Prior to Operation The leveling system should only be operated under the following conditions: 1. The unit is parked on a reasonably level surface. 2. Be sure all persons, pets, and property are clear of the coach while the leveling system is in operation. 3. Make sure battery(ies) are fully charged and test at 12+VDC under load.

Operation Basic Jack Operation Landing gear jacks can be operated any time the system is “ON”. By pushing the “FRONT” button (Fig. 1G), both front or landing gear jacks can be extended. By pushing either the "FRONT" and “LEFT” (Fig. 1H) or "FRONT" and “RIGHT” (Fig. 1I) buttons, the individual front jacks can be extended. If the touch pad is put in the retract mode, indicated by the orange illuminated LED next to the “RETRACT” button (Fig.
Auto Level 1. After unhitching from tow vehicle and parking the vehicle at a safe distance away from the unit, press the “ON/OFF” button (Fig. 1K) and then press “AUTO LEVEL” (Fig. 1F). NOTE: Once the automatic leveling cycle has been started, it is important that there is no movement in the coach until the unit has completed the leveling process. Failure to remain still during the leveling cycle could have an effect on the performance of the leveling system.
Homing Jacks 1. 2. 3. 4. 5. Introduce an error - disconnect one of the hall effect sensor wires at the controller. Attempt to operate the jack that is associated with the sensor wire that was disconnected. The touch pad screen will display an error for that jack. Reconnect the hall effect sensor wire. Manually extend all jacks down a minimum of 6 inches. Press and hold the retract button until all of the jacks begin to retract. The jacks will retract until they reach the hard current limit.
Manual Override - Top of Jack Motor NOTE: Use of a 12V-18V cordless screw gun or pneumatic screw gun is acceptable to manually override the jacks. Do not use an impact screw gun to perform the override procedure, as this may damage the motor. If manual override is necessary on any jack in the system, there are two options. The following process will describe how to use the top override. See next page for the bottom override. Tools needed: 3⁄8” drive ratchet and extension (no socket). 1. 2.
Manual Override - Bottom of Jack Motor NOTE: Use of a 12V-18V cordless screw gun or pneumatic screw gun is acceptable to manually override the jacks. Do not use an impact screw gun to perform the override procedure, as this may damage the motor. If manual override is necessary on any jack in the system, there are two options. The following process will describe how to use the bottom override. See previous page for the top override. Tools needed: 3⁄8” drive ratchet and extension, 5⁄16” socket. 1. 2.
Preventive Maintenance 1. 2. Remove dirt and road debris from jacks and stabilizer struts (if equipped) as needed. If jacks are down for extended periods, it is recommended to spray exposed leveling jack tubes with a spray lubricant every 3 months for protection. If the coach is located in a salty environment, it is recommended to spray the rods every month. Ensure the coach is supported at both the front and rear with jack stands before performing any troubleshooting or service to the unit.

Component Replacement NOTE: After replacing any of these components, you will need to "home" the jacks. See the corresponding sections for instructions. Landing Gear Replacement 1. 2. 3. Remove existing landing gear from the unit by removing the carriage bolts and nuts in the brackets that are holding the landing gear in place.
Rear Jack Replacement 1. 2. 3. Unbolt the jack from mounting bracket. Bolt the new rear jack (Fig. 18C) to the mounting bracket (Fig. 18B) using six bolts (Fig. 18D) and nuts (Fig. 18A) per jack. Tighten the bolts to 90 lb.-ft. of torque. Connect the wire harnesses to the rear jack motor wires. NOTE: LCI recommends zip-tying the harnesses tight against the rear jack motors to prevent damage to the harnesses. Fig. 18 Main Frame Rail B A C D Rear Sensor Replacement 1. 2.
3. Disconnect the rear sensor harness from the connector on the rear sensor (Fig. 19A). Fig. 19 A 4. Remove the screws (Fig. 20A), mounting plate (Fig. 20B) and sensor (Fig. 20C) assembly from the crossmember (Fig. 20D). Fig. 20 D C B A Rev: 01.30.2015 Page 13 Ground Control 3.
5. Remove the screws (Fig. 21A) from the rear sensor (Fig. 21B) and mounting plate (Fig. 21C) and remove the sensor from the plate. Fig. 21 B C A 6. Dry fit the mounting plate (Fig. 22A) and the replacement rear sensor (Fig. 22B) to the crossmember (Fig. 22C). The pre-drilled holes in the plate are for mounting the rear sensor to the plate. Mark on the plate where the rear sensor will set. Space between the sensor and the crossmember MUST be left so the wire harness will not be pinched. Fig.
7. Attach the replacement rear sensor (Fig. 23B) to the mounting plate (Fig. 23C) using two 3⁄8" hex head self tapping screws (Fig. 23A). Orientation is imperative for the correct operation of the leveling system. Fig. 23 B C A 8. Attach the mounting plate (Fig. 24B) and replacement sensor (Fig. 24C) assembly to the crossmember (Fig. 24D) using two 3⁄8" hex head self tapping screws (Fig. 24A). Ensure that the plate is centered side to side on the frame and that the sensor is oriented properly (Fig.
9. Connect the rear sensor harness to the connector on the rear sensor (Fig. 25A) and run the harness through the frame and up to the compartment where the controller will be mounted. Fig. 25 A Rev: 01.30.2015 Page 16 Ground Control 3.
Controller Replacement 1. 2. 3. 4. Disconnect all jack harnesses from the connectors on the controller. Remove the power and ground harness from the controller. Remove the controller (Fig. 26A) from the ceiling of the compartment. Using four #8 x 1” wood screws (Fig. 26B), attach the replacement controller (Fig. 26A) to the ceiling of the compartment, in the same position as the removed controller.
Touch Pad Replacement 1. 2. 3. Remove the face plate of the touch pad (Fig. 28A) from the mounting bezel (Fig. 28B). Unplug the harness from the connector on the back of the face plate. Plug the touch pad harness into the connector on the back of the replacement touch pad face plate and snap the face plate into the bezel. Fig. 28 B A Jack Motor Replacement 1. 2. 3. 4. Using a ½" socket or wrench, remove the two motor retention bolts from the jack (Fig. 29).
