Ground Control 3.0 Manual
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.
WARNING
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.
