Tool SafetyHand Tools1. Only tools that are in good condition shall be used in operations. They shall be properly cleanedafter use, and cutting tools shall be kept sharp.2. Do not carry tools in your pockets. They shall be carried in a tool kit or in hand in such a manneras to prevent injury by stabbing, dropping, pinching, and the like. Some rules for specific toolsfollow.3. Hammers: Before using a hammer, check the head for a tight fit. If the hammer has a crackedhead or a loose or cracked handle, return it to the tool crib for replacement. Hammers that haveburrs, loose chips, or signs of mushrooming shall not be used.4. Wrenches: Use the correct wrench for the job to be done. Pull rather than push on the handle ofthe wrench. Do not place extensions on wrench handles for more leverage. Use the proper sizedwrench.5. Knives: Keep your hands and the knife handles clean, dry, and free of grease. Do not placeknives on shelves or table edges where they might fall. Keep the blade in a sheath when theknife is not in use.6. Pliers: Wear eye protection when using pliers to clip wire ends. Hold the wire and pliers so thatthe ends, when snipped, are directed towards the ground.7. Impact tools, such as drift pins, wedges, and chisels, shall be kept free of mushroomed heads.8. The wooden handles of tools shall be kept free of splinters or cracks and shall be kept tight inthe tool.9. Appropriate personal protective equipment should be worn due to hazards that may beencountered while using portable power tools and hand tools.10. Floors should be kept as clean and dry as possible to prevent accidental slips with or arounddangerous hand tools.11. Hand tools are non-powered. They include anything from axes to wrenches. The greatesthazards posed by hand tools result from misuse and improper maintenance.The greatest hazards posed by hand tools result from misuse and improper maintenance.9
Tool SafetyAngle GrinderDO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence togrinder safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.1. Always use safety glasses or goggles.2. Obtain permission from instructor before using the saw.3. Always use proper guard with grinding wheel. A guard protects operator from broken wheelfragments.4. Accessories must be rated for at least the speed recommended on that may affect the toolsoperation. If damaged, have the tool serviced before using. Many accidents are caused by poorlymaintained tools.SPECIFIC SAFETY RULES5. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool maycontact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of thetool “live” and shock the operator.6. When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels.7. Ordinary sun glasses are NOT safety glasses.9. Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheelimmediately. Run the tool (with guard) at no load for about a minute, holding tool away from others. Ifwheel is flawed, it will likely separate during this test.10. Use only flanges specified for this tool.11. Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut.Damage to these parts could result in wheel breakage.12. NEVER use tool with wood cutting blades or other saw blades. Such blades when used on a grinderfrequently kick and cause loss of control leading to personal injury.13. Hold the tool firmly.14. Keep hands away from rotating parts.15. Make sure cord is clear of wheel. Do not wrap cord around your arm or wrist. If control of tool is lost,cord may become wrapped around you and cause personal injury.16. Make sure the wheel is not contacting the work piece before the switch is turned on.17. Before using the tool on an actual work piece, let it run for a while. Watch for vibration or wobblingthat could indicate poor installation or a poorly balanced wheel.18. Use the specified surface of the wheel to perform the grinding.19. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons orflammable materials.20. Do not leave the tool running. Operate the tool only when hand-held.21. Do not touch the work piece immediately after operation; it may be extremely hot and could burnyour skin.23. ALWAYS wear proper apparel including long sleeve shirts, leather gloves and shop aprons to protectskin from contact with hot grindings.24. Use of this tool to grind or sand some products, paints and wood could expose user to dustcontaining hazardous substances. Use appropriate respiratory protection.10
25 Always be sure that the tool is switched off and unplugged before adjusting or checking function onthe tool.SAVE THESE INSTRUCTIONS WARNING: MISUSE or failure to follow the safety rules stated in thisinstruction manual may cause serious personal injury.CAUTION: Never actuate the shaft lock when the spindle is moving. The tool may be damaged. Press the shaftlock to prevent spindle rotation when installing or removing accessories Before plugging in the tool, always check to see that the switch actuates properly and returns to the“OFF” position when the rear of the slide switch is depressed. It should never be necessary to force the tool. The weight of the tool applies adequate pressure.Forcing and excessive pressure could cause dangerous wheel breakage. ALWAYS replace wheel if tool is dropped while grinding NEVER bang or hit grinding disc or wheel onto work. Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This cancause loss of control and kickback. NEVER use tool with wood cutting blades and other saw blades.Such blades when used on a grinder frequently kick and cause loss of control leading to personalinjury. After operation, always switch off the tool and wait until the wheel has come to a complete stopbefore putting the tool down.ALWAYS hold the tool firmly with one hand on housing and the other on the side handle. Turn thetool on and then apply the wheel or disc to the work piece. In general, keep the edge of the wheel ordisc at an angle of about 15 degrees to the work piece surface. During the break-in period with a newwheel, do not work the grinder in the B direction or it will cut into the work piece. Once the edge ofthe wheel has been rounded off by use, the wheel may not cut well in two directions11
Tool SafetyCircular SawSPECIFIC SAFETY RULESDO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence tocircular saw safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personalinjury.Danger:1. Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, ormotor housing. If both hands are holding the saw, they cannot be cut by the blade.2. Do not reach underneath the work piece. The guard cannot protect you from the blade below thework piece. Do not attempt to remove cut material when blade is moving. Blades coast after turn off.Wait until blade stops before grasping cut material.CAUTION:3. Adjust the cutting depth to the thickness of the work piece. Less than a full tooth of the blade teethshould be visible below the work piece.4. Never hold piece being cut in your hands or across your leg. Secure the work piece to stable platform.It is important to support the work properly to minimize body exposure, blade binding, or loss ofcontrol. A typical illustration of proper hand support, work piece support, and supply cord routing (ifapplicable).5. Hold power tool by insulated gripping surfaces when performing an operation where the cutting toolmay contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal partsof the power tool "live" and shock the operator.6. When ripping always use a rip fence or straight edge guide. This improves the accuracy cut andreduces the chance of blade binding.7. Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that donot match the mounting hardware of the saw will run eccentrically, causing loss of control.8. Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were speciallydesigned for your saw, for optimum performance and safety of operation.9. Causes and Operator Prevention of Kickback: kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolledsaw to lift up and out of the work piece toward the operator; when the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motorreaction drives the unit rapidly back toward the operator; if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can diginto the top surface of the wood causing the blade to climb out of the kerf and jump back toward theoperator.Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can beavoided by taking proper precautions as given below.Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces.Position your body to either side of the blade, but not in line with the blade. Kickback could cause the12
saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions aretaken. When blade is binding, or when interrupting a cut for any reason, release the trigger and holdthe saw motionless in the material until the blade comes to a complete stop. Never attempt toremove the saw from the work or pull the saw backward while the blade is in motion or kickbackmay occur. Investigate and take corrective actions to eliminate the cause of blade binding. When restarting a saw in the work piece, center the saw blade in the kerf and check that sawteeth are not engaged into the material. If saw blade is binding, it may walk up or kickback fromthe work piece as the saw is restarted. Support large panels to minimize the risk of blade pinching and kickback. Large panels tend tosag under their own weight. Supports must be placed under the panel on both sides, near theline of cut and near the edge of the panel. To minimize the risk of blade pinching and kickback, when cutting operation requires the restingof the saw on the work piece, the saw should be rested on the larger portion and the smallerpiece cut off. To avoid kickback, do support board or panel near the cut. Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerfcausing excessive friction, blade binding and kickback. Keep blade sharp and clean. Gum andwood pitch hardened on blades slows saw and increases potential for kickback. Keep bladeclean by first removing it from tool, then cleaning it with gum and pitch remover, hot water orkerosene. Never use gasoline. Blade depth and bevel adjusting locking levers must be tight and secure before making cut. Ifblade adjustment shifts while cutting, it may cause binding and kickback. Use extra caution when making a "plunge cut" into existing walls or other blind areas. Theprotru
