BLADE TORQUE

While lifting the turbine pay attention to the armored cable and ensure that it is
not crushed at any point in the process. The blades have a procedure for being
torqued. Start with 50 ft⋅lb. then back off a ¼ turn, 75 ft⋅lb. then back off a ¼ turn,
100 ft⋅lb. then back off a ¼ turn, 125 ft⋅lb. then back off a ¼ turn and final torque
at 150 ft⋅lb.
At this time the tag line should be installed to assist in raising the turbine.
