Technical Specification Previews

Beyond just part numbers, this manual provides critical factory data for unit maintenance. The fluid capacity for the hydraulic reservoir is documented at 17 liters. Because heavy equipment maintenance carries inherent physical risks, always verify system relief valve settings—specified here at 1750 P.S.I. (12,068 kPa)—before testing or adjusting high-pressure circuits to prevent equipment damage and ensure safe operation.

Mechanical assembly data includes a required torque value of 83 lb-ft (113 Nm) for the transmission shaft. For the electrical system, it lists a 51 Amp alternator output alongside an established 138 Amp-hour battery capacity. This instant download delivers immediate access to these essential specs directly to your tablet or laptop while you are standing at the workbench. If you want to dive deeper into how factory workshop documentation is structured, reviewing typical service layouts can significantly streamline your diagnostic process.
