1. Backrest
The adjustable backrest can be folded down by means of a locking mechanism fitted to
both sides of the lower part of the backrest pillars. To fold the backrest down, push on
both of the black plastic levers, then pull back and down on the top part of the backrest.
To return to the original, reverse the procedure, making sure the mechanisms are locked
securely.
2. Handles
The handles are designed for the helper to propel the chair. They must not be used solely
for lifting the chair over obstructions or kerbs (see negotiating obstacles)
The helper must not place all of their weight on the handles by lifting their feet off the
floor as this will place adverse strain on the handles.
3. Armrest
PVC pads are fixed onto the armrest for comfort and can be replaced as spare parts.
4. Seat Upholstery
Periodically check the upholstery for signs of tears or sagging. Replace immediately if the
seat is damaged. Remember: the seat upholstery is the primary weight supporting material.
5. Footplates
The footplates are intended as a foot support only when you are sitting in the chair. On
no account should you stand on the footplates. The heel loops or calf straps (if fitted) can
be used to secure the position of the feet. The footplate assemblies can be adjusted in
height by loosening the nut of the base of the adjustment tube, positioning the plate at
the required height and tightening the nut to secure the assembly. The footplate supports
can be swung away to the outside of the chair. To carry out this procedure, pull the release
lever towards the front and swing the support to the outside of the chair. If the support is
to be removed, lift it upwards. To re-fit and return to the original position, reverse the above
procedure.
6. Castor and bearing
The front and rear wheels are solid puncture proof tyres. These should be checked at
regular intervals to monitor any wear. Chairs 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 chair 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 on the front wheels allow the chair to be steered in either left or right
direction. An adjustment locknut is located under the castor cap. If the locknut is too tight,
the chair will be difficult to steer.
7. Wheel lock assembly
These are used to hold the chair in a stationary position, and are fitted on either side of the
chair on the back wheels. They should not be used when the chair is moving or to slow it
down. They should always be applied together.
To operate, pull the brake lever back towards the back of the chair. This will immobilize the
chair. To release the brake, move the lever forwards the front of the chair.
