9:1 OPERATING CONDITIONS
Weight distribution is the decisive factor when it comes to operat-
ing conditions. It is in part dependant upon the user's weight, size
and seating position in the wheelchair, and in part upon the position
of the rear wheels. The more weight that is placed above the rear
wheels, the easier the wheelchair is to manoeuvre. If more weight is
placed over the castors, the chair becomes heavier to drive. Sting is
delivered with a standard
3° camber. This means that the wheels are a little closer to the seat
and backrest at the top and are wider apart near the floor.
The advantages of this are that the wheelchair :
- turns more easily
- holds a steady course
- has a broader support base
allows the user to hold his/her arms closer to the body when moving
forwards- thus giving more strength to each push.
Assistant: If the user is left alone in the wheelchair, ensure that
swung
Parking: Increase the overall support base of the wheelchair
by reversing for about 10cm , thereby ensuring that
the castors swing forwards.

User alone, driving up forwards:
This method is recommended only for experienced wheelchair users.
- Ensure that the anti-tips are turned upwards.
- Drive forward to the edge of the kerb/threshold.
- Balance the wheelchair on its rear wheels so that the castors
lift off the ground high enough to clear the obstacle.
Push forwards firmly on the handrims while at the same time
leaning forward with your upper body.
Be sure to turn the anti-tip back to the down position.
