Operation
1. Make sure the 5th Wheel is parked on solid, level ground.
2. Clear all jack landing locations of debris and obstructions. Locations should also be free of depressions.
3. When parking the 5th Wheel on extremely soft surfaces, utilize load distribution pads under each jack.
4. Make sure people, pets and objects are clear of the 5th Wheel while operating the system.
Basic Jack Operation
Landing gear (front jacks) can be operated any time the system is on. Pressing the FRONT button (Fig.1G),
extends both front jacks. Pressing either the FRONT and LEFT (Fig. 1H) or FRONT and RIGHT (Fig. 1I)
buttons, the individual front jacks can be extended. If the touchpad 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 or individually by pressing LEFT or RIGHT buttons while simultaneously
pressing the FRONT button.
Middle jacks, if equipped, cannot be extended or retracted in standard mode or manual mode. Middle jacks
can only be operated in the special jack error code 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 touchpad is in the manual mode. Once the system isin
manual mode, pressing the REAR button (Fig. 1J) will extend both rear jacks at the same time.
1. To extend individual rear jacks, press the LEFT (Fig. 1H) or RIGHT (Fig. 1I) buttons while simultaneously
pressing the REAR button, depending on which jack needs to be operated.
2. If the touchpad is put into 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
or individually by pressing either the LEFT or RIGHT button, while simultaneously pressing the
REAR button.
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 5th Wheel.
Unhitching From A Tow Vehicle
NOTE: Prior to unhitching from the tow vehicle, make sure the 5th Wheel is parked on a level surface and
the tires are chocked.
1. Extend the inner legs of both landing gear (front jacks) to within 4"-5" of the ground by pulling on the
quick-release (pull) pins (Fig. 2).
2. Push the Power button (Fig. 1K). The LCD Screen will light up and display “READY Jacks: Up” (Fig. 3A).
3. Push the Up Arrow button (Fig. 1A) to scroll to “Drop Front Jacks” option on the LCD screen.
4. Red indicator lights (Fig. 3B) may come on, indicating the current disposition of the 5th Wheel. In this
case, the front and right sides of the 5th Wheel are low.
5. Push the ENTER button (Fig. 1C). Both front jacks will go to ground and stop.
6. Push the FRONT button (Fig. 1G) extending the front jacks to a sufficient height, to raise the front of
the 5th Wheel off of the tow vehicle’s hitch plate.
7. Disconnect all electrical and mechanical connections between the tow vehicle and the 5th Wheel.
8. Pull tow vehicle away and park at a safe distance.
Never lift the 5th Wheel completely off the ground. Lifting the 5th Wheel so the wheels are not touching
the ground will create an unstable and unsafe condition.

the 5th Wheel until the leveling process has been completed. Failure to remain still during the
leveling cycle could have a negative effect on the performance of the leveling system.
NOTE: For the hitch recognition feature to function, the auto level sequence must be started with the front
of the 5th Wheel above level.
Auto Level Sequence
1. When auto level sequencing begins, the front of the 5th Wheel will lower slightly to a point
belowlevel.
2. Rear jacks will be grounded.
3. A side-to-side leveling sequence occurs.
NOTE: On the 6-Point system, the two middle jacks are grounded to stabilize the 5th Wheel.
The two middle jacks do not level the 5th Wheel.
4. Each jack will perform a final grounding touch.
5. LCD display will read "AUTO LEVEL SUCCESS" (Fig. 4).
6. LCD display will then read “READY Jacks: Down” (Fig. 5A), and the green LED at the center of the four
jack buttons will be illuminated (Fig. 5B).
