The hydraulic repair sections provide detailed procedures for servicing the main pumps, control valve, pilot controls, centre joint, swing motor, travel motors and hydraulic cylinders. This information is valuable when repairing machines affected by weak hydraulic performance, slow attachment movement, poor travel response, abnormal noise or hydraulic oil leakage.

Detailed dismantling and assembly procedures show the correct sequence for working on major components. Inspection measurements, clearances and service limits may be included to help identify worn, damaged or incorrectly adjusted parts before reassembly.

The Hitachi ZX350LC-6 Workshop Manual also contains important upperstructure repair information. These sections may cover the cab, counterweight, engine-related equipment, hydraulic components and assemblies mounted on the revolving frame.

Undercarriage information provides workshop procedures for inspecting and repairing tracks, rollers, idlers, sprockets and associated components. Correct track adjustment and regular inspection can help reduce premature wear and maintain dependable travel performance.

The boom, arm and bucket sections explain the correct methods for removing, installing and repairing the excavator’s front equipment. This includes hydraulic cylinders, pins, bushes, linkages and attachment components.

Electrical workshop information assists with identifying and servicing wiring, sensors, switches, connectors, solenoids and other electrical equipment. Technical diagrams help technicians understand component positions and system connections during repair work.

Following the procedures in this manual can help prevent incorrect dismantling, assembly mistakes and damage to expensive components. Correct torque settings, inspection standards and installation procedures are especially important when completing major hydraulic, mechanical or undercarriage repairs.

The manual is also useful when planning repairs before dismantling begins. Technicians can review the required tools, component sequence, inspection points and specifications in advance, helping reduce downtime and improve workshop efficiency.

Using the Hitachi ZX350LC-6 Workshop Manual can help ensure that repair work is completed using the manufacturer’s recommended methods. It provides a valuable reference for routine servicing, component replacement, major overhauls and complete machine restoration.
