Handling equipment of fuel system devices

The common rail fuel injection system (CRI)
consists of more precise parts than the parts
used in the conventional fuel injection pump and
nozzle. If foreign material enters this system, it
may cause a failure. Use special care to prevent
entry of the foreign material when servicing the
fuel system.
Use care for working environment
Avoid filter change or repairing the machine in
rain or high winds, or at places where there is a
lot of dust.
Sealing openings
Plug the pipes and the openings of the
components which are removed with the caps,
tapes, vinyl bags, etc. to prevent foreign material
from entering. Never perform repair works under
the condition that the openings are left as they
are or plugged with cloths as foreign material
may enter or environment may be polluted by
the oil leaked. Do not discard the waste oil
somewhere or other. Hand it over to your
customer for disposal, or dispose it by yourself.
How to clean parts when dirt is stuck
If any dirt or dust sticks the parts of the fuel
system, clean it off thoroughly with clean fuel.
Precautions for replacing fuel filter cartridge
Be sure to use the Komatsu genuine fuel filter
cartridge.
The common rail fuel injection system (CRI)
consists of more precise parts than the parts
used in the conventional fuel injection pump and
nozzle. In order to prevent foreign material from
entering this system, the filter employs a
specially high performance of filter element. If a
filter element other than the genuine one is used,
the fuel system may have a failure. Accordingly,
never use such a filter element.
