Manual Structural Overview

The documentation is partitioned into five primary technical segments. The general section introduces machine assembly drawings, comprehensive mass tables for every sub-assembly, and specific fluid-level requirements including oil and coolant capacities for diverse operating temperatures. Following the general introduction, the structure and function segment examines the mechanical architecture of the power train, hydraulic pumps, swing machinery, and track components. The testing and adjusting section focuses on diagnostic checks and calibration requirements, while the disassembly and assembly chapter details component removal sequences. The final segment, maintenance standards, provides tolerance charts and wear limits to assist in assessing components.

Technical Preview and Specifications

The manual details the hydraulic system, providing pressure specifications for components like the main pump, LS valve, and TVC valve. The S4D95L-1 engine performance data, including horsepower and torque, is documented for reference alongside electric wire coding tables. Reference-only technical values include the 10,700 kg operating weight of the PC100-6 model. The hydraulic tank capacity for both models is documented at 120 liters. Swing circle grease amounts are listed at 10 liters for early series and 6.5 liters for later variants. What an OEM service publication covers includes detailed diagrams of push-pull couplers and hoisting instructions to prevent handling damage. All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work.
