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:
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 power outlet when
not in use.
•Always use a defoamer when foaming occurs to prevent damage to vacuum motor(s).
•Unplug the machine from the power outlet before cleaning or servicing.
•To avoid electric shock, do not expose to rain or snow. Store, and use, indoors.
•Wear hearing protection if desired. The measured sound level of the MX 307 H is 79dB(A).
•Do not allow to be used as a toy. Close attention is necessary when used near children.
•Use only the manufacturer’s recommended attachments.
•Inspect the power cord regularly for damage, such as cracking, ageing, or damaged insulation. Replace
the power cord with the same type as original if any damage is found. Do not use with damaged cord or
plug.
•Use approved chemicals only. Never use solvents.
•Do not let the pump run dry.
•If the machine is not working as it should, has been dropped, damaged, left outdoors or flooded with
water, return it to a service center.
•Do not pull the machine by the cord, do not 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.
•Extension cords must be 12 gauge and no longer than 15 m. Replace the cord or unplug immediately if
the ground prong becomes damaged.
•Never fill the tank with water above 54ºC.
•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.
•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 MX 307 H 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. 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 10 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. The vacuum motors and the pump do not
require any scheduled maintenance; however, the vacuum motors may require replacement
brushes after 1000 - 1500 hours. 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.

OPERATION
1Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2Fill the solution tank with warm water. Using warm water may be a benefit in cleaning
effectiveness, but do not use hot water (above 54°C / 130°F+) in the tank. Add liquid
cleaning solution with a pH value of between 6 and 10. High pH detergents and/or acid rinses
will accelerate the wear of the seals and will void the warranty.
3Plug in the power cords. Turn the Heat switch on.
4Attach the spray hose to the solution quick disconnect on the front of the machine and attach
the vacuum hose to the hose barb on the recovery tank. Attach the other ends of the hoses
to the cleaning tool.
5Allow the heat exchanger two minutes to reach operating temperature.
6Turn on the pump. Turn on the vacuum. NOTE: the pump has a built in pressure switch; the
pump runs only while you are spraying.
7Begin cleaning using the correct hoses and tool.
8Use defoamer in the recovery tank or on the carpet any time foaming occurs, to prevent
motor damage.
9Monitor the water level in the solution tank. Do not let the pump run dry.
10When the solution tank gets low, turn off the pump, fill the solution tank, empty and clean the
recovery tank.
11When finished with the job, remove any unused solution from the solution tank, and run a
fewgallons of clean water through the system to rinse out any detergent.
12Empty and clean the recovery tank.
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 happens 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.
CAUTION!
To avoid vacuum motor damage, always make sure the float filter is clean and the ball can travel
freely prior to using the machine. And always use a defoamer when foaming occurs.
CAUTION! If water or foam comes out of the
vacuum exhaust, turn the machine off immediately
