This is the factory Bomag Service Manual (document 008 911 53) for the BC 672 RB-2, BC 772 RB-2, BC 772 RS-2, BC 672 EB-2 and BC 772 EB-2 landfill compactors, matched to the serial ranges listed on its cover (S/N 101 570 57, 101 570 58, 101 570 59, 101 570 92 and 101 570 93). It is the English-language workshop book, 1022 pages, delivered as an instant PDF download.
This is the book for repair work, not the operator card in the cab. When a machine quits in the cell and the trucks keep tipping, it gives an independent mechanic the factory procedures to test, adjust and repair the machine instead of guessing.
With 15,181 bookmarks in the PDF, you can jump straight to the system you are working on. Bought once, downloaded, and yours to keep for as long as you run these compactors.
