(5) Checking and Resupplying Cooling Fresh Water
Check the fresh water level before operation
while the engine is cold.
Checking the water level while the engine is hot
is dangerous, and the cooling water reading will
be misleading due to thermal expansion.
Only check and resupply fresh water routinely at
the subtank. Do not remove the filler cap of the
fresh water tank during operation.
1)
Check that cooling fresh water level is in
betweer Full and Low mark on the side of
the sub-tank.
2)
If the water level is below to the Low level
mark, open the sub-tank cap and supply
fresh water.
3)
When the water in the sub-tank runs out,
open the filler cap of the fresh water tank and
supply water until it overflows from the filler
port.
(See 3. 2. 4)
(Note)
The water level rises in the sub-tank during engine operation. This is not an abnormality.
After stopping the engine, the cooling water cools down and the extra water in the sub-tank
returns to the fresh water tank.
(6) Checking the Remote Control Handle
Be sure to check that the remote control handle lever moves smoothly before use it. If it is
hard to operate, Iubricate the joints of the remote control cable and also the lever bearings.
(See 4. 3. 4 (3),(4).)
If the cooling fresh water runs out too often,
or only the cooling fresh water in the fresh
water tank falls without any change in the
water level of the sub-tank, there may be
some leakage of water or air.
In such cases, consult your Yanmar dealer
or distributor without delay.
If the shift stroke of the remote control cable is inadequate at the marine gear end,
it may be impossible to shift into either ahead or astern or clutch (marine gear)
slippage may occur.
Do not open the filler cap
during operation or imme-
diately after stopping the
engine.
Hot steam and water will spout out. To
remove the cap, wait until the engine
has cooled down, wrap the cap with a
cloth and loosen the cap slowly. After
checking, fasten the filler cap firmly.
