The new PR 776 has exceptionally long change intervals for operating fluids such as hydraulic or engine oil. Depending on the nature of the work, and provided that regular checks are performed, the change interval for Liebherr-plus oils can be as long as 8,000 hours of operation. Centrally located maintenance points, access flaps and engine compartment doors that open to a wide angle, a tilting cab as standard equipment and, as an option, a radiator fan that can be swung out for cleaning are all features that speed up and simplify efficient servicing work.
