Hydraulic Jack Danger

Most of us have, at one time or another, used our Power Gear hydraulic jacks to raise the coach so that we could work under it. Obviously, this is not recommended, but there are also two other dangers to be aware of if you insist on doing this:

The parking brake is only applied on the rear wheels. The front wheels will spin freely, so be sure you chock them. If you don't, only your jacks are keeping the D from rolling when the back is raised.

The jacks will automatically RETRACT if battery voltage is low. One owner left his key on to do some electrical troubleshooting, only to be nearly squished an hour later when his jacks unexpectedly retracted, due to low battery voltage.


The DISCOVERY OWNERS ASSOCIATION, INC, was formed to promote the sharing of information and the camaraderie of fellow Discovery motorhome owners. Membership in the club is limited to owners of Fleetwood Discovery motorhomes.
