Hitachi ZX350LC-6 & ZX350LCN-6 Excavator Repair Manuals PDF

This Hitachi DDQ50 manual set supports service work on ZX350LC-6 and ZX350LCN-6 hydraulic excavators. The workshop reference is paired with two technical books: one explains operation, while the other addresses performance tests and troubleshooting.

Included documents and coverage

• WDDQ50-EN workshop manual: 689 pages covering general preparation, maintenance standards, upperstructure, undercarriage and front attachment.
• TODDQ50-EN operational-principle manual: 478 pages of general, system and component-operation information.
• TTDDQ50-EN troubleshooting manual for diagnostic procedures, tests and adjustments.
• Electrical and hydraulic circuit diagrams accompany the manual set.

Choosing the correct reference

The troubleshooting index addresses monitor information, component layout and air conditioning, with aftertreatment and diesel-exhaust-fluid topics relevant to this -6 documentation. Match the exact LC or LCN designation and installed equipment to the applicable section. Production changes and optional systems can affect which circuit or procedure is suitable. Use the operational-principle book for the system explanation, then the diagnostic and workshop references for the task being investigated. The DDQ50 code helps distinguish this set from the DDD books for similarly named -5B machines.
