GM-2-5AX - Installation Guide
Remove Rust Inhibitor
For ease of removal, first use a plastic scraper to remove most of the rust inhibitor and then use WD-40 or another
PH neutral degreaser to spray all the way covers and other non-painted surfaces that have been coated with rust
inhibitor. Let it soak for a few minutes before removing it. Then use shop towels to remove it. For thick applications of
rust inhibitor use a plastic scraper to remove it.
Important: Do not use scotch-brite or metal scrapers, these will scratch the way covers. Furthermore, to avoid any
contamination of the way cover seals with the sticky residue. Do not move any of the axes until all the rust inhibitor
has been removed.
