Resumen del manual
To remove the socket, simply pull it off. 1. Socket 2. Anvil The proper fastening torque may differ depending upon the OPERATION kind or size of the bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures. Standard bolt N.m (ft.lbs) 200 M20 (3/4”) 0 0.5 1 1.5 (S) M20X50 (3/4” X 2”) M16X50 (5/8” X 2”) M12X50 (7/16” X 2”) M16 (5/8”) M12 (7/16”) Fastening time (144) 150 (108) 100 Proper fastening torque Fastening torque (72) 50 (36) High tensile bolt High tensile bolt (ft.lbs) 300 (217) 250 M16 (5/8”) (181) 200 M16X50 (5/8” X 2”) M12X50 (7/16” X 2”) 0 12345678 (S) Proper fastening torque Fastening torque (144) 150 (108) M12 (7/16”) 100 (72) 50 (36) Fastening time Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on and fasten for the proper fastening time. NOTE: • Hold the tool pointed straight at the bolt or nut. • Excessive fastening torque may damage the bolt/nut or socket. Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut. The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench. 1. Voltage Voltage drop will cause a reduction in the fastening torque. 2. Socket • Failure to use the correct size socket will cause a reduction in the fastening torque. • A worn socket ( wear on the hex end or square end ) will cause a reduction in the fastening torque. 3. Bolt • Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of bolt. • • 4. The use of the universal joint or the extension bar somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time. 5. The manner of holding the tool or the material of driving position to be fastened will affect the torque.
