if the wheelchair itself is incorrectly used or if a problem arises due to
poor maintenance.
The information set out in this manual may be modified without prior

reserved. No part of this document may be photocopied or reproduced

Warranty Terms &
Conditions

Limitation of Liability
Limitation of Liability
This warranty does not extend to the consequential costs from fault
clearance, in particular freight and travel costs, loss of earnings,
expenses, etc.
• Natural wear and tear.
• Inappropriate or incorrect use.
• Defective assembly or setting-up by the purchaser or third parties.
• Defective or neglectful treatment.
• Use of unsuitable spares.

Intended Use
The NXT™ manual wheelchair has been designed to provide mobility and com-
fort for persons with impaired mobility.
The wheelchair has been designed to be used by a seated user with a carer/
attendant in both indoor and outdoor environments.
The wheelchair has, in its standard format, been designed to accomodate
users who weigh up to a maximum weight of 91Kg (14.4 stone) for all sizes,
have all limbs intact and have sufficent upper body strength to maintain a safe
position within the wheelchair without the addition of supporting aids.
Adaptations from the standard wheelchair format are available to
accommodate users who do not meet the above criteria but these will only be
considered after a suitable risk assessment has been carried out by the product
prescriber. For example, a user with either a full or partial amputation or other
condition, which affects the natural centre of gravity will need to have a stability
evaluation to minimise the risk of inadvertent tipping.
The wheelchair should only be used in accordance with the safety advice given
within this user guide. Failure to follow the recommended advice within this user
guide could lead to personal injury.
No claims are made that the product will medically improve the circumstances
or condition of the user.

Safety & Operating

Safety & Operating Limits
Stability and Equilibrium
To ensure that the wheelchair remains stable and is manipulated correctly,
you must always maintain good equilibrium. Many actions cause the user
of a wheelchair to reach out, lean over or move about within the wheelchair
and outside it. These actions will change your centre of gravity and weight
distribution of the wheelchair. Your wheelchair has been designed to remain
stable for normal everyday use if it is used correctly taking the precautions
recommended in this manual.
Weight Limit
The maximum user weight limit is 91Kg (14.4 stone) for all sizes and configurations.
However, the wheelchair user’s level of activity is important. For example, an
active user weighing 60Kg may subject the wheelchair to more stress than
a less active user weighing 90Kg. We recommend very active wheelchair
users to choose an appropriate design of wheelchair. Your INVACARE approved
distributor will advise you on the best model.
Reaching For An Object From A Wheelchair
The limitations on reaching out from a wheelchair shown in Figure 1 have been
produced using a representative sample of wheelchair users. Only the arms
should extend beyond the seat of the wheelchair. For safety reasons, the body
and head should remain within the wheelbase.
Position the castors to give the longest possible wheelbase (Figure 2). Lock the
manual brakes on the rear wheels.

Safety & Operating
Limits
Leaning Forwards
(Figures 3, 4, 5)
Move the wheelchair as close as possible to the object you wish to reach. Only
reach out for objects that are within arm’s length in a normal sitting position.
Leaning Backwards
(Figures 6, 7)
Move the wheelchair as close as possible to the object you wish to reach. Only
lean back for objects that are within arm’s length in a normal sitting position.

Safety & Operating
Limits
Transferring To Other Seats
Leaning To One Side
(Figure 8)
This is a dangerous manoeuvre as it is easy to tip sideways.
To move up to an object and lean over, you must use the castors as a means of
keeping the wheelchair stable and balanced.
For your safety, it is essential to be in the correct position.
Do not try to pick something up from the floor if this would upset your balance.
It is possible to move from and to a manually propelled chair if the
following guidelines are followed. INVACARE does not reccomend any particular
method for transferring: This is the responsibility of a medical advisor who should
consider your level of disablity and type of wheelchair. When transferring, either
to get out of or return to your wheelchair, make sure that the gap between the
two seats is as small as possible.
(Figures 9, 10)

Safety & Operating

When transferring, either to get out of or return to your wheelchair, make sure
that the manual brakes on the rear wheels are on to prevent the wheels moving
(Figure 11).
Turn both castors towards the seat to which you wish to move. Lift up the
footplates (Figure 12).
Do not stand on the footplates.
If possible, swing the legrest hangers out to the side to clear the passage
(Figure 13).
If possible, flip up the armrests on the side between the wheelchair and the
other seat (Figure 14).
Note: Never stand on the footplates (Figure 15).

Tilting The Wheelchair
To tilt the wheelchair (Figure 16), a second person should grip the handle
firmly. Warn the user of the wheelchair before tilting it and remind him/her
to lean backwards. Check that the user’s feet and hands are clear of all the
wheels. Push smoothly until the wheelchair is at the point of equilibrium. At this
stage, the helper will feel a difference in weight distribution. Turn the wheelchair
in the direction required and negotiate the obstacle.
Lower the front of the wheelchair smoothly, holding the handles firmly. Do not
lower the wheelchair suddenly for the last few centimeters before returning to
the normal position, this may cause discomfort.

Kerbs, Or Obstacles 30mm To 50mm High
Method 1 - Negotiating the obstacle forwards
(Figure 17)
The helper should tilt the wheelchair until the castors have passed over the
kerb. Move the wheelchair forwards and lower the castors gently onto the
pavement. Push the wheelchair until the rear wheels touch the kerb. Lift and
push until the rear wheels have mounted the kerb. Do not just lift by the handles
on the backrest.
Method 2 - Negotiating the obstacle backwards
(Figure 18)
The helper should stand on the pavement and turn the wheelchair until the
rear wheels are against the kerb. Tilt the wheelchair backwards to the point of
equilibrium and, in a continuous movement, pull the wheelchair until the rear
wheels mount the kerb and pass onto the pavement. Do not lower the castors
to the ground until you have pulled the rest of the wheelchair sufficiently far to
clear the kerb.
Note: Folding backs should always be checked to ensure they are engaged.

Steps, Stairs Or Obstacles Over 50mm High
We recommend that you take very great care when taking a wheelchair up or
down stairs. Two people are required for this.
ADVICE TO SECOND OR THIRD PERSONS:
Make sure that you get hold of fixed, non-removable parts only!
Using the following procedure for going upstairs (Figure 19): Tilt the
wheelchair to its point of equilibrium. One helper (at the back) holds the
wheelchair up against the first step, gripping the handles firmly to lift. The
second helper, holding a firmly fixed part of the front frame, lifts the wheelchair
above the stairs and holds it while the first helper places one foot on the
following step and repeats the operation. The wheelchair must not be lowered
until the last step has been negotiated and until the chair is clear of the stairs.
Escalators
Do not use an escalator when moving a wheelchair from one floor to another.
This might cause serious injury.

Upward & Downward Slopes (Operating Limits)
Do not attempt to go up or down slopes greater than 10% without assistance

Always go straight up and down slopes otherwise the wheelchair might overturn
(Figure 21).

Unfolding the NXT
For ease of transporting and lifting, the
NXT can be easily unfolded and folded.
Always engage the wheel locks by pushing
forward or pulling back on the levers or
engaging the foot lock before unfolding the
chair. (see page 27).
1. Unfolding is accomplished by applying
even downward pressure on the cross
braces. The cross braces will lock into
place.
Note: The cross braces need to be
opened to their maximum point
where the stops rest in the
notches of the cross brace and
lock into place.
2. Grasp the push handles and push them
to an upright position where they will
lock into place in the seat frame receivers.
This operation must always be done
prior to assembling the seating to the
wheelchair.
3. Push the flip back armrests down to the
flat position or insert optional T-arm or
Dual Post Armrests into receiver socket
until it snaps into place.
