4. Insert the last link into the pulley of the upper
hook (D), moving the chain up, around, and

twisted and welds face away from the pulley.
5. To prevent the chain from free-wheeling, insert
a screwdriver securely into a link at the base of
the upper pulley (left side).
6. Insert the last link into the right pulley of the
lower hook (E).
7. Pull the load chain through and up from the
underside of the pulley (E, F).
