23. Ensure the pin attaching the fly section to the boom base
section stowage bracket (Figure 4-12), (Detail D) is in
place.
24. Remove the retainer clips and attachment pins from the
anchor and attach fittings on the right side of the boom
nose and stow them in the base of the swingaway.
25. Remove the clip pin and pin securing the boom
extension alignment device. Place the boom extension
push bar assembly in the stowed position and secure it
in place with the pin and clip pin.
26. Extend the boom enough to engage the boom stop
block.
27. Rig the boom nose and hoist cable as desired and
operate the crane using normal operating procedures.
Setting the Folding Swingaway Offset
1. Extend and set the outriggers and swing the boom to
over the front. Position the boom to above horizontal.
2. Block under the tip of the extension assembly section.
3. To set the offset from a lesser degree to higher degree
perform the following procedures:
a. Slowly lower the boom until the pressure is relieved
on the offset link pins.
NOTE: Make sure the mast is in the raised position.
b. Remove the offset link clip pins and attach pins
securing the offset links in the lesser degree offset
position. If going to maximum offset stow them in
the stowage lugs. If going to the intermediate (25
degree) offset install them in the offset links for that
degree of offset.
c. Slowly elevate and telescope the boom at the same
time so that the extension does not move off of the
blocking until the offset links take the full weight of
the extension.
d. Reeve the hoist cable as described under normal
erecting procedures.
4. To set the offset from higher degree to lesser degree,
perform the following procedures:
a. Slowly lower the boom until the pressure is relieved
from the offset links.
b. Remove the offset link clip pins and attachment pins
and lower the boom until the holes for the lesser
degree offset position align in the offset links. Install
the offset pins and clip pins.
c. Slowly elevate and telescope the boom at the same
time so that the extension does not move off of the
blocking until the offset links take the full weight of
the extension.
d. Reeve the hoist cable as described under normal
erecting procedures.

base extension anchor fittings and the boom nose attach
fittings could cause these fittings to contact each other
during operation of the boom.
DANGER
Crushing Hazard!
Ensure any blocking material used is adequate to support
the weight of the extension assembly without tipping or
falling.
CAUTION
Possible Equipment Damage!
Do not overload the extension anchor fittings or the
extension base section when lowering the boom.
CAUTION
