INSPECTION:
Carefully unpack and inspect your KING COBRA-1200 PRO 240V for shipping damage. Each machine is tested
and inspected before shipping. Any shipping damage incurred is the responsibility of the carrier. You should
notify the carrier immediately if you notice damage to the box or to the machine or parts.
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 9 pH) in the King Cobra to prevent premature wear of the pump, seals and other
components. Damage caused by the use of improper or strong chemicals is not covered by warranty. When
cleaning carpets with the 500 psi pump, we recommend our Magic Fabric Cleaner. Powders are not
recommended.
MAINTENANCE:
For optimum performance, flush the machine with clear water at the end of each working day. Once a
month, minimum, run a flushing compound through the machine to break up any mineral or chemical build-up
that may have formed.
U.S. Products “X-1500” is recommended. The vacuum motor, pump motor, and the pump do not require any
scheduled maintenance; however, the motors may require replacement brushes after 1000 - 1500 hours, and
the 1200 psi pump and unloader valve may require rebuild kits after 500 -1000 hours (refer to machine part
list for numbers). Clean the body with an all purpose detergent, and protect it with an automobile interior
polish. Lubricate the wheels, castors, and quick disconnects with an all purpose silicone spray.

OPERATION
REFER TO THE DIAGRAMS ON THE PREVIOUS PAGE
HIGH PRESSURE WASHER
1 Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
Make sure hoses are in good condition and the spray nozzle(s) is tight.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES
2. Connect the dump hose to the back of the machine, and place the open end of the hose in a drain.
Make sure the recovery tank drain hose is closed and that the lid is screwed on tight.
3. If you choose to use the auto-fill feature, connect the fill hose to the autofill valve (located over the
solution tank fill hole. Place your gallon of chemical in the chemical basket on the recovery tank lid, and
put the weighted foot valve into the gallon. Turn on the water source, and allow the tank to fill with
solution. When using the auto-fill system, the auto fill valve will automatically turn on and turn off as the
tank empties and then fills. NOTE: If you are not going to use the auto-fill system, just fill the tank with
water and cleaning chemical. Follow chemical directions regarding dilution and mixing. Do not use harsh
chemicals; they may damage seals in pumps and valves, and cause the pump to wear prematurely.
NOTE: using warm water in the tank may improve the efficiency of the heat exchanger when cleaning
with heat, but never use water with a temerature exceeding
54ºC/130ºF .
4. Pre-spray the area to be cleaned, with a pump-up sprayer, while the tank is filling. Follow chemical
directions.
5. Connect the solution hose (from the reel) to the 1200 PSI Quick Disconnect on the front of the tank,
below the switch plate. Refer to illustration on page 3.
6. Plug in the two power cords. Do not connect both cords to the same outlet. Although all systems
on the high pressure side of the machine may work correctly if you are not on two circuits, a circuit
breaker in a wall panel may trip.
Turn on the high pressure pump by placing the HIGH PRESSURE/HEAT selection switch (2) in the UP
position, to select the High Pressure Pump. NOTE: The high pressure pump and the heat can not
operate at the same time. NOTE: this switch is off when it is set to the middle position and neither the
high pressure pump or the heater is selected.
7. Prime the 1200 psi pump using the ‘power prime’ system: turn on both the pump and the vacuum,
cover the hole in the hose barb with your hand, then depress the Power Prime Pedal. This will pull trapped
air through the pump and into the recovery tank , priming the pump. You will notice a ‘tone’ change from
the pump (smoother, with less of a rattle), and the water being pulled into the recovery tank will change
to a clear, solid stream. Priming may take 20 - 60 seconds and will require a full solution tank. When
the pump is primed, let off the Power Prime Pedal, and turn off the pump and the vacuum. Depress
the Power Prime Pedal once again, for a moment, to release the line pressure. Proceed to the next step.
8. Add defoamer to the recovery tank.
9. Attach the solution spray hose to the solution quick disconnect. Attach the vacuum hose to the hose barb
on the front of the recovery tank. Pull the hoses out from the reel. Attach the other ends of the hoses
to the cleaning tool.
10. Turn on the vacuum (3) and turn on the dump pump (5). Begin spraying. NOTE: the dump pump will
automatically turn on and turn off as the tank fills and then empties (refer to drawings on page 8).
11. When the job is finished, turn off the water source. Vacuum the remaining solution from the holding tank
into the recovery tank.
12. Run a few gallons of clean water through the system. Completely 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.
13. Unplug the power cords.
14. Clean the machine and the tool.
CAUTION : Use care when handling hazardous chemicals.
CAUTION : Never leave the 1200 psi pump running when you are not actively using it.
DANGER: Do NOT use solvents, or any chemicals that may be flammable, explosive
or combustible.

LOW PRESSURE AND HEAT
1 Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
Make sure hoses are in good condition and the spray nozzle(s) is tight.
REFER TO THE AUTO FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGE
2. If you choose to use the auto-dump, connect the dump hose to brass hose fitting on the back of the
machine, and place the open end of the hose in a drain and make sure the recovery tank drain hose is
closed, and the lid is tight on the recovery tank. Otherwise, just make sure the brass cap is on the hose
connector.
3. If you choose to use the auto-fill feature, connect the fill hose to the autofill valve over the solution tank.
Place your gallon of chemical in the chemical basket, and put the weighted foot valve in the gallon. Turn
on the water source, and allow the tank to fill with solution.
If you are not going to use the autofill system, just fill the tank with water and cleaning chemical. Follow
chemical directions regarding dilution and mixing. Do not use harsh chemicals; they may damage seals in
pumps and valves, and cause the pump to wear prematurely. NOTE: using warm water in the tank
may improve the efficiency of the heat exchanger when cleaning with heat, but never use water with a
temperature exceeding
54ºC/130ºF .
4. Select ‘HEAT” by moving the HEAT/HIGH PRESSURE switch towards the thermometer symbol. NOTE:
this switch is off when it is set to the middle position and neither the high pressure pump or the heater is
selected. When set to the bottom position, the heat is selected; the red light will come on and stay on.
NOTE: The heater and the high pressure pump can not operate at the same time.
5. Plug the power cords into separate circuits. Although all systems in the machine may work correctly if you
are not on two circuits, a circuit breaker in a wall panel may trip.
6. Press the ‘power prime’ pedal (located on the rear, lower left of the machine) for a moment to release
any back pressure in the pump lines.
7. Connect the solution hose to the 500 psi Quick Disconnect on the lower, right -front of the machine, and
connect the vacuum hose to the hose barb on the top, left of the recovery tank. Connect both hoses to
the cleaning tool
8. Turn on the 500 PSI pump (4).
9. Spray for a few seconds to fill the lines with solution. Wait two minutes to allow the heater to reach
temperature.
10. Begin cleaning. It may take several cycles to heat the lines and the cleaning tool.
11. If you are not using the autofill and autodump features, turn off the pump and vacuum when the solution
tank gets low, fill the solution tank, and empty and clean the recovery tank.
12. When finished with the job, turn off the water source. Vacuum the remaining solution from the holding
tank into the recovery tank. Run a few gallons of clean water through the system. Drain the recovery
tank by placing the drain hose over a drain or into a bucket and removing the cap. When the tank is
empty, cap the drain hose and place it back in the Velcro
®
holder. Disconnect the hoses from the cleaning
tool, and reel them up onto the hose spool.
13. Unplug the power cords.
14. Clean the machine and the tool.
NOTE: to remove the complete reel, with hoses, from the machine, pull the vacuum hose loose from the
hose barb on the front of the tank, and push the short piece of vacuum hose into the center of the hose
spool. Disconnect the solution hose quick coupling. Grasp the spool on both sides, 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.

USING THE AUTO-FILL AND/OR AUTO-DUMP FEATURES
1Chemical Supply:
• Place the container of concentrated chemical cleaner -- use a product with a pH between 7 and 9
to avoid premature pump wear, which would void the warranty -- in the holder on top of the recovery tank.
• Remove the cap on the container.
Insert the end of the clear tubing with the foot valve into the container. NOTE: the stainless steel weight at
the foot valve will keep the valve at the bottom of the chemical container.
• The chemical flow may be turned on or off by applying the pinch clamp to the tubing, between the
chemical container and the autofill valve.
2Chemical Injection Flow Rate:
• Metering tips are used to control the rate at which the cleaning chemical feeds into the supply water.
The following table illustrates the ratio of chemical, in ounces, to each gallon of water coming into the
tank. The tips are color coded for ease of use.
• NOTE: the flow rate values in the table are based on a chemical with the same viscosity as water.

CAUTION: USE CARE WHEN HANDLING
HAZARDOUS CHEMICALS.
DANGER: DO NOT USE SOLVENTS, OR ANY
CHEMICALS THAT MAY BE FLAMMABLE,
EXPLOSIVE OR COMBUSTIBLE.
3Operation:
• Attach a 3/4” garden hose to the autofill valve, and connect the other end of the hose to your water source.
• Make sure the float that hangs from the autofill valve into the tank is free of obstruction and can move
freely.
• Turn on the water supply.
• As the tank fills, the chemical concentrate will be drawn from the chemical container, will pass through the
clear tubing to the valve, and will be mixed into the water stream.
• The autofill float will automatically shut-off the flow of incoming water when the tank is nearly full, and it will
allow the valve to open again once the water level has dropped to a predetermined level.

To change the metering tip: find the black, plastic hose-clamp on the chemical feed tubing, near the Auto-fill
valve. Refer to illustration. Open the clamp by sliding the two ends of clamp (where they come together) apart
sideways, in opposite directions, with a screwdriver, until the clamp opens. Then pull the clear chemical supply
hose off the hose barb at the Auto-Fill valve. Unscrew the metering tip from the end of the hose barb. Select
the tip that will provide you with the appropriate chemical ratio (see chart, above). Screw the selected tip into the
end of the hose barb. Snug-up the tip, but do not overtighten. Slide the hose back over the tip and the hose
barb. Install the clamp onto the hose so it is over the hose barb, and squeeze the clamp closed.

1Operation:
Before each use: if necessary, unscrew the stainless steel filter inside the recovery tank and clean
it. Also make sure the float in the recovery tank is clean.
• Attach a 3/4” garden hose to the dump pump outlet fitting on the back of the base of the machine.
Refer to illustration below.
• Run the other end of the hose into a drain.
• Turn the dump pump switch ON (switch is located on the switch panel on the top of the machine).
• NOTE: the dump pump will only run when the tank is full enough to activate the float switch.
• NOTE: the pump is ‘self-priming.’ You should see water start to flow within 30 seconds of the
pump turning on. If water does not begin to flow, check the filter to see if it is plugged with debris.
After each job : run clear water though the dump pump to wash out any chemical residue.
Remove and clean the stainless steel filter in the back of the tank. Reinstall the filter once it is
clean. Clean and empty the recovery tank.
DANGER: DO NOT USE SOLVENTS, OR ANY CHEMICALS THAT MAY BE
FLAMMABLE, EXPLOSIVE OR COMBUSTIBLE.
CAUTION: always use a defoamer in the recovery tank to prevent water or foam from
entering the vacuum motor.
CAUTION: if the dump pump is not going to be used for a month or longer, remove the pump
impeller cover, pull the rubber impeller out, clean it and apply a generous coating of petroleum
jelly to the impeller before replacing it in the pump. Make sure the gasket is in place and in good
condition before you screw the impeller cover back on.
AUTO-DUMP
DANGER: always unplug the King Cobra from the electrical outlet(s) before
cleaning or maintaining. Certain internal components are electrically live,
even with switches in their OFF position.
