6. Castor and bearing
The front wheels have solid puncture proof tyres. These should be checked at
regular intervals to monitor any wear. Wheelchairs become difficult to steer
and propel when surfaces have worn flat. It is recommended that both front
tyres are replaced at the same time to avoid one side of the wheelchair from
being higher than the other.
The wheel is secured to the castor fork by an axle bolt and axle nut.
Periodically, this bolt and nut should be checked and tightened if necessary to
allow a snug but free spinning fit. The castor fork swivel allows the wheelchair
to be steered. An adjustment locknut is located under the castor cap. If the
locknut is too tight, the wheelchair will be difficult to steer.
7. Wheel lock assembly
These are used to hold the wheelchair in a stationary position, and are fitted
on either side of the wheelchair. They should not be used when the
wheelchair is moving or to slow it down. They should always be applied
together.
To operate, push the brake lever forward towards the front of the wheelchair.
This will immobilize the wheelchair. To release the brake, move the lever
towards the rear of the wheelchair.
8. Cross Bar
Operation of the cross brace permits the wheelchair to be opened and closed
easily. It should be inspected at regular intervals for signs of wear and
bending.
9. Folding Backrest Device
Push down the hinge to fold down the backrest. Automatically lock when pull
up the backrest handle. This device is to enhance the storage feature.
