REPLACE FUEL PRE-FILTER CARTRIDGE 4
WARNING
q
After the engine has been operated, all parts are at high temperature, so do not replace the filter imme-
diately. Wait for all parts to cool down before starting the operation.
q
High pressure is generated inside the engine fuel piping system when the engine is running.
When replacing the filter, wait for at least 30 seconds after stopping the engine to let the internal pres-
sure go down before replacing the filter.
q
Do not bring any fire or flame close.
NOTICE
q
Genuine Komatsu fuel filter cartridges use a special filter that has highly efficient filtering ability.
When replacing the filter cartridge, always use a genuine Komatsu part.
q
The common rail fuel injection system used on this machine consists of more precise parts than the
conventional injection pump and nozzle.
If any part other than a genuine Komatsu filter cartridge is used, dust or dirt may get in and cause
problems with the injection system. Always avoid using substitute parts.
q
When carrying out inspection or maintenance of the fuel system, pay more attention than normal to
the entry of dirt. If dirt is stuck to any part, use fuel to wash it off completely.
