valve (2) with your hand.
4) Refer to the formulas shown where:
D
TS = the applicable torque setting

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.
5) Use the torque spanner (94012) and
