(2) Replacing Engine Lube Oil and Lube Oil filter. (See 5.2.1(1))

(3) Replacing Cooling Fresh Water

Cooling performance drops when the cooling water is contaminated with rust and scale.

Even if LLC is added, the cooling water must be periodically replaced because the properties of

the agent will degenerate. Replace the cooling water periodically.

●

Draining the Cooling Fresh Water → See 4.9.1.

●

Supplying Cooling Fresh Water → See 3.5.

(4) Inspecting and Replacing Anti-

Corrosive Zinc

and operation is continued with a

small volume of anti-corrosive zinc,

corrosion of the seawater cooling

will result.
