Northern Lights OLP LP445, Operator'S Manual

OLP 05/00
Servicing of marine engines and generator sets
presents unique problems. In many cases boats cannot
be moved to a repair facility. Marine engines cannot
be compared to the servicing of automobiles, trucks or
even farm equipment. Failures often occur in remote
areas far from competent assistance. Marine engines
are taxed far more severely than auto or truck engines;
therefore, maintenance schedules must be adhered to
more strictly.
Failures begin with minor problems that are overlooked
and become amplified when not corrected during rou -
tine maintenance.
As operator, it is your obligation to learn about your
equipment and its proper maintenance. This is not a
comprehensive technical service manual. Nor will it
make the reader into an expert mechanic. Its aim is to
aid you in maintaining your unit properly.
