STABILITY WARNINGS
The seat dump, back angle, seating system, caster size and position, rear wheel size
and position, anti-tippers, as well as the user condition directly relate to the stability of
the wheelchair. Any change to one (1) or any combination of the nine (9) may cause
the wheelchair to decrease in stability. These adjustments MUST be performed by a
qualified technician ONLY.
To maintain maximum stability, position the rear wheels in the most rearward position in
the axle mounting plate. Moving the rear wheels to any of the other mounting positions
causes the wheelchair to decrease in stability.
ALWAYS ensure stability BEFORE moving the rear wheels forward. TEST wheelchair BE-
FORE it is occupied by the end user to ensure safety.
