HOW THE MACHINE WORKS
This machine is constructed to clean carpets.
The head, which pre–soaks the carpet and lifts the
dirt, contains solution dispensing nozzles .
The vacuum picks up the solution into the recovery
tank. The solution passes through the filtration
system – debris and dirt are captured and the solution
is clarified. Solution is forced into the solution tank
from the recovery tank.
Clarified cleaning solution – not diminished by the
recycling process – is returned to spray the carpet.
FILLING THE SOLUTION TANK
1. Unplug the machine and move the machine next
to a water source.
WARNING: Hazardous voltage. Shock
or electrocution can result. Unplug power
cord before working on machine.
2. Remove the solution tank cover, letting it hang
on the side of the machine.
3. Using a clean bucket or hose, partially fill the
tank with water through the fill opening.

solution may enter and damage the vacuum motor.
6. Place the solution tank cover on the solution tank
and make sure the cover gasket seals the tank.
PREPARING FLOOR FOR CLEANING
1. Remove loose objects or debris as they will plug
squeegee openings and cause streaking and
poor water pickup.
2. Remove gum or other such materials stuck to
the floor with a putty knife or scraper.
3. Determine which cleaning mode is best for the
floor condition, standard or recycle .
SELECTING CLEANING MODE
(For Recycle Models Only)
The recycle model can be used in either the standard
or recycle cleaning mode.
STANDARD CLEANING MODE
Standard cleaning mode means that fresh
solution is dispensed from the solution tank and
used solution is picked up by the vacuum
system and deposited in the recovery tank.
When the recovery tank is full, it is emptied and
the solution tank is refilled. This cleaning mode
is recommended when carpeting is extremely
soiled and requires restoration.
To select standard cleaning mode, remove the
recovery tank cover and turn the recycle valve
clockwise (OFF).

must be freeze protected. See FREEZE
PROTECTION .
WEEKLY
Remove and flush out the solution dispensing
nozzles in the intake head and powerbrush
head.
Clean and flush out the vacuum intake nozzle in
the intake head at the front of the machine.

SOLUTION SYSTEM
The solution system can accumulate an alkaline
buildup. The pumping/nozzle system should be
flushed monthly, or more often if hard water is used.
RINSING SOLUTION SYSTEM
1. Mix a solution of 1 L (0.26 gal) white vinegar to
8 L (2.1 gal) water.
2. Pour the solution into the solution tank. Position
the machine over a floor drain.
3. Plug in the power cord and press the bottom (l)
of the hand tool switch. The pump will start and
spray through the nozzles to the floor.
4. Run the pump until all solution has been
dispensed through system.
5. Rinse the solution system again with 8 L of
water only. Check the solution dispensing
nozzles for plugging.
SOLUTION DISPENSING NOZZLES
AND VACUUM INLET
The intake head contains four solution dispensing
nozzles. There is also one dispensing nozzle
contained in the powerbrush head. Remove and rinse
these nozzles every week, or if they are plugged.
Remove any debris caught in the vacuum inlet and
flush with water.
ATTENTION: Plugged nozzle(s) can cause
streaking of carpets, and create a back-pressure
that can damage the solution pump. Always
remove and clean nozzles as soon as plugging
occurs.
To clean nozzles and vacuum inlet:
1. Unplug the power cord from the wall outlet.

FREEZE PROTECTION
Freeze protection of the machine is necessary to
prevent damage to components of the solution
system if the machine is going to be exposed to
freezing temperatures.
ATTENTION: Freezing temperatures can severely
damage components. Do not store or transport
machine in areas where freezing of solution
contents could occur, unless machine is freeze
protected. Failure of components due to lack of
freeze protection voids the warranty on such
components.
To protect machine from freezing:
1. Move machine over floor drain and plug the
power cord into an outlet. Drain both tanks.
2. Pour 2 L (0.53 gal) of pre-mixed
automotive-type windshield washer solution into
solution tank.
ATTENTION: Do not use cooling system
anti-freeze such as ethylene glycol.
3. Press the bottom (l) of the hand tool switch. The
pump will start and spray through the nozzles to
the floor. Run the pump until all solution has
been dispensed through system.
ATTENTION: Machines and attachments that have
been freeze protected must be flushed
completely prior to normal use. Follow directions
for the appropriate cleaning process, but run
your selected cleaning solution through the
system to purge all anti-freeze before starting the
cleaning process.
