Engine, electrical, hydraulics, drum drive, parking brake, vibration, steering and chassis all run start to finish through this Vibromax 752 service manual PDF, publication SM70501, a 190-page shop book for the 752 tandem drum roller. Electrical work fills a big share of the book, with schematics for the starter, charging, lighting, water sprinkler and vibration control circuits plus wire charts for the right panel, left panel, front and rear harnesses, so you can trace a dead lamp back to its connector. Hydraulic schematics trace the propulsion, vibration, steering and brake circuits, and the pressure test points are laid out so you know where to tee in a gauge. Look for 18 to 30 bar of charge pressure at test point MP5, and torque a 20 mm x 1.45 tube nut to 45 Nm (33.2 ft-lbs). A roller with no vibration idles the whole paving crew. The bookmarked, text-searchable PDF travels on your laptop to wherever the 752 is parked.
