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.
