5.4. Replacement of Fuel Filter
•
Clean the area around the fuel filter
head .
•
Remove the fuel filter by turning it
counter-clockwise with filter wrench.
(Discard the used filter.)
•
Use a clean lint free cloth to clean the
gasket surface of the fuel filter head .
•
Use clean oil to lubricate the filter seal
, and fill the new filter with clean
fuel.
•
Install the filter on the filter head .
•
Tighten the filter until the gasket con-
tacts the filter head surface.
•
Tighten the filter on additional 3/4 ~ 1
of a turn with the filter wrench, on as
specified by the filter manufacturer.
Note :
Mechanical over tightening of the fil-
ter can distort the thread or damage
the filter element seal.
5.5. Fuel System Checks
Fill the tank with the recommended fuel. Keeping tanks full reduces water condensation and
helps keep fuel cool, which is important to engine performance.
Make sure fuel supply valves (if used) are open.
To insure prompt starting and even running, the fuel system must be primed with the fuel feed
pump manually before starting the engine the first time, or after a fuel filter change.
Refill at the end of each day’s operation to prevent condensation from contaminating the fuel.
Condensation formed in a partially filled tank promotes the growth of microbial organisms that
can clog fuel filters and restrict fuel flow.
If the engine is equipped with a fuel water separator, drain off any water that has accumulated.
Water in fuel can seriously affect engine performance and may cause engine damage.
DAEWOO recommends installation of a fuel water separator on vehicles.
