the boom to minimum elevation to permit ease of

cable must be removed from the sheave.
4. Attach the swingaway to the boom nose using steps 5
thru 21 of Erecting The Bi-Fold Boom Extension
Assembly.
5. Extend the boom as necessary to permit sufficient
clearance for installation of the 20 ft (6.1 m) Extension
Insert; then lower it until the tip of the bi-fold extension
assembly is laying on the ground. Block up under the bi-
fold extension, approximately 8 to 10 ft (2.4 to 3.0 m)
ahead of the boom nose.
6. Remove the four retainer clips and attachment pins that
secure the bi-fold extension to the boom nose.
7. Retract the boom leaving the bi-fold extension on the
blocking.

the lifting lugs and position it at the base end of the bi-
fold extension.
9. Mate the Insert to the bi-fold extension and install the
four attaching pins and retainer clips removed in step 6.
10. With the hoist cable still attached to the Insert, lift the
assembled unit and move the blocking, erected in step
5, to approximately 8 to 10 ft (2.4 to 3.0 m) ahead of the

be necessary to raise or lower the boom slightly to mate
the attach lugs.
NOTE: If the Insert attach lug holes are not in lateral
alignment with the holes in the boom nose anchor
fittings to install the pins, adjust the upper and
lower cross strut adjustment screws on the Insert to
align the holes.
15. Remove the retainer clips from the four attachment pins
stowed on the Insert and install them in the attachment
Grove
and anchor fittings on both sides of the boom nose.

insert.
