ELECTRICAL SAFETY

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 malfunc-

tion 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 immediately. Dam-

aged Power Cords increase the risk of electric shock.

PERSONAL SAFETY

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

ing 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.

Avoid accidental starting. Be sure the ON/OFF Knob (86) is off before plug-

ging in. Plugging in power tools with the ON/OFF Knob on, invites accidents.

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.

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.

Use safety equipment. Always wear eye protection. Always wear

ANSI approved safety impact goggles when using this product. Hearing

protection must be used for appropriate conditions.

TOOL USE AND CARE

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.

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.

Do not use the power tool if the ON/OFF Knob (86) does not turn it on or off.

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

be replaced.

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.

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

are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean. Properly main-

tained 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.

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.

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

Tool 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 a tool, use only identical replacement parts. Follow in-

structions 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

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 B, 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 B.)

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 B.)
