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 4-6 weeks.
Special Jack Error Codes
To clear 1 of the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
NOTE: In order to clear the special jack error code the jacks need to be "homed." In order to "home" jacks,
each jack MUST be able to 6" of minimum retract needed.
2. Extend all jacks to reach the 6" of minimum retract needed.
A. Press "FRONT" (Fig. 18G) to extend the front jacks (if required).
B. Press "REAR" (Fig. 18J) to extend the rear jacks (if required).
C. Press "LEFT" and "RIGHT" (Fig. 18H and Fig. 18I) simultaneously to extend the middle jacks (if
equipped and required).
3. 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.
4. The jacks are now “homed” and the special jack error code will be cleared.
NOTE: If the jacks do not retract, an error should display on the touch pad screen. This is typically caused by
wiring interruption.
