ENGINE OIL
â– Engine oil
Be sure to drain water from fuel, and
pay attention that coolant or other
water will not get mixed with fuel.
* Otherwise, rust could form on the plunger,
which could interfere engine stopping or cause
flue explosion, dilution, or water hammering.
Do not remove the strainer while
filling the fuel tank.
* Otherwise, foreign particles could enter and
cause damage to the fuel pump.
When using fuel from a storage tank,
leave it to sit for more than 24 hours
so that dust and water can settle at
the bottom. Then, use the upper clean
fuel.
* Otherwise, clogging of the filter may occur,
which could cause decrease in the output
power.
* Depending on the specification of the tank,
prolonged sedimentation time may be required.
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 could cause 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, premature wear of
bearings and sliding parts may occur, which
could shorten the service life of the engine.
Conduct analysis of the engine oil
periodically and check to 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.
Sustained use of the engine without any
remedy could 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 bearing
could occur, which could cause seizure of the
crankshaft.
* If kinematic viscosity of engine oil increases,
fuel consumption will increase.
