SAVE THESE INSTRUCTION

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, 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.

9.

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

10.

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.

11.

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.

12.

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.

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, nonskid 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 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.

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.

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, 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.

SPECIFIC SAFETY RULES FOR THIS PRODUCT

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 or product. 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 with Three Prong Plugs

This product has a three-prong plug as a feature to reduce the risk of electric shock.

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.)

Figure A Figure B

Double Insulated Tools with Two Prong Plugs

4.

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. Never use with an extension cord unless plug can be fully inserted. Do not alter the plug.”

5.

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.)

6.

Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.)

EXTENSION CORDS

1.

Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.

2.

As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)

3.

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table

A.)

4.

When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.)

5.

If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)

6.

If you are using an extension cord outdoors, make sure it is marked with the suffix “W-

A” (“W” in Canada) to indicate it is acceptable for outdoor use.

7.

Make sure your extension cord is properly wired and in good electrical condition.

Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

8.

Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
