Measuring Departure and Approach Angle
To measure departure and approach 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 or rear of the trailer. These string lines are shown as dotted lines (Fig. 5).

Installation
(Fig. 6 and Fig. 7). Tighten the nuts on the carriage bolts until
the bracket opening is less than 2 1/2 ” (Fig. 7A).
3. Connect the wire harnesses to the front jack motor wires and
run the harnesses to the compartment where the controller
will be mounted.
Note: LCI recommends zip-tying the harnesses tight against the
front jack motors to prevent damage to the harnesses.
