25. Remove the outer mid retract cables from the attach-
ment fixtures at the front of the boom base section.
26. Attach an auxiliary hydraulic power source to the
telescope cylinder and extend the cylinder rod
enough to turn the trunnion in a vertical position.
27. Pull the inner mid, outer mid, and fly boom sections
out of the base boom section. Use additional lifting
devices and reposition any lifting straps as neces-
sary as the sections are withdrawn. It will be helpful
during this step to pull the outer mid retract cable
out from the front of the base section as the other
sections are being pulled out. This will prevent the
cables from tangling as the sections are withdrawn.
