SECTION 6—WHEELCHAIR OPERATION
Part No 1134839 33 Power Tiger™
A Note About Drive Lock-Out
ƽ WARNING
NEVER operate the wheelchair while the back is in any tilted/back angle position
over 20° relative to the vertical position. If the drive lock-out does not stop the
wheelchair from operating in a tilt/back angle position over 20° relative to the
vertical position, DO NOT operate the wheelchair. 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 or tilt system, tilt
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.
One of the following will occur when the drive lock-out feature has been activated:
• MPJ+ Joysticks Only - ƽ TILT WARNING or ƽ 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.
*NOTE: 20° back angle can be any combination of tilt, back angle and/or surface angle. Refer to
Typical Product Parameters on page 11 for tilt angle ranges.
