Cleaning Fuel Filter Bowl

Before supplying fuel, clean the fuel filter bowl.

If dirt or any other foreign matter is included in fuel, the
filter element may be clogged earlier or water may be
more likely to remain in the filter.

If water remains in the fuel filter bowl, clean or replace
the fuel filter bowl as early as possible.

Cleaning

1. Change the carburetor fuel valve from the

"RUN"

(OPEN)

position to the

"STOP" (CLOSE)

position.

2. Loosen the ring screw and remove the fuel filter bowl.
3. Remove the element and rinse it with gasoline. If the

element is excessively dirty, replace it.
