ENGINE OIL
CAUTION
To avoid personal injury:
A Be sure to stop the engine before
checking and changing the engine
oil and the oil filter cartridge.
A Do not touch muffler or exhaust pipes
while they are hot; Severe burns
could result. Always stop the engine
and allow it to cool before conducting
inspections, maintenance, or for a
cleaning procedure.
A Contact with engine oil can damage
your skin. Put on gloves when using
engine oil. If you come in contact
with engine oil, wash it off
immediately.
A Do not operate a diesel engine when engine oil is
overfilled. This oil can drain through the air intake
system, which cause engine disacceleration and oil
leaks from breather pipings. It could result in a over-
running or oil hammering of engine in case of the
engine with suction blow-by gases breathered in.
BChecking oil level and adding engine oil
1. Check the engine oil level before starting or more
than 5 minutes after stopping the engine.
2. Remove the oil level gauge, wipe it clean and
reinstall it.
3. Take the oil level gauge out again, and check the oil
level.
