Hitachi Sumitomo ZAXIS650LC-3, ZAXIS670LCH-3 2006 Operators Manual

Running a Hitachi Sumitomo ZAXIS650LC-3, ZAXIS670LCH-3 2006 Operators Manual in the cab means you’ve got the exact document Hitachi wanted with that machine. I’ve seen too many guys trust a third-party PDF that misses the machine numbers page or prints torque values in wrong units. This 365-page factory manual won’t do that. It’s the real deal – printed on recycled paper in Japan, part number EM1J7-1-1. If you’re a mechanic, operator, or owner who wants to keep that excavator running without burning up a pump, read on.

What the 365 Pages Cover

Page 1 states the manual uses SI units with MKS and English equivalents in parentheses. Example given: 24.5 MPa (250 kgf/cm², 3560 psi). That’s the kind of precision that stops you from guessing whether a fitting needs 3500 or 3600 psi. Page 3 holds the Machine Numbers section – you fill in the serial number for the machine and hydraulic components. Your dealer needs those numbers to order parts. Lose that page and you’re calling around guessing serial numbers. The manual also covers warranty terms, safety rules, and the machine’s metric design requirement. This isn’t a repair manual; it’s the operator’s bible for daily checks, travel, and basic maintenance.

Machine Numbers: Don’t Skip Page 3

Fill in the manufacturing numbers for the machine and each hydraulic component. Right there on page 3. If you ever need to order a swing motor seal or a main control valve, you’ll be glad you wrote it down. I keep a copy of those numbers in my toolbox and a second copy in the cab. The manual tells you to file them off the machine too – smart move in case the manual gets lost. That section is sixty seconds of work that saves hours of downtime later.

Operator Safety – The Manual Doesn’t Mess Around

Hitachi prints it black and white: only qualified, licensed operators should run this machine. Personal injury or machine damage happens when you skip the safety section. The warranty becomes void if you abuse the equipment – say, cranking up fuel delivery beyond spec. This manual includes that warning on page 2. I’ve had to explain to a shop owner why his machine wasn’t covered after he turned up the pump pressure. Factory document covers your back. Read it.

Who Needs This Manual on the Workbench or in the Cab

Operators who want to avoid costly mistakes. Mechanics who need factory-recommended daily inspection steps. Owners who want to maintain warranty coverage. Even DIYers with a heavy-equipment habit – this manual walks you through starting precautions, travel controls, and hydraulic circuit operation without assuming you’ve run a dozen excavators. The language is direct. Illustrations are from the actual Hitachi engineering drawings, not aftermarket redraws. For a deeper dive into mechanical transmission fundamentals, see Manual Transmission. And for the clutch and gear train basics, check Manual Transmission.

Factory OEM vs. Aftermarket – No Contest

I’ve handled aftermarket operator’s manuals that swap metric and imperial threads – that’ll strip a fitting fast. This OEM manual is explicit: machine is metric design, use only metric hardware. The introduction says measurements are metric with English in parentheses. No conversion errors. No “close enough” torque values. If you want the real Hitachi Sumitomo documentation that came with the machine, get this. Aftermarket copies often reprint the intro but skip the machine numbers page or safety decal locations. Here you get all 365 pages, original print from 2006.

FAQ

Does this manual include full service and repair procedures?

No. It covers operation, daily checks, and basic maintenance – not engine or hydraulic overhauls.

How do I confirm my serial number matches the coverage in this manual?

This manual covers serial number 20001 and up for both ZAXIS650LC-3 and ZAXIS670LCH-3 models. Locate the machine identification plate on the right-hand side of the main frame near the cab – it’s stamped into steel. Write that number in the Machine Numbers section on page 3. Your dealer will verify compatibility from that number. If your serial falls outside 20001 and up, you may need a different edition. The manual’s part number EM1J7-1-1 is printed on every page footer – confirm that matches your machine’s original manual if you have one.
