the fly section to the front. Insert the threaded ends
through the holes on the front of the fly section and
install a washer and nuts on each cable end.
WARNING
Ensure the telescope cylinders are securely blocked and
some means used to hold them together to prevent any
accidental movement. Severe injury can occur if the
cylinders drop.
13. Using an adequate lifting device, position the upper
telescope cylinder onto the lower telescope cylinder.
