GENERAL SAFETY RULES

WARNING! Read all instructions

Failure to follow all instructions listed below may result in electric shock,

re, and/or serious injury. The term “power tool” in all of the warnings listed

below refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

SAVE THESE INSTRUCTIONS

WORK AREA

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

invite accidents.

Do not operate power tools in explosive atmospheres, such as in the2.

presence of ammable liquids, gases, or dust. Power tools create sparks

which may ignite the dust or fumes.

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

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

Grounded tools must be plugged into an outlet properly installed and1.

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 qualied 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.

Double insulated tools are equipped with a polarized plug (one blade is2.

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

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

not t, contact a qualied 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.

Avoid body contact with grounded surfaces such as pipes, radiators,3.

ranges, and refrigerators. There is an increased risk of electric shock if your

body is grounded.

Do not expose power tools to rain or wet conditions.4. Water entering a power

tool will increase the risk of electric shock.

Do not abuse the Power Cord.5. 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

Stay alert. Watch what you are doing, and use common sense when1.

operating a power tool. Do not use a power tool while tired or under the

inuence 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 long2.

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.3. Be sure the Power Switch is off before plugging

in. Plugging in power tools with the Power Switch on, invites accidents.

Remove adjusting keys or wrenches before turning the power tool on.4. A

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

in personal injury.

Page 4SKU 90589 For technical questions, please call 1-800-444-3353.

Do not overreach. Keep proper footing and balance at all times.5. Proper

footing and balance enables better control of the power tool in unexpected

situations.

Use safety equipment. Always wear eye protection.6. Dust mask, non-skid

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

conditions.

TOOL USE AND CARE

Do not force the tool. Use the correct tool for your application.1. 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 Power Switch does not turn it on or off.2.

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 any3.

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.4. Tools

are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean.5. 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.

Check for misalignment or binding of moving parts, breakage of parts,6.

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 your7.

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 qualied repair personnel. 1. Service

or maintenance performed by unqualied personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow2.

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.
