Maintenance
Hydraulic System
Check 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 on the left side of the paver.
(Figure 5-19)
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 hydraulic oil.

Figure 5-19. Hydraulic Oil Cap and Sight Gauge
DO NOT loosen or remove the
hydraulic oil fill 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 fill cap and add
hydraulic oil.
(Figure 5-19)
• DO NOT use unfiltered hydraulic oil.
• Check the hydraulic oil level using the sight gauge.
• Keep the hydraulic oil filled to the correct level.
DO NOT overfill the hydraulic oil
reservoir.
Leeboy uses a lead-detection dye that
may turn the hydraulic oil a slight yellow tint.
Water Separator
Water and dirt that gets into fuel settles into the water
separator.
(Figure 5-18) As it collects, a red float rises.
When the float reaches the line on the separator, an
error code will appear on the PV480 digital display. It is
important to drain it immediately.
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 filter body and clean it with
light oil.
3. Reinsert and tighten.
