Instructions
1)
Make sure that the Kingston Cock is open.
2) Make sure there is enough lube oil and (fresh) cooling
water
3)
Operate the remote control handle and check if the
devices connected to the engine side work property
1)
When the lube oil temperature is raised to allow the
engine
to
start, the pilot lamp goes off.
2)
When the engine is started, check the following:
• them is
no
water and no oil leakage.
• gas does not leak when the engine is started.
• there are no abnormal indications on the instrument
panel.
• there
is
no abnormality in cooling water discharge,
engine vibrations.
or
engine sounds.
3) To warm
up
the engine, operate
at
low
revolutions for
about 5 minutes, then raise the revolutions to the rated
rpms and !hen to max. rpms.
1)
Do not operate the engine
at
full load yet, but raise the
rpms gradually for about 10 minutes until they reach
rated rpms.
2) Make sure that exhaust color and temperature are normal.
3) Check the instrument panel and see
if
the water
temperature and oil pressure are normal.
1)
Before stopping the engine, operate
it
at
650· 700 rpms
!or about 5 minutes.
2)
Raise engine rpms to 1,800 just before stopping the
engine and idle the engine for about 3-4 seconds.
1 ) Check again for water and oil leaks.

Precautions
3)
Lamp
should
go
off
when
engine
is
running.
2)
• Fit leaks
if
any.
• Check the intake/exhaust valves,
FO. injection valve. and cylinder
head.
3} Do not raise the engine revolutions
abruptly,
1) Stopping the engine suddenly during
high speed operation increases the
temperature
of
engine parts.
2)
This procedure prevents carbon from
being deposited on the valve seats,
etc.
1 } Check the oil sea! area.
2)
Especially the engine installation
bolts.
4) Drain from the sea water pump.
