TIMING, ALIGNMENT, AND FINAL PRESERVATION OF METALWORKNG MACHINERY

a. Metalworking machinery that has been disassembled and reassembled while being processed for storage

should be operated at all speeds and feeds to ensure that tinting is correct and that all parts are in alignment and function

properly.

b. Metalworking machinery will be preserved in such a manner that the preservative will afford the best

possible protection while the equipment is in storage. The type of preservatives used may vary according to the storage

category in which the equipment will be maintained.
