WARNING
q
When the engine is stopped, all parts are at high temperature, so do not replace the filter immediately.
Wait for all parts to cool down before starting the work.
q
High pressure is generated inside the engine fuel piping system when the engine is running.
Wait for at least 30 seconds after stopping the engine to let the internal pressure 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, Komatsu recommends using 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 nozzles. If any part other than the genuine Komatsu filter cartridge is
used, dust or dirt may get in and cause problems with the injection system. Always avoid using sub-
stitute parts.
q
When carrying out inspection or maintenance of the fuel system, pay more attention than normal to
the entry of dirt.
q
Prepare a container to catch drain oil.
q
Prepare a filter wrench
1. Turn the valve (1) at the bottom of the fuel tank to the
CLOSE position (S).
2. Open the cover on the right side of the machine.
3. Set the container to catch the fuel under the filter cartridge.
4. Using a filter wrench, turn filter cartridge (2) counterclock-
wise to remove it.
q
After removing the filter cartridge, fuel drops fall down
from the filter head.
In order to prevent flow out of the fuel, be sure not to
leave the machine without the filter cartridge.
5. Clean the filter holder, coat the packing surface of the new
filter cartridge lightly with oil, then install the filter cartridge
to the filter holder.
Replace inner seal (3) with a new part.
