Description
Westward micrometer torque wrench is a precision instrument designed to accurately
measure torque. Other uses should be avoided. It should never be used to break loose
stubborn fasteners.
The self-contained torque limiting mechanism employs an exclusive, patented design that
minimizes friction, and is rugged and dependable. The precision made part are sealed so
dirt or liquids cannot easily affect the built-in accuracy of the mechanism. The wrench is not
affected by extreme changes of temperature.
Unpacking
After unpacking unit, make sure all parts are present. If any part is missing or damaged, do
not attempt to use the product. Contact customer service. Shipping damage claim must be
filed with carrier.

General Safety Information
Your torque wrench was calibrated and tested before leaving the factory and is guaranteed
to meet or exceed ASME B107.14 standard.
Because your torque wrench is a precision measuring instrument, it should be serviced
only where skilled men and special tools and equipment are available.
Do not continue pulling on the wrench after pre-set torque has
been reached. Pressure must be taken off the handle and the wrench allowed to
automatically reset itself.
Ratchet mechanism may slip or break if dirty, mismatched or if
worn parts are used. Ratchets that slip or break can cause injury.
Operation
1. To unlock the handle, hold the body
tube and pull the locking ring (A) back,
allowing the handle (B) to turn
clockwise or counterclockwise.
2. Set the desired torque by turning the
handle. For example, 85 Ft-Lb.
a. Pull the locking ring to adjust the torque.
b. Turn the handle until the zero graduation on minor scale lined up with the vertical
line and is even with 80 Ft-Lb graduation.
c. Turn the handle clockwise and set the minor scale to “five (5)”on the vertical line.
Now the torque is set at 85 Ft-Lb.
3. Release the locking ring to lock the handle.
4. Install the proper socket or attachment to the square drive and apply to the object
being torqued. Applying a stead pull to the center of handle, and stop pulling until you
hear a “Click”sound. The release is distinct and unmistakable. It can be felt as well
as heard. When pressure is removed from the handle, the torque wrench will
automatically reset itself.

USE OF EXTENSIONS AND ADAPTERS
When using an extension or adapter (increasing the effective length of the torque wrench),
the output torque value will change. To calculate the new torque output of the torque
wrench, use the following:
TW=Torque wrench scale reading,
TA=Torque exerted at the end of adapter
L=Distance between square drive and hand position
A=Length of adapter or extension
NOTE: A number of variables including the length of the adapter or extension, length of the
torque wrench, and variations in hand position on the torque wrench, will affect the
accuracy of the above calculation.

attempt to lubricate the wrench’s internal mechanism.
2. Clean wrench by wiping with clean cloth. Do not immerse wrench in liquids when
cleaning.
3. Store torque wrench in protective case at its lowest torque setting. Do not force
handle below its lowest setting.
4. Periodic re-calibration is necessary to maintain accuracy, once a year or after 5,000
times usage. An out-of-calibration torque wrench can cause damage to the tool.
MAJOR MAINTENANCE, SERVICE AND PART REPLACEMENT
1. Disassembly the torque wrench is not suggested. Please contact your local service
center if you have any question.
