Book WDL2001-OE, the 188-page Link-Belt 2800, 3400 operator manual PDF, takes both hydraulic excavators from pre-start walkaround through travel, transport and storage. Electric and hydraulic circuit diagrams sit in the specifications chapter, so you can trace a dead switch or a sluggish function back through the system. Inspection and maintenance runs to more than a quarter of the book: the check list, the lubrication and element chart, swing and travel unit service, track shoe bolt torque and a troubleshooting section. The operation chapter maps every console switch, monitor lamp and lever. Change the fuel filter element every 500 hours and the pilot, return and drain filters every 1,000; main relief should read 4550 ± 70 PSI standard and 4980 ± 70 PSI in power up. Every hour your excavator sits parked is an hour the crew can't bill. Bookmarks jump to each chapter, and the pages print clean enough to take to the bench and get greasy.
