9. After replacing the filter cartridge, start the engine and check
that there is no leakage of fuel from the filter seal surface. If
there is any leakage of fuel, check the tightening of the filter
cartridge. If there is still leakage of fuel, follow Step 1 and 2 to

REPLACE CORROSION RESISTOR CARTRIDGE

All the engine parts are at high temperature after the engine has been operated, so never replace the cartridge immediately after
finishing operations.
Wait for the oil to cool down before replacing the cartridge.
Prepare a filter wrench
1. Turn valve (1) at the top of the corrosion resistor to close it.
2. Set the container to catch the water under the cartridge.
3. Using a filter wrench, remove cartridge (2).
4. Clean the filter holder, coat the steel surface of the new filter
cartridge with clean engine oil, then install it.
5. When installing, tighten until the gasket contacts the seal
surface of the filter holder, then tighten a further 2/3 turns.
If the filter cartridge is tightened too far, the gasket will be
damaged and this will lead to leakage of water. If the filter is too
loose, water will also leak from the gap at the gasket, so always
tighten the correct amount.
6. Turn valve (1) to open it.
7. After replacing the cartridge, start the engine and check that there is no leakage of water from the filter seal
surface. If there is any leakage of water, check the tightening of the filter cartridge.
