What must be done to chains before use in towing?

Before using chains for towing, it is essential to inspect them for damages and replace them as needed. Inspecting chains ensures that they are structurally sound and free from any wear or deformation that could compromise safety during towing. This includes checking for links that may be bent, broken, or excessively worn. Identifying such issues beforehand helps prevent accidents that could result from chain failure while towing heavy loads.

Furthermore, if any damage is found, replacing the chains promptly is critical to maintaining the integrity of the towing setup. Using damaged chains could lead to severe risks during towing operations, potentially causing loss of control or accidents.

While lubrication can be useful for other hardware in some contexts, it is not a standard practice specifically required for chains used in towing, as it does not directly enhance their safety or performance during the task. Hence, the correct steps involve thorough inspection and replacement if necessary to ensure safety and reliability in towing operations.
