Do not use a fuel filter with a scratch
or dent.
* Otherwise, damage to the filter or fuel leak may
occur, which causes a fire or environmental
pollution due to fuel flowing outside of the
facility.
Do not use a filter wrench when
installing the fuel filter.
* It may cause a dent or damage to the fuel filter.
If fuel spills out while removing the
fuel 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 fuel must be
discarded in according with the local laws and
regulations as well as the manufacturer's SDS.
Check the specification of the fuel
filter when installing it.
* The fuel filter of which specification does not
apply to the fuel may cause damage to the
devices.
Never cut the seal of the fuel control
link.
* If you cut the seal, damage to the engine or
deterioration in the exhaust properties may
occur.
* In case that the seal is cut, warranty will
become invalid.
Make sure there is no looseness or
play at the fuel control link.
* Otherwise, the engine may overrun.
When checking the fuel control link,
do not insert your finger into the
moving parts.
* Otherwise, you may get injured.
Check for loose bolts on the high
pressure fuel injection pipe clamp.
* If looseness or play is detected at the clamp for
the high pressure fuel injection pipe, damage to
the pipe may occur and cause a fire.
Install the clamp for the high pressure
fuel injection pipe at the correct
position.
* If it is installed at a wrong position, the pipe may
be damaged, which causes a fire.
Do not touch hot engine oil or parts.
* Otherwise, you may get burned.
Do not discard waste oil into
sewerage, river, lake, or other similar
places.
* Be sure to discard waste oil in accordance with
the applicable laws and regulations.
Conduct analysis of the engine oil
periodically and make sure that the
engine oil does not show milky color.
* If the engine oil shows milky color, water may
be mixed into the engine oil system due to
coolant leak or a damaged cylinder liner O-ring.
Continued use of the engine without any
remedy may cause seizure of the crankshaft
and lead to serious damage to the devices.
