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. Pour clean, hot water into the solution tank.
To avoid possible tank distortion, water
temperature must not exceed 140 F (60C).
6. Add a non-foaming cleaning solution
concentrate, for use in hot water extractors at
the proportions noted on the container (See list
below), into solution tank.
7. Turn pump and vacuum switch(s) to the on
position.
8.
Start cleaning.
To prevent possible disease hazard, before
attempting to clean bodily fluids spills, you must
kill any viruses, germs or bacteria present in the
bodily fluid.

CLEANING & EMPTYING TANKS
Always use defoamer if foaming occurs. Foam
will suspend large particles which may damage
vacuum as well as allow liquid into the vacuum
motor 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 while vacuuming is done on the
pull
stroke. For heavily soiled carpets the hand tool
may be used in the 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 recovery tank will
impede the vacuum flow when the tank is full.
When this occurs, empty the recovery tank. Do
this by opening the dump valve located at the
front of the machine.
NOTE:
Dispose of waste in
a proper manner which would not violate any
Local, State or Federal law.
5.
Once the recovery tank has been emptied, you
may once again proceed with cleaning
Operating Vacuum after shutoff has activated could
draw water directly into the vac motor. This will
cause damage to the motor, therefore voiding your
warranty.

Also, to avoid prolonged
drying times, do not spray too much solution in any
one area.
Before making any adjustments or performing
any maintenance to your machine, disconnect
the power cord from the electrical source
