PRIMING THE CHEMICAL PUMP
1. Connect water hose to water inlet connection
and turn on water supply.
2. Connect cleaning and vacuum hoses to the
desired cleaning tool and console.
3. Insert chemical inlet and prime tubing into
chemical container.
4. Pull out engine choke and turn ignition key to
start.
5. Push in engine choke after engine has started.
6. Set throttle to idle speed.
7. Turn on water pump.
8. Fill chemical container and inspect chemical
filter.
9. Turn chemical prime valve to prime and allow
chemical to circulate. After all air bubbles have
been removed from chemical tubing, turn the
valve to the horizontal (off) position and open
the chemical metering valve, triggering the
solution flow on the cleaning tool. Set the
desired chemical flow rate while observing the
flow meter indicator.
10. Set throttle to maximum position with vacuum
port blocked off for quick unit heat up.
WASTE PUMP (OPTIONAL)
1. If your unit is equipped with an automatic waste
pump, connect one end of a garden hose to the
pump-out connection on the console and the
other end to an appropriate waste disposal.
2. Turn the pump-out switch on the control panel to
the ON position. The waste pump will operate
automatically throughout the cleaning operation.
We recommend that you use a 3/4" I.D. water
hose as a waste pump outlet hose. DO NOT use
a hose smaller than 5/8" I.D.
NEVER use your automatic waste pump outlet
hose as a water inlet hose.
NEVER dispose of waste in storm drains,
waterways, or on ground areas. Always dispose
of waste in accordance with Local, State, and
Federal laws.
Once you have completed steps 1 through 8,
proceed with the cleaning operation. Your unit
should be in the correct throttle position for your
cleaning operation or extracting. A float switch
located inside the waste tank will automatically shut
down the unit when it reaches its full capacity.
When this occurs, empty the waste tank before
continuing.
CLEANING
Observe the following guidelines, while cleaning:
1. Before proceeding make sure the nozzles are
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
cleaning nozzles.
b. If the nozzles are not showing a full spray
pattern, adjust nozzles for proper pattern, clean,
or replace nozzles, if required.
2. Normally chemical is applied on the push stoke
of the wand when cleaning and vacuuming is
done on the pull stroke. For heavily soiled
carpets the wand may be used in a scrubbing
manner, apply chemical in both push and pull
strokes. Always finish up an area with a vacuum
stroke.
3. When cleaning, keep the working opening
(mouth) flat on the surface being cleaned. Keep
the wand moving when the valve is open.
4. The unit will automatically shut-down when the
waste tank is full. This will prevent water being
drawn into the vacuum pump. If shut-down
occurs, empty the waste tank before proceeding.
