The machines equipped with 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.
Select an appropriate workplace
Avoid the work of adding hydraulic oil, replacing filters, or repairing the machine in rainy or windy weather, or in
dusty environment.
Sealing the opening
Plug the removed pipes and the openings of the removed components with the caps, tapes, plastic bags, etc. to
prevent foreign material from entering.
NOTICE
Do not expose the openings or stuff it, otherwise foreign
material may enter or leaked oil may pollute the environ-
ment.
Do not discard the oil inconsiderately. Ask the customer
for disposal or bring it back to dispose it appropriately.
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.
NOTICE
The machine equipped with 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 oth-
er than a Komatsu genuine filter is used, fuel system contamination and damage may occur. Therefore
Komatsu recommends using only Komatsu fuel filters and install them following the procedures in the
shop manual.
