10. Clean the filter head, fill the new filter cartridge with clean fuel, thinly apply oil to the packing surface, then
install it to the filter head.
NOTICE
• When filling the filter cartridge with fuel, do not re-
move the cap (B) at centre. Always fill with fuel
from small holes (A) (8 places) on the dirty side.
• After filling with fuel, remove the cap (B) at centre
and install the fuel filter.
• Always fill with clean fuel. Be careful not to let any
dirt or dust get into the fuel. In particular, centre
portion is the clean side, so do not remove the cap
(B) when filling with fuel. Be careful not to let dirt
or dust get into the centre portion on the clean
side.
11. When installing the filter cartridge, tighten it until the packing surface contacts the sealing surface of the
filter head, then tighten it 1/4 to 1/2 turns.
REMARK
If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If
the filter cartridge is tightened too loose, fuel will also leak from the packing, so always tighten to the speci-
fied angle.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
12. Check that the drain valve (3) is tightened securely.
13. Remove the plastic bag which wraps the connector (5), and connect the connector (5).

malfunction and the water separator caution lamp may
light up. When removing the connector (5), be ex-
tremely careful not to let water get on the connector.
• If water gets on the connector (5), dry it completely
before connecting it.
