1-Safety and operating limits
Stability and equilibrium
To ensure that the wheelchair remains stable and is manipulated correctly,
you must always maintain good equilibrium. Many actions cause the user of
a wheelchair to reach out, lean over or move about within the wheelchair and
outside it. These actions will change your centre of gravity and weight
distribution of the wheelchair.
Your wheelchair has been designed to remain stable for normal everyday use
if it is used correctly taking the precautions recommended in this manual.
1.1 - Weight limit
The maximum user weight limit is 160kgs (25 Stone) for 20" to 24" wide
chairs.
127kgs (20 Stone) for up to 18" wide chairs.
This weight includes accessories such as a compact oxygen cylinder or other
equipment required by the user.
However, the wheelchair user's degree of activity is important. For example,
an active user weighing 75 kg may subject the wheelchair to more stress than
a user weighing 115 kg. We recommend very active wheelchair users to
choose an appropriate design of wheelchair. Your INVACARE approved
distributor will advise you on the best model.
1.2 - Reaching for an object from a wheelchair
The limitations on reaching out

from a wheelchair shown in figure

For safety reasons, the body and
head should remain within the
wheelbase.
