Before the R 922 swings its first bucket of the shift, you will be walking the inspection tour and checking track tension, and this 300-page Liebherr R 922 operator manual PDF (ID 11824095) is the hydraulic excavator's own guide to both. Maintenance fills more than a quarter of the book: the inspection and maintenance schedule, filling quantities and lubrication chart, slewing gearbox oil checks and Z System bucket tooth changes. Service code tables and fault, cause and remedy charts sort diesel, hydraulic, travel gear and electrical complaints; the control chapter handles quick coupler use, load lifting and the overload warning system. Fill the diesel engine with 26.4 L of oil, and run mineral hydraulic oil 3000 h between changes, or 6000 h with oil analysis. A remembered torque figure is how bolts let go. Bookmarked and text-searchable, the PDF shows you the oil grades and filter intervals before you order, so the first delivery is the right one.
