Removing the filter cap
Do not attempt to remove the water filter cap at the top of the fresh water tank
while the engine is running, or while the engine is still hot after it has been stopped;
otherwise, steam will escape and may cause serious injury.
If removal of the filter cap is unavoidable, place a piece of cloth over the cap and
turn the cap slowly, being sure that you will be safe even if the steam escapes.
6)
Cooling water (fresh water) level check
Check the level of the cooling water (fresh water) before daily operation.
A low cooling water level can cause insufficient pump discharge and the
accumulation of scale in the heat exchanger.
7)
Draining the water
To drain the water, open the cooling water drain cock and remove the water
filter cap.
If the filter cap is not removed, a vacuum will be created in the water jacket
and all the water will not drained.
8)
Idling the engine when stopping
Always idle the engine for ten minutes immediately after starting and prior
to stopping.
Be sure to idle the engine adequately, especially before stopping.
Stop the engine only after its temperature has dropped sufficiently.
If the engine is stopped while hot, the hot fresh water will cause the temperature
of the raw water in the heat exchanger pipe to rise, causing build-up of calcium
deposits in the pipe and a drop in the cooling affect.
