Part of the Yanmar Operator Manuals.
Air trapped in the fuel lines will keep one of these engines cranking all morning, and the priming procedure that clears it is laid out step by step in this manual. Yanmar published it as OATN4-EN0029, a 124-page English operator manual covering six TNV and TNM series industrial diesels: the 3TNV74F, 3TNV76F, 3TNV80F, 3TNV80FT, 3TNV88F, and 3TNM74F.
Inside are diesel fuel and engine oil specifications, fuel system priming, starting and shutdown procedures, a periodic maintenance schedule with a standard torque chart, and a troubleshooting section that covers the electronic control system and lists the possible faults of electronically controlled engines. Long-term storage procedures and full specifications for each model round it out.
Whether the engine drives a generator, a pump, or sits on a stand waiting for parts, the PDF travels with you, on a phone beside the engine or printed for the bench, with maintenance intervals and torque values in reach before anything goes back together.
