[5] CHECKING/CLEANING FUEL FILTER POT
• The fuel filter pot has fuel (diesel oil) inside. Be extremely careful of fire such as cigarette when
cleaning the water separator pot.
• If the fuel spills when the fuel filter pot is removed, thoroughly wipe it off.
CAUTION
• Water or dust accumulated inside the fuel filter pot will cause engine failure. Check inside the
pot and remove any water or dust accumulated inside.
• If water remains in the fuel filter pot, it is assumed that much water is also mixed in the fuel
tank. See “Maintenance 8.7 Maintenance for Every 50 Hours” and eliminate water and dust
mixed into the fuel tank.
