Before using all models of dial torque wrenches, it is strongly
suggested to cycle/operate them 3 times at full scale in the torque
direction in which they will be used.
Dial torque wrenches must always be zeroed before use.
To set orange pusher and blue follower needle for right-hand (CW)
torquing:
1. Turn bezel in left-hand (CCW) direction until blue memory
follower needle contacts orange pusher needle.
2. Continue to turn bezel in left hand (CCW) direction until
blue memory follower needle is lined up up with zero (0)
of outer graduation on portion of dial for IN.LB., FT.LB.,
METRIC readings.
3. Apply force on the wrench handle until blue follower needle
reaches desired torque.
When force is released orange pusher needle will return to zero
and blue memory follower needle will remain at torque applied.
4. For repetitive torque operations (once the zero has been set
as instructed above), the blue memory follower needle can be
returned to zero by use of the follower needle knob. It is ready
for the next operation.
5. IMPORTANT – When using the memory feature always make
sure that the blue follower memory needle is on zero before
torquing.
