LUBRICATION

General

Thread lubricant or an anti-seize compound use is recommended for threaded shafts, capscrews and nuts. Unless otherwise stated, remove old lubricant, clean part with an acid free solvent and apply a new coating of lubricant to part before assembly.

Gear

Remove prevailing torque type nut (60) on side of hoist opposite hand lever and remove gear case assembly (1). Remove old grease and replace with new. For temperatures -29° to 10° C use EP 1 grease or equivalent. For temperatures -1° to 49° C use EP 2 grease or equivalent.

Load Chain

WARNING

•Failure to maintain clean and well lubricated load chain may result in chain failure causing injury, death or substantial property damage.

1.Lubricate each link of chain weekly. Apply new lubricant over existing layer.

2.In severe applications or corrosive environments, lubricate more frequently than normal.

3.Lubricate hook and hook latch pivot points with same lubricant used on load chain.

4.To remove rust or abrasive dust buildup, clean chain with an acid free solvent. After cleaning, lubricate chain.

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