indicator receiver in the cab will not register the weight being
lifted by the single part line.
NOTE: Crane may have shipped from the factory with a
sleeve in the downhaul weight for use with 1/2 in
wire rope. If the crane is equipped with 5/8 in wire
rope, it may necessary to remove the sleeve from
the downhaul weight to allow for installation of the
becket pin for 5/8 in wire rope. The sleeve can be
removed by pressing it out.

rope is engaged in the sheave grooves in both the boom
head and hoist block and is wrapping on the hoist drum
properly.
