MAINTENANCE PROCEDURE
1.
Open the rear right cover (1)
2.
Turn the valve (2) to CLOSE position (S).
3.
Place a container under the fuel prefilter cartridge to catch
the fuel.
4.
Loosen the drain valve (3) and drain water and sediments
from transparent cup (4), and also drain all the fuel from fil-
ter cartridge (5).
5.
Turn the transparent cup (4) counterclockwise to remove it
by using the filter wrench.
This cup is used again.
6.
Turn the filter cartridge (5) counterclockwise by using the
filter wrench, and remove it.
7.
Place a container under drain hose to receive the water.
8.
Install the currently removed transparent cup (4) to the bot-
tom of the new filter cartridge.
Replace the OR (6) with a new one.
When installing the transparent cup, thinly apply oil to the
packing surface, contact it to the sealing surface of filter
cartridge (5), and then tighten it 1/4 to 1/2 turn.
If the transparent cup is fastened too much, the O-ring will
be damaged and this leads to leakage of fuel. If it is too
loose, fuel will also leak from gaps of the O-ring. Be sure
to observe the tightening angle.
When applying the grease, be careful not to allow the grease to adhere to the water drain port (7) and
threaded part (8) of the drain valve.
9.
Clean the filter head.
10. 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). Always fill with fuel from small
holes (A) (8 places) on the dirty side.
•
After filling with fuel, remove the cap (B) and in-
stall 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.
When installing the cartridge, tighten it until the packing surface contacts the seal surface of the filter holder,
then tighten it 3/4 of a turn.
