NOTICE
If load chain needs replaced, then inspect chain guide and chain (load) wheel on hoist and idler
sprocket in 2-fall load block for excessive wear. A chain sprocket showing evidence of scored
pockets or sharp edges generated from wear SHALL be replaced. A worn chain sprocket or idler
sprocket can greatly reduce the life of load chain.
