Operations
Priming the Chemical Pump
1. Fill chemical container and inspect chemical
strainer.
2. Insert chemical inlet 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 the solution pump.
7. Turn chemical valve to prime and allow chemical to
circulate. After all air bubbles have been removed
from chemical tubing, turn the valve to Chem
position.
8. Turn chemical flow setup valve to setup position.
Use the chemical metering valve to set the
chemical flow to the desired flow rate while
observing the flow meter indicator. To accurately
set chemical flow, pull the trigger on cleaning tool
while adjusting chemical flow rate. Turn the
chemical flow setup valve to Chem position.
9. Set throttle to maximum position for quick unit heat
up.
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.
NEVER dispose of waste in storm drains, waterways,
or on ground areas. Always dispose of waste in accor-
dance with Local, State, and Federal laws.
Waste Pumpout (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 cleaning spray tips.
b. If the spray tips are not showing a full spray
pattern, adjust for proper pattern, clean, or
replace spray tips, if required.
2. Normally chemical is applied on the push stoke of
the wand, and 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
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. If
shutdown occurs due to foam created by chemicals
used, add Prochem defoamer to utilize full tank
capacity.
