19. Pull the intermediate boom straight out of the outer
boom. Reposition the slings as needed so the
intermediate boom balances when removed from the
outer boom. Set the intermediate boom down on
blocks on a hard, level surface.
20. Inspect the boom and welds. Contact the local Sky
Trak distributor or the JLG Service Department at
1-877-554-5438 or 1-717-485-6657, if structural
damage is detected.
21. Inspect all wear pads for wear. (Refer to Section
3.9.1, “Wear Pad Inspection.”)
22. Inspect hoses, hardware, mounting points, chains
and other components visible with the intermediate
boom removed. Replace if damaged.
23. If you are replacing the intermediate boom with a
new boom section, the following items need to be
removed from the intermediate boom:
a. Remove the capscrews (1), lockwashers (2) and
flat washers (3) holding the bottom wear pad (4)
and spacer (5) to the intermediate boom. Label
the wear pad and spacer as “Bottom.” Save the
capscrews, lockwashers, flat washers, spacer
and wear pad inserts (6).
b. Remove the capscrews (7), lockwashers (8) and
flat washers (9) holding the upper wear pads (10)
and shims (11) to the intermediate boom. Label
the wear pads and shims as “Top Left,” “Top
Center” or “Top Right.” Save the capscrews,
lockwashers, flat washers, shims and wear pad
inserts (12).
c. Remove the capscrews (13), lockwashers (14) and
flat washers (15) holding the side wear pads (16)
and shims (17) to the intermediate boom. Label
the wear pads and shims as “Left Side Top” and
“Right Side Top/Bottom.” Save the capscrews,
lockwashers, flat washers, shims and wear pad
inserts (18).
WARNING:
NEVER weld or drill the
boom. The structural integrity of the boom will
be impaired if subjected to any repair involving
welding or drilling. Failure to comply can result
in death or serious personal injury.
