NOTICE
• When filling the filter cartridge with fuel, do not re-
move the cap (B) at center. Always fill with fuel
from small holes (A) (8 places) on the dirty side.
• After filling with fuel, remove the cap (B) at center
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 the cap

or dust get into the center portion on the clean
side.
9.
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 turns.
REMARK
If the filter cartridge is tightened too much, the packing may be damaged and this will cause the leakage of
fuel. If it is not tightened enough, fuel will leak through the gap at packing. Be sure to observe the tightening
angle.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
10. Install the drain hose.
11. Turn the valve (1) at the bottom of the fuel tank to OPEN position (O).
12. After replacing the filter cartridge, start the engine and run it at low idle for 10 minutes.
13. Check for leakage from the filter seal surface and transparent cup mounting face.
If the leakage is noticed, check the filter cartridge for its tightening condition.
If there is still fuel leakage, repeat steps 1 to 6 and remove the filter cartridge. If any damage or pinched foreign
material on the packing surface is found, replace it with a new cartridge, and repeat steps 7 to 12 to install it.
