METHOD FOR REPLACING FUEL MAIN FILTER CARTRIDGE

WARNING
• Just after the engine stops, all parts are still very hot, so do not replace the filter immediately. Wait
for all of parts to cool down before starting the work.
• 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
pressure go down before replacing the filter.
• Do not bring any open flame close.
NOTICE
• Komatsu genuine fuel filter cartridges use a special filter that has highly efficient filtering ability.
When replacing the parts, Komatsu recommends using Komatsu genuine parts.
• The common rail fuel injection system used on this machine consists of more precise parts than
those in the conventional injection pump and nozzles. If any cartridge other than a Komatsu genu-
ine filter cartridge is used, dust or dirt may get in and cause problems with the injection system.
Never use a substitute.
• When performing the inspection or maintenance of the fuel system, pay more attention than normal
to the entry of dirt. If dirt sticks to any part, use fuel to wash it off completely.
Prepare a filter wrench and a container to catch the fuel.
