My 1013 Manual reads "Clean X & Z screw rods and rails with thinner/lighter lubricant that is equivalent to ISO-32 or lighter than SAE-20. Grease Y axis gear and rack with thicker/heavy lubricants. Clean up excessive oil from gear and rack with clean cloth. DO NOT APPLY DRY CLEAN LUBRICAN."
Is there additional information or specifications on what "thicker/heavy lubricants" mean?
