Rear Wheel Adjustments
Horizontal Adjustment (centre of gravity)
With the Enigma XSSP and XSTS models we have
incorporated features that enable you to adjust the
centre of gravity.
XSSP – Horizontal adjustment is made by moving the
axle pin into different positions within the axle plate
into present slot positions. (deluxe models only).
XSTS – Horizontal adjustment is made by removing
the rear wheel brackets using an allen key and spanner.
The brackets can then be reinstalled using the predrilled
holes on frame. Always use new nylock nuts after
adjustment
For greater stability (ie. In elevating legrest/amputee
situations) the wheels should be set back in the furthest
position. This will also increase the turning pressure.
Moving the axle position forward will lighten the front
of the chair and make it easier to turn.
WARNING – if you set the wheels forward, in
certain situations there is an increased risk of the
wheelchair tipping back. Anti – tip devices
(available via dealers) should be fitted in these
situations.
Vertical Adjustment (deluxe models only)
XSSP – Adjustment is made on height by releasing and
removing the allen key bolts, nylock nuts, nylon bushes
and connecting brackets and relocating them for axle
pin relocation in the pre-drilled alternative location
holes. Often this is done for the purpose of creating a
forward or backward tilt which will affect the push and
balance of the wheelchair. If adjustment has been made
in height, the front castor angle should also be changed.
Always use new nylock nuts after adjustment.

Castor Adjustment
There are a number of castor options that can be fitted,
consult your dealer for details on any special castor
options that you may have had fitted. Inbuilt into our
castor system is an adjustment via off centre bolts
which set the angle that the castor is positioned at.
The castor pots can be reverse fitted in order to reduce
the turning circle by shortening the wheel base length.
Remember to ensure that by setting the castor pots in a
forward position you do not make the castors clash with
the footrest.
Always use new nylock nuts after adjustment.
(This feature is only available on the deluxe models)

Quick Release Wheel Mechanism
In order to make the wheelchair as light and
transportable as possible our chairs have the facility to
remove the rear wheels without the need for tools. With
one hand holding up the wheelchair frame, the other
hand should grip the centre of the wheel, push the
centre pin inwards and in the same movement pull the
wheel hub away from the frame. This should have
successfully removed the wheel. To put the wheels
back the procedure should be reversed. If the quick
release pins appear to be reluctant to go back into place,
press the pin with the palm of your hand to push it back
home. Check that the wheel is securely fastened before
use,by pulling the wheel and ensuring there is no
sideways movement.
6
Folding Back Mechanism
The backrest has an inbuilt half folding back which has
been designed so that the wheelchair will fit into small
spaces by reducing the push handle height. In order to
fold down the backrest, push in the black lever whilst
pulling the handle down. This operation should be
repeated for the other handle.
To put the backrest back into position , lift both handles
together and the folding mechanism will lock back
automatically.
Do not push down on the push handles to raise the front
wheels as this may result in damage. To raise the front
wheels use the stepper tube as described in point 11.
7
Brake Adjustment
Adjustment is made to the brakes by loosening the allen
key bolt heads and by sliding the brake unit along the
frame. The brakes will have to be adjusted if the rear
wheel position has been altered.
Please refer to the photograph for see which screws to
loosen. Do not loosen any other bolts.
