• Slowly unscrew the three wing nuts to remove the
hydraulic oil strainer ll cap and add hydraulic oil,
replacing the wing nuts after lling the tank. (Figure
5-21)
• DO NOT use unltered hydraulic oil.
• Check the hydraulic oil level using the sight gauge.
(Figure 5-20)
• Keep the hydraulic oil lled to the correct level.
DO NOT overll the hydraulic oil
reservoir.
Leeboy uses a lead-detection dye that
may turn the hydraulic oil a slight yellow tint.
Change Hydraulic Oil and Filter
Changing the hydraulic oil removes the accumulation
of dirt, water and mechanical wear particles from the
hydraulic oil system. Clean, ltered oil is critical to
optimize hydraulic system operation. The hydraulic oil
system holds approximately 41 gallons.
Contaminated hydraulic oil can
shorten the expected service life of components in
the hydraulic system.
DO NOT drain the hydraulic oil when it
is hot. Hot hydraulic oil can cause serious personal
injury.
Protect your eyes by wearing
safety glasses when working on hydraulic system
components.
Use the following procedures to change the hydraulic
oil:
1. Stop the engine.
2. Allow the hydraulic oil to cool until it is at a warm
temperature.
3. Slowly remove the hydraulic oil strainer ll cap. Do
not remove the strainer portion under the cap.
4. Place a clean, lint-free cloth over the reservoir ll
tube opening and secure in place with tape.
5. Place a container sufcient to hold the hydraulic oil
as it drains from the drain hose by the access panel
on the right side of machine (close enough for the
drain hose to reach).
6. Carefully remove the plugs from the hydraulic drain
hose and open the valve over the container.
7. Allow all the hydraulic oil to drain from the hydraulic
tank into the container.
8. Reinstall the hydraulic oil drain plug on the drain
hose and tighten securely. Close valve.
9. Change the hydraulic oil lter by turning lter
counterclockwise, then replace with new lter
turning clockwise until snug (by hand only). (Figure
