Sign off on the lubrication process

WARNING! Failure to maintain clean and well lubricated load chain will result in rapid load chain wear that can lead to chain failure which can cause severe injury, death or substantial property damage.

1. Lubricate load chain weekly, or more frequently, depending on severity of service.

2. In a corrosive environment, lubricate more frequently than normal.

3. Lubricate each link of the load chain and apply new lubricant over existing layer.

4. If required, clean chain with acid free solvent to remove rust or abrasive dust buildup and lubricate the chain.

5. Use Ingersoll Rand LUBRI-LINK ® or a SAE 50 to 90 EP oil.

1. Lubricate the hook and hook latch pivot points. Hook and latch should swivel / pivot freely.
