Water‑Separating Fuel Filter
Fuel is flammable and explosive. Ensure that the key switch is off and the lanyard is positioned so that the engine cannot
start. Do not smoke or allow sources of spark or open flame in the area while servicing. Keep the work area well ventilated
and avoid prolonged exposure to vapors. Always check for leaks before attempting to start the engine, and wipe up any
spilled fuel immediately.
Water entering the fuel injection system will cause corrosion and rusting of the injectors and other components, disabling the
fuel injection system. Check daily for water in the water‑separating fuel filter and have the engine inspected immediately if
there is evidence of water in the fuel system.
