REPLACE FUEL FILTER CARTRIDGE
WARNING
● The parts are at high temperature immediately after the
engine has been operated. Wait for all parts to cool down
before replacing the filter.
● Do not bring fire or sparks near the fuel.
Prepare a filter wrench and a container to catch the fuel.
Use a genuine Komatsu filter cartridge.
1. Set the container to catch the fuel under the filter cartridge.
2. Using a filter wrench, turn filter cartridge (1) counterclockwise
to remove it.
3. Clean the filter holder, fill a new filter cartridge with clean fuel,
coat the packing surface with engine oil, then install it to the
filter holder.
4. After bringing the packing surface into contact with the seal
surface of the filter holder, tighten it a further 1/2 turns.
If the filter cartridge is tightened too far, the packing will be
damaged and this will lead to leakage of fuel. If the filter car-
tridge is too loose, fuel will leak from the packing, so tighten it
carefully.
5. After replacing the fuel filter cartridge, bleed the air from the
system. Bleed the air as follows.
6. Fill the fuel tank with fuel (to the position where the float is at
the highest position).
