WARNING!
Risk of tipping - do not remove support wheels
If the wheelchair is fitted with support wheels they must remain installed to
reduce the risk of the wheelchair tipping forward due to speed or prevailing
circumstances. It is important to drive the wheelchair at a safe speed to reduce
the need for sudden stops that may cause the wheelchair to tip forward.
Always be aware of the seat position and how it might affect the stability of the
wheelchair on different surfaces even with support wheels.
