A tandem roller you can't operate is a paving train standing still, and this Bomag BW 174 APO-4i operator manual PDF puts all 292 pages of the factory's answer between you and the next mat. It is Bomag document 008 202 87 EN, the official operating and maintenance instructions for this tandem vibratory roller. The LC display unit, operating console and travel lever console each get their own walkthrough, so every switch on the driver's stand has a function you can look up. Maintenance runs on hour marks from 50 through 3000, and troubleshooting pairs engine fault tables with the full fuse assignment for the central electrics. Offset the crabwalk to its full 1130 mm; torque the precision spreader's fastening screws to 10 Nm. When it's just you, the roller and a cooling mat, nobody is answering the phone. This bookmarked, text-searchable PDF gets the machine back in the pass.
