A Note About Drive Lock-Out
One of the following will occur when the drive lock-out feature has been activated:
•
CMPJ+ Joysticks Only -
TILT WARNING or
SPM Inhibited displays on the joystick or display unit.
•
SPJ+ Joysticks Only - Left to right chase alternating with a steady display.
Drive lock-out is a feature designed to prevent the wheelchair from being driven after the seating system has been tilted 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.
WARNING
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.
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.
*20° back angle can be any combination of recline, tilt, back angle and/or surface angle.
Refer to Typical Product Parameters on page 11 for tilt and/or recline angle ranges.
