RULES FOR SAFE OPERATION
■Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
Service
■Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
■When servicing a tool, use only identical replace- ment parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.
Specific Safety Rules for Grinders
■Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments.
■Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury.
■Hold tool by insulated gripping surfaces when performing an operation where the tool may contact hidden wiring or its own cord. Contact with a ÒliveÓ wire will make exposed metal parts of the tool ÒliveÓ and shock the operator.
■Grinding wheel and guard must be securely attached as described in this operating manual before connecting the grinder to a power source.
■Grinding wheels must be stored in a dry place.
■Before attaching the grinding wheel, inspect it for visible defects. If cracked, chipped, or warped, do not install it.
■Do not overtighten the clamp nut on the grinding wheel. Excessive tightening can cause the wheel to crack during operation
■Make sure that the guard is in good condition and securely installed before operating grinder.
■Do not clamp the grinder in a vise or use as a fixed grinder.
■Never turn on the grinder with the grinding wheel or any rotating parts touching the workpiece.
■Use only grinding wheels in compliance with ANSI standard B7.1 and rated greater than 11,000 RPM.
■Do not use the grinder if the disc flange or clamp nut is missing or if the spindle is bent.
■Always hold the grinder securely with two hands while working and at all times when it is running.
■Never cover the air vents in the motor housing with your hands while operating the grinder.
■Hold the tool away from your body while it is running. Keep your hands away from the abrasive attachments.
■Dust and waste materials should not be allowed to build up in the workshop. Hot metal sparks could start a fire.
■Do not enlarge or alter the center hole of the grinding wheel as this could result in breaking it.
■Use only the normal grinder surface. Never use the side or upper surfaces for cutting.
■Keep the tool and its handle dry, clean, and free from oil and grease. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum- based products, or any strong solvents to clean your tool.
Additional Rules for Safe Operation
■Know your power tool. Read operator's manual care- fully. Learn its applications and limitations as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury.
■Always wear safety glasses with side shields. Everyday eyeglasses have only impact resistant lenses; they are NOT safety glasses.
■Protect your lungs. Wear a face or dust mask if the operation is dusty.
■Protect your hearing. Wear hearing protection during extended periods of operation.
■Inspect tool cords periodically and if damaged, have repaired at your nearest authorized service center. Stay constantly aware of cord location.
■Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center. Following this rule will reduce the risk of electric shock, fire, or serious injury.
■Do not abuse cord. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil and sharp edges. Following this rule will reduce the risk of electric shock or fire.
■Make sure your extension cord is in good condi- tion. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. A wire gage size (A.W.G.) of at least 16 is recommended for an extension cord 100 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
■Inspect for and remove all foreign objects from workpiece before grinding. Following this rule will reduce the risk of serious personal injury.
