When you go on your way back after completing loading, you ned to change cabs. The instructions are not complete and miss two important aspects: You also may need to switch off engine run, fuel pump and generator field. Set the cutout valve to cutout and the rotar valve to freight lap. It sloppy not too mention this, on the other hand you are asked to start the engine, which sounds weird to me. Eithe, do not give any detailed instructions or make them a complete step byt step guide with all in the correct order.
