7.10 Water Separator
The water separator (item 1)
removes water from the fuel supply
as the engine runs. (fig. 7.10-1) It is
located on the left side of the engine
compartment. Drain the water sepa-
rator as required (operator interface
will display water in fuel fault mes-
sage) to maintain proper function.
To drain the water separator:
1. Shut the machine down
according to the procedure in section 5.12.
2. Open the hood to access the water separator.
3. Twist valve on the bottom of the separator CCW until fuel begins to flow.
4. Retighten the valve once all of the water has been drained from the system
and close the hood to complete the procedure.
7.11 Fuel Filter(s) Change
The fuel filters should be changed every 500
service hours, or as needed. A plugged fuel
filter can cause loss of engine power, rough
running, or no start.
To change the filter:
1. Shut the machine down according to
the procedure in section 5.12, allow
the machine to cool before performing
this procedure.
2. Open the hood to access the fuel filters.
3. Clean the outside of the filters (items 2-3) thoroughly (fig. 7.10-1, 7.11-1).
4. Disconnect the sensor from item 1 and the fuel hose from item 3. Then,
twist items 1-3 CCW when viewed from the bottom to separate the catch
bowl (1) from filter (2) and then filters 2-3 from their respective filter heads.
Note: Drain fluids into a suitable catch container. Dispose according to mandates.
5. Remove each filter element, then reverse step 4 to reinstall new filters into
the machine.
