The Core Splitter is a very robust piece of equipment and only needs a full service every five years or so. The Core Splitter should only be dismantled under the direct supervision of the Lab Officer or their appointed designee. Have the ship's electricians isolate the power to the Core Splitter before beginning the work.
The following images document, in part, the full dismantling of the Core Splitter in 2015. Additional images are in the Uber Saw folder in IODP_Share.
