becomes misaligned while torque is applied, the bolt must be loosened and the washer realigned.

For the attachment of the second blade, the hub is rotated so that the blade can be mounted with

its tip supported, as was done for the first blade. The first blade will need to be supported

initially by slings attached to a boom truck or crane. Once the hub is in the correct position the

parking brake can be applied and the boom truck released. The procedure for mounting and

aligning the second blade is as for the first one. The procedure for attaching the third blade is

described in the Section 6.5.
