Fuel Water SeparatorFuel Water Separator
Water and dirt that gets into fuel settles into the water
separator. (Figure 5-13) An error code will appear on
the PV480 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.

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 reservoir 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.
Check the hydraulic reservoir oil level daily using the
sight gauge centered on the frame in front of the control
panel. (Figure 5-14)
Check the hydraulic oil level when the hydraulic oil is at
normal operating temperature for an accurate reading.
If the hydraulic oil level falls below the bottom line (red
or black in color), add more. The hydraulic oil cap is
accessible on top of the paver hood.

DO NOT loosen or remove the
hydraulic oil ll cap when the hydraulic oil is hot.
Always loosen the cap slowly to relieve any pressure
in the hydraulic oil reservoir.
• Slowly unscrew the hydraulic oil ll cap and add
hydraulic oil.
• DO NOT use unltered hydraulic oil.
• Check the hydraulic oil level using the sight gauge.
• Keep the hydraulic oil lled to the correct level.
DO NOT overll the hydraulic oil tank.
Leeboy uses a leak-detection dye that
may turn the hydraulic oil a slight yellow tint.
