- A high-pressure washer is not to be used to clean any of the leveling system components.
- Grease all jacks as shown:
- Landing Gear Jacks – Apply one or two pumps of grease to each grease zerk.
- Rear Leveling Jacks – With the jack extended halfway remove the plastic plug and apply a small amount of grease on the screw. Reinstall the plastic plug.
- Stabilizer Jacks (if equipped) – With the jacks extended so that they are about an inch from the ground apply some grease on the screw between the motor coupler and the trunnion nut.
- All jack mounting bolts and nuts for tightness. (Tighten as needed)
