WORK AREA

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.

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.

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.

1.

2.

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.

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

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.

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.

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

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.
