Procedure 3 - Tires and Inner Tubes

Tires will wear just like a car tire and the time will depend on the type of use. It is recommended that both tires are
changed once the tread fades. For pneumatic tires, there is a risk that a puncture will occur and the inner tube will need
to be replaced in order to keep the wheelchair operational.
3.1: Changing the tire
Remove the wheel from the wheelchair and release air in the
tube by pressing the small pin inside the valve, if a Presta
valve, then unscrew both the head and the securing ring at
base and press the top until air releases. Using 2 x tire levers
(supplied in the toolkit), unhook the tire completely from
the wheel rim. Remove inner tube and tire from wheel rim.
To install the tire, place one side of the new tire on the
wheel rim. Then insert the inner tube inside the tire and
align the valve with the wheel rim hole. Ensure there are
no kinks or uneven tension in the inner tube before putting
the second side of the tire back on the wheel rim using the

Procedure 4 - Camber Bar

The Camber Axle or Camber Tube control your wheel position and your center of gravity. It is very important to have this
set up for your requirements for performance and safety. Axle tube can be fi xed or adjustable. Fixed means this cannot
be adjusted and for a user who is experienced and knows their balance point. Adjustable position gives the user choice
and is ideal for less experienced users
4.1: Adjusting Axle Tube position
To adjust the axle position, remove wheels. Using a 5mm allen
key from the toolkit, release the top screw on each side of
the axle clamp as shown in Fig 21 (A). Once released but still
intact, move the axle backward for more stability and move
forward for more tip. Tighten the top screws once position has
been set, and carefully use the chair as if it were the fi rst time.
4.2: Replacing Axle tube
To replace the axle tube, remove wheels. Using a 5mm allen
key from the toolkit, release the bottom screw completely from
the axle clamp as shown in Fig 21 (B). Take note of the distance
between the axle clamp and the axle tube for set up of the
new axle tube. Slide new tube into the clamps and into the
same position as the old axle tube. The notch in the axle insert
must be at the top of the axle tube.
If the wheelchair feels slow after replacing the axle tube, rotate
the axle tube a little forwards or backwards to correct the
wheel alignment.

tire levers. Be careful not to pinch the inner tube. Once tire
and inner tube are on the wheel rim, replace securing ring
(if applicable) then infl ate tire a little. Adjust inner tube and
tire so that they fi t nicely on the wheel rim and infl ate to the
recommended tire pressure.
3.2: Changing the inner tube
Repeat the method above but do not remove tire
completely, just remove inner tube. If problems continue,
remove tire and inner tube and ensure there are no sharp
edges in the wheel rim which may be causing a puncture.
WARNING:
The position of the footrest, camber bar, as well as
the tautness of the back upholstery, are directly
related to the chair's stability.
Any change to one or any combination of the
three may cause the chair to decrease in stability.
Use EXTREME caution when using a new seating
position for the fi rst time.
