Operations
Priming the Chemical Pump
1. Fill chemical container and inspect chemical
strainer.
2. Insert chemical inlet and prime tubing into chemical
container.
3. Pull out engine choke, turn solution pump switch to
override and turn ignition key to start.
4. Push in engine choke after engine has started.
5. Set throttle to idle position.
6. Turn on solution pump.
7. Turn chemical control 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.
8. Turn the chemical control valve to run. use the
chemical metering valve to set the chemical flow to
the desired flow rate while observing the flow meter
indicator. To accurately set the chemical flow, pull
the trigger on the cleaning tool while adjusting the
flow rate.
9. Set throttle to maximum position for quick unit heat
up.
NOTE: Do not run the machine with the port blocked
for more than 2 minutes to avoid overheating.
Once you have completed priming the chemical pump,
proceed with the cleaning operation. Your unit should
be in the correct throttle position for your cleaning
operation or extracting.
Always dispose of waste in accordance with Local,
State, and Federal laws.
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 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 auto-
matically 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.
Cleaning
Observe the following guidelines, while cleaning:
1. Before proceeding make sure the spray tips 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 all of the spray
tips.
b. If the spray tips are not showing a full spray pat-
tern, adjust for proper pattern, clean, or replace
spray tips, 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, applying
chemical in both push and pull strokes. Always fin-
ish 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. If shut-
down occurs due to foam created by chemicals
used, add Prochem defoamer.
