and keep depressed the quick-release. Take the quick-release axle and
depress the button in its center. This retracts the bearings at the
opposite end of the axle. This will allow you to push the axle through
the center of the hub of the wheel. Your wheels are now ready to be
assembled to the frame of your wheelchair.
4.1.4.4.2 First ensure that the brake is in the OFF position. Take up the
assembled wheel and axle and depress the button in the center of the
axle, as above. This retracts the ball bearings that will allow you to push
the axle into the wheel bracket that is located on the lower rear frame of
the wheelchair. When you remove your thumb from the button on the
axle, the ball bearings should be visible protruding from the axle at the
back of the wheel bracket. This will secure the wheel safely in the frame.
(See Figure 4.13)
CAUTION:
● You must make sure that the axle is fully located in the wheelchair bracket
and that the ball bearings are fully open and have positively attached the
wheel in the frame.
● The rear wheel can be mounted at different positions on the frame to alter
the seat height and overall stability of the chair. Changing the wheel
position should be carried out by your approved repairer or therapist.
