Adjusting/Replacing the Drive Lockout Sensor

Risk of Death or Serious Injury
NEVER operate the wheelchair or elevate/lower the seat while in any tilted/
reclined/back angle position over 20° relative to the vertical position. If the drive
lock-out does not stop the wheelchair from operating or the seat from elevating/
lowering in a tilt/recline/back angle position over 20° relative to vertical, DO NOT
operate the wheelchair or elevate/lower the seat.
The wheelchair user MUST have a clear line of sight to drive safely. On initial chair
delivery and after adjusting the back angle, drive lock-out switch tilt system or
recline system, tilt and recline the seat back to the farthest driving position
IMMEDIATELY before drive lock-out engages and ensure there is a clear line of
sight present in which to drive the wheelchair. If a clear line of sight is not present,
have the back angle repositioned or readjust the lockout angle such that safe driving
with a clear line of sight is achieved.
