Operation
HANDLING OF NEW ENGINE
The life and performance of an engine are
greatly influenced by how it is handled and
serviced during the initial period.
Operate the engine by observing the follow-
ing precautions during the initial 100 hours of
operation.
Cautions in operation
1. After starting, warm the engine thorough-
ly by means of warming-up operation until
the cooling water temperature rises above
50°C (122°F)
2. Never attempt to race the engine under
non-loaded conditions
3. Always maintain the operation speed of
the engine below 70% of the maximum
engine rpm.
4. Avoid overloading.
ENGINE HANDLING PRECAUTIONS
When handling the engine, be sure to
observe the following precautions.
When Starting the engine
1. Check the engine oil and coolant level
and refill if necessary.
2. After the engine starts, make sure that the
oil and charge warning lamps are off.
3. Warm up the engine until it runs smoothly,
emitting normal exhaust gases.
4. During this warming up operation or
when the cooling water the cooling water
temperature is still low, never attempt to
race the engine.
During engine operation
1. During operation, always make sure that
the cooling water temperature and lubri-
cating oil pressure are both normal.
Normal cooling water temperature is 75
to 85°C )167 to 185°F)
Oil pressure is normal if the “OIL” warn-
ing lamp remains OFF during engine
operation.
2. Always be aware of the condition of the
engine, paying attention to any abnormal
vibration, noise or other unusual circum-
stances. If any abnormality is found,
immediately stop the operation, examine
the cause, and make the necessary correc-
tion.
When Stopping the engine
Upon completion of operation, idle the
engine for some time to lower its temperature
before stopping this procedure will help to
extend the engine life.
Note that stopping the engine immediately
after heavily loaded operation will deterio-
rate the engine because it is still in a very hot
state.
Others
Perform periodical inspection and replace-
ment of the following items:
Engine, oil, oil filter, air cleaner element, fuel
filter element.
