Fluid grades for each ambient temperature, the lubrication chart, and what the emergency bypass does when a switch fails: the Link-Belt LS-2800 operator manual PDF settles them for this LS-series hydraulic excavator in 112 pages, Book No. WDL2802-5E. Inspection and maintenance fills close to a third of the book, with a check list keyed to the hour meter, periodic and irregular service, and troubleshooting charts that match your symptom to a likely cause. Hydraulic system and electric circuit diagrams sit with the instruments and operation modes, and the back section covers hammer installation, oil flow control and the long front relief valve settings. Fill each lower roller with 190cc (6.3oz) and the take-up roller with 170cc (5.5oz); the pilot pump relief valve setting is 569 psi (40 kgf/cm²). A roller refill stalls when nobody knows the volume. Bookmarks and a live text layer take you straight to the page with the answer.
