IMPORTANT SAFETY INSTRUCTIONS
This machine is only suitable for commercial use, for example in hotels, schools,
hospitals, factories, shops and offices other than normal residential housekeeping
purposes.
When using any electrical appliance, basic precautions should always be followed,
including the following:
NOTE: Read all instructions before using this machine.
WARNING!
To reduce the risk of fire, electric shock, or injury:
•Do not leave the machine unattended when it is plugged in. Unplug the unit from the outlet
when not in use and before servicing.
•To avoid electric shock, do not expose to rain or snow. Store, and use, indoors.
•Do not allow to be used as a toy. Close attention is necessary when used near children.
•Use only as described in this manual. Use only the manufacturer’s recommended
attachments.
•Never add water over 130º F/54º C to the solution tank.
•Do not use with damaged cord or plug. If the machine is not working as it should, has
been dropped, damaged, left outdoors or dropped into water, return it to a service center.
•Do not pull by the cord, use the cord as a handle, close a door on the cord, or pull the cord
around sharp edges or corners. Do not run the machine over the cord. Keep the cord away
from heated surfaces. To unplug, grasp the plug, not the cord.
•Do not handle the plug, the cord or the machine with wet hands.
•Extension cords must be 12/3 and no longer than 50 feet. Replace the cord or unplug
immediately if the ground prong becomes damaged.
•Do not put any object into openings. Do not use with any opening blocked; keep free of
dust, lint, hair, and anything that may reduce air flow.
•Keep loose clothing, hair, fingers, and all parts of body away from openings and moving
parts.
•Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot
ashes, or any health endangering dusts. Do not use to pick up flammable or combustible
liquids such as gasoline or use in areas where they may be present.
•Turn off all controls before unplugging.
•Use extra care when cleaning on stairs.
•Connect to a properly grounded outlet only.
•Liquid ejected at the spray nozzle could be dangerous as a result of its temperature,
pressure, or chemical content.

INSPECTION:
Carefully unpack and inspect your KING COBRA-500 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:
We recommend liquid cleaning chemicals. Powder chemicals may be used, but unless mixed very thoroughly
they could cause a build-up in the pump, lines, heat exchanger and/or quick disconnects. Any problem
caused by a chemical build-up is not covered by warranty. Use a neutral cleaner with a pH between 5 and 10 to
avoid premature wear of the pump, seals, and/or other components. Damage caused by the use of strong
chemicals is not covered by the warranty.
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 motor, and the pump do not require any scheduled
maintenance; however, the motors may require replacement brushes after 1000 - 1500 hours. The pump may
require rebuild kits after 1000 - 1500 hours, typically, and the pump unloader valve may need to be replaced
after approximately 1000 - 1500 hours of use (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.

REDLIGHTINDICATES
HEATER IS HEATING
1 Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2Fill the solution tank with water. Using warm water may be a benefit in cleaning effectiveness, but
do not use hot water (above 130
°
F / 54
°
C) in the tank.
3 Screw the lid on the recovery tank. Close the dump hose.
4 Plug in the power cords. Do not connect both cords to the same outlet; the green, circuit locator light
(1) on the switch plate should light up. If the locator light does not come on, try different outlets until it
does. If you are certain the cords are on separate circuits, turn the Bypass switch (2) on.
CAUTION: using the Bypass switch (2) when the cords are on the same circuit may cause the
breaker in the wall to trip. NOTE: the receptacle on the left (viewed from behind the machine) powers
the heater.
The red light (6) will turn on only when the heat exchanger is actively heating.
OPERATION
be sure to register your warranty -- www.usproducts.com

5 Connect the priming/siphon hose to the machine, turn the pump ON by turning the pump pressure knob
(4) up to increase pump speed, and turn the vacuum switch (3) on. Hold the rubber ‘cork’ against the
vacuum inlet hose barb on the recovery tank. The pump should prime between 20 - 60 seconds. Watch
the water flow into the recovery tank through the clear lid. When the water is clear (no air in it) and
flowing strongly, turn both the pump and the vacuum off, and remove the priming hose.
Priming may take 20 - 60 seconds, and the solution tank should be full.
6 Add liquid cleaning chemical, with a pH between 6 and 9, to the solution tank.
7 Attach the spray hose (from the reel) to the solution quick disconnect and the vacuum hose to the
hose barb on the recovery tank. Pull the hoses out from the reel. Attach the other ends of the hoses
to the cleaning tool.
8 Set the temperature knob (5) to the desired heat setting. Allow the heat exchanger two minutes to
reach operating temperature. The red light (6) 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 the pump on by setting the pressure adjust knob to the desired spraying pressure (0 - 500 PSI).
Read the spraying pressure at the pressure gauge (7) 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 on (3). 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, fill the solution tank, empty
and clean the recovery tank.
14 When finished 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.
This unique, patented system is operated by a solid state circuit. It will inform the operator when the two
cords are plugged into separate circuits by turning on the green, circuit locator light. This helps to prevent
tripping circuit breakers. NOTE: if the green, circuit locator light does not illuminate when the cords are
plugged in, then both cords are on the same circuit. Try other outlets with one of the cords until you get
the locator light to come on. NOTE: if the bypass switch is turned on when both cords are on the same
circuit, the breaker in the wall may trip.
ELECTRIC CIRCUIT LOCATOR
REFER TO THE DIAGRAMS ON THE PREVIOUS PAGE
ELECTRONIC FLOAT SHUT-OFF
When the recovery tank is full, the electronic float switch will turn the vacuum motor off. This will
prevent water from entering the vacuum motor. The float may not work properly if the float filter rod
is dirty or if there is heavy foam in the tank
. To reset, turn the Vacuum switch off, and empty the
tank.
CAUTION: to avoid vacuum motor damage, always make sure the float filter is clean and that it
can travel freely before you operate the machine. Always use a defoamer any time foam is present.
