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 right side of the radia-
tor shroud. Drain the water separator
as required (operator interface will
display water in fuel fault message)
to maintain proper function.
To drain the water separator:
1. Shut the machine down
according to the procedure in section 5.13.
2. Open the hood and right side panel to access the water separator.
3. Loosen the twist valve on the bottom of the separator.
4. Retighten the valve once all of the water has been drained from the system
and close the hood and side panel 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 5.13, allow
the machine to cool before performing
this procedure.
2. Open the hood and right side panel at the rear of the machine to access
the fuel filters.
3. Clean the outside of the filters (items 2, 3) thoroughly (fig. 7.10-1, 7.11-1).
4. Twist the housings CCW when viewed from the bottom to separate the fuel
filters 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 each assembly
(with new filter) into the machine.
