Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Avoid pump damage. Do not operate dry. Never lift or transport the pump by the
power cable or float switch cable.
2. Do not pump certain liquids. Do not pump gasoline, hydrocarbons, fuel oil,
kerosene, fats, salt or waste water, or chemical agents. Do not pump hot liquids.
3. Avoid fire or explosion. Do not pump in close proximity to flammable or explosive
materials.
4. Avoid working alone. If an accident happens, an assistant can bring help.
5. Avoid electrical shock. If the submersible pump is to be installed in a location
where a breakdown or fault could cause injury to persons, or damage to objects, the
power source must utilize a Ground Fault Circuit Interrupter (GFCI). This device will
immediately shut down power in case of a short circuit. This device must be tested
periodically. No persons should be in contact with the water being pumped.
6. Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, or extension cords.
7. Store idle equipment. When not in use, tools must be stored in a dry location to
inhibit rust. Always lock up tools and keep out of reach of children.
REV 07/06

8. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
9. Use eye and ear protection. Always wear ANSI approved impact safety goggles.
10. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across electrical cables or frames.
11. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
12. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified technician.
Do not use the tool if any switch does not turn On and Off properly.
13. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
14. Use proper power outlet. This pump has a three prong plug. The third prong (round)
is the ground. Plug the pump cord only into a three-prong, Ground Fault Circuit
Interrupter receptacle. Cutting off the ground prong will result in a safety hazard and
void the warranty.
15. Using Extension Cords. An extension cord up to 50 feet must have a wire size
of 18 AWG; up to 100 feet must have a wire size of 16 AWG. Do not submerge
extension cords or make contact with water. Note: Do not make the extension cord
connection underwater.
16. Use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this tool
was designed. Do not modify this tool and do not use this tool for a purpose for which
it was not intended.
17. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
18. Pacemaker safety warning. People with pacemakers should consult with their
physician(s) before using this product; operation of equipment in close proximity to a
heart pacemaker could cause interference or failure of the pacemaker.
Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood
by the operator that common sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.

Unpacking
When unpacking, check to make sure all parts are included. Refer to the parts list and as-
sembly diagram on page 7 and 8. If any parts are missing or broken, please call Harbor
Freight Tools at the number on the cover of this manual.
Operation
1. Connect drain hose to the Universal Adapter (47) discharge fitting. This hose should
be long enough to drain away from the reservoir being pumped. See installation
examples on the next page.
2. If the pump needs to be lowered into a pool or other deep reservoir, attach a rope to
the pump handle and lower into position. Never suspend the pump from the power
cord or discharge pipe.
The pump should rest on a flat, level, and solid foundation. Never operate on earth,
clay, sand, or gravel surfaces. Keep the pump inlet opening clear of debris. If the drain
piping runs in excess of 10 feet, it is recommended to use a check valve (not included)
to prevent back flow. To avoid air locks in the pump, drill an 1/8 inch hole in the piping,
between the check valve and the pump. Refer to the illustration on the next page.
Warning: Never use the line cord to carry the pump. Do not run the pump dry. It will
increase wear to the unit and cause possible seal damage.
3. Connect the Power Cable to the Ground Fault Interrupter receptacle to begin
pumping.
Caution:The Float Switch must be floating in water for the pump to operate. It is meant
to shut off intermittently. Do not attempt to manipulate the switch to keep the pump
running continuously. Doing so will damage the pump.
Warning: Never allow the power cord or extension cord connection (if used) to come
in contact with ground water.
Note: Performance of this pump may vary depending on variations in local line voltage.
Extension cord usage may also affect tool performance.
