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 COBRA PLUS-300 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. 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, and the pump and bypass valve may require rebuild kits after 1000 - 1500 hours,
typically (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.

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
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, turn the Bypass switch
on.
CAUTION: using the Bypass switch 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 will turn on only when the heat exchanger is actively heating.
4 Connect the priming hose to the machine, turn the pump ON by turning the pump pressure knob up to

increase pump speed, and prime the air out of the pump. When the water is clear (no air in it) turn
the pump off, and remove the priming hose. NOTE: if priming is difficult, place the open end of the
priming hose into the Vacuum inlet hose barb, and turn the vacuum on. Use your hand to block the
open area in the hose barb. This will allow the pump and the vacuum to work together to get the
water moving. Priming may take 20 - 60 seconds, and the solution tank should be full. Turn motors
off. Remove priming hose.
5 Add liquid cleaning chemical, with a pH between 6 and 9, to the solution tank.
6 Attach the spray hose 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.
7 Set the temperature knob to the desired heat setting. Allow the heat exchanger two minutes to
reach operating temperature. The red light will go out when the heater has reached operating
temperature. NOTE: the red light will be on nearly all the time as you clean.
8 Turn the pump on by setting the pressure adjust knob to the desired spraying pressure (0 - 300
PSI). Read the spraying pressure at the pressure gauge while spraying. Turn the vacuum on.
NOTE: the vacuum motor will start up slowly to prevent a large current surge.
9 Begin cleaning.
10 Use defoamer in the recovery tank any time foaming occurs.
11 Monitor the water level in the solution tank. Do not let the pump run dry.
12 When the solution tank gets low, turn off the pump and the vacuum, fill the solution tank, empty
and clean the recovery tank.
13 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 acuum hose into the
center of the hose spool. Grasp the spool from both sides, 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.
ELECTRIC CIRCUIT LOCATOR
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.
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.
