Hitachi Sumitomo ZAXIS70, ZAXIS70LC, ZAXIS80SB, ZAXIS80SBLC, ZAXIS85US 2006 Operators Manual

I’ve torqued enough head bolts to know that aftermarket manuals are a gamble you don’t want to take on a $150,000 excavator. This 2006 Hitachi Sumitomo ZAXIS70, ZAXIS70LC, ZAXIS80SB, ZAXIS80SBLC, ZAXIS85US Operators Manual is the factory binder – 313 pages, OEM part number EM1CD–EN4–2. If you’re running a ZAXIS70 on a job site in San Antonio or anywhere else in North America, you need the real spec sheet, not some third-party reprint that guesses at fuel viscosity or hydraulic pressures. This manual covers five model variants: ZAXIS70, ZAXIS70LC, ZAXIS80SB, ZAXIS80SBLC, and ZAXIS85US. Serial numbers are listed inside – ZAXIS70 and 70LC from 060001 up, 80SB and 80SBLC from 060001 up, 85US from 040001 up. Keep this book with the machine, not buried in a toolbox.

SAFETY Signs and Pre-Start Checks

First thing I look at in any manual is the safety section. Hitachi doesn’t waste words. Pages 3 through 20 cover safety signs, hazard labels, and daily inspection procedures. The manual specifies atmospheric operating limits: –4°F to 104°F (–20°C to 40°C), altitude up to 6600 ft. If you’re running outside those ranges, Hitachi says call your dealer before you cook the engine. The engine oil pressure indicator, coolant temperature gauge, and fuel level indicator are all explained in the monitor panel section. There’s a specific cold-weather start procedure on page 45 – don’t skip it if you’re working north of the Rio Grande in January.

Operator’s Station: Monitor Panel and Controls

Your operator spends 10 hours a day in that cab. The manual dedicates 30 pages to the operator’s station – cab features, monitor panel layout, the LCD display, trip meters, and every switch on the panel. The fuel gauge, auto-idle indicator, air filter restriction indicator, and overheat indicator are all drawn with their locations. If a warning light comes on and your guy doesn’t know what it means, he’s going to ignore it until something grenades. The manual also covers optional items like the auto air conditioner, 12-V power source, and fire extinguisher installation. There’s a procedure for adjusting the seat and the air-suspension seat – your guys’ backs will thank you.

Break-In and Engine Operation Procedures

New machine or after a major rebuild? The break-in section starts on page 56. It tells you to monitor engine operation closely for the first 50 hours, check everything every 8 hours or daily, then change fluids at 50 and 100 hours. The engine operation chapter covers starting in ordinary and cold weather, using booster batteries, and stopping. It includes the exact sequence for the preheat indicator and engine control dial. The manual uses metric hardware – that’s stated up front. You’ll need metric tools, so don’t show up with a 9/16″ wrench expecting it to fit the hydraulic fittings.

Maintenance Guide: Fuel, Engine, and Hydraulic Systems

The maintenance section runs over 80 pages. It opens with a guide table that lists intervals for greasing, engine oil changes, fuel filter replacement, hydraulic oil filter restriction checks, and transmission inspection. The manual tells you to use correct fuels and lubricants – it specifies fuel types and viscosity grades for your region. Pay attention to the secondary relief pressure adjustment when running a hydraulic breaker or crusher. The attachment section covers piping for breakers and crushers, plus object handling. There’s also an emergency boom lowering procedure for machines with and without a hose-rupture safety valve. That alone is worth the price if you ever have a line blow.

Transporting and Lifting the Machine

Loading a ZAXIS80SB onto a trailer? The transporting chapter covers road transport, loading/unloading on a trailer, and the machine lifting procedure. It gives the shackle hole usage diagram – don’t lift from some random tie-down point. The manual also details towing a short distance and operating on slopes. Parking on slopes gets a dedicated subsection with step-by-step instructions. If you’ve ever seen a excavator roll because someone didn’t chock the tracks, you’ll read that section twice.

Does this manual cover the ZAXIS85US model?

Yes. The manual covers ZAXIS70, ZAXIS70LC, ZAXIS80SB, ZAXIS80SBLC, and ZAXIS85US. Each model’s serial number range is printed inside the manual.

What is the page count?

313 pages.

Is this a service manual or an operator manual?

This is the 2006 Operators Manual. It includes daily operation, pre-start checks, break-in, driving, basic maintenance, and transport procedures. It does not contain full engine or hydraulic rebuild specs – that is in the Factory Service Manual (sold separately).

What fuel specifications are listed?

Hitachi specifies using correct fuels and lubricants with recommended grades for the engine. The Maintenance Guide Table includes fuel filter change intervals. Exact fuel grade recommendations are given in the “Use Correct Fuels and Lubricants” subsection. You’ll need to check the manual for the specific viscosity and cetane rating – it varies by operating temperature.

Every job I’ve seen go wrong on these ZAXIS machines came down to someone using a generic online PDF that skipped steps or had a torque value one decimal off. This 2006 factory Operators Manual gives you the OEM procedure for starting the engine in cold weather, safe operation of the backhoe and face shovel, and the correct maintenance intervals for the fuel system, engine oil, and hydraulic filters. Don’t send a green operator into a ZAXIS70 cab without this book. Access the Factory Manual from AutoRepairManuals, print it, and keep it in the machine’s document compartment. Your wallet – and your insurance agent – will thank you.
