WORK AREA
1.
2.
Keep your work area clean and well lit. Cluttered and dark work areas
invite accidents.
Do not operate the Sump Pump in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Electrical equipment creates
sparks which may ignite the dust or fumes.
3.
1.
Keep bystanders, children, and visitors away while operating the Sump
Pump. Distractions can cause you to lose control.
ELECTRICAL SAFETY
Grounded tools must be plugged into a GFCI (Ground Fault Circuit
Interrupter) 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.
3.
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.
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.
PERSONAL SAFETY
1.
2.
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.
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.

5.
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.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the Sump Pump in unexpected
situations.
Always wear eye protection. Wear ANSI approved safety impact
goggles and nonskid rubber boots. A hard hat must be used for
appropriate conditions.
TOOL USE AND CARE
1.
2.
3.
Do not force the Sump Pump. Use the correct Pump for your application.
The correct Pump will do the job better and safer at the rate for which it is
designed.
Do not use the Sump Pump if the electrical circuit system does not turn it
on or off. Any electrical circuit system that cannot be controlled is dangerous
and must be repaired or replaced.
Turn off the electric power to the outlet supplying power to the Sump Pump
and disconnect the Pump’s Power Plug from the outlet before making any
adjustments, changing accessories, or storing the Sump Pump. Such
preventive safety measures reduce the risk of starting the tool accidentally.
4.
5.
Store idle tools and equipment out of reach of children and other untrained
persons. Tools and equipment are dangerous in the hands of untrained users.
Maintain the Sump Pump with care. Keep the Pump clean. Properly
maintained Sump Pump equipment is easier to control. Do not use damaged
equipment. Tag damaged equipment “Do not use” until repaired.
6.
7.
Check for misalignment or binding of moving parts, broken parts, and any
other condition that may affect the Sump Pump’s operation. If damaged,
have the Pump serviced before using. Many accidents are caused by poorly
maintained tools and equipment.
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 Sump Pump.

SERVICE
1.
2.
Sump Pump 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 the Sump Pump, 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.
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 away from the user, reducing the risk of
electric shock. (See Figure A, next page.)
2.
3.
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.)
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should resemble those in Figure A.
