Don't you have an Operation & Maintenance Manual..? A good investment - ask your Cat dealer for the correct O&MM for your Serial Number of machine. Not sure what they cost these days but it's not expensive (less than $100 I would guess). There are 8 different ranges of 308 and possibly there is more than one O&MM.
