IMPORTANT SAFETY INSTRUCTIONS
THIS MACHINE IS AN ELECTRICAL APPLIANCE. CARE MUST BE
TAKEN TO REDUCE THE RISK OF ELECTRICAL SHOCK.
READ AND UNDERSTAND ALL INSTRUCTIONS BEFORE OPERATING.
To reduce the risk of property damage or injury, repairs to electrical systems should only be
performed by experienced technicians. Contact your distributor for assistance. Unplug machine
power cord from outlet before performing any repairs on the extractor.
This machine shall be grounded while in use to protect the operator from electric shock and is
provided with a three-conductor cord and a three-contact grounding type attachment plug to fit the
proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the
grounding wire. Never connect this wire to other than the grounding pin of the attachment plug.
DO NOT use a plug adapter with this machine.
The power cords supplied with this machine are properly sized to handle the electrical load of this
machine and properly grounded as described above. Any extension cords used with this machine must
be similarly sized with an equal or greater load rating and grounded to assure safe operation. A properly
sized or rated GFCI protected cord can be used for additional protection.
DO NOT use the Spot Extractor outdoors, in standing water or on wet surfaces. Do not store in wet
conditions. If extractor is leaking, unplug machine power cords from outlets before approaching or
touching machine.
DO NOT unplug power cord by pulling on the cord. Grasp the plug end when unplugging the cord.
Do not pull the extractor by the cord. If cord or plug is damaged, do not use cord. Replace with new
cord or repair as needed before use.
An overloaded circuit may not always trip circuit breaker. Reduced voltage to a machine on an
overloaded circuit will prevent components from operating properly.
THIS MACHINE MUST BE PROTECTED FROM
CONDITIONS WHICH MAY DAMAGE THE PUMP, TANK,
HOSES AND OTHER COMPONENTS.
Freezing of water in this machine will cause serious damage. The Spot Extractor, solution hoses, and
tools must be protected from freezing temperature. Store, transport, and use this equipment only in
temperatures well above freezing. (32ºF or 0ºC). If you suspect the unit has been frozen, do not plug in
or turn on machine until you are sure it has thawed completely.
If the equipment cannot be stored or transported in a warm environment, it can be guarded from
freezing by running an anti-freeze solution through the incoming water lines, solution pump, solution
lines, and tools.
o The anti-freeze solution must be completely flushed from the machine before it is returned to
service.
DO NOT use the Spot Extractor to pick up flammable or combustible materials or use in areas where
these materials may be present.
Solvent-based or water-based solutions containing solvents may damage the pump, hoses, and other
components. Do not assume chemical compatibility. Contact your distributor or Hydro-Force if you
have questions regarding the compatibility of your chemicals with the machine.
DO NOT clean with solutions that are at temperatures above 130ºF.
Rinse the solution tank, chemical system, and pump with fresh water after each day’s use.
DO NOT allow pump to run dry. Always maintain adequate solution level to supply solution pump.

High pressure hoses may rupture if worn or damaged. Do not use HP solution hoses if hose covering is
cut, bulging, or otherwise damaged. Examine HP solution hoses daily and replace or repair hoses as
needed.
Use defoamer to eliminate foam build-up during cleaning and prevent foam/moisture from entering
vacuums.
