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 54º C/ 130º F 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 plug 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-300H for shipping damage. Each machine is tested and in-
spected 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.

This switch is also powered by cord #1. The carpet setting (down position) is high pressure
(approximately 300 PSI). The upholstery setting (up position) is low pressure (approximately 50 PSI
with a K1 or V2 spray tip).

SET-UP:
1. Fill the holding tank with clear water and the detergent of your choice. Mix well. Although this
machine is designed to supply instant hot water, the addition of warm water (not exceeding 54º C/130º
F) to the holding tank will increase the efficiency of the heater.
2. Plug in cord #1. Attach the priming hose to the machine (see illustration on previous page). Turn the
pump on and set the switch to the upholstery setting. Run the pump until the pump is fully primed,
then turn off the pump. Remove the priming hose, and attach the cleaning hoses and tool.
3. Turn on the pump, and spray through the cleaning tool for a few seconds to fill the lines with solution.
4. Plug in cord #2 (identified by a red “H” on the back of the extractor). Wait 2 minutes for the heat
exchanger to reach operating temperature. You may now begin cleaning. It will take about 10 seconds
for the initial heat to reach the wand.
BALL FLOAT VAC SHUTOFF:
When the recovery tank is full, the float system will shut off the incoming air flow and prevent water from
entering the vacuum motors. The float may not work properly if the float filter is clogged or if there is foam in
the tank.
CAUTION: To avoid vac motor damage, always make sure the float filter is clean and the ball
travels freely before turning on the machine, and use a defoamer whenever foam is present.

TROUBLE SHOOTING:
IF THIS OCCURS CHECK THIS
NO SPRAY
PUMP DOEN’T RUN
Solution tank is empty.
Clogged spray tip.
Pump not running.
Valve on wand not operating.
No power to pump. Test the switch.
Test the motor directly to AC power.
Debris plugging cleaning tool or vacuum hose.
Drain gate is not completely closed, or seals are damaged.
Vacuum lid is not closed tight.
No power to motor. Test the switch. Test the vacuum motor.
Spraying too long. Try spraying for 12-15 seconds per cycle. Heat exchanger
needs to be flushed.
Wrong tool being used.
Too much water passing through, (longer hose, larger diameter hose, or larger
spray tip), than standard.
No power in the wall outlet - check to see if the breaker has tripped.
Check power cord for ‘opens’.
