easily felt, so there is no doubt when the torque process is complete. Manufacturers' and technical manuals generally specify the amount of torque to be applied. Use the wrench properly in accordance with the manufacturer's instructions. You should use a torque wrench that reads about mid range for the amount of torque to be applied. BE SURE THAT THE TORQUE WRENCH HAS BEEN CALIBRATED BEFORE YOU USE IT. Remember that the accuracy of torque measuring is determined with how the threads are cut and the cleanliness of the threads. Make sure you inspect and clean the threads. If the manufacturer specifies a thread lubricant, it must be used to obtain the most accurate torque reading. When using the deflecting beam or dial indicating wrenches, you should hold the torque at the desired value until the reading is steady. The torque wrench is a precision tool. It has a torque indicating handle and appropriate adapters or attachments (fig. 1-2, view E). It measures the amount of turning or twisting force applied to a nut or bolt in inch or foot-pounds. Certain aircraft hoisting slings require torque values applied to successfully hoist the aircraft. For specific instructions, you should refer to NAVWEPS 17-1-108. CARE OF HAND TOOLS Tools are expensive and vital equipment. When the need for their use arises, common sense plus a little preventive maintenance prolongs their usefulness. The following precautions for the care of tools should be observed: 1. Clean tools after each use. Oily, dirty, and greasy tools are slippery and dangerous to use. 2. NEVER hammer with a wrench. 3. NEVER leave tools scattered about. When they are not in use, stow them neatly on racks or in toolboxes. 4. Applying a light film of oil after cleaning can prevent rust on tools. 5. INVENTORY tools after use to prevent loss. Q1. What pliers are designed for cutting? Q2. When using bolt cutters, what two types of metals should you avoid cutting? a. b. Q3. How can you prevent rust from building up on hand tools? PORTABLE POWER TOOLS LEARNING OBJECTIVES: Identify the different types of power tools. Describe the uses of different types of power tools. ABH's have a frequent requirement for the use of portable power tools in the maintenance of assigned areas that are exposed to the weather. A power tool, when used properly and efficiently, is an enormous time saver, especially when a large painted or rusted surface requires scaling and preservation. Before using electric portable tools, you should be sure the proper voltage is supplied. This information can be found on the nameplate, which is permanently attached to the tool. Electric tools of all types used in the Navy are required to have an up to date electrical safety tag and proper ground capability. The tool should be provided with a ground lead that connects the tool casing to the ship's structure. If doubt exists that a good ground has been established, you should request the services of an Electrician's Mate to check it out before applying power to the tool. NEVER VARY the manufacturers recommended voltage. SAFETY IS PARAMOUNT.
