valve (2) with your hand.
4) Refer to the formulas shown where:
D TS = the applicable torque setting
for the torque spanner.
D TT = the specified torque setting for
the coupling nut.
D D1 = the distance from the center of
the square drive to the center of the
hand grip.
D D2 = the distance from the center of
the square drive to the center of the
adapter.
