Engine Oil - Refill
Engine Oil Level - Check
<Oil Filter - Replace>
Be sure to install the oil filler cap after
engine oil is refilled.
* Otherwise, seizure due to insufficient oil or
environmental pollution due to engine oil
flowing out from the facility may occur.
Make sure that engine oil is not
leaking from the oil pan. When
checking the engine oil level, wear
protective glasses to prevent engine
oil from getting in your eyes.
* If engine oil gets in your eyes, it may cause pain
and lead to sight loss at the worst.
Refill engine oil enough to raise the
level to within the specified range
(between the highest line {H} and the
lowest line {L}).
* If the engine oil level exceeds the upper limit,
the oil pan may crack or oil may splash out from
the breather.
* If the engine oil level is too low, seizure of the
bearings may occur.
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 checking
the engine oil level.
* It may cause a fire.
When replacing the oil filter, do not
pour the remaining engine oil in the
old filter into the new filter.
* Otherwise, foreign particles may enter the
engine oil system, which causes damage to the
devices.
Before replacing the oil filter, make
sure that the engine has cooled down
to the normal temperature.
* Otherwise, you may get burned by heat.
Use a genuine oil filter.
* Using non-genuine parts may cause damage to
the devices or degradation in the performance.
* Failures or damages caused by using non-
genuine parts will be outside the scope of the
warranty.
If paint or other matter is adhering
around the sealing surface, remove
them before assembling.
* If paint or other matter is stuck on the sealing
surface, fuel may leak through the gap, which
causes a fire.
If engine oil spills out while removing
the oil filter, wipe off with a waste
cloth.
* Otherwise, it may cause a fire or environmental
pollution due to fuel flowing outside of the
facility.
* The waste cloth used to wipe off engine oil must
be discarded in according with the local laws
and regulations as well as the manufacturer's
SDS.
