7 MAINTENANCE

7.10 Water Separator

The water separator (fig. 7.10-1),

removes water from the fuel supply
as the engine runs. Drain the water
separator daily to maintain proper
function.
To drain the water separator:
1. Shut the machine down
according to the procedure in section 5.13, then open the hood at the rear
of the machine to access the water separator.
2. Loosen the twist valve on the bottom of the separator.
3. Retighten the valve once all of the water has been drained from the catch
bowl and close the hood to complete the procedure.

7.11 Fuel Filter Change

The fuel filter 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, then open the
hood at the rear of the
machine to access the fuel filter.
