It is very important the blades are installed properly and
not backwards. When looking at the front of the tur-
bine from an
upwind
position, the leading edge tape
should be as shown in the picture to the right. When
looking at the blades from an
upwind
position, they will
rotate in a clockwise direction.
Install the blade bolts with the head of the bolt against
the hub plate as shown in the figure to the right. It is
important that the threads of the bolts are pointing into
the wind.
Place the blade straps across the front of the blades, and
tighten the nuts to 18 foot-lbs of torque.
