There are several places that sell english repair manuals. Some of the advertisers on this websit for instance. However, please call anyone you order from to confirm exactly what you are getting. I ordered a service manual for a 2610D and got one for a 336D. Its ok for the proceedures to repair but lacks greatly in many areas. For instance the 336 has a different engine, it has a hydraulic system that INCLUDES power steering and other opitions ETC. 2610 has no power steering. Diagnosing a hydro failure will be impossible because of the 2 different systems. The list goes on but I think you get the picture.
Also, my manual has alot of photos, 90% of them are worthless. The black and white photocopy of these color photos turns out BLACK and you can see nothing. Its very irritating when the you are directed to look at photo and cannot see anything.
