11. 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 center. Always fill with fuel
from the 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
(B) when filling with fuel. Be careful not to let dirt
or dust get into the center portion on the clean
side.
12. After the packing surface reaches the sealing surface of the filter head, tighten the filter cartridge 3/4 turns.
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. Be sure to observe the tight-
ening angle.
• When tightening by using a filter wrench, be extremely careful not to dent or damage the filter.
13. Confirm that the drain valve (3) at the bottom of the transparent cup (4) is tightened securely.

pump it in and out until the movement becomes
heavy.
REMARK
• It is not necessary to remove the plugs at the fuel
prefilter head and at the fuel main filter head.
• When the engine runs out of fuel, use the same
procedure to operate the feed pump (6) and bleed
the air.
