use. Many accidents are caused by poorly maintained power tools. f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g ) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. h ) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations. 5) Service a ) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Additional Safety Rules for Tuckpointing • Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation. • The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. • The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. • The arbor size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbor holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control. • The shroud must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The shroud helps to protect operator from broken wheel fragments and accidental contact with wheel. • Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and shock the operator. • Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times. • Do not use a damaged accessory. Before each use inspect the accessory such as diamond wheel for chips and cracks, backing pad for cracks, tear or English excess wear. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time. • DO NOT grind or cut metal with this shroud. • Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. • Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback. • Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory. • Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. • Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body. • Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. • Do not operate the power tool near flammable materials. Sparks could ignite these materials. • Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. • DO NOT use bonded abrasive wheels. Only use Diamond coated Type 1 wheels. • ALWAYS use with a dust collector. Dust collector must provide at least 150 cubic feet per minute (cfm) of airflow and have a filter with 99% or greater efficiency for respirable particulate and a cyclonic pre-separator or filter-cleaning mechanism. • Operate and maintain tool in accordance with manufacturer's instructions to minimize dust emissions. WARNING: When not in use, place grinder on a stable surface where it will not move inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury may result. 3
