Extension Cylinder and Cable Assembly
Installation
Procedure:
1. Attach two lifting slings to the extension cylinder.
Using suitable lifting equipment, raise and slide
the end slowly into the counterweight end of the
boom assembly. The upper cables can be tie-
wrapped to the cylinder to keep them from getting
tangled. Be sure to remove the tie wraps as the
cylinder is being installed.
NOTE
Make sure the cables do not get tangled or caught
on other components.
2. Orient the cables correctly. Identify which cable
ends go to the platform end, and which go to the
counterweight end of the machine. The narrow
end of the cable support is towards the platform
end of the machine when installed.

link on the end of the cylinder support.

pushed in.
