The Komatsu PC75UU-2 operator manual PDF (OEM ID SEAM005600) takes this compact hydraulic excavator from walkaround to shutdown across 219 pages, including transport and cold weather running. Operation fills the largest share of the book: every gauge and warning lamp explained, rubber track handling, trailer loading, escaping from mud, and a list of symptoms that are normal, so you don't hunt for faults that aren't there. Maintenance takes nearly a third, built on a schedule chart from the initial 250-hour service through 4000 hours, plus separate intervals for hydraulic breaker work and a temperature chart for fuel, coolant and oils. Fill the engine oil pan to 9.0 L, and set fan belt deflection at 8 mm (0.3 in) under 6 kg (13 lb) of thumb pressure. A missed grease interval costs you a seized pin. Bookmarked and text-searchable, the PDF prints clean, so the service pages can live on the bench and collect grease.
