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 attach-
ments.
•Never add water over 130º F/54º C to the solution tank.
•Do not use with a 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 COBRA PLUS-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, such as our Magic Fabric Cleaner. 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 6 and 9 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. U.S. Products “X-1500” is recommended.
Lubricate the wheels, castors, and quick disconnects with an all purpose silicone spray. The
vacuum and the pump do not require any maintenance; however the vacuum motors may
require new brushes after 1000 - 1500 hours. Clean the body with an all purpose detergent,
and protect it with an all purpose silicone spray like automobile interior polish.

SWITCH PLATE
BYPASS SWITCH (1):
Turning on this switch (switch illuminates when on) bypasses the circuit locator system. See OPERATION for
a description of the Bypass Switch
RED LIGHT (2):
When this light is illuminated, it confirms that the machine is on two separate circuits
GREEN INDICATOR LIGHT (3):
When this light is illuminated, it confirms that the machine is on two separate circuits
VACUUM (4), VACUUM (5), AND PUMP (6) SWITCHES:
These switches are all powered by cord #1. Switches are on when illuminated.

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 light up, turn the Bypass switch (1) on. 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 turn on when the heat
exchanger is actively heating.
4 Add liquid cleaning solution, with a pH of between 6 and 9, 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 real 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 Vacuums 1 and 2 (4& 5) and turn on the pump (6)
8 Begin cleaning using the correct hoses and tool.
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 vacuum 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, and the tank may over fill. Water damage to the vacuum motors is not covered by warranty.
CAUTION: to avoid vacuum motor damage, always use a defoamer any time foam is present.
