Fuel Water SeparatorFuel Water Separator
Water and dirt that gets into fuel settles into the water
separator. (Figure 5-18) An error code will appear on
the PV485 digital display when it needs to be emptied. It
is important to drain it immediately when this occurs.
If you run out of fuel, it is important
to pump the water separator to prime fuel injection
lines. Failure to do so can adversely affect
performance.
To drain the water separator:
1. Pull retainer clip from plug to disconnect the
harness.
2. Unplug the harness, then unscrew the plug.
3. Drain and reinsert components.

To clean the water separator:
1. Follow the previous steps for draining the water
separator.
2. Loosen and remove the lter body and clean it with
light oil.
3. Reinsert and tighten.
HYDRAULIC SYSTEM
Check Hydraulic OilCheck Hydraulic Oil
The hydraulic motors and hydraulic cylinders use the
same hydraulic oil tank and hydraulic oil supply.
Take care when working with the
hydraulic system to ensure it is completely clean.
Never allow the hydraulic oil level to
fall too low. Pump damage will occur.
DO NOT use your hands on any
hydraulic hoses, ttings or system component when
checking for leaks. Serious personal injury can
result from an oil leak under high pressure. Oil can
be injected under the skin by high pressure. Protect
the eyes by wearing safety glasses.
DO NOT loosen or remove the
hydraulic oil strainer ll cap when the hydraulic oil
is hot. Always loosen the cap slowly to relieve any
pressure in the hydraulic oil reservoir.

Figure 5-19. Hydraulic Oil Cap and Sight Gauge
Check the hydraulic tank oil level daily using the sight
gauge just inside the right engine access panel. (Figure
5-19) Add hydraulic oil if needed (the hydraulic oil cap is
just above the sight gauge):
• Fill to the black line on decal to the right of the sight
gauge if the hydraulic oil is cold.
• Fill to the ll line (at the C°) if the hydraulic oil is at
normal operating temperature (preferred method for
an accurate reading).
• Slowly unscrew the hydraulic oil strainer ll cap (above
sight gauge) and add hydraulic oil.
• Keep the hydraulic oil lled to the correct level.
