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 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, 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.
DANGER: DO NOT USE SOLVENTS OR ANY CHEMICALS THAT
MAY BE FLAMMABLE, EXPLOSIVE, OR COMBUSTIBLE
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 a common auto interior protectant.
PARTS AND SERVICE:
Repairs, when required, should be performed by your authorized distributor who maintains an inventory
of original replacement parts and accessories. Call the distributor from whom you purchased this
machine if you need parts or service. Be sure to specify the machine model. Have your serial number
handy.

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 cord.
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 on the front of the machine, and connect
the vacuum hose to the hose barb on the recovery tank. Attach the other ends of the hoses to
the cleaning tool.
6 Turn the pump on. Turn the vacuums on.
7 Begin cleaning using the correct hoses and tool.
8 Use defoamer in the recovery tank any time foaming occurs.
9 Monitor the water level in the solution tank. Do not let the pump run dry.
10 When the solution tank gets low, turn both pump and the vacuums off, fill the solution tank, and
empty and clean the recovery tank.
11 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 drain gate over
a bucket or drain, and pulling the gate handle up.
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.
CAUTION: to avoid vacuum motor damage, always use a defoamer any time foam is present.
