(water, dust, etc.) from the fuel tank bottom.
3) Drain until fuel with no water and dust flow out. Then
tighten the drain plug firmly.
(2) Draining of the oil/water separator
Drain off the oil/water separator whenever there is a lot of
drain collected in the oil/water separator at the bottom of
the cup even if not the time for periodic inspection hour.
The cup of the oil/water separator is made from semi-
transparency material and in the cup, the red colored float
ring, which rises on the surface of the drain, is installed to
visualize the amount of drain. Also, the oil/water
separator with sensor to detect the drain for warning
device on a control panel is provided as the optional.
Drain off the oil/water separator in the following manner.
1) Prepare a waste oil container.
2) Close the fuel cock.
3) Loosen the drain cock at the bottom of the
oil/water separator, and drain off any water collected
inside.
4) Tighten the drain cock with hand.
5) Be sure to bleed air in the fuel system.
NOTE:
If no drain drips when the drain cock is opened, loosen the air bleeding bolt on the top of the oil / water
separator by turning counter-clockwise 2 3 times using screw driver.
(This may occur in case of the oil/water separator position is higher than the fuel oil level in the fuel tank).
After draining, be sure to tighten the air bleeding bolt.
