Drive Lock-Out

Drive lock-out is a feature designed to prevent the wheelchair from being driven after the
seating system has been tilted or reclined beyond 20°* relative to the vertical position. The
back can be positioned at a 10° relative offset to the seat base, thereby resulting in a back
angle potential of 30° before which the drive lock-out is activated. This may affect the
wheelchair user's line of sight while driving. Make sure the wheelchair user can see
properly to ensure safe driving. When the drive lock-out feature has been activated, the
LED on the single function toggle switch will light.
*NOTE: 20° back angle can be any combination of tilt, recline, back angle, and/or surface angle.
WARNING
NEVER operate the wheelchair while in any tilted/reclined position over 20° relative
to the vertical position. If the drive lock-out does not stop the wheelchair from
operating in a tilt/recline position 20° relative to the vertical position, DO NOT
operate the wheelchair. Adjust the potentiometers. Refer to Adjusting the Tilt
Potentiometer on page 152 or Adjusting Recline Potentiometer on page 154.
