Part of the Yanmar Repair Manuals.
All 418 pages of this Yanmar ViO17 Service Manual zero in on one machine: your 2009–2012 mini excavator, from hydraulic pump to rubber crawler undercarriage. Inside you get the full hydraulic circuit schematic covering every actuator (boom, arm, bucket, swing, blade, travel, track gauge change), plus monitor and alarm wiring diagrams with complete circuit descriptions for engine start, stop, and battery charging. Open to the Service Standards chapter and you'll find a tightening torque list covering every critical fastener on the machine and engine, alongside exploded views and step-by-step teardown procedures for the hydraulic pump, control valve, pilot valve, swing motor, and travel motor. Torque your sprocket bolts to 44.1–58.8 N·m; set the track roller nut to 78.5–98.1 N·m. Your machine is down and the clock is running. Grab the PDF on any device, search by keyword, and get the factory answer without guessing.
