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 130 ºF/54 ºC 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-150 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.
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 and the pump do not require any scheduled maintenance; however, the
motor may require replacement brushes after 1000 - 1500 hours. 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
1 Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2 Fill 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 Plug in the power cords. Do not connect both cords to the same outlet; the green, circuit locator light (3)
on the switch plate should light up. If the locator light does not come on, try different outlets with one of
the cords until it does. If you are certain the cords are on separate circuits, but the green light still does not
light up, turn on the Bypass switch (1). CAUTION: using the bypass switch when the cords are on the same
circuit may cause the circuit breaker in the wall to trip. NOTE: the receptacle on the left (viewed from behind
the machine) powers the heater. The red light (2) will come on when the heat exchanger is actively heating.
4 Add liquid cleaning solution, with a pH of between 5 and 10, to the solution tank.
5 Attach the spray hose to the solution quick disconnect and the vacuum hose to the hose barb on the
recovery tank. Pull the hoses off the reel to the desired length. Attach the other ends of the hoses to
the cleaning tool.
6 Allow the heat exchanger two minutes to reach operating temperature.
7 Turn on the pump (6). Turn on the vacuums (4& 5).
8 Begin cleaning using the correct hoses and tool. Spray about three strokes, then stop spraying and do a
vacuum only pass over the are just wetted. Move on to the next area. Spray for only 8-10 seconds on each
spray pass.
9 Use defoamer in the recovery tank any time foaming occurs.
10 Monitor the water level in the solution tank. Do not let the pump run dry.
11 When the solution tank gets low, turn both the pump, and the vacuums off, fill the solution tank, empty
and clean the recovery tank.
12 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 into
a bucket or drain, and then remove the cap.
DUAL CORD SENSOR CIRCUIT:
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 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, or heat, switch is turned on when both cords are on the same circuit, the breaker may trip.
BYPASS SWITCH:
The bypass switch completely bypasses the circuit locator. Use this feature when you cannot get the green light to
come on and you believe that the two cords are on separate circuits.
CAUTION: If the bypass switch is on and the two cords are plugged into the same circuit, the breaker may blow.
BALL FLOAT VACUUM SHUT-OFF:
Prior to using the machine, always check that the float filter is clean and the ball can travel freely. When the
recovery tank is full, the ball float will rise and will shut off the vacuum flow to prevent any more water from
entering the tank. When this occurs, turn off the vacuum and empty the recovery tank.
NOTE: if foam is present, or if the ball float is prevented from rising, the float will not be able to stop the air flow,
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.
