REMOVING and REFITTING BACKREST (Positive Locking models)
With the wheelchair vacated:-
1.[
Remove both Lock-Pins] 2. [Release Positive Lock Catch] 3. [Lift Backrest clear of
wheelchair]
On Standard models, operations 1 and 3 only will be required.
Refitting will be the reverse of the above, ensuring that the Positive Locking
Stem fully engages into the Catch and the Upper Support Pins engage
correctly into their Upper Mounting Brackets.
Refit both Lock-Pins.
When refitting the Standard Backrest, ensure the Upper Support Pins
engage correctly into their Upper Mounting Brackets at the same time as
the tongue locates correctly into the Seat Panel.
Refit both Lock-Pins.
BACKREST ANGLE ADJUSTMENT 5mm Hex. Key
The Backrest angle in relation to the Seat Base, is adjustable from +5˚ to
–15˚, however, this amount of adjustment may vary slightly dependant on
the position of the Seat Base on the wheelchair
seat rails. Where necessary, this may also require
adjustment via the Lock and Latch positions if the
Backrest angle has not been achievable with the
Seat in its initially fitted position.
To change the Backrest angle, slacken the two
angle locking screws Fig.14, on each side,
located through slots in the Backrest Support
Brackets. Reposition the Backrest Panel as
required and retighten all screws sufficient to prevent any movement.
NOTE: In some cases, the installer may find it necessary to re-attach the
Upper Backrest Lock-Pin Brackets in reversed positions. This will require
changing the Brackets from side to side and re-attaching to the Backrest Support
Brackets. This will have the effect of supporting the Backrest further forwards or
further backwards from its previous position.

BACKREST HEIGHT ADJUSTMENT 4mm Hex. Key
To enable the Backrest
height to be adjusted, a
Height Adjustment Panel
is attached to the upper
front face of the Backrest
Panel by two screws
inserted through the rear
of the Panel, screwing into
threaded key washers
Figs. 3, 5 and 15.
Detach and remove Upper
Backrest Upholstery.
Slacken both screws and re-position Height Adjustment panel as required.
Retighten screws just sufficient to prevent any movement.
Reattach Upper Backrest Upholstery level with the top
of the Backrest.
Where the Backrest has been raised, it may be
necessary to install the additional infill panel, between
the main Upholstery and Sacral Pad Fig.16
(Infill panel supplied and packaged with the new
caddy Seat Unit).
PELVIC SUPPORTS
4mm Hex. Key
These are adjustable individually, laterally
by 35mm each also forwards or rearwards.
Access to their mounting screws is from the
underside of the Seat Unit, Figs.2 and 4. on
removable seat units and from the upper
face of fixed seat bases.
Slacken both screws on each Pelvic
Support Bracket, reposition as required
and retighten screws sufficient to prevent
any movement.
Whilst the caddy will be supplied with the Pelvic Supports set to the pelvic
width as stated on the initial prescription form, these may still require slight
adjustment at final hand-over, due to changes in growth or seasonal clothing.
NOTE: Two alternative mounting brackets are available from RMS sales
where the required pelvic width cannot be achieved with the current
brackets. Where alternative or replacement brackets are required, please
refer to page 19.
