IMPORTANT WARNINGS
Failure to follow warnings and instructions can result in serious injury or death.
 

Also, read the important warning pages, "General Safety Information" 
These warnings also apply to chain and chain assemblies. Only additional warnings and information are listed below.
Never exceed the Working Load Limit of the chain.

The Working Load Limit is the maximum load that should ever be applied to the chain, even when new and when the load is uniformly applied. Working Load Limit applies only to straight line pulls. When using multiple leg chain slings, the Working Load Limit of each leg will have to be reduced considerably depending on the angle of the sling legs. Consult industry recommendations for information, such as ASME B 30.9.

When in doubt as to the Working Load Limit of the chain, refer to the periodic, permanently embossed grade marking on chain links. Proof Coil Chain is identified by P.C. or 30 or 3 or 28; HighTest Chain by H.T. or 43 or 40 or 4; Transportation Chain by 70 or 7; Alloy Chain by 80 or 8 or 800.
Use only alloy chain for overhead lifting.
Grade 80 alloy chain is the only type of chain which can be used for overhead lifting. Use only grade 80 alloy fittings for overhead lifting.
Attachments must have at least the same Working Load Limit as the chain used.

Hooks, links, shackles, etc. must be of suitable material and strength to provide adequate safety protection.
Keep out from under a raised load.
Do not move load over people. Do not ride on load. Conduct all lifting operations in such a manner that if equipment were to fail or break, no personnel would be injured. This means KEEP OUT FROM UNDER A RAISED LOAD, DO NOT OPERATE LOADS OVER PEOPLE AND KEEP OUT OF THE LINE OF FORCE.
Avoid shock loads.
Avoid impacting, jerking or swinging of load. Working Load Limit will not apply in these circumstances because a shock load is generally significantly greater than the static load.
Inspect chain frequently.
No product can keep operating at its rated capacity indefinitely. Closely examine each link for deformation, cracks, elongation, corrosion,rust, etc. Take chain out of service even if only one bad link is found. Eliminate twists and kinks in chain before using. Do not attempt to repair damaged or worn links in a chain. Do not attempt to weld, anneal, heat treat or hot galvanize alloy chain - its capacity will be completely destroyed. Protect chain from corrosion.
Destroy, rather than discard, chain that is judged to be defective.
Chain that is not destroyed might be used again by someone not aware of the hazard associated with that use. Destroying chain is best done by cutting it up into short pieces.
Chain Slings.

Only grade 80 alloy chain can be used for overhead lifting.
Refer to OSHA standard 1910.184 and ASME standard B30.9 for design factors and other important information. Other standards and information may apply depending on specific use.
