What This R920 Manual Actually Covers

The Product Description section identifies the R920’s main groups – uppercarriage with diesel engine, control valve block, radiator, air filter, slewing gearbox, hydraulic tank and pump; undercarriage with travel gearbox, carrier and track rollers, idler-wheel and rotary connection – and lists whole-body and hand/arm vibration emission data measured to ISO 5349-1:2001 and ISO/TR 25398:2006 for both crawler and wheeled excavator work cycles.

The factory specification sheet included in the manual states the R920 runs a 110 kW / 150 HP diesel engine meeting Stage IIIA / Tier 3 emissions, with an operating weight of 21,000-21,500 kg and a bucket capacity range of 0.60-1.25 m³.

The Control and Operation chapter is the largest section of the book. It walks through the operator’s platform layout and Control unit B, the full display and menu system (status symbols, main menu, operating status, general and machine-specific settings, information and tool-control menus, messages), and every stage of running the machine: pre-service inspection, refuelling, starting the diesel engine, sensor-controlled low idle automatic, travelling and braking, driving on slopes, controlling the working attachment, turning and braking the uppercarriage, and the optional overload warning system. Separate procedures cover operating a special working attachment both with and without a mini-joystick. General working methods address safe practice with a backhoe bucket, grading, a hydraulic hammer, grapple and clamshell, plus transferring and lifting loads (including with a quick coupler or a load-lift hook), installing and removing buckets and grapples, driving the machine onto a low-loader and tying it down for transport, and emergency procedures including emergency operation mode, jump-starting, the optional central lubrication system, and towing.

The Malfunctions chapter gives service code tables for warning symbols shown on the display (hydraulic oil level and temperature, fuel level and temperature, fuel pressure thresholds, coolant level, and more), each with its effect and remedy, plus fault-cause-remedy tables organised by system and a fuses-and-relays problem-remedy section.

The Maintenance chapter is where this Liebherr R920 manual earns its keep for anyone servicing the machine. It opens with the full inspection and maintenance schedule (on handover, every 8-10, 50, 500, 1000 and 2000 hours, plus special intervals), then gives the recommended lubricants and fluids table with exact quantities: Liebherr Motoroil 10W-40/5W-30 for the diesel engine at 26.4 l, hydraulic system content/change/tank volumes of 330 l / 108 l / 139 l using Liebherr Hydraulic Basis 100, HVI or Plus Arctic oil, 4.6 l Liebherr Gear Basic 90 LS for the slewing gearbox, 2 x 4.3 l for the travel gearboxes, a 593 l diesel fuel tank, 47 l of Liebherr Antifreeze coolant, and 8.6 l of windscreen washer fluid. Detailed procedures follow for checking and changing oils, draining fuel and hydraulic tank sediment, cleaning or replacing air filter cartridges, checking coolant concentration, checking track tension (with the 25 ±5 mm sag specification) and tightening or slackening the track, checking track pad and sprocket wheel mounting bolts against listed test and pre-tightening torque values, lubricating the working attachment and changing bucket teeth with the Z system, and servicing the cab air filter, air conditioning and slewing gearbox. The closing appendix explains the initial torque and tightening-angle procedure for the track pad, sprocket, travel gear mechanism and travel motor mounting bolts, and the manual finishes with a full alphabetical index for fast lookup.
