DO NOT SUBSTITUTE BOLTS. Only the AOC supplied Grade 8, fine thread bolts, 5/8" x
3", should be used to secure the blades to the hub. The tip brakes can be unlatched or
removed (if necessary) to prevent damage during the mounting process.
The four corner bolts on the blade should be installed, initially without the washers, to hold the
blade in place. The pitch tool should be inserted first, in slot #1 (see Figure 6.10), and secured
with a bolt inserted snug tight.
