ƽ WARNING
Many activities require the wheelchair user to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to the normal balance,
center of gravity, and weight distribution of the wheelchair. To determine and
establish your particular safety limits, practice bending, reaching and transferring
activities in several combinations in the presence of a qualified healthcare
professional BEFORE attempting active use of the wheelchair.
The Pronto M91 wheelchairs have the following weight limitations:
To assure stability and proper operation of your wheelchair, you must at all times
maintain proper balance. Your wheelchair has been designed to remain upright and
stable during normal daily activities as long as you do not move beyond the center of
gravity. DO NOT lean forward out of the wheelchair any further than the length of the
armrests.
Coping With Everyday Obstacles
NOTE: For this procedure, refer to
FIGURE 3.1.
Coping with the irritation of everyday
obstacles can be alleviated somewhat by
learning how to manage your wheelchair.
Keep in mind your center of gravity to
maintain stability and balance.

While the walking beam allows to traverse up to a 3‐inch bump or threshold, stopping
after the wheels cross the bump poses a problem. The wheelchair cannot reverse over the
bump at this point. Continue forward and then turn around.
While the M91 is designed for use primarily in and around the home, the provider should
determine whether this wheelchair is suitable for the actual environment the wheelchair
will be used in.
DO NOT go down ramp at full speed. Some seat/back positions will cause wheelchair to
feel unstable.
CAUTION
Be aware of condition of ramp. Traction will be diminished/nonexistent on a slip-
pery surface. Proceed with caution.
