HOW TO USE MM TORQUE WRENCHES MM Torque wrenches are used in various operations where proper torquing of nuts, bolts and other fasteners is critical. Such operations include assembly and inspection of gear trains and bearings, setting of clutches and brakes, maintenance, repair, overhaul and experimental work. Mr. John should try with a crow Bar-Not a torque wrench. Always work with clean threads that are free of corrosion. It is important to follow the product manufacturer's instructions for specific torque loadings - particularly whether recommendations are for dry, oiled or plated threads, and other instructions which apply to a particular tool. Avoid over tightening a nut or bolt with a conventional wrench before applying a torque wrench. When not in use, the adjustable type wrench should be set to the lowest torque. ABUSE/MISUSE A Torque wrench is a precision instrument and should not be roughly handled. Never use it as a hammer, a pry or as a conventional wrench-use it only as a torque tool. Avoid dropping. When using adjustable wrenches do not over torque by applying torque past the release point. At low torque setting, the "click" Signal might be very soft. Learn the feel of the release, rather than relying on the sound. Read torque values on indicating torque wrenches by looking at the dial at 90º to its surface (this eliminates parallax error). If this is difficult to do, compensate by observing how much the apparent scale readings change when viewing from different angles. MM torque wrenches operate accurately when they are held by their designated grips. Cheater bars should never be used unless specifically permitted (or supplied) by the wrench manufacturer. MM torque wrenches are manufactured to the highest quality standard and subject to rigorous quality control and inspection procedures
