5. The wheels, castors and tyres should be checked periodically for cracks and wear; and
should be replaced when necessary.

®

Stability Warning
The seat height, seat depth, back angle, seating system/upholstery, position of the rear
wheels, position of the front casters, seating options (e.g. headrest, back bag, …) as well
as the user condition directly relate to the stability of the wheelchair.
Any change to one or any combination of these factors changes the centre of gravity and
may cause the wheelchair to increase/decrease in stability.
NOTE: When changes to the left-
hand column occur, follow across
the chart and refer to the X
procedure to maintain the proper
stability, safety and handling of the
wheelchair.
