ELECTRICAL
This machine operates on a standard, 15 AMP, 115 volt AC circuit and has a
grounded plug.* Make sure the machine is connected to an outlet having the
same configuration as the plug. No ungrounded adapter should be used with
this machine.
*Special voltage models available.
GROUNDING INSTRUCTIONS
This machine must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce the
risk electric shock. This machine 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 ordinance
WARNING:
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.
This machine is for use on a nominal 120-volt circuit, and has a grounding plug
that looks like the plug illustrated in sketch A. A temporary adapter that looks like
the adapter illustrated in sketches B and C may be used to connect this plug to a
2-pole receptacle as shown in sketch B if a properly grounded outlet is not
available. The temporary adapter should be used only until a qualified electrician
can install a properly grounded outlet (sketch A). The green-colored rigid car, lug,
or the like extending from the adapter must be connected to a permanent ground
such as a properly grounded outlet box cover. Whenever the adapter is used, it
must be held in place by a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the
Canadian Electrical Code.

Sketch A Sketch B Sketch C
STRAIN RELIEF
Attaching the strain relief/cord retainer to the 50’ power cord.
1. Make a loop in power cord approximately 12” from receptacle end.
2. Slide cord loop through slot in retainer and over retainer arm.
Pull slack cord back through slot to secure. Attach retainer to handle.
EXTENSION CORD
If an extension cord is used, the wire size must be at least one size larger, (12-3)
than the power cord on the machine.
REQUIRED CLEANING CHEMICALS
Use only commercial low foam cleaning chemicals that are designed for carpet
extraction.
1. General carpet extraction cleaner added to the solution tank.
2. Traffic lane per-spray usually applied with spray wand.
3. Defoamer only goes into the recovery tank.
CAUTION: Use as directed. Do not over use the cleaning chemicals.

10
CLEANING TIPS
xCheck the condition of the carpeting. If the carpet is loose, heavily soiled,
stained, spotted or badly worn, point this out to the person in charge.
xLocate an inconspicuous spot on the area to be cleaned. Test carpet for
colorfastness before proceeding. Pour the concentrated cleaning solution on
the spot, cover with a white towel and place a heavy object on top to absorb
the cleaning solution. Wait 10 minutes for any reaction to take place.
Remove weight. If there is no color transfer, it should be safe to clean.
xRemove the furniture from the area to be cleaned. Large pieces can be
moved to opposite end of the room from where you start cleaning and replace
when it is completed. After cleaning carpet, place a small square of
aluminum foil or 6-mil poly square under the furniture legs to prevent moisture
from damaging the finish or rusting the metal glides.
xClean the area first with a Clean-Air Carpetkeeper, upright vacuum. Do not
use the Marathon 2000 as a dry vacuum! Heavily soiled carpet or areas of
concentrated foot traffic should be treated with recommended pre-spotting or
pre-spray chemicals, using a hand spray trigger bottle or pump up sprayer.
Do not allow any spotter or pre-spray to dry on the carpet.
xIdentify the type of carpet fiber to be cleaned. Most commercial carpet fibers
in use are nylon or acrylic based. Best results in cleaning would be obtained
if hot water is used to clean these types of fibers. On the other hand, hot
water could shrink natural fiber carpeting, like wool and cotton in particular.
Exercise caution when cleaning natural fibers. Use cool water test for
colorfastness and apply the least amount of cleaning solution possible.
xPlan your cleaning route. Always try to have the cord to the right of the
Marathon 2000 extractor so you are working away from the cord. Operate the
extractor in parallel passes. Clean the perimeter last. Turn “off” spray switch
in turns to conserve cleaning solution.
xTo decrease dry time, go over the carpet without pressing carpet spray
switch. To further decrease the drying time, use the Windshear 3000 Carpet
Blower.
xWhen running the Marathon 2000 extractor, do not overfill the recovery tank.
Do not allow the water level to rise above the clear dome on top of the
recovery tank.
xIf the spray jets become clogged, remove the spray bar assembly or the
individual spray tips and soaks them in a mild acid or anti-browning chemical
to dissolve normal alkaline chemical buildup.
xWhen the Marathon 2000 extractor runs out of cleaning solution, as noted by
streaking or incomplete cleaning, turn off the machine and drain the recovery
tank. Refill as needed and continue cleaning.

OPERATION INSTRUCTIONS
Main Controls:
Your Marathon 2000 extractor is equipped with (4) main switches, which
control the spray bar, the brush motor, the vacuum motor and the main power.
The main switch must be activated before operating the transaxle drive. The
machine will glide easily across the floor when pushed forward (without power).
The machine will also be able to be pulled back easily when the power is on or
off. The pump spray and brush will only be activated when the deadman switch is
squeezed.
WARNING:
In order to avoid injury, it is recommended that the Marathon 2000 extractor
be pulled in the reverse direction (without power) in emergency situations
only.
In addition, there is (1) main circuit breaker, (located on the front of the main
control panel):
- (20 amp) circuit breaker – main power

13
Set Up and Operation:
Your Marathon 2000 is shipped complete and ready for carpet cleaning. This
style of machine is sometimes referred to as a self-contained extractor, since
everything is included in the body of the Marathon 2000 extractor.
1. Install recovery tank cover to the top of the tank and connect the suction hose
to the cover.
2. Important! – Prior to first use: The unit has been tested with window washer
fluid at the factory, and a small amount of this fluid may remain in the system
as a precaution against freezing. Prior to first use, flush the tank and pump
system with a half-gallon of plain water.
3. Open filler door at the front of the tank and fill with hot water. Add liquid
cleaning solution to proper dilution ratio.
4. Use separate buckets to fill and empty extractor. Avoid using undissolved
soap or chemicals that could potentially plug the spray jets.
5. Attach a 12-gage extension cord to the pig tail plug on the machine.
WARNING:
To avoid serious injury: Plug into a grounded (earth) outlet only. Do not
use an adapter or remove ground pin on plug. Do not use a damaged cord.
6. Activate the main power switch. The LED light will be lit.
7. Lower the manual release lever and allow the brush assembly to rest on the
floor. The height of the suction nozzle may need to be adjusted using the turn
knob.
8. Activate the vacuum motor switch.
9. Activate the brush motor switch.
10.Activate the spray bar switch. Remember to turn off this switch about 6” from
the end of each cleaning pass.
11.Squeeze the trip lever on the main handle to move the extractor forward. The
machine has a powered transaxle, so forward movement will be quick and
easy. Turn the variable speed control clockwise to increase the forward
speed. Note that the pump or brush will not operate until the machine is in
motion and the spray and brush switches are turned on.
12.As you are cleaning, monitor the water level in the recovery tank cover. An
overflow of water in the recovery tank can damage the vacuum motor. Always
be aware of this water level.
13.The recovery tank can be drained by removing the drain hose from its support
clip and removing the drain plug. The standpipe in the recovery tank is
equipped with a metal screen cap. This cap is accessible by removing the
clear dome on top of the unit. It is recommended that this cap be cleaned
after every machine use.
14.The solution tank has a clear see through drain hose, which tells the operator
the tank level. The water in the solution tank can be drained using this hose.

14
15.While cleaning, pre-spray traffic areas and spots using the spray wand. The
spray wand is attached to a quick disconnect and is pressurized when the
MAIN SWITCH is turned on.
WARNING:
To avoid serious injury: Disconnect power before servicing. Electrical
service must be performed by an authorized service station or electrician.
Use only nonflammable commercial chemicals intended for machine
application. Do not use where explosive vapors or dust are present in the
air. Disconnect power if the machine is left unattended. Do not allow
machine to freeze. Do not expose to rain, store machine indoors.
Daily Maintenance:
1. Rinse out the recovery tank and clean the recovery dome. In addition,
remove and clean the recovery screen cap.
2. Drain the solution tank and clean with water.
3. Remove any debris in either the recovery or solution tank.
4. Flush the pumping system with clean warm water or white vinegar.
5. Remove lint or debris from the vacuum shoe or brush. Hint: if heavy lint
build-up is present, use a hacksaw blade with teeth down to remove
the lint.
Periodic Maintenance:
xIt is highly recommended that once a month you flush the Marathon 2000 out
with a 8 to 1 ratio of water to white vinegar or anti-browning solution through
the Marathon 2000 extractor. This will help to prevent the build up of alkaline
residue.
xIf the spray jets become clogged, remove and wash them thoroughly and
blow dry. Do not use wire or pins to clean the nozzles as this will cause the
spray pattern to become distorted, thereby creating a streaking pattern on the
carpeting.
xIf the spray jets drip after the pump is turned off, the solenoid valve may need
to be cleaned.
xOnce a month, inspect all electrical cables, hoses, filters and connections in
the Marathon 2000. If you see something that should be repaired or replaced
it should be reported and repaired. Little things are easy to forget about, but
as these little things add up, you end up with a cluster of problems that will
cost you in the long run.
CAUTION: When opening the Marathon 2000 for service and/or inspection, be
sure that the recovery hose is in its proper position. If not, the hose can
become crushed and you will not get good airflow from the vacuum nozzle.

15
xBe sure to use Tornado genuine parts and service is provided by an
authorized Tornado Service Center. Use of non-O.E.M. parts will void the
warranty.
PROTECT FROM FREEZING - Caution!
If it becomes necessary to store in temperatures that could drop below 40
degrees F, the pumping system, hoses and valves must be protected from
freezing with a methyl hydrate window washer antifreeze solution. Do not use
ethylene glycol or cooling system antifreezes.
Whenever unit will be stored in temperatures below 40 degrees F, empty the
solution tank, and then pour a half-gallon of pre-mixed window washer antifreeze
into the tank. The windshield washer fluid must not be diluted with water or
solution already in the tank. Turn on the brush switch and press the spray switch
until the unit runs completely dry.
Before returning the unit back to service, allow it to reach room temperature first.
Then add a half-gallon of plain water to the solution tank and flush the system
using the spray switch.
The unit has been tested at the factory with windshield washer antifreeze
solution. A small amount of this solution may remain in the system and must be
flushed out prior to first use.
