MAINTENANCE
NOTICE
When filling the filter cartridge with fuel, do not re-
move cap (B). Always fill with fuel from small
holes (A) (8 places) on the dirty side.
After filling with fuel, remove cap (B) 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, center
portion is the clean side, so do not remove cap (B)
when filling with fuel. Be careful not to let dirt or
dust get into the center portion on the clean side.
12. When installing the cartridge, tighten it until the packing surface contacts the sealing surface of the filter
head, then tighten it 1/2 to 3/4 turn.
REMARK
If the filter cartridge is fastened too much, the packing will be damaged and this leads to leakage of fuel. If
the filter cartridge is too loose, fuel will also leak from the packing. Therefore, be sure to observe the tight-
ening angle.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
13. Check that drain valve (2) is closed securely.
14. Remove the plastic bag wrapping connector (5), then connect connector (5).
REMARK
If water gets on connector (5), the sensor may mal-
function and the water separator caution lamp may
light up. When removing connector (5), be extremely
careful not to let water attach to the connector.
If water sticks to connector (5), dry it completely be-
fore connecting it.
15. Turn valve (1) at the bottom of the fuel tank to OPEN posi-
tion (O).
