Drive controls, service intervals, and daily checks for the BW177 roller family are settled in one document: the 114-page Bomag BW177D-50, BW177DH-50, BW177PDH-50 operator manual PDF, printed by the factory as document 0852820 for these three single drum vibratory roller variants. Maintenance takes up close to half of the book, walking you from the running-in schedule through engine oil changes, drive axle and vibration bearing oil, hydraulic filters, and parking brake adjustment. Before any of that, the indicator descriptions and pre-start tests tell your operators what every light and lever means, and the safety chapter covers loading, towing, and jump-lead starts. Set intake valves to 0.35 mm, exhaust to 0.50 mm, and torque wheel nuts to 550 Nm when they come off. A roller sitting idle while somebody hunts one interval stalls the whole lift. Bookmarked and text-layered, this PDF is wherever the machine is.
