Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.
Note: Refer to Testing and Adjusting Manual, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Ensure that the engine is stopped before any servicing or repair is performed.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Replace the secondary fuel filter elements whenever the following conditions occur:
The differential pressure gauge registers 103 kPa (15 psi).
The fuel filters have been used for 1200 service hours.

Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Remove the old filter.
Apply clean diesel fuel to the new fuel filter gasket.
Do not fill the fuel filters with fuel before installing the fuel filters. The fuel will not be filtered and could be contaminated. Contaminated fuel will cause accelerated wear to fuel system parts.
Spin the new fuel filter into the fuel filter base until the gasket contacts the base. Tighten the fuel filter by hand by one full turn. Do not overtighten the fuel filter. Use the rotation index marks that are on the fuel filter as a guide for proper tightening. Note: Your product may have an additional secondary filter. Follow the above procedure to change the additional secondary filter.
