3. Cleaning fuel filter [LX2610/
LX2610SU]
WARNING
T
o avoid personal injury or death:
• Stop the engine and remove the key before
checking fuel lines and fuel filter.
• Check the fuel lines periodically. The fuel lines
are subject to wear and aging. Fuel may leak
out onto the running engine, causing a fire.
• Protect your hands when using kerosene to
clean components.
This job should not be done in the field, but in a clean
place.
1. Loosen
and remove the filter bowl, and rinse the
inside with kerosene.
2. Remove the element and dip it in the kerosene to
rinse.
3. After cleaning, reassemble the fuel filter, keeping
out dust and dirt.
4. Bleed the fuel system.
(See Bleeding fuel system on page 136.)
IMPORTANT :
• When the fuel filter bowl has been removed,
fuel stops flowing from the fuel tank. If the
fuel tank is almost full, however, the fuel will
flow back from the fuel return pipe to the
fuel filter. Before checking, make sure the
fuel tank is less than half-full.
• If dust, dirt or water enters the fuel system,
the fuel pump and injection nozzles are
subject to premature wear. To prevent this,
be sure to clean the fuel filter bowl and
element periodically.
