GENERAL SAFETY RULES

WARNING:

Read and understand all instructions. Failure to fol- low all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

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

Do not operate power tools in explosive atmo- spheres, such as in the presence of flammable liquids, gases, or dust. Power tools may create sparks which may ignite the dust or fumes.

Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

Double insulated tools are equipped with a po- larized 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 insu-

lation 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, ranges, and refrigera- tors. There is an increased risk of electric shock if your body is grounded.

Don’t expose power tools to rain or wet condi- tions. Water entering a power tool will increase the risk of electric shock.

Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immedi- ately. Damaged cords increase the risk of electric shock.

When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inat- tention 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, cloth- ing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in mov- ing parts or drawn into air vents.

Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on, invites accidents.

Remove adjusting keys or wrenches before turn- ing the tool on. A wrench or a key that is left at- tached to a rotating part of the tool may result in personal injury.

Do not overreach. Keep proper footing and bal- ance at all times. Proper footing and balance en- ables better control of the tool in unexpected situa- tions. Do not use on a ladder or unstable support.

Use safety equipment. Always wear eye protec- tion. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate con- ditions.

TOOL USE AND CARE

Use clamps or other practical way to secure and support the workpiece to a stable platform. Hold- ing the work by hand or against your body is un- stable and may lead to loss of control.

Do not force 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 tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety mea- sures reduce the risk of starting the tool acciden- tally.

Store idle tools out of the 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 maintained tools with sharp cutting edges are less likely to bind and are easier to control.

Check for misalignment or binding of moving parts, breakage of parts, and any other condi- tion that may affect the tool’s operation. If dam- aged, 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 hazard- ous when used on another tool.
