Within the hour you could be greasing bucket pins and inspecting rubber shoes on a hydraulic excavator with this 162-page Kobelco SK25SR, SK30SR, SK35SR operator manual PDF (OEM ID S3PW0003E-00) open on the seat beside you. Maintenance takes up more than a quarter of the book. Its lubrication charts and service schedules run from the 8-hour daily check through the 50, 250, 500 and 1,000-hour visits to the 2,000-hour service. Each of the three models gets its own oil viscosity and capacity table, next to torque tables for hydraulic hoses, joints and capscrews, while the operating chapters explain the monitor panel, every switch and lever, and how to remove and install rubber shoes. Clean the hydraulic tank suction strainer every 2,000 hours and tighten it to 12 ± 1 kgf·m (87 ± 7 ft·lbs). Every hour the machine sits, your crew sits with it. Bookmarks and a text layer take you from the index to the interval chart you want in seconds.
