Part of the Yanmar Operator Manuals.
All 160 pages of this Yanmar ViO17–ViO57 Series Operation Manual (OEM #LGBBF0-00017) cover one family of mini excavators: the ViO17 (EP), ViO20-3, ViO25-3, ViO30/35-3, ViO50U, and ViO57U. Inside, hydraulic schematics trace full circuit routing while wiring diagrams cover every electrical path; a detailed controls section breaks down monitor displays, switches, and lever-pedal functions variant by variant. You also get structured troubleshooting separating actual faults from normal operating phenomena, maintenance interval tables, fluid and oil temperature guides, and a standard torque table for bolts and nuts. Replace the main pump outlet hoses (P1, P2, P3) at 4,000 hours or 2 years, and confirm crawler tension at 8–13 mm before you roll. Your machine is down. One click downloads this bookmarked PDF; search any spec, jump any section, and get back to work.
