BM 1609929J64 12-05 12/12/05 4:07 PM Page 4 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 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. Regularily 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. ! 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 chemicallytreated 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-
