A Note About Drive Lock-Out

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 immedi-
ately 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.
The LED on the single function toggle switch will light 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 for Formula Invisible Super Low Tilt on page 23,
Formula TRE on page 24 or Formula PTO Plus on page 26 or 2G Tarsys on page 27 for tilt and/
or recline angle ranges.
