4.3.5 Checking oil level
4.3.6 Checking coolant level
ŸWarning: Avoid skin or eye contact with coolant to prevent personal injury.
ŸWarning: At operating temperature, engine coolant is hot and under pressure, and the coolant steam can
cause personal injury. Do not remove the pressure cap on the radiator until the engine has been stopped and
coolant temperature has dropped below 50
. Slowly loosen the cap to release the cooling system before
checking coolant level or making supplement.
For non- vehicle application
Check the coolant level daily.
(1) Slowly loosen the pressure cap on the radiator to release pressure before starting the engine or until coolant
temperature goes below 50ć after stopping the engine.
(2) Remove the pressure cap and check coolant from the filler or inspection port. The coolant level should remain
between the marks in the radiator or expansion tank, or meet the requirement of equipment manufacturer.
(3) Supplement if necessary. Coolant should be added near the upper mark or meet the requirement of equipment
manufacturer.
Caution: Coolant should be added slowly to avoid air block.
For vehicle application
Check the coolant level daily. It should remain between the
marks MAX (high level) and MIN (low level) in the expansion
tank, and add it if necessary. Coolant should be added near
the upper mark (MAX). Make supplement
When nessecary.

Check the oil level daily before starting the engine or the
engine is in stop (at least 10 minutes after being stopped) to
provide enough time for oil to flow back to the oil pan. The oil
level should be between the upper mark (high oil level) and
lower mark (low oil level). If oil is not enough, supplement it.
The oil volume difference between the upper and lower marks
is about 6 L for SC10E engine (10L) and 8 L for SC12E engine
(12L).
Caution: Do not run the engine when the oil level is
below the lower level, otherwise it can result in poor
engine performance, or even damage to the engine. But
the oil level should not exceed the high level mark.
