Replace fuel pre-filter cartridge
WARNING
!
Engine is at high temperature immediately after the machine
has been operated. Wait for engine to cool down before
replacing the filter.
!
High pressure is generated inside the engine fuel piping sys-
tem when the engine is running.
When replacing the filter, wait for at least 30 seconds after
stopping the engine to let the internal pressure go down
before replacing the filter.
!
Do not bring fire or sparks near the fuel.
!
Be careful when opening the air bleed plug in the fuel filter
head. It is still under pressure, so fuel may spurt out.
NOTE
!
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.
!
The common rail fuel injection system used on this machine
consists of more precise parts than the conventional injec-
tion 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.
!
When carrying out inspection or maintenance of the fuel sys-
tem, pay more attention than normal to the entry of dirt. If dirt
is stuck to any part, use fuel to wash it off completely.
!
Container to catch the fuel
!
Filter wrench
1. Open the engine side cover on the right side of the chassis.
2. The fuel pre-filter forms one unit with the water separator
and is installed at the center of the engine.
3. Set the container to catch the fuel under the filter cartridge
(1).
4. Using the filter wrench, turn cap (2) of the water separator to
the left to remove it. (This cap is used again. If it is damaged
or broken, replace it with a new part.)
5. Using a filter wrench, turn the filter cartridge (1) to the left to
remove it.
