OPERATING
INSTRUCTIONS
DO NOT OPERATE MACHINE UNTIL YOU HAVE READ
ALL SECTIONS OF THE INSTRUCTIONS
IMPROPER USE OF THE MACHINE WILL VOID THE WARRANTY
1. Always use a defoamer when foaming occurs to prevent vacuum motor damage.
2. Keep machine from rain and snow, extremes in temperatures, and store in a
heated location. Use the machine indoors. Do not use outdoors.
3. Do not let the pump run dry.
4. Use approved chemicals only. NO SOLVENTS.

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-310 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. Clean the body with an all purpose detergent, and protect it with an automobile interior
polish.

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 (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 ON (2). This will allow the heater to turn 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 red light will turn on only when the heat exchanger is
actively heating.
4 Connect the priming hose to the machine, turn the pump switch ON (6) and prime the air out of
the pump by allowing the water to flow unrestricted. 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 (4). 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.
Once the pump is primed, turn the pump and the vacuum OFF. Remove the 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 of the reel. Attach the other ends of the hoses to the cleaning tool.
7 Allow the heat exchanger two minutes to reach operating temperature. The red light (3) will go out
when the heater has reached maximum operating temperature.
8 Turn the pump on and set the pressure selection switch to the desired spraying pressure: 300 or 50
PSI).
9 Turn the vacuum ON.
10 Begin cleaning using the correct hoses and tool.
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 the pump and the vacuum off, 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 into a bucket, and remove the hose cap. Disconnect the hoses from the cleaning tool,
and reel the hoses up onto the hose spool.
NOTE: to remove the reel, with the 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 the vacuum hose into the
center of the spool. Grasp the spool on 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 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.
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. Turn off the vacuums, 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.
