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.

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.
