With an MC 25-4 parked in the bay and its hydrostatic pump due out before second shift, you want this 241-page Manitou repair manual PDF (OEM 647659EN) open on the bench; it covers nine lift trucks across the MC 18-2 to MC 30-4 and MSI 25 to MSI 35 diesel series. Hydraulics and electrics fill over half the book: wiring diagrams trace circuits to the ECU, and hydraulic schematics map oil from pump through valve block to the lift and tilt cylinders. Transmission work gets its own schematic, and the mast chapter covers rollers, wear plates, lift chains and removal. Fill the hydraulic tank to 66 L, and match the engine sump to the model: 6 L on an MC 18, 8.3 L on MC 25, MC 30 and MSI trucks. A guessed adjustment costs you a second teardown. Bookmarked and text-searchable, the PDF is bought once and stays yours for every hour this truck logs.
