GROUNDING INSTRUCTIONS

THIS PRODUCT IS FOR COMMERCIAL USE
ONLY.
ELECTRICAL:
In the USA this machine operates on a
standard 15 amp 115V, 60 hz, A.C. power
circuit. The amp, hertz, and voltage are listed
on the data label found on each machine.
Using voltages above or below those indicated
on the data label will cause serious damage to
the motors.
EXTENSION CORDS:
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
malfunction 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 ordinances.
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.

PRE-RUN INSPECTION
1. Check all fittings and connectors for proper
assembly.
2. Check all hoses for leaks. Repair or replace any
damaged hoses.
3. Check power cord(s) for any damage. If
damaged, replace.
EQUIPMENT SET-UP
1. Plug power cord from machine into properly
grounded wall outlet.
2. Turn vacuum motor switch on and off to make
sure there is electrical power at machine.
3. Connect vac hose to machine. Slide the swivel
cuff over the outlet on the tank.
4. Connect the hose to your machine and wand.
Pull back the knurled collar on the quick
disconnect coupler and push onto the connection
on the chassis. To avoid leaks, check to be that
a positive connection was made.
5. Using a clean container, fill the solution tank with
clean hot water. Mix in a non-foaming cleaning
concentrate for use in hot water extraction
machines, following the manufacture’s
instructions printed on container.
NOTE:When using a powder cleaner, pre-mix with
hot water in a clean container before adding to the
solution tank.
6. Turn pump and vacuum switch(s) to the on
position.
7. Start cleaning.
AUTO FILL
Connect standard garden hose from faucet to the
rear of the solution tank. Turn on water and allow
tank to fill check for leaks.
AUTO DUMP
Connect standard garden hose to the front of the
machine and run to any sanitary sewer. Check inside
the recovery tank to make sure the float switch is not
obstructed.
The auto dump (sump
pump) must never be run
dry. The float switch in the recovery tank will prevent
this. Make sure the drain screen in the recovery tank
is kept clean.

EMPTYING AND CLEANING
Always use defoamer if
foaming occurs. Foam
will suspend large particles that may damage
vacuum(s) as well as allow liquid into the vacuum
motor(s) without activating the float shutoff.
1. Before proceeding, make certain that the nozzle
is functioning properly.
a. To check, hold the wand about one foot
above the surface to be cleaned and open
the wand valve. A full spray should be
observed from the nozzle.
b. If the nozzle is not showing a full spray
pattern, adjust nozzle for proper pattern,
clean, or replace nozzle.
2. Normally, chemical is applied on the push stroke
of the wand when cleaning. Vacuuming is done
on the pull stroke. For heavily soiled carpets the
wand may be used in a scrubbing manner,
applying chemical in both the push and pull
stroke.
3. When cleaning, keep the working opening (wand
mouth) flat on the surface being cleaned. Keep
the wand moving when the valve is open.
4. The shutoff float inside the vacuum tank will
impede the vacuum flow when the vacuum tank
is full.
When this occurs, empty the vacuum tank by
opening the dump valve and dispose of the waste
in a proper manner.
5. Once the vacuum tank has been emptied, you
may once again proceed with cleaning

MAINTENANCE
86307580 NINJA1200 01/31/08
4-1
DAILY MAINTENANCE
Unplug power cords
before servicing or
making any repairs.
1. Flush the entire system, including floor tool, hand
tool, etc., with 1 to 3 gallons of clean, hot water.
2. Vacuum out the solution tank.
3. Rinse tank with fresh water. Periodically inspect
the recovery tank and decontaminate if
necessary, using a Hospital Grade Virucide or a
1-10 bleach to water solution. Wastewater should
be disposed of properly.
4. Occasionally check filter screen at the bottom of
the solution tank and rinse clean with hot water if
necessary.
5. Inspect hoses for wear. Frayed or cracked hoses
should be replaced to avoid vacuum or solution
pressure loss.
6. Inspect power cord for wear or damage. This
cable will lie on wet carpet. To prevent electrical
shock replace cords that are frayed or have
cracked insulation immediately.
7. Clean all dirt and obstructions from drain valve
and gaskets to prevent possible leakage and
premature wear.
8. Run clean water through solution pump when
work is complete.
9. Empty both tanks and rinse, run vacuum (s) for at
least one minute to dry motor(s).
10. Store with access covers removed to allow tanks
to dry.
DO NOT attempt to
repair hose! Repairing
high-pressure hoses may result in severe burns
and serious injury.
PERIODIC MAINTENANCE
1. Twice a month, flush a white vinegar solution
(One quart vinegar to two gallons of water) or
anti-browning solution (mixed as directed)
through the extractor, turning pump switch on/off
several times, flush with clean water. This will
prevent build-up of alkaline residue in the system.
2. Check hoses for wear, blockages, or damage.
Frayed or cracked hoses should be repaired or
replaced to eliminate vacuum or solution
pressure.
3. Check all handles, switches, knobs, electrical
cables and connections on your machine for
damage. If the cable insulation is broken or
frayed, repair or replace it immediately. Don’t
take chances with electrical fire or shock.
4. Clean out solution tank. Remove and clean
solution screen.
5. Clean outside of all tanks and check for damage.
MONTHLY MAINTENANCE
1. Check all bearings for noise and wear.
2. Check all gaskets for wear and leakage.
3. Check pump pressure; observe spray pattern and
check gauge if necessary.
4. Check overall performance of machine.
SEMI-ANNUALLY
1. Check vacuum motor brushes.
LUBRICATION
For pressure regulator and pump cam lubrication,
use a light silicone lubricant which will not damage o-
rings. A small tube (86246790 - PRV NO. 51391) is
supplied with your machine.
STORAGE
Thoroughly clean machine if it is to be stored. You
must protect this machine from freezing while in
storage.
Make sure both recovery and solution tanks are
empty and wipe dry.

MAINTENANCE
86307580 NINJA1200 01/31/08 4-
2
Only qualified
maintenance personnel
are to perform the following repairs.
VACUUM MOTOR REPLACEMENT
1. Turn off all switches and unplug machine.
2. Remove recovery tank.
3. Locate the vacuum motor wires and disconnect
at the connector.
4. Remove the vacuum motor.
5. Reverse process to install vacuum motor.
SOLUTION PUMP REPLACEMENT
1. Turn off all switches and unplug the machine.
2. Remove recovery tank.
3. Remove solution hoses from fittings in pump.
4. Remove the screws that fasten the pump to the
frame.
5. Reverse process to install pump.
VACUUM MOTOR CARBON BRUSH
REPLACEMENT
The green ground wire
must be attached for
safe operation.
1. Remove retaining clip with flat tip screw driver.
2. Replace carbon brush (A), by disconnecting at
the terminal connection (B).
3. Insert carbon brush into vac motor.
4. Replace clip and press down until it locks in
place.
Important:
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 than
3/8" (9.5mm) long.
