Offers a complete guide to repair and maintenance of Hyundai R250LC-7

The guide apparatus of the excavator shown complete hydraulic circuit diagrams, description of systems and methods for troubleshooting, description (with photos) analysis of mechanical parts.
Quality - the original e-mail, the original manuals in English!

I draw your attention to the fact that the name of art is composed as follows: the first letter, for example R - type of technique, R - excavator, then the number - Capacity, the last letter - wheeled Here the most important, such as R130W-3 is 1.3 tons, but there are other Writing - 1300W-3, and it's the same thing, I checked on the example of several excavators.
