*a	Fulcrum length

HINT:

Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (See page ).
Make sure SST and the wrench are connected in a straight line.
