METHOD FOR REPLACING FUEL MAIN FILTER CARTRIDGE
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.
• While the engine is running, high-pressure is generated in the engine fuel piping.
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 using the fuel feed pump, do not loosen the air bleeding plug of the fuel circuit.
The fuel circuit is pressurized while the fuel feed pump is operated. If the air bleeding plug is loos-
ened at this time, fuel may spurt out and it is dangerous.
