Checking of the cooling water strainer

Each day, prior to starting the engine, make sure that the

cooling water strainer is not clogged by dirt. Close the

raw water seacock and remove the cover from the filter

housing for proper inspection.

Cleaning of the cooling water strainer

Clean the filter element at least twice a year, or whene-

ver necessary. If the cooling water strainer gets clogged

up, the cooling liquid in the engine may overheat.

When closing the strainer gain, make sure that the cover

is perfectly shutting the unit off. If and when air is suc-

ked into the system, on account of a badly closing filter

cover, there is a severe risk of overheating of the engine.

Again: make absolutely sure that the cover fits the strai-

ner housing well and without any air leaks!
