INSPECTION:
Carefully unpack and inspect your KING COBRA-1200 PRO 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 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.
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. The vacuum motor, pump motors, and the pumps do not require any
scheduled maintenance; however, the motors may require replacement brushes after 1000 - 1500
hours, and the high pressure pumps and unloader valves 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.

SWITCH PLATE
1. This green light will turn on when the two power cords are plugged into separate circuits. Try
different outlets with one cord until you can get a green light, otherwise a circuit breaker in
the wall may trip.
2. This selector switch determines whether you will use the 1200 psi pump or the heater. You
can select either, but not both at the same time. The heater will only work with the 500 psi
pump. The center position is OFF, and neither the 1200 psi pump nor the heater is turned
on. CAUTION: do not operate the 1200 psi pump and the 500 psi pump at the same time.
3. This light will turn on when the switch is set to the 1200 PSI pump.
4. This switch turns on the vacuum.
5. This switch turns on the 500 psi solution pump. CAUTION: do not run both solution pumps
at the same time.
6. This last switch turns on the automatic pump-out pump. Use this when you want the
machine to automatically pump out the recovered solution. CAUTION: do not turn on this
pump until you have connected the pump-out hose.
7. This light will turn on when you have selected heat instead of the 1200 psi pump.

1200 PSI HIGH PRESSURE WASHER
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. Be sure the pre-filter bag and
the dump pump filter are installed and are clean.
2. When not using the auto-dump feature, just make sure the brass cap is screwed tightly on the hose
connector fitting on the dump pump on the rear of the machine. If you choose to use the auto-dump,
connect the dump hose to brass hose fitting on the back of the dump pump, and place the open end
of the hose in a drain. Make sure the drain hose (recovery tank) is closed, and the lid is tight on the
recovery tank.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES.
3. If you choose to use the auto-fill feature, connect the fill hose to the auto-fill connector (located over
the solution tank fill hole). Turn on the water source, and allow the tank to fill with water. When using
the auto-fill system, the auto-fill float 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: Never use water with a temperature exceeding 130 °F / 54 °C.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES.
4. Pre-spray the area to be cleaned, with a pump-up sprayer, while the tank is filling. Follow chemical
directions.
5. Plug in the two power cords. Do not connect both cords to the same outlet. The green, ‘separate
circuit’ locator light (1) on the switch plate should light 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. 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. If you make sure the green light is turned on, you will prevent tripped circuit breakers. Turn on the
1200 PSI pump by placing the HIGH PRESSURE/HEAT selection switch (2) in the UP position, to select
the 1200 PSI Pump. NOTE: both the 1200 PSI pump and the heat can not operate at the same
time. NOTE: this switch (2) is off when it is set to the middle position and neither the 1200 PSI pump
nor the heater is selected.
6. Prime the 1200 psi pump using the ‘power prime’ system: turn on both the pump and the vacuum
(3), cover the hole in the vacuum hose barb on the top of the machine with your hand, then depress
the Power Prime Pedal (located on the back of the machine). This will pull trapped air through the
pump and into the recovery tank, priming the pump. You should notice a change in the ‘tone’ of the
pump (smoother, with less rattle), and the water being pulled into the recovery tank will change from a
white, sputtering flow to a clear, solid stream. NOTE: priming requires a full Holding tank, and it may
take between 20 to 90 seconds. Once the pump has primed, release the Power Prime Pedal, and
turn both the pump and the vacuum off. Momentarily depress the Power Prime pedal again -- after the
pump has stopped running -- to release any built-up back pressure.
SET-UP AND OPERATION
REFER TO THE DIAGRAMS ON THE PREVIOUS PAGE
CAUTION: Use care when handling hazardous chemicals.
CAUTION: Never leave the machine running when you are not actively using it.
CAUTION: Always use a defoamer when foaming occurs to prevent vacuum motor damage.
DANGER: Do NOT use solvents, or any chemicals that may be flammable, explosive or
combustible.

OPERATION OF THE 1200 PSI PUMP CONTINUED:
7. Your machine has two solution outputs. The solution output for the 1200 psi pump is a quick
disconnect located just above the fill hole on the holding tank, on the front face of the machine (the
500 psi outlet is a quick disconnect on the end of a short length of hose, on the front of the base
section of the machine). Attach the solution spray hose from the reel to the 1200 psi solution quick
disconnect. Attach the vacuum hose on the reel 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.
8. Turn on the vacuum (3) and turn on the Automatic pump-out pump (5),if you have set-up the
dump hose. Begin cleaning.
9. When the job is finished, turn off the water source (if you are using the auto-fill feature), and turn off
the pumps. Disconnect the vacuum hose from your cleaning tool, and vacuum any remaining solution
from the holding tank into the recovery tank.
10. Completely drain the recovery tank by pouring the dirty water out through the drain hose on the rear
of the machine. Disconnect the solution hose from the cleaning tool, and reel the hoses onto the hose
spool.
11. Unplug the power cords.
12. Clean the machine, the tool, the pre-filter bag, and both Stainless Steel pump inlet filters. Never store
your machine outside, and keep it from getting too hot or too cold.
SET-UP AND OPERATION
500 PSI AND HEAT
1. Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
Make sure the recovery tank drain hose is closed, and the lid is tight on the recovery tank. Make sure
the hoses are in good condition and the spray nozzle(s) is tight. Be sure the pre-filter bag and the dump
pump filter are installed and are clean.
2. If you choose to use the auto-dump feature, connect the dump hose to brass hose fitting on the dump
pump on the back of the machine, and place the open end of the hose in a drain. Make sure the drain
hose, on the rear of the recovery tank, is closed and the lid is tight on the recovery tank. If you choose
not to use the auto-dump feature, make sure the brass cap is screwed onto the hose connector on the
dump pump on the back of the machine and the dump pump switch is turned off.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES.
3. If you choose to use the auto-fill feature, connect the fill hose to the auto-fill connector (located over the
solution tank fill hole). Turn on the water source, and allow the tank to fill with water. NOTE: Do not
turn the water pressure on high; just turn the water on. When using the auto-fill system, the auto-fill
float will automatically turn on and turn off as the tank empties and then fills. If you are not going to
use the auto-fill system, just fill the tank with clean water and a liquid cleaning chemical. Follow chemical
directions regarding dilution and mixing. CAUTION: Do not use harsh chemicals in your King Cobra 1200
Pro; they may damage seals in pumps and valves and could 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 130 °F / 54 °C.

Operation:
• Attach a 3/4” garden hose to the auto fill valve, and connect the other end of the hose to your water
source.
• Make sure the float that hangs from the auto fill valve into the tank is free of obstruction and can
move freely.
• Turn on the water supply. NOTE: Do not turn the water pressure on high; just turn the water on.
• The auto-fill 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.

Operation:
Before each use: Always use a clean pre-filter bag when operating the machine.
If necessary, unscrew the stainless steel filter at the bottom of the recovery tank and clean it. Also make sure the
ball float in the recovery tank is clean.
• Attach a 3/4” garden hose to the dump pump outlet fitting on the dump pump on the back of the base of the
machine.
Refer to illustration below.
• Run the other end of the hose into a drain.
• Turn ON the dump pump switch (switch is located on the switch panel on the top of the machine).
• NOTE: the dump 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 both the pre-filter bag and the stainless steel filter in the bottom of the tank. Reinstall the filter
once it is clean. Clean and empty the recovery tank.
