Power ToolsOffer - More power, - Adaptability and - Dependability than ever before.

With enhanced tool performance- Safety issues also increased

Types of Power ToolsBased on the power source they use: Electric, Pneumatic, Liquid fuel, Hydraulic, and Powder-actuated.

General Safety rules for Power Tools Do not use power tools you are not trained on. Do not lift or carry power tools by their power cord. Keep power cords out of the paths of the power tool. Do not leave tools unattended.

General Safety rules for Cont. Power Tools5. Do not stand in water or wet surfaces when running a power tool6. Hold all power tools by the plastic hand grips or other nonconductive areas.7. Do not plug multiple electrical cords into a single outlet8. Do not use power tools or extension cords with a missing prong9. Ground all tools unless double insulated

General Safety rules for Cont. Power Tools10. Be aware of all power lines, electrical circuits and water pipes that are not visible 11. Do not wear loose clothing, dangling objects or jewelry. Long hair must be restrained 12. All observers should be kept a safe distance from the work area

General Safety rules for Cont. Power Tools13. Keep cords and hoses away from heat, oil, and sharp edges.

14. Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits and cutters.

Abrasive-Wheel Tools1) Before an abrasive wheel is mounted, it should be inspected closely and sound or ring tested to ensure it is free of cracks or defectsPowered abrasive grinding, cutting, polishing and wire buffing wheels create special safety problems because they can throw off flying fragments.2) To test wheels, tap them with a light non-metallic instrument. If they sound cracked or dead do not use them; they could fly apartPower Tools

Abrasive-Wheel Tools cont.Always use the right wheel or cup for the job you are performing. Be sure to match the RPM Rating with the tool. Finally, pay close attention to any special warnings, that the manufacturer may offer, such as do not use in wet or high-moisture conditions. Power Tools

Circular Saws 1) Always wear safety goggles or safety glasses with side shields2) Use a dust mask, especially when cutting treated woods 3) Wear hearing protection, especially during extended periods of operation

Circular Saws cont. .4) Use sharp blades, dull blades cause binding, stalling and possible kickbacks5) Use the correct blade for the job6) Ensure the blade guard is in working order, never remove it or tie it back7) Avoid cutting small pieces that cant be properly secured or the saw shoe cant properly rest

Drills Be sure the chuck is securely tightened to the spindle Tighten the bit securely and remove the chuck key Always hold or brace the tool securely and use any auxiliary handles if provided Dont force a drill. Apply only enough pressure for the bit to do the cutting

Miter / Chop Saws Because of the saws downward cutting motion, be sure to keep hands and fingers out of the blades path Be sure all guards are in place and working Ensure that the recommended size and RPM blades are being used
