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.
Keep work area clean. Cluttered areas invite injuries.
2.
Observe work area conditions. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.
3.
Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, or extension cords.
4.
Store idle equipment. Always lock up tools and keep out of reach of children.
5.
Do not force Pump. It will do the job better and more safely at the rate for which it
was intended. Do not use inappropriate attachments in an attempt to exceed the
Pump capacity.
6.
Use the right Pump for the job. Do not attempt to force a small Pump or attachment
to do the work of a larger industrial Pump. There are certain applications for which this
Pump was designed. Do not modify this Pump and do not use this Pump for a
purpose for which it was not intended.
7.
Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.
8.

9.
Do not overreach. Keep proper footing and balance at all times. Do not reach over
or across running machines.
10. Maintain Pump with care. Inspect tool cords periodically and, if damaged, have
them repaired by an authorized technician.
11. Avoid unintentional starting. Dry running of the Pump causes excess wear.
12. Stay alert. Watch what you are doing, use common sense. Do not operate any Pump
when you are tired.
13. Check for damaged parts. Before using any Pump, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function.
14. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures. It is strongly recommended that
this Pump be plugged into a Ground Fault Circuit Interrupter (GFCI). Have a qualified
electrician install the GCFI. To avoid electrical shock, no person or animal should
be in contact with the water being pumped. Never walk on wet or damp area
when pump is running in the same room.
15. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty.
16. Do not operate Pump 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 Pump.
17. Use proper size and type extension cord. If an extension cord is required, it must
be of the proper size and type to supply the correct current to the tool without heating
up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the tool. This tool requires use of an extension cord of 0 to 10 amps
capability (up to 50 feet), with wire size rated at 14 AWG. Longer extension cords
require larger size wire. If you are using the tool outdoors, use an extension cord
rated for outdoor use. (signified by “WA” on the jacket).
18. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician.
19. Do not pump hazardous materials. Do not pump explosive or flammable materials
such as Fuel Oil, Kerosene, Gasoline etc. Do not pump in close proximity to
flammable or explosive materials. Do not pump fats, oils, salt or waste water. This
Pump is designed to move clean or dirty water only. Do not pump hot liquid.
20. Water transfers in cycles. Do not attempt to manipulate the switch to keep Pump
running continuously. It is meant to shut off intermittently. Doing so will damage the
Pump.

Note: Performance of this Pump (if powered by line voltage) may vary depending on
variations in local line voltage. Extension cord usage may also affect Pump performance.
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 the parts listed on page 8 are included. If any parts
are missing or broken, please call Harbor Freight Tools at the number on the cover of this
manual as soon as possible.
Installation
Reminder: This Pump should be plugged into an outlet fitted with a Ground Fault Circuit
Interrupter (GFCI).
Note: Hose connection is covered on page 7.
1. Make sure the Pump rests on a flat, level, and solid foundation. Never operate on earth,
clay, sand, or gravel surfaces.
2. Never suspend the pump from the power cord or discharge pipe. You may firmly attach a
rope to the carry handle.
3. Keep the pump inlet openings, near the suction base, clear of debris.
4. Avoid installation in areas of extreme heat or cold.
5. If the piping you install runs in excess of ten feet, it is recommended you use a check valve
(not included) to prevent back flow, which could lead to rapid cycling. To avoid air locks in the
pump, drill a 1/8” hole, in the piping, between the check valve and the pump before you use
the pump.
Sump Installation (All instructions above apply)
1. The sump pit must have a minimum diameter of 11” and depth of 24”. If not, rapid cycling
and shortened pump life will occur.
2. Construct the pit of tile, plastic, concrete, or steel.
3. Set the pump on a brick or block slightly smaller than the pit. Fill the pit with clean 1” stones
to surround the lower half of the pump, and keep it stable. The stones should be large enough
to not clog any of the inlets.
4. Test pump (see Operation on page 5).
5. Install a sump cover (not included) to protect the pump from falling debris.

Operation
Float Switch Adjustment
The Float Switch - see Figure B, page 7, The pump will maintain a water level of approximately 2” above the base. When the water level drops below 2”, the Pump shuts off.
Warning: Do not run the pump dry. It will increase wear to the unit and possibly cause seal
damage.
Note: This pump has a built-in thermal protector for the motor, which automatically shuts it off
to avoid overheating. After it cools, it will cycle back on. Wait for the cyle to continue. Do not
try to turn on the pump manually after it has cut-off.
1. Plug unit into an outlet fitted with a Ground Fault Circuit Interrupter (GFCI).
2. The pump will automatically turn on when the water level, or the sump, has filled to approximately 2” above the base. It will stop when the water level drops below 2”. It will continue
to recycle thereafter.
3. Check that the discharge water travels several feet from the foundation.
Note: If air bubbles are spotted around the handle or pressure switch, this is normal. It is
trapped air escaping from the unit. This pump is equipped with a de-aerating device which
removes air locks in the pump. Also, if the the water level drops below the Vent Valve (#4Feature Listing, page 7), some water might purge from the pump from the Vent Valve. This
is normal. More on air escape covered in Troubleshooting.
Maintenance
Part numbers refer to the Parts List on page 8.
This pump motor is virtually maintenance free.
1. Any repair or replacement of parts should be performed by a qualified service technician.
Always unplug the electrical cord before performing maintenance.
2. Inlets should be inspected periodically and any debris which clogs them should be removed (Before performing inlet cleaning, disconnect the pump from the outlet).
3. Periodically clean the Base (#18). Remove the Screws (#19) from the Base (#18) and
remove any dirt or debris. Replace Base.
Troubleshooting
Problem 1 Pump runs but doesn’t deliver water.
Cause: Air cannot escape.
