General Safety Information
Your torque wrench was calibrated and tested before leaving the factory and is guaranteed to meet or exceed
$60(%VWDQGDUG
Because your torque wrench is a precision measuring instrument, it should be serviced only by authorized service centers.
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.

To calculate the new torque output of the torque wrench, use the following:
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.
TW = Torque wrench scale reading
TA = Torque exerted at end of adapter
L = Distance betweeen square drive and hand position
A = Length of adapter or extension
TW = TA x L
L=A
