Check Engine Oil Level
--- every 10 hours (before starting the engine)
IMPORTANT: Incorrect engine oil level may cause engine
problems (The oil level should be between the upper
and lower marks on oil level gauge (1)).
If engine oil level is too high, control the oil level to the
proper quantity before starting the engine.
Check oil level before starting the engine. Pull out oil level
gauge (1). Check for mixing of foreign matter or contamination
in the oil. Wipe oil level gauge (1) with cloth, re-insert it into
the pipe to the end, and then pull it out again. The oil level
should be between the upper and lower marks on oil level
gauge (1).
If oil level is below the lower limit mark, add the recommended
engine oil via oil filler (2).
If oil level exceeds the upper limit mark, remove drain plug (3),
and then drain oil.
Recheck oil level.

NOTE: Level the engine when adding oil or inspecting oil
level.
When required to check oil level after operating the machine,
first stop the engine. Wait for more than 15 minutes. Then
check oil level.
(This means that the oil level will become stabilized after all
oil delivered to respective lubrication area returns to the oil
pan.)
If the oil color changes, severe contamination and/or mixing
of foreign matter may be seen, change the oil.

WARNING: Do not spill oil while changing oil. Spilled
fuel and oil, and trash, grease, debris, accumulated
coal dust, and other flammable materials may cause
fires.
