Basic Jack Operation
Operation
Unhitching From A Tow Vehicle
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. 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.
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.
1. Extend the inner legs of both landing gear to within 4-5 inches of the ground by pulling on the quick
release pins.
2. Push “ON/OFF” (Fig. 1K). LCD Screen will light up and display “READY JACKS: UP” (Fig. 2A).
3. Push the “UP” arrow (Fig. 1A) to scroll to “Drop Front Jacks” option on LCD screen.
4. 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.
5. Push “ENTER” (Fig. 1C). Both front landing gear jacks will go to ground and stop.
6. Push the “FRONT” button (Fig. 1G) extending the front landing gear to a sufficient height, which raises
the front of the trailer off of the tow vehicle’s 5th wheel hitch plate.
7. Pull tow vehicle away and park at a safe distance.
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 the 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.

Auto Level
1. After unhitching from tow vehicle and parking the tow 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
1. When Auto Level Sequence begins, the front of the trailer will lower to a point near level.
2. Rear leveling jacks will be grounded.
3. A side to side leveling sequence will occur.
NOTE: At this point on the 6-point system, the two middle jacks will be grounded to stabilize the trailer.
These two jacks do not level the trailer.
4. Each jack will perform a final grounding touch.
5. LCD will read “AUTO LEVEL SUCCESS” (Fig. 3).
6. LCD will then read “READY Jacks: Down” (Fig. 4A), and the green LED at the center of the four jack
buttons will be illuminated (Fig. 4B).

Hitch Recognition
1. Turn on the touch pad.
2. Push the “UP” arrow (Fig. 5A) to scroll to
“Auto Reconnect” option on LCD screen.
3. Push "ENTER" (Fig. 5B). All leveling jacks will
retract first, then the landing gear 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.
Fig. 5
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.
Troubleshooting
Manual Override
If manual override is necessary on any jack in the system, there are two options: a port on the top of the jack motor,
and a port on the bottom of the jack motor.
Top of Jack Motor Override:
Tools needed: ⁄” drive ratchet and extension (no socket)
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.
1. Find the port on the top of the jack motor (Fig. 6A).
2. Remove the rubber plug (Fig. 7A).
3. Insert the ⁄” drive into the port (Fig. 8).
4. Turn override until the jack extends or retracts to desired position.
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.

Preventive Maintenance
1. For optimum performance, the system requires full battery current and voltage. The battery MUST be
maintained at full capacity.
2. Check the terminals and other connections at the battery, the controller, and the jacks for corrosion,
and loose or damaged connections.
3. Remove dirt and road debris from jacks as needed.
4. 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 four to six weeks.
