(Located beneath entrance step)
-Typical View
NOTE: Only fill the hydraulic reservoir with the
jacks in the retracted (UP) position.
Adding fluid with the jacks in any other
position will cause fluid to leak through
the breather/fill cap.
Hydraulic Fluid Recommendation
The leveling system is filled from the factory
with AW-22S synthetic hydraulic oil that has
been specially formulated for use in the leveling
system and that is compatible with Automatic
Transmission Fluid (ATF).
DO NOT USE brake fluid or hydraulic jack
oil, which can damage the seals and cause leaks.
Further Information
For replacement fluids, see the manufacturer's
recommendation in the leveling system operation
manual provided in your InfoCase.
