the pump.
•The carpet spray switch (located below the left grip
handle) allows the liquid to be sprayed onto the
carpet. Press and hold the switch to start spraying
the liquid, release the switch to stop.
•The circuit breaker on the right side of the handle
protects the brush motor.
Cleaning Solution Flow Rate Valve
This machine has a two position valve located on the
lower rear panel that will allow the operator to use less
cleaning chemical for light duty applications.
•The low flow position provides a 38% reduction in the
cleaning solution consumption.
•The high flow position provides full capacity solution
application.
Brush Head Assembly
This machine has a floating brush head assembly that
adapts to the different carpet pile heights. The brush
head is offset to the right side of the machine to clean
against the wall.
•The brush head assembly includes the Spray Bar.
•Two brass spray jets provide a cleaning pattern over
the full width of the brush head.
Vacuum Shoe
The 16” (41 cm) wide vacuum shoe is located at the
front of the machine. As the machine moves backward
the vacuum shoe pulls the liquid out of the carpet.
Accessory hose option
•Remove the 2” hose adapter connection from the
machine.
•Attach the 1 ½” hose assembly with adapter plate to
the vacuum lid inlet.
•Pull back female quick disconnect sleeve on the
hose and convert to the male plug on the back of the
machine.
PREPARING THE MACHINE
Preparing the Solution and Recovery tanks:
•Never use water over 140°F (60°C).
•Before initial use, purge the antifreeze used for
shipping from the solution line system using clean
water only. Flush the system out completely.
•Excessively hot water will damage components such
as the pump, valves, and seals. Observe the carpet
manufacturer’s cleaning instructions.
•Make sure the solution indicator tube is securely
clipped in the upright position to keep fluids from
draining out.
•Put 1 to 2 gallons (4 to 8 liters) of water in the
solution tank first to help dilute the chemicals and
prevent excess sudsing. Dilute the cleaning
chemicals according to the manufacturer’s
instructions.
•Fill the tank by pouring the water and cleaning
chemicals through the mesh filter that covers the
opening at the front of the solution tank.
•Ensure Recovery pails are in position.
•Always use a defoamer in the Recovery pails to
protect the vacuum motor of this machine.
•Every time the solution tank is filled, add 2 to 3
ounces (60 to 90 milliliters) of defoamer to each
Recovery pail.
•Make sure the vacuum lid fits securely to the
recovery pails for an air-tight seal. The vacuum
motor will pull the lid down (creating suction) during
use.
Connect the Power Cord
This machine is equipped with a twist lock power cord.
•Align the three electrical contacts, push the contacts
together and turn one of the plugs 1/8 of a turn to
lock the two plugs in place. This will prevent the
machine from disconnecting during use.
Brush motor circuit breaker
If the brush becomes over loaded by deep pile carpet,
hair, strings or an obstruction the motor will draw too
much current and the circuit breaker will trip.

MACHINE OPERATION
This machine is very maneuverable and is designed
to clean as you pull backwards across the carpet.
When moving forward, always push down on the
handle to raise the front of the machine up and move
on all four wheels.
Normal Cleaning
•Always vacuum the carpet with a vacuum cleaner
before extraction.
•We recommend you wear clean tennis shoes or
non-slip shoes when working with a carpet
extractor. Street shoes or rubber cushion soled
shoes when wet will release absorbed dirt or
grease onto the wet carpet and cause re-soiling.
•You may need to pre-treat spots and heavy traffic
lanes before extraction. Refer to the “Common
Stains and Cleaning Treatments” chart for
examples of types of stains and the solution used
to treat the stain.
•Soak up excess liquids with a towel.
•Test cleaner on a small inconspicuous area to
make sure it will not damage the carpet fibers.
•Apply appropriate spotter, following directions on
the container.
•You may apply the pre-treat chemicals in a number
of ways:
•Use a hand held spray bottle.
•Use a 2 - 3 gallon (7 - 8 liter) pump up container
with a spray wand.
•Use the machine spray bar, by tilting the machine
backwards slightly away from the carpet. Press
and hold the carpet spray switch (located below
the left handle grip) to apply the chemical.
•Plug the machine into an appropriate wall outlet.
•Turn on the Vacuum, Pump, and Brush switches.
•Extract the perimeter of the room first, move the
vacuum shoe as close to the wall or baseboard as
possible. Use the right side of the machine to
clean against the wall for best results.
•Start on one side of the room and work your way
across the room in rows, always working away
from the cord.
•Lift up on the handle grips to ensure that the
vacuum shoe rests on the carpet.
•Press and hold the carpet spray switch to start
spraying and begin moving backwards. About 6"
(15 cm) before your stopping point, release the
carpet spray switch to stop spraying, and continue
moving backwards to recover all of the solution you
have just applied. This will prevent leaving an
excessively wet spot in the carpet. Move machine
forward on all four wheels to start the next path,
overlap 2” (5 cm) for best results. Continue
cleaning the entire area in this method.
•Monitor the solution level using the solution
indicator tube on the back left of the machine.
NOTE: If dirty solution does not appear through the
vacuum lid, check:
The vacuum lid is properly seated on the
recovery pails.
The machine’s vacuum shoe is touching the
carpet in working mode.
The solution tank is not empty.
NOTE: If foam appears on the vacuum lid, turn the
Vacuum switch off immediately and add more
defoamer to the recovery pails to dissolve the foam
or empty the recovery pails.
•As you clean, keep an eye on the liquid level in the
recovery pails. Empty the recovery pails as
needed during operation.
•When the solution tank runs empty, turn off the
vacuum, pump, and brush switches. Empty the
recovery pails and rinse thoroughly. Repeat the
procedures on Preparing the Machine as required.
Do not apply water more than twice in one area to
prevent excess wetting.
•Over-wetting can damage the carpet and the
underlying floor.
•If the brush becomes over loaded by deep pile
carpet, hair, strings, or an obstruction the motor will
draw too much current and the circuit breaker will
trip.
•Unplug the machine, check for debris, and remove
it.
•Push down on the circuit breaker to reset it and
resume operation.
SPECIAL CLEANING
This machine may be used to perform special
cleaning jobs other than “normal” scrubbing.
Double Scrubbing
This procedure provides deeper cleaning on heavily
soiled floors.
•Double scrub by making a second pass over the
carpet with only the brush turned on. Then, make
a third pass with the solution pump, vacuum and
brush on to remove the most dirt. Make an
additional vacuum pass to dry the carpet as much
as possible.
•The slower the cleaning pass, the more dwell time,
increasing the amount of dirt that is removed from
the carpet.

OPTION - ACCESSORY CLEANING
Preparing the Accessories:
•Select the correct tool for the job to be performed.
•Connect the solution hose to the quick connect at
the back, lower left side of the machine and on the
tool.
•To connect a tool, pull back on the collar of the
quick connect, insert one end of the solution hose
fitting and push it in until it locks. Attach the other
end of the solution hose to the tool in the same
manner.
•Remove the machine hose from the right side of
the vacuum lid and insert one end of the recovery
hose into the lid. Attach the other end of the hose
to the accessory tool.
Cleaning upholstery, stairs or confined areas:
•Prepare the solution / recovery tanks as you would
for normal carpet cleaning.
•To begin cleaning, turn on the rocker switch for the
solution pump and vac motor only. When you
squeeze the trigger of the accessory tool it will
spray the cleaning solution, release the trigger to
stop the spray.
•Do not apply water more than twice in one area
to prevent excess wetting.
•Over-wetting can damage upholstery and / or
fabric.
Priming the Solution Pump
During normal use the clean solution tank may run
dry. This will allow air to enter the pump and solution
lines. Air in the solution lines will prevent the pump
from working properly, you must prime the pump.
•Refill the solution tank.
•Disconnect any accessory tool that may be in use.
CAUTION - place machine near a floor drain prior to
the next step.
•Turn on the solution pump switch.
•Depress the center pin in the accessory quick
connect for 60 - 90 seconds (minimum). The pump
will spray air and solution out until all of the air has
been forced from the solution lines. When all of the
air has been expelled you may resume your
cleaning operation.
NOTE: The solution pump will not prime through the
spray jets or an accessory tool.

MACHINE MAINTENANCE
Routine maintenance is critical to ensure proper
machine operation and cleaning performance.
Perform all maintenance procedures as follows.
Always turn OFF all machine switches before
performing any maintenance.
DAILY MAINTENANCE
At the end of the day empty all liquids from both the
solution and recovery tanks. Rinse both tanks with
clean water to prevent chemical residue build up,
allow to air dry to prevent orders.
•Coil power cord onto the cord wrap.
•Remove dirt and/or lint build-up inside the vacuum
lid filter screen.
•Clean the solution line filter.
•Wash the vacuum lid with a soap solution to
prevent dirt from accumulating on the surface. To
avoid scratching, use of a soft cloth is
recommended.
•The solution tank can be emptied by: spraying the
liquid out through the spray bar, or using the
solution indicator tube.
•To use the solution indicator tube, unclip from the
machine handle and place the end into a recovery
pail.
•The recovery pails are emptied by lifting up the
vacuum lid and removing the pails from the
machine by using their handles. Drain the liquids
according to your local EPA regulations.
•Rinse the solution tank clean of all debris.
•Store in a dry area.
•Lean the machine back on all four wheels during
