easily felt, so there is no doubt when the torque processis complete.Manufacturers' and technical manuals generallyspecify the amount of torque to be applied. Use thewrench properly in accordance with the manufacturer'sinstructions.You should use a torque wrench that reads aboutmid range for the amount of torque to be applied. BESURE THAT THE TORQUE WRENCH HAS BEENCALIBRATED BEFORE YOU USE IT. Rememberthat the accuracy of torque measuring is determinedwith how the threads are cut and the cleanliness of thethreads. Make sure you inspect and clean the threads. Ifthe manufacturer specifies a thread lubricant, it must beused to obtain the most accurate torque reading. Whenusing the deflecting beam or dial indicating wrenches,you should hold the torque at the desired value until thereading is steady.The torque wrench is a precision tool. It has atorque indicating handle and appropriate adapters orattachments (fig. 1-2, view E). It measures the amountof turning or twisting force applied to a nut or bolt ininch or foot-pounds. Certain aircraft hoisting slingsrequire torque values applied to successfully hoist theaircraft. For specific instructions, you should refer toNAVWEPS 17-1-108.CARE OF HAND TOOLSTools are expensive and vital equipment. When theneed for their use arises, common sense plus a littlepreventive maintenance prolongs their usefulness. Thefollowing precautions for the care of tools should beobserved:1.Clean tools after each use. Oily, dirty, andgreasy tools are slippery and dangerous to use.2.NEVER hammer with a wrench.3.NEVER leave tools scattered about. When theyare not in use, stow them neatly on racks or intoolboxes.4.Applying a light film of oil after cleaning canprevent 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 ofmetals should you avoid cutting?a.b.Q3.How can you prevent rust from building up onhand tools?PORTABLE POWER TOOLSLEARNINGOBJECTIVES:Identifythedifferent types of power tools. Describe theuses of different types of power tools.ABH's have a frequent requirement for the use ofportable power tools in the maintenance of assignedareas that are exposed to the weather. A power tool,when used properly and efficiently, is an enormous timesaver, especially when a large painted or rusted surfacerequires scaling and preservation. Before using electricportable tools, you should be sure the proper voltage issupplied.Thisinformationcanbefoundonthenameplate, which is permanently attached to the tool.Electric tools of all types used in the Navy are requiredto have an up to date electrical safety tag and properground capability. The tool should be provided with aground lead that connects the tool casing to the ship'sstructure. If doubt exists that a good ground has beenestablished, you should request the services of anElectrician's Mate to check it out before applyingpower to the tool. NEVER VARY the manufacturersrecommended voltage. SAFETY IS PARAMOUNT.
