45. The outside diameter and the thickness of youraccessory must be within the capacity rating ofyour power tool. Incorrectly sized accessoriescannot be adequately guarded or controlled.6. Threaded mounting of accessories must matchthe grinder spindle thread. For accessoriesmounted by flanges, the arbour hole of theaccessory must fit the locating diameter of theflange. Accessories that do not match the mountinghardware of the power tool will run out of balance,vibrate excessively and may cause loss of control.7. Do not use a damaged accessory. Before eachuse inspect the accessory such as abrasivewheels for chips and cracks, backing pad forcracks, tear or excess wear, wire brush forloose or cracked wires. If power tool oraccessory is dropped, inspect for damage orinstall an undamaged accessory. Afterinspecting and installing an accessory,position yourself and bystanders away fromthe plane of the rotating accessory and runthe power tool at maximum no-load speed forone minute. Damaged accessories will normallybreak apart during this test time.8. Wear personal protective equipment.Depending on application, use face shield,safety goggles or safety glasses. Asappropriate, wear dust mask, hearingprotectors, gloves and workshop aproncapable of stopping small abrasive orworkpiece fragments. The eye protection mustbe capable of stopping flying debris generated byvarious operations . The dust mask or respiratormust be capable of filtrating particles generatedby your operation. Prolonged exposure to highintensity noise may cause hearing loss.9. Keep bystanders a safe distance away from workarea. Anyone entering the work area must wearpersonal protective equipment. Fragments ofworkpiece or of a broken accessory may fly away andcause injury beyond immediate area of operation.10. Hold the power tool by insulated grippingsurfaces only, when performing an operationwhere the cutting tool may contact hiddenwiring. Contact with a "live" wire will also makeexposed metal parts of the power tool "live" andcould give the operator an electric shock.11.

Using water or other liquid coolantsmay result in electrocution or shock.Kickback and Related WarningsKickback is a sudden reaction to a pinched or snaggedrotating wheel, backing pad, brush or any other accessory.Pinching or snagging causes rapid stalling of the rotatingaccessory which in turn causes the uncontrolled power toolto be forced in the direction opposite of the accessory’srotation at the point of the binding.For example, if an abrasive wheel is snagged orpinched by the workpiece, the edge of the wheel that isentering into the pinch point can dig into the surface ofthe material causing the wheel to climb out or kick out.The wheel may either jump toward or away from theoperator, depending on direction of the wheel’smovement at the point of pinching. Abrasive wheelsmay also break under these conditions.Kickback is the result of power tool misuse and/orincorrect operating procedures or conditions and can beavoided by taking proper precautions as given below.a) Maintain a firm grip on the power tool andposition your body and arm to allow you toresist kickback forces. Always use auxiliaryhandle, if provided, for maximum control overkickback or torque reaction during start-up.The operator can control torque reactions orkickback forces, if proper precautions are taken.b) Never place your hand near the rotatingaccessory. Accessory may kickback over your hand.c) Do not position your body in the area wherepower tool will move if kickback occurs.Kickback will propel the tool in direction oppositeto the wheel’s movement at the point of snagging.d) Use special care when working corners,sharp edges etc. Avoid bouncing and snaggingthe accessory. Corners, sharp edges or bouncinghave a tendency to snag the rotating accessoryand cause loss of control or kickback.e) Do not attach a saw chain woodcarvingblade or toothed saw blade. Such blades createfrequent kickback and loss of control.Safety Warnings Specific for Grinding and AbrasiveCutting-Off Operations:a) Use only wheel types that are recommendedfor your power tool and the specific guarddesigned for the selected wheel. Wheels forwhich the power tool was not designed cannot beadequately guarded and are unsafe.
