The Lippert Electric Stabilizer Jack is a 12VDC electric motor-driven system designed to stabilize a coach. It operates as a negative ground system, utilizing the chassis frame as a ground and requiring an independent ground wire back to the battery. The system's electric motor drives an acme threaded screw to extend and retract the stabilizer legs, providing stability to the coach. It is crucial to understand that this system is intended solely for stabilization and should not be used for leveling the coach or for providing service under the coach, such as changing tires or performing repairs. Misuse can lead to serious personal injury, death, and damage to the coach, and will void the Limited Warranty.

Function Description

The primary function of the Lippert Electric Stabilizer Jack is to stabilize the coach. When activated, the electric motor extends or retracts the stabilizer legs, which have footpads that make contact with the ground. This action helps to prevent unwanted movement of the coach when it is parked. The system is designed to operate with a 12VDC power supply, and its components are engineered for reliable performance within its intended scope.

Usage Features

Operating the Electric Stabilizer Jack involves a straightforward process of extending and retracting the stabilizer legs. Before operation, it is essential to ensure the coach is parked on solid, level ground and that all stabilizer jack landing locations are clear of debris, obstructions, and depressions. If parking on extremely soft surfaces, load distribution pads should be utilized under each jack to prevent sinking. It is also critical to ensure that people and pets are clear of the coach during operation to prevent injury.

To extend the stabilizer jack:

Verify that the battery is fully charged and properly connected to the electrical system.
Press and hold the "EXTEND" button on the control switch. The stabilizer jack footpads will extend until they make contact with the ground and the coach is stabilized.
Release the switch once the desired stabilization is achieved. It is important not to extend the jack for more than 1-2 seconds beyond initial ground contact, as this can put undue stress on the system.

To retract the stabilizer jack:

Again, verify that the battery is fully charged and connected.
Press and hold the "RETRACT" button on the control switch until the stabilizer jack is fully retracted.
Release the switch. The stabilizer jack must be fully retracted before moving the coach.

The system incorporates a 6 Amp in-line automatic reset circuit breaker. If the system shuts off during stabilization, it indicates that the circuit breaker has tripped, likely due to the jack attempting to support too much weight or being used for leveling. The breaker will reset within 10 seconds. If this occurs, the Electric Stabilizer Jack should be retracted until the footpads no longer contact the ground, and the process should be restarted. If the ground is significantly unlevel, the coach may need to be repositioned to allow the stabilizer jack to function correctly.

A manual override system is provided for situations where electrical operation is not possible. This system is located on the end of the jack opposite the electric motor. To use the manual override:

Crucially, disconnect one of the wire leads from the motor before manually operating the system. Failure to do so can cause electricity to backfeed through the motor, leading to serious damage and voiding the Limited Warranty.
Insert the ½” diameter crank handle over the coupler and pin at the end of the stabilizer jack. The slot in the crank handle is designed to accommodate the pin on the coupler.
Rotate the crank handle clockwise to extend the stabilizer jack or counterclockwise to retract it. It is important to note that the gears can be stripped if the stabilizer jack is manually retracted or extended to its fullest extent and the operator continues to rotate the manual override. Any damage resulting from the misuse of the manual override feature will void the Limited Warranty.

Maintenance Features

Proper maintenance is essential for the long-term dependability and performance of the Lippert Electric Stabilizer Jack. Both mechanical and electrical aspects require attention.

Mechanical Maintenance: For coaches operated in harsh environments, such as those exposed to road salt or ice buildup, it is recommended to keep the moving parts of the stabilizer jack clean. These parts can be washed with mild soap and water. No grease or lubrication is necessary for the moving parts; in fact, lubrication in some situations may be detrimental to the environment and the system's long-term dependability.

Electrical Maintenance: Optimal performance of the system relies on full battery current and voltage. Therefore, the coach's battery must be maintained at full capacity. Beyond good battery maintenance, regular checks of the electrical connections are necessary. Inspect the terminals and other connections at the battery, the control switch, and the electric motor for any signs of corrosion or loose/damaged terminals. The motor leads under the trailer chassis are particularly susceptible to damage from road debris, so ensure they are in good condition. As the system operates as a negative ground system, good wire-to-chassis contact is vital for all electrical components. The majority of electrical problems often stem from poor ground connections.

The electric motor itself contains no serviceable parts and must be replaced if it fails. Disassembly of the motor will void the warranty. However, mechanical portions of the Lippert Electric Stabilizer Jack are replaceable, and replacement parts can be obtained by contacting Lippert Components, Inc.

Safety Precautions

Several warnings and cautions are provided throughout the manual to ensure safe operation and maintenance:

Never work underneath the coach unless it is supported at both the front and rear with jack stands. Failure to do so can result in death or serious injury.
Always ensure the stabilizer jack area is clear of people and objects before and during operation. Moving parts can pinch, crush, or cut, leading to personal injury.
Do not use the stabilizer jack for any purpose other than stabilization. It is not designed for leveling the coach or for providing service access underneath.
Disconnect the battery from the system prior to manually operating the system to prevent backfeeding electricity through the motor.
Never lift the coach completely off the ground to the point where the wheels are not touching, as this creates an unstable and unsafe condition.

Adhering to these guidelines will ensure the safe and effective use of the Lippert Electric Stabilizer Jack, contributing to a stable and secure experience with the coach.
