7. Replace the oil filter element
Replace the filter element every 200 hours
or 3 months. Make sure to use genuine
filter element.
1) Remove the fuel filter;
2) Clean the gasket surface of the filter
seat with a lint free cloth;
3) Discard the O-ring;
4) Install a new O-ring;
Note: Check whether there is an old
seal on the filter element seat. It will
cause oil leakage if the old seal is
stuck on it.
5) Fill up the new filter with clean fuel, and
lubricate the O-ring with clean engine oil;
6) Install the fuel filter as specified by the
filter manufacturer.
Note: To reduce the possibility of fuel
leakage, ensure that the fuel filter is
installed firmly but not too tightly.
Excessive mechanical tightening will
damage the fuel filter.
7) After replacing the filter element, start
the engine and check the sealing surface
of the filter element for oil leakage.
