ƽ WARNINGS
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.
POWERED SEATING SYSTEMS ONLY - This seating system has been custom
designed and will be assembled to the wheelchair base before delivery to the user.
The information contained in this manual is for maintaining and adjusting the
seating system. There are very few adjustments that can safely be made by the user.
If there is a procedure or adjustment that needs to be performed on the seating
system that is not in this manual, do not perform that procedure. Have the seating
system serviced by a qualified technician.
The drive behavior initially experienced by the user may be different from other
chairs previously used. This Power Wheelchair has Invacare’s SureStep technology,
a feature that provides the wheelchair with optimum traction and stability when
driving forward over transitions and thresholds of up to 3-inches. The following
warnings apply specifically to the SureStep Feature.
• DO NOT use on inclines greater than 9°.
• DO NOT use on inclines with wet, slippery, icy or oily surfaces. This may include
certain painted or otherwise treated wood surfaces.
• DO NOT traverse down ramps at high speed. Doing so will reduce traction and
increase stopping distance.
• The end user’s weight can materially affect traction on sloped surfaces. Great
care should be taken when traversing such slopes.
To determine and establish your particular safety limits, practice use of this product
on various sloping surfaces in the presence of a qualified healthcare provider before
attempting active use of this wheelchair. Other general warnings listed within this
document also apply.
Wheelchairs should be examined during maintenance for signs of corrosion (water
exposure, incontinence, etc.). Electrical components damaged by corrosion should
be replaced IMMEDIATELY.
Wheelchairs that are used by incontinent users and/or are frequently exposed to
water may require replacement of electrical components more frequently.
