Preventative Maintenance Procedures
1. Remove dirt and road debris from jacks (and stabilizer struts if equipped) as needed.
2. If jacks are down for extended periods, it is recommended to spray exposed leveling jack tubes with
a spray lubricant every 3 months for protection. If your coach is located in a salty environment, it is
recommended to spray the rods every month.
Your coach should be supported at both front and rear axles with jack stands before working
underneath. Failure to do so may result in death or serious injury.
