DESCRIPTION
Driving is not possible since the platform is
elevated and the chassis is not level.
The vehicle has reached the maximum
height and further lift up motion is not pos-
sible. Applicable to 2630ES or 3246ES.
While stowed, drive speed is reduced since
the control system detected that the pot-
hole protection mechanism failed to retract.
After 2 hours without activity, the control
system enters a low-power state to preserve
battery charge.

CHECK
• Check that the machine is tilted. If so, lower the platform and reposition
the machine to a level surface.
• Fully stow the platform.

control box is secured to the machine.
• Check that the pothole protection switches are securely mounted.
• Check that the elevation angle sensor is securely mounted.

tion (20' for 2630 or 26' for the 3246).
• Check that the elevation angle sensor is securely mounted.
• If there are any elevation sensor faults (DTC 251, 252, 2511, or 2512),
troubleshoot those first.
