SET-UP AND OPERATION
CAUTION!
Use care when handling hazardous chemicals.
Never leave the machine running when you are not actively using it.
To avoid vacuum motor damage, always make sure the fl oat fi lter is clean and that it can travel freely before you operate the machine. Always use a defoamer
any time foam is present.
DANGER!
Do NOT use solvents, or any chemicals that may be fl ammable, explosive or combustible.
CLEANING SOLUTIONS:
Select a proper pre-spray for the surface to be cleaned, and apply the pre-spray. Use a neutral pH rinse or detergent (6 to 10 pH) in the King Cobra to prevent
premature wear of the pumps, seals, and other components. Damage caused by the use of improper or strong chemicals is not covered by warranty. Powdered
chemicals are not recommended.
1
Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness. Make sure the hoses are in good condition and the
spray nozzle(s) is tight.
2
Fill the solution tank with water. NOTE: Using warm water in the tank may improve the effi ciency of the heat exchanger when cleaning with heat, but never
use water with a temperature exceeding 130 °F / 54 °C.
3
Add liquid cleaning chemical, with a pH between 5 and 10, to the solution tank, or pre-spray the area to be cleaned, with a pump-up sprayer, while the tank is
fi lling. Follow chemical directions.

Plug in the power cords (17).
up. If the locator light does not come on, check the circuit breaker box in the wall, and/or try different outlets until it does turn on.
cords are on separate circuits, turn the Bypass switch (D) on.
CAUTION: using the Bypass switch (D) when the cords are on the same circuit may cause the breaker in the wall to trip. NOTE: the
receptacle (15) on the left (viewed from behind the machine) powers the heater.
The red light (E) will turn on only when the heat exchanger is actively heating.
5
Press the lever on the Pressure Relief Valve (18) to make sure there is no back pressure in the system.
6
Connect the Priming/Siphon Hose (14) to the Solution Hose Quick Connect (6), turn the Pump Switch (B) and the Vacuum Switch (F) ON.
Place the open end of the priming hose into the Vacuum inlet hose barb (1). Use your hand to block the open area in the hose barb. This
will allow the pump and the vacuum to work together to get the water moving. The air should prime out of the pump within 20 - 60 seconds.
Watch the water fl ow into the recovery tank. When the water is clear (no air in it) and is fl owing strongly, turn both the pump and the vacuum
off, and remove the priming hose. NEVER remove the priming hose while the pump is still running.
7
Connect the Solution Hose (19) from the reel to the Solution Hose Quick Connect (6) and connect the Vacuum Hose (21) from the reel to the Vacuum Hose
Connection (1). Connect both hoses to the cleaning tool.
8
Allow the heat exchanger two minutes to reach operating temperature. The red light (E) will go out when the heater has reached operating temperature.
NOTE: The red light will be on nearly all the time as you clean.
9
Turn on the Pump (B) and set the Pressure Selection Switch (C) to the desired spraying pressure (carpet or upholstery). Read the spraying pressure at the
Pressure Gauge (23) while spraying. NOTE: When you let off the trigger on the wand, the pressure gauge reading will drop to 0 psi; however, the spraying
pressure will remain at the level to which you have set it. Turn the Vacuum Switch (F) ON. NOTE: the vacuum motor will start up slowly to prevent a large
current surge.
10
Begin cleaning.
11
Use defoamer in the recovery tank any time foaming occurs.
12
Monitor the water level in the solution tank. Do not let the pump run dry.
13
When the solution tank gets low, turn off the pump and the vacuum, fi ll the solution tank, empty and clean the recovery tank.
14
When fi nished with the job, remove any unused solution from the solution tank, and run a few gallons of clean water through the system. Drain the recovery
tank by placing the dump hose over a drain, or a bucket, and removing the cap. Disconnect the hoses from the cleaning tool, and reel them up onto the hose
spool.
NOTE: To remove the reel, with hoses, from the machine, pull the vacuum hose loose from the hose barb on the front of the tank. Disconnect the solution hose
quick coupling. Push Vacuum hose into the center of the hose spool. Grasp the spool from either side, and lift it off the machine. NOTE: before servicing any
component in the base cabinet, the hoses and spool must be removed from the machine before the tanks can be lifted open.
