For longer life, lightly coat the load chain with machine or gear oil. Ensure that the oil is applied to the
bearing surfaces of the load chain links.

The load chain lubrication should be accomplished after cleaning the load chain with acid free cleaning
solution. Use approved lubricant in
Table 6-1

For dusty environments, it is acceptable to substitute a dry lubricant.
