bolt rotation and/or that the outer disc is loose.

36.4 Cleaning
If a chain is very dirty it is recommended that it is replaced.
Dirty chains should be cleaned before they are lubricated, e.g. by
washing with solvent such as diesel or petrol.
The chain should be blown dry using compressed air and lubricated
directly after cleaning
NOTE!
Exercise care with degreasing agent as these can contain abrasives.
36.5 Lubrication
Mineral and synthetic oils can be used to relubricate Rexnord chains.
NOTE!
Lubricant must not contain substances such as molybdenum disul-
phide, PTFE or the like.
A lift chain should be offloaded from the weight of the fork carriage
(hanging free) when lubricated.
• Lubrication intervals:
- 500 hours with normal operations
- 100 hours when driving in rugged environments such as cold
stores and corrosive environments.
The chains are sprayed with lubricant. Note the entire chain must be
lubricated, even the fastening bolts. It is especially important that the
part of the chain which runs over the chain sprocket is well lubricated.
