Within the hour you'll be greasing the LS-2700's pins against its lubrication chart and ticking down the inspection check list, and this Link-Belt LS-2700 operator manual PDF (Book No. WDL2700-1E, 106 pages) is the copy written for that LS-series hydraulic excavator. Hydraulic system and electric circuit diagrams open the operation section, followed by the instruments and controls, operation modes, one touch idle, and the emergency bypass for a failed switch. Inspection and maintenance takes up more than a third of the book, running through periodic and irregular service, troubleshooting, and fuel and lubricant grades by ambient temperature; the book then closes on selecting and installing a hydraulic hammer. Replace the hydraulic return filter element every 500 hours and the suction filter element every 2,000. Every hour parked is a crew on the clock. Bookmarked and text-searchable, your copy rides in the service truck or the cab, wherever the LS-2700 is digging.
