fuel.
3. Take out the element, and rinse it with diesel fuel.
4. After cleaning, reinstall the fuel filter, keeping out of

B 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
maintenance, or cleaning.
A Contact with engine oil can damage
your skin.
Put on gloves when handling engine
oil. If you come in contact with
engine oil, wash it off immediately.

placed on gradients, oil quantity can not be
measured accurately.

PERIODIC SERVICE
A Do not operate a diesel engine when engine oil is
overfilled. This can effect the air intake system which
could result in engine damage or malfunction.
C Checking 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.
(1) Oil port
(2) Oil level gauge
4. If the oil level is too low, remove the oil port, and add
new oil to the prescribed level.
5. After adding oil, wait more than 5 minutes and check
the oil level again. It takes some time for the oil to
drain down to the oil pan.
6. If the engine is operated with the oil level nearing the
lower limit, the oil may deteriorate more quickly than
normal, therefore, keeping the oil level near the
upper limit is recommended.
