When using grinding wheel attachments, the guard must always be attached to the tool and positioned for maximum safety, so the least amount of wheel is exposed from the side the tool is being operated. 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. Grinding wheels or any other accessory must have a maximum safe operating speed greater than the “no load RPM” marked on the tool’s nameplate. Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. Always use auxiliary handle for maximum control over torque reaction or kick-back. Operation of the grinder without the side handle could cause loss of control of the -3 BM 1609929H54 08-06 8/3/06 11:44 AM Page 4 grinder, resulting in possible serious personal injury. Before using a grinder or installing a new wheel, inspect the grinding wheel for chips and cracks. Remove bad wheels immediately. Run the tool at no load for one minute, holding the tool in the direction away from people. Wheels with flaws will normally break apart during this time. Carefully handle both the tool and individual grinding wheels to avoid chipping or cracking. Install a new wheel if tool is dropped while grinding. Do not use a wheel that may be damaged. Fragments from a wheel that bursts during operation will fly away at great velocity possibly striking you or bystanders. Do not use grinding wheel that is larger than the maximum recommended size for your tool, or worn down damaged wheels from larger grinders. Wheels intended for large angle sander/grinders are not suitable for the high speed of a small angle sander/grinder, these wheels may easily burst and the fragments strike you or bystanders. Do not use depressed hub grinding wheels for cut-off operations. Depressed hub wheels or type 27 wheels are not intended for side loading and may shatter under overload. Do not use this tool with “Woodcarving” blade. Such blades create frequent kick-back and loss of control. Wear proper apparel while using a sander/grinder. Face shield or at least safety goggles, dust mask, leather gloves and shop apron capable of stopping small wheel or workpiece fragments. Position the cord clear of the spinning grinding wheel or any other sanding accessory. Do not wrap the cord around your arm or wrist. If you lose control and have the cord wrapped around your arm or wrist it may entrap you and cause injury. Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kick-back. Regularly clean the tool’s air vents by compressed air. Excessive accumulation of powdered metal inside the motor housing may cause electrical failures. Do not grind or sand near flammable materials. Sparks from the wheel could ignite these materials. This tool can be converted to a sander. When grinding is resumed the proper guard and wheel flanges MUST be reinstalled before proceeding with grinding. The guard must always be attached to the tool and positioned for maximum safety, so the least amount of wheel is exposed from the side the tool is being operated. The grinding wheel guard cannot be used for most sanding operations or for wire brushing. When sanding, do not use oversized sanding disc. Larger sanding disc will extend beyond the sanding pad causing snagging, tearing of the disc or kick-back. Extra paper extending beyond the sanding pad can also cause serious lacerations. When sanding chemically pressure treated lumber, paint that may be lead based, or any other materials that may contain carcinogens, use special precautions. A suitable breathing respirator must be worn by all personal entering the work area. Work area should be sealed by plastic sheeting and persons not protected should be kept out until work area is thoroughly cleaned. Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be discharged at high velocity during the “cleaning” action with these brushes and may become imbedded in your skin. !WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints, • Crystalline silica from bricks and cement and other masonry products, and • Arsenic and chromium from chemically- treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. -4 BM 1609929H54 08-06 8/3/06 11:...
