When replacing load chain, check for wear on mating parts, i.e. Load Sheave,
Chain Guides and Idler Wheels, and replace parts if necessary. Remove old chain. Remove hook
set assemblies, limit locks, stoppers and end connections from the chain for reuse on new chain. If
the load chain is being replaced due to damage or wear out, prevent its reuse by destroying the old
chain.
