A Note About Drive Lock-Out
ƽ WARNING
NEVER operate the wheelchair or elevate/lower the seat while the back is 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 the
vertical position, DO NOT operate the wheelchair or elevate/lower the seat. DO
NOT attempt to adjust the drive lock-out. Have the wheelchair serviced by a
qualified technician.
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. Otherwise injury or damage may occur.
ƽ TILT WARNING or ƽ SPM Inhibited displays on the joystick or display unit when
the drive lock-out feature has been activated.
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.
*NOTE: 20° back angle can be any combination of recline, tilt, back angle and/or surface angle.
NOTE: Refer to Typical Product Parameters
on page 9 for tilt and recline angle ranges.
