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
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.
This switch allows you to select either the 1200 psi pump without heat or the 500
psi pump and heat. *NOTE: Both the 1200 psi pump and the heat exchanger can not
operate at the same time. This switch allows you to select the pump, but it does not turn
on either pump.
This light will turn on when the switch is set to the 1200 PSI pump.
This switch turns on the vacuum.
This switch turns on the solution pump - either 1200 psi or 500 psi, depending on where
you have set the pump selection switch (2).
This last switch turns on the automatic pump-out pump. Use this when you want the
machine to automatically pump out the recovered solution.
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.
2. When not using the auto-dump feature, just make sure the brass cap is screwed tightly on the hose connector fitting 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
machine, 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. Connect the solution hose (from the reel) to the 1200 PSI Quick Disconnect on the front of the tank, below the switch plate.
6. 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.
8. 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 to release any built-up back pressure. Proceed to Step 9.
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.

FORM NO. 56041961 - 7
OPERATION OF THE 1200 PSI PUMP CONTINUED:
9. Your machine has two solution outputs. The solution output for the 1200 psi pump is a quick disconnect located just below
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.
10. Turn on the vacuum (3) and turn on the Automatic pump-out pump (5),if you have set-up the dump hose. Begin cleaning.
11. 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.
12. 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.
13. Unplug the power cords.
14. Clean the machine and the tool. 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.
2. If you choose to use the auto-dump feature, 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. 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 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.

8 - FORM NO. 56041961
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: if necessary, unscrew the stainless steel filter at the bottom of 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 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 the water level in the tank is high enough to activate the float switch. 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 bottom of the tank. Reinstall the filter once it is clean. Clean and empty the recovery tank.
