If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunc-
tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
120 VOLT MODELS
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in "Fig.
A". A temporary adaptor that looks like the adaptor in
"Fig. C" may be used to connect this plug to a 2-pole
receptacle as shown in "Fig. B", if a properly grounded
outlet is not available. The temporary adaptor should
be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green
colored rigid ear, lug, or wire extending from the
adaptor must be connected to a permanent ground
such as a properly grounded outlet box cover.
Whenever the adaptor is used, it must be held in place
by a metal screw.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check
with a qualified electrician or service person if you are
in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the appliance - if it
will not fit the outlet, have a proper outlet installed by a
qualified electrician.
Le raccordement incorrect du conducteur de terre
d'équipement peut entraîner des risques d'électrocu-
tion. Vérifiez auprès d'un électricien qualifié ou d'un
responsable de l'entretien si vous avez quelque doute
que ce soit quant au raccordement à la terre de votre
prise murale. Ne modifiez pas la fiche fournie avec
l'appareil : si elle ne correspond pas à la prise murale,
faites installer une prise adéquate par un électricien
qualifié.

Maintenance
Protect From Freezing
If it becomes necessary to store in temperatures that
could drop below 40°F, the pumping system, hoses and
valves must be protected from freezing with a methyl
hydrate window washer antifreeze solution.
NOTE: Do not use ethylene glycol or cooling system
antifreezes.
1. Add one gallon of window washer antifreeze to the
supply tank.
2. Turn on pump switch and spray until the anti-freeze
solution fills the solution lines.
3. Drain the leftover antifreeze from the supply tank.
Always allow the unit to reach room temperature
before filling with hot water or operating.
4. Before operation be sure to flush system
completely. Failure to do so after winterizing
machine will damage carpet.
Daily Regular Maintenance
Before making any adjustments or repairs to the
machine, disconnect the power cord from the elec-
trical source.
1. Empty unused cleaning solution from the solution
tank.
2. Inspect and clean filter at solution tank fill port and
at the vacuum intake port in the dome.
3. Flush pumping system with 1 to 2 gallons of clean,
hot water.
4. Check spray jet for full spray pattern.
5. Empty the recovery tank and rinse with clean
water.
6. Check for and remove any lint or debris around
brush and vac shoe.
7. Clean float screen and check float valve to make
sure it moves freely.
Periodic Maintenance
1. After every 25 hours of operation, flush a white
vinegar solution (ONE quart vinegar to two gallons
of water) or anti-browning solution (mixed as
directed) through the extractor. This will prevent
build-up of alkaline residue in the system.
2. If the spray jet becomes clogged, check for debris
and clean surface of jet.
NOTE: Do not use pins, wire, etc. to clean spray jet
nozzle as this will deform the jet and destroy the

Vacuum Motor Carbon Brushes
Carbon
Brushes
End Cap
If armature commutator is grooved, extremely pitted or not
concentric, the motor will need to be replaced or sent to a
qualified service center.
Inportant:
These brushes wear quicker as the length shortens due to
increased heat. Spring inside brush housing will damage
motor if brushes are allowed to wear away completely.
Periodically check the length of the carbon brushes. Replace
both carbon brushes when either is less tan 3/8" (9.5mm)
long.
