Inspection of the filter and drainage of water from the fuel tank
Check whether or not the filter element is
dirty or fouled.
In case the filter element is dirty or clogged,
please replace it with a new one, and bind
the cup firmly with the tightening ring.
If water has collected in the cup, discard the
water. Also, water in the cup means there is
water in the tank as well. Follow the instruc-
tions on page 13 and drain the water from
the fuel tank.
