Operation
Be sure to park the trailer on solid, level ground. Clear all jack landing locations of debris and obstructions. Locations should also be free of depressions. When parking the trailer on extremely soft surfaces, utilize load distribution pads under each jack. People and pets should be clear of trailer while operating leveling system. Never lift the trailer completely off the ground. Lifting the trailer so the wheels are not touching the ground will create an unstable and unsafe condition.
Basic Jack Operation
Landing gear (front jacks) can be operated any time the system is "ON". By pushing the "FRONT" button (Fig. 1G), both front 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. 1D), the front jacks can be retracted together by pushing the "FRONT" button (Fig. 1G) or individually by pressing "LEFT" (Fig. 1H) or "RIGHT" (Fig. 1I) buttons, while simultaneously pressing the "FRONT" button (Fig. 1G).
Middle jacks, if equipped, can not be extended or retracted in standard mode or manual mode. Middle jacks can only be operated in the special jack code error mode. In order to operate the middle jacks press "LEFT" (Fig. 1H) and "RIGHT" (FIG. 1I) buttons simultaneously.
The rear jacks can only be extended when the touch pad is in the manual mode. Once system is in manual mode, pressing the "REAR" button (Fig. 1J) will extend both rear jacks at the same time. To extend individual rear jacks, press the "LEFT" (Fig. 1H) or "RIGHT" (Fig. 1I) buttons while simultaneously pressing the "REAR" button (Fig. 1J), depending on which jack needs to be operated. If the touch pad is put in the retract mode, indicated by the orange illuminated LED next to the "RETRACT" button (Fig. 1D), the rear jacks can be retracted together by pushing the "REAR" button (Fig. 1J) or individually by pressing either the "LEFT" (Fig. 1H) or "RIGHT" (Fig. 1I) buttons, while simultaneously pressing the "REAR" button (Fig. 1J).
Note: If the rear jacks will not operate individually using the method described above, but they operate properly when Auto Level is performed, the Twist Prevention Protection system has locked out the operation to prevent damage to the frame of the trailer.
Unhitching From A Tow Vehicle
Note: Prior to unhitching from the tow vehicle, ensure the trailer is parked on a level surface and be sure to chock the tires of the trailer.
- Extend the inner legs of both landing gear (front jacks) to within 4-5" of the ground by pulling on the quick-release pins.
- Push "ON/OFF" (Fig. 1K). LCD Screen will light up and display "READY JACKS: UP" (Fig. 2A).
- Push the "UP" arrow (Fig. 1A) to scroll to "Drop Front Jacks" option on LCD screen.
- Red indicator lights (Fig. 2B) may come on, indicating the current disposition of the trailer. In this case, the front and right sides of the trailer are low.
- Push "ENTER" (Fig. 1C). Both front jacks will go to ground and stop.
- Push the "FRONT" button (Fig. 1G) extending the front jacks to a sufficient height, which raises the front of the trailer off of the tow vehicle's 5th wheel hitch plate.
- Pull tow vehicle away and park at a safe distance.

Auto Level
- After unhitching from tow vehicle and parking the vehicle at a safe distance away from the trailer, 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 trailer until the trailer has completed the leveling process. Failure to remain still during the leveling cycle could have an effect on the performance of the leveling system.
Note: In order for hitch recognition feature to function, the auto level sequence must be started with the front of the trailer above level.
Auto Level Sequence
- When Auto Level Sequence begins, the front of the trailer will lower slightly to a point below level.
- Rear jacks will be grounded.
- A side to side leveling sequence occurs.
Note: At this point on the 6 point system, the 2 middle jacks are grounded to stabilize the trailer. These 2 jacks do not level the trailer.
- Each jack will perform a final grounding touch.
- LCD will read "AUTO LEVEL SUCCESS" (Fig. 3).
- LCD will then read "READY Jacks: Down" (Fig. 4A), and the green LED at the center of the 4 jack buttons will be illuminated (Fig. 4B).
Note: If the AUTO LEVEL sequence does not perform as described, place the system in manual mode and test that the jacks operate correctly by pushing their coordinating buttons on the touch pad; i.e. "FRONT" button operates only the front jacks, etc.

Hitch Recognition
- Turn on the touch pad.
- Push the "UP" arrow (Fig. 5A) to scroll to "Auto Reconnect" option on LCD screen.
- Push "ENTER" (Fig. 5B). The rear jacks and middle jacks (if equipped) will retract first, then the front jacks will extend to raise the trailer to the height where the auto level sequence was started.
Note: If the auto level sequence was started with the front of the trailer in a below-level condition, the Hitch Recognition will not function and the LCD will display "Feature Disabled." In order for the Hitch Recognition feature to function, the auto level sequence must be started with the front of the trailer above level.
Troubleshooting
Ensure the trailer is supported at both the front and rear with jack stands before performing any troubleshooting or service to the trailer. Failure to do so may result in death or personal injury.
Manual Override
Note: For ease of manual override it is recommended to unplug the power harness to the motor prior to performing the manual override procedure.
Note: Use of a 12-18 volt cordless screw gun or pneumatic screw gun is acceptable to manually override the jacks. Do not use an impact screw gun to perform any of the override procedures, as this may damage the motor. If manual override is necessary there are two options.
Top of Jack Motor Override:
Tools needed: 3/8" drive ratchet and extension (no socket)
- Find the port on the top of the jack motor (Fig. 6A).
- Remove the rubber plug (Fig. 7A).
- Insert the 3/8" drive into the port (Fig. 8).
- Turn override until the jack extends or retracts to desired position.
Bottom of Jack Motor Override:
Tools needed: 3/8" drive ratchet and extension, 5/16" socket
- Find the port on the bottom of the jack motor (Fig. 9A).
- Remove the rubber plug (Fig. 10A).
- Insert the 5/16" socket into the port (Fig. 11).
- Turn override until the jack extends or retracts to desired position.

System Settings
Zero Point Calibration
The "Zero Point" is the programmed point that the trailer will return to each time the Auto Level feature is used.
Note: Prior to starting this procedure, double check all connections on the controller, jacks, and touch pad.
- In manual mode, run the jacks to level the trailer. This is best achieved by placing a level in the center of the trailer and leveling it both front to back and then side to side. (See "Basic Jack Operation" for instructions on how to manually operate the system).
- Once the trailer is level, turn off the touch pad.
- With the touch pad off, press and release the "FRONT" button (Fig. 1G) 5 times and then press and release the "REAR" button (Fig. 1J) 5 times.
- The touch pad will flash and beep and the display will read "ZERO POINT CALIBRATION ENTER to set, Power to Exit" (Fig. 12).
- To set the current position as the zero point, press the "ENTER" button (Fig. 1C).
- LCD display will read "Zero point stability check" (Fig. 13).
- LCD display will read "Zero point set successfully" once process is complete (Fig. 14).
- The system will set this point as its level state and the touch pad will turn off.

Preventive Maintenance
- For optimum performance, the system requires full battery current and voltage. The battery must be maintained at full capacity.
- Check the terminals and other connections at the battery, the controller, and the jacks for corrosion, and loose or damaged connections.
- Remove dirt and road debris from jacks as needed.
- If jacks are down for extended periods, it is recommended to spray exposed leveling jack rods with a silicone lubricant every three months for protection. If the trailer is located in a salty environment, it is recommended to spray the rods every 4-6 weeks.
