------ WARNING! ------

Personal injury or death may result from failure to adhere to the following procedures.

Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.

Clean up all leaked or spilled fuel. Do not smoke while working on the fuel system.

Turn the disconnect switch OFF or disconnect the battery when changing fuel filters.



NOTICE

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.


The primary filter/water separator is located behind the access door on the right side of the machine.

  3. Turn drain valve (4) counterclockwise to open. The drain valve is on the bottom of the water separator.

    Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information that pertains to containing fluid spillage.

  4. Drain the water and the sediment into a suitable container.

    Note: Dispose of used fluids according to local regulations.

  5. Close the drain valve (4).

  6. Disconnect the water sensor (5) from the harness.

    Note: Do not attempt to remove the sediment bowl from the housing. The sediment bowl is permanently attached to the housing. Attempting to remove the sediment bowl may damage the bowl.

  7. Unscrew filter housing (3) and remove primary filter (2). A filter wrench may be used to loosen the filter housing. Properly discard the used filter.

  8. Clean the mounting base (1).

  9. Lubricate the seal of the new filter (2) with clean diesel fuel.

  10. Install the new filter (2) into the housing.

  11. Tighten the filter housing approximately 1/6 of a turn. Do not use tools to tighten the filter housing to the filter base.

  12. Ensure that sensor (5) is in the correct position and connect to the wiring harness. If the sensor was removed from the bowl, install the sensor and tighten to 2.5 ± 0.5 N·m (22 ± 4 lb in).

  13. Open the fuel shutoff valve.

  14. Close the access door.
