SERVICE PROCEDURE
4-55
Prepare a filter wrench and a container to catch the fuel.
1. Open the inspection cover at the bottom of the fuel tank.
2. Close fuel tank valve (1).
3. Open up the engine side cover on the left side of the
machine.
4. Put a container under filter cartridge (4) to receive drained
oil.
5. Disconnect connector (2) from the water separator lamp.
6. Turn transparent cap (3) to the left with a filter wrench.
(This cap is to be used again, so replace it with a new one
if there is any damage on it.)
7. Using a filter wrench, turn cartridge (4) to the left to remove
it.
8. Clean the filter base, and coat with oil the contact face of a
new filter with the packing.
9. Install a new filter cartridge without t fuel.
When installing the cartridge, turn it by 3/4 of a turn after
the packing comes to contact with the filter base sealing
face.
If the cartridge is tightened too tightly, the packing can be
damaged, causing fuel to leak. On the other hand, if it is
tightened loosely, fuel can also leak through a clearance
between the packing and the base. Therefore, be sure to
follow the specified tightening angle.
10. Fix earlier removed cap (3) to the base of a new filter car-
tridge.
At that time, be sure to replace the seal ring with a new
one.
