GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instruc-

tionslistedbelowmayresultinelectricshock,fire,and/orseriousinjury.

SAVETHESE INSTRUCTIONS

Work Area

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

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.

3. Keep bystanders, children, animals 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. 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.

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

will increase the risk of electric shock.

6. 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.

7. 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.

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 immediately. Damaged

Power Cords increase the risk of electric shock.

Personal Safety

9. 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.

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.

SKU 90385 For technical questions, please call 1-800-444-3353. Page 4

14. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety

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

Tool Use and Care

15. Use clamps (not included) or other practical ways to secure and support the

workpiece to a stable platform. Holding the work by hand or against your body is

unstable and may lead to loss of control.

16. 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.

17. 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.

18. 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.

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

dangerous in the hands of untrained users.

20. 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.

21. 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.

22. 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

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

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

24. 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.

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 properoutlet installed

byaqualifiedelectrician.

GroundedTools: 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.)

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.)

Double InsulatedTools:Tools withTwo 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 on page 6.)

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

preceding illustration. (See Figure B on page 6.)
