Kobelco
Kobelco excavator manuals in PDF, and only excavators: the company that built Japan’s first hydraulic excavator, the 1963 TY45, is represented here by its SR short-radius minis such as the SK17SR-5 and SK25SR-6, by the micro SK08, and at the large end by the SK350-9.
Kobelco shop manuals carry a book code that starts with S5, such as S5PU0023E01 on the 396-page SK17SR-5 manual, and that code is the quickest way to confirm you have the right book. The SK350-9 manual covers Tier 4 machines from serial YC12U2400 up, from the Hino engine to the track links, across 1,387 pages.

Choosing the Right Kobelco Manual
Repair Manuals hold the single-machine shop manuals, with hydraulic circuits for boom, arm, and travel, wiring, and service standards. The older SR minis sit in Parts Manuals mostly as combined sets, a shop manual with its parts books, which suits an owner rebuilding an older SK30SR on a tight budget. Between 2002 and 2012 Kobelco machines were also sold as Fiat-Kobelco and New Holland Kobelco, and the Fiat-Kobelco books, such as the E30SR and E35SR, are filed under Fiat.
Are these Kobelco factory shop manuals?
The single-machine shop books carry an S5 code. The SK08 manual, S5PT0009E01, runs 344 pages from engine disassembly to hydraulic pressure adjustment, with symptom-based troubleshooting. The SK50SR-3 manual is S5PJ0009E-01. Compare the code with the one your dealer quotes and you know it is the same document.
My Kobelco serial starts with letters like PV08. Does that matter?
Yes. Kobelco splits documentation at serial breaks, and the letter prefix is part of the break. The SK25SR-2 set carries one parts manual for PV08-20001 and up and another for PV09-22001 and up, and its shop manual covers every engine fitted, from the 2TNE68 to the 4TNE88. On the large machines the break is in the title: the SK350-9 book starts at YC12U2400.
