ENGINE OIL
■ Engine Oil
■ Handling Engine Oil
Refer to the Engine Oil Properties
table in this Operation & Maintenance
Manual, and even if one item exceeds
the limit, the engine oil must not be
used.
* Otherwise, seizure of the sliding parts may
occur, which causes serious damage to the
devices.
Use the genuine engine oil specified
in this Operation & Maintenance
Manual.
* Otherwise, seizure of bearings, breakage of a
valve, sticking of a piston ring, seizure between
a ring and a cylinder, or premature wear of
bearings and sliding parts may occur and
shorten the service life of the engine.
Conduct analysis of the engine oil
periodically and make sure that the
engine oil does not show milky color.
* If the engine oil shows milky color, water may
be mixed into the engine oil system due to
coolant leak or a damaged cylinder liner O-ring.
Continued use of the engine without any
remedy may cause seizure of the crankshaft
and lead to serious damage to the devices.
Keep the quantity and properties
(viscosity) of the engine oil at the
specified level.
* If the supply or kinematic viscosity of engine oil
is too low, insufficient lubrication of the
bushings may occur and cause seizure of the
crankshaft.
* If kinematic viscosity of engine oil increases,
fuel consumption may increase.
Keep away from fire, when working
with flammable substances such as
engine oil.
* They may cause a fire.
Do not operate the engine with fuel or
water mixed in the engine oil.
* Otherwise, viscosity of engine oil may
decrease, which causes seizure of the bearings
or other serious accidents.
Do not store engine oil in a poorly
ventilated place.
* Otherwise, built-up volatile engine oil may be
exposed to a flame, which causes an explosion
or a fire.
Wipe off spilled flammable
substances such as engine oil
thoroughly with a waste cloth.
* They may cause a fire.
When discarding a waste cloth used
to wipe off combustible material, put
it into a lidded can and obey the
Waste Management and Public
Cleansing Act to handle it as a special
industrial waste.
* It may cause a fire.
* It may cause environmental pollution.
* If you violate rules, you may be subject to
penalties.
When handling engine oil, obey the
manufacturer's SDS.
* If engine oil gets in your eyes, it may cause pain
and lead to sight loss at the worst.
Do not breathe in volatilized engine
oil.
* Otherwise, it may be hazardous to your health.
When storing engine oil in the
container, be sure to close the cap.
* Otherwise, built-up volatile engine oil may be
exposed to a flame, which causes an explosion
or a fire.
