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.
