An hour from now you could be at the pressure test bar with this Bomag MPH 122-2 service manual PDF open on the screen: 658 factory pages for the soil stabilizer and asphalt recycler, OEM 008 917 87. Circuit diagrams close the book, from hydraulic diagram 593 301 24 through the machine wiring to separate electric, hydraulic, pneumatic and heating schematics for the bitumen metering system. Fault tracing on the Deutz TCD 2015 V6 runs from flashing codes through SERDIA and CAN-bus diagnostics to the full EMR3 fault code list, and the A4VG56 travel pump and A4VG180 rotor pump each get their own troubleshooting sections. Crank the starter one minute at most, then let it cool 30 minutes; never heat oils past 160 degrees C. Misdiagnose a rotor pump and you pay for the rebuild twice. Pay once here, and a bookmarked, text-searchable copy stays with your machine for good.
