WARNING
• After the engine stops, all parts are still very hot, so do not replace the filter immediately. Wait for all
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.
• When opening the air bleeding plug of the fuel filter head, take care. There may be remaining pres-
sure and fuel may spurt out.
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 inspection and maintenance of the fuel system, be careful not to let any foreign
material get in, more than ever before. If dust sticks to the fuel system, wash it off thoroughly with
fuel.
Items to be prepared
• Container to catch the drained oil
• Filter wrench
