FORWARD:

• This service manual has been compiled for engineers engaged in sales
  service, inspection and maintenance. Accordingly, descriptions of the
  construction and functions of the engine are emphasized in this manual
  while items which should already be common knowledge are omitted.
  One characteristic of a marine diesel engine is that its performance in a
  vessel is governed by its applicability to the vessel’s hull construction
  and its steering system.
• Engine installation, fitting out and propeller selection have a substantial
  effect on the performance of the engine and the vessel. Moreover, when
  the engine runs unevenly or when trouble occurs, it is essential to check
  a wide range, of operating conditions-such as installation on the hull
  and suitability of the ship’s piping and propeller-and not just the engine
  itself. To get maximum performance from this engine, you should completely
  understand its functions, construction and capabilities, as well as
  proper use and servicing.
• Use this manual as a handy reference in daily inspection and maintenance,
  and as a text for engineering guidance.
