Before performing any maintenance, adjustment or service verify that On/Off switch on
the joystick is in the Off position.
ALWAYS wear your seat positioning strap. The seat positioning strap is a positioning belt
only. It is not designed for use as a safety device withstanding high stress loads such as
auto or aircraft safety belts. If signs of wear appear, belt must be replaced immediately.
With regards to seat/chest positioning straps ‐ it is the obligation of the DME dealer,
therapists and other healthcare professionals to determine if a seat/chest positioning strap
is required to ensure the safe operation of this equipment by the user. Serious injury can
occur in the event of a fall from a wheelchair.
Avoid storing or using the wheelchair near open flame or combustible products. Serious
injury or damage to property may result.
A Note About Drive Lock-Out
NEVER operate the wheelchair while the back is in any reclined/back angle position over
20° relative to the vertical position. If the drive lock‐out does not stop the wheelchair from
operating in a recline/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 or drive lock‐out switch, 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.
One of the following will occur when the drive lock‐out feature has been activated:
•
ƽ
TILT WARNING displays on the joystick or display unit.
•
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 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, back angle and/or surface angle.
NOTE: Refer to Typical Product Parameters on page 7 for recline angle ranges.
