WORK AREA
1.
2.
Keep your work area clean and well lit. Cluttered and dark work areas invite
accidents.
Do not operate power tools in explosive atmospheres,such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
3.
1.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
Grounded tools must be plugged into an outlet properly installed and grounded
in accordance with all codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. If the tool should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.
2.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
3.
4.
Do not expose the Motor to rain or wet conditions. Water entering the Motor
will increase the risk of electric shock.
Do not abuse the Power Cord. Never use the Power Cord to pull the Plug from
an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving
parts. Replace damaged Power Cords immediately. Damaged Power Cords
increase the risk of electric shock.
5.
1.
When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the
risk of electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operating
a power tool. Do not use a power tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.

3.
4.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
Avoid accidental starting. Be sure the circuit supplying electrical power is off
before plugging in. Plugging in a Sump Pump with the electrical circuit on invites
accidents.
Remove adjusting keys or wrenches before turning the power tool on. A wrench
or a key that is left attached to a moving part of the power tool may result in personal
injury.
5.
6.
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
Always wear eye protection. Wear ANSI approved safety impact
goggles and non-skid rubber boots. A hard hat must be used for
appropriate conditions. Wearing work pants and work shirt are
recommended.
TOOL USE AND CARE
1.
2.
Do not force the tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
Do not use the power tool if the Automatic Switch (3) does not turn it on or off.
Any tool that cannot be controlled with an Automatic Switch is dangerous and must
be replaced.
3.
Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
4.
5.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep tools clean. Properly maintained tools are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
6.
Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are caused by poorly main tained
tools.

7.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
1.
2.
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether the
outlet is properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the
tool if the power cord or plug is damaged. If damaged, have it repaired by
a service facility before use. If the plug will not fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
2.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity aways from the user, reducing the risk of
electric shock. (See Figure A, next page.)
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure A.)

ASSEMBLY AND OPERATING INSTRUCTIONS
NOTE: For additional information regarding the parts listed in the following pages, refer
to the Assembly Diagram on page 14.
1.
If necessary, have a certified electrician install (within six feet of where the Sump
Pump will be located) a 115 volt, grounded, electrical outlet that is dedicated only
to the Pump. Any outlet must be above the water line.
1.
WARNING! Always make sure the Sump Pump is unplugged from its
electrical outlet prior to assembling the unit, unclogging the unit, or making any
adjustments to the unit.
2.
3.
Snap the Hook (20) midway onto the Support (21). (See Figure D.)
Insert the threaded end of the Float Rod (10) downward through the eyelet in the
Hook (20). Then, screw on the Float (11). (See Figure D.)
4.
Remove the Upper Rubber Stop on the automatic Switch Arm (3) and insert the
top portion of the Float Rod (10) through the hole in the arm of the automatic
Switch (3). Then, replace the Upper Rubber Stop at least 1/2” from the end of
the Float Rod. (See Figure D.)
5.
6.
Set the Sump Pump in place, making sure the arm of the automatic Switch (3)
has adequate clearance and will not hang up on the pit wall. (See Figure D.)
NOTE: The size of the discharge outlet on the Impeller Case (22) is 1-1/4”

Do not attempt to reduce the discharge size below 1-1/4” as this will affect Pump
flow and performance. A Schedule 40 PVC 1-1/4” diameter Pipe is recom-
mended. (See Figure D.)
7.
Connect the 1-1/4” diameter Discharge Pipe to the Impeller Case (22) of the
Sump Pump. Make sure to hand tighten only. Over tightening may cause the
Impeller Case to crack. NOTE: Make sure the Discharge Pipe is secured to a
solid surface, with appropriate hardware (not included), to ensure the stability of

just above the floor to facilitate removal of the Sump Pump if necessary.
(See Figure D.)
NOTE: A Check Valve (not included) is recommended just above, or in place of,
the Union to prevent the backflow of water after each pump cycle. If a Check
Valve is used, a 1/8” diameter air bleed hole should be drilled through the Dis
charge Pipe just above the Impeller Case (22) to prevent pump “airlock”. A small
spray of water out of this hole is normal while pump is running. (See Figure D.)
10.
11.
Connect additional Discharge Pipe as needed to direct the discharge to the
desired location. The discharge should be kept as short as possible with
a minimum number of turns. NOTE: The maximum lift of the Pump is 17 feet.
Plug the Power Cord into the nearest 115 volt, grounded, electrical outlet while
making sure to form a “drip loop” in the Power Cord. (See Figure C.)
12.
13.
The Sump Pump is now ready for operation.
NOTE: Periodically, check to make sure all connections are tight and secure.
Also, make sure the Float Rod (10) moves freely.
