NOTICE
BECOME FAMILIAR WITH THE ENGINE
FAULT CODE SYSTEM. SHOULD A ENGINE
MALFUNCTION DEVELOP THE OPERATOR
WILL BE ABLE TO REACT FASTER TO THE
SITUATION.
The Cummins engine package will provide a longer life
span if the engine is correctly maintained including oper-
ating within Cummins specifi cations. Daily engine main-
tenance checks need to be performed,
The new Cummins engine package installed in your yacht
does not require a "break in" procedure. Use the vari-
ous vessel displays to constantly monitor critical engine
indicators such as oil pressure, temperature, voltage and
fault codes.
One important Cummins operation recommenda-
tion is that on new engines after the engines are
started they need to reach 140 degrees as shown
on the display unit before the engine is run hard at
higher cruising rpm's..
This permits the internal engine components to
meet the proper wear tolerances.
During daily maintenance checks listen for any unusual
system noises that may indicate immediate service.
