Operation 25
Adjusting the Wrenches
1. Measure the tool joint with OD
calipers.
2. Use the 1 1/4" wrench to adjust the
Pointer (P) on the Pipe stop index
(PI) to the OD tool joint size. It’s
always better to adjust the pointer
1/4" larger than the measured
diameter of the tool joint.
3. For safety, adjust the Top wrench nut
(TN) 1" larger than the Middle
wrench nut (MN) and the Bottom
wrench nut (BN).
4. Rotate the Middle wrench nut (MN)
and the Bottom wrench nut (BN) to
the OD tool joint size. Visually align
the end face (F) of the wrench nut with
the scale (S) on the wrench.
