3. Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Protect others in the work area from

debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. 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 tools should electrically malfunction or

break down, grounding provides a low resistance path to carry electricity away

from the user.

5. Double insulated tools are equipped with a polarized plug (one blade is

wider than the other). This plug will fit in a polarized outlet only one way. If

the plug does not fit fully in the outlet, reverse the plug. If it still does not

fit, contact a qualified electrician to install a polarized outlet. Do not

change the plug in any way. Double insulation eliminates the need for the

three wire grounded power cord and grounded power supply system.

6. 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.

7. Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,

sharp edges, or moving parts. Replace damaged Power Cords immedi-

ately. Damaged Power Cords increase the risk of electric shock.

PERSONAL SAFETY

9. Stay alert. Watch what you are doing, and use common sense when oper-

ating a power tool. Do not use a power tool while tired or under the influ-

ence of drugs, alcohol, or medication. A moment of inattention while operat-

ing power tools may result in serious personal injury.

SKU 90234 PAGE 3

2. 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.

10. 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.

11. Avoid accidental starting. Be sure the Power Switch is off before plugging

in. Carrying power tools with your finger on the Power Switch, or plugging in

power tools with the Power Switch on, invites accidents.

12. Remove adjusting keys or wrenches before turning the power tool on. A

wrench or a key that is left attached to a rotating part of the power tool may result

in personal injury.

13. 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.

14. Use safety equipment. Always wear eye protection. Dust mask, non-skid

safety shoes, hard hat, or hearing protection must be used for appropriate

conditions.

TOOL USE AND CARE

15. 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.

16. Do not use the power tool if the Power Switch does not turn it on or off.

Any tool that cannot be controlled with the Power Switch is dangerous and must

be replaced.

17. 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.

18. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

19. Maintain tools with care. Keep cutting tools sharp and clean. Properly

maintained tools with a sharp cutting edge are less likely to bind and are easier

to control. Do not use a damaged tool. Tag damaged tools “Do not use” until

repaired.

SKU 90234 PAGE 4

20. 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

maintained tools.

21. 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

22. Tool service must be performed only by qualified repair personnel. Service

or maintenance performed by unqualified personnel could result in a risk of injury.

23. 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

SKU 90234 PAGE 5

WARNING!

Improperly connecting the grounding wire can result in the risk of electric

shock. Check with a qualfified 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 elec-

tric shock. (See Figure A, next page.)

2. 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.)

3. 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 look like those in the following illustration. (See Figure A.)

FIGURE A

SKU 90234 PAGE 6

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS

4. Tools marked “Double Insulated” do not require grounding. They have a special

double insulation system which satisfies OSHA requirements and complies with

the applicable standards of Underwriters Laboratories, Inc., the Canadian

Standard Association, and the National Electrical Code. (See Figure B.)

5. Double insulated tools may be used in either of the 120 volt outlets shown in the

following illustration. (See Figure B.)
