Measuring Approach and Departure Angle
To measure the approach and departure angles, run a string line from the meeting point of the tire and the ground up at
an angle to the lowest point on the front and rear of the trailer. These string lines are shown as dotted lines (Fig.3).

3. Remove the seal foam holding the jack wire harness in
place at the four chassis penetration locations (Fig.5A).

NOTE: When fully retracted, the rear and middle jacks
should be mounted to achieve a ground clearance equal
to the approach or departure angle or a minimum of 7” to
enable maximum level correction. Any additional ground
clearance added to the jack location will decrease the
amount of level correction available to the system.
Installation
Mid/Rear Jack Installation
1. Bolt the rear and middle jacks (Fig.4A) to the mounting
brackets (Fig.4B) using six bolts (Fig.4C) and nuts (Fig.4D) per
jack on both sides of the trailer.
2. Tighten the bolts to 90ft-lbs of torque.

4. Connect the jack motor wires (Fig.6A) to the jack wire
harnesses (Fig.6B) from the chassis for all four jacks.
NOTE: Lippert recommends zip-tying the wire harnesses
tight against the rear jack motors to prevent damage to
the wire harnesses.
