General Power Tool Safety Warnings
Read all safety
warnings and all instructions. Failure to follow the warnings and instruc- tions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or dust. Power tools cre- ate sparks which may ignite the dust or fumes.
Keep children
and bystanders away while operating a power tool. Distractions can cause you to lose control.
Do not operate
the power tool near flammable materials. Sparks could ignite these materials.
ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body
contact with earthed or grounded sur- faces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Do not abuse
the cord. Never use the cord for carry- ing, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operat-
ing a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operat- ing a
power tool in a damp location is unavoidable, use a residual current device (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
1.Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
2.Do not operate tool with damaged cord or plug.
•Have a damaged or worn power cord and/or strain relief replaced immediately.
•Do not attempt to repair power cord.
3.Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
4.Do not use an extension cord unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
