9. If a block is placed under a jack, only one jack should be blocked at any one time. Do
not block more than one jack at a time. If blocking the jack pad of one of the rear jacks
is necessary and the coach is on a slope, the opposite set of rear tires must be first
blocked to prevent rolling. If anyone is going to change a tire or go under the motor
home, the chassis frame must first be supported with appropriately rated jack stands.
10. If the control console (computer) is to be removed or replaced, all 12V power to the console should be disconnected. The
console power switch also should be in the "OFF" position.
Connecting and disconnecting the console while the 12v power
source is connected ("hot socketing") will very likely cause
damage to the microprocessor and other sensitive electrical
components in your control box.
