Intended Use
Intended Use
The NXT™ manual wheelchair has been designed to provide mobility and comfort 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 suffi cent 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 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 confi gurations.
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.

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 fl oor 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.

Tilting The Wheelchair
To tilt the wheelchair (Figure 16), a second person should grip the handle fi rmly. 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 fi rmly. 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 suffi ciently 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 fi xed, 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 fi rst step, gripping the handles fi rmly to lift. The second helper, holding a fi rmly fi xed part of the front frame, lifts the wheelchair above the stairs and holds it while the fi rst 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.

Adjustments
Adjustable Height Flip Back Armrest
To adjust the arm height, flip the release
lever (under the front of the arm pad) to
the horizontal position. Slide the arm upward
to the desired location. Flip the release
lever back to the vertical position.
Castor Fork Adjustment
Interchanging castors can easily be done with dual hole castor forks. Currently, 3”, 5” , 6” and 7” castors are available for use. A smaller fork is used with the 3” castor only. To adjust, loosen the bolt and remove the castor. Change the castor and/or position the castor upward or downward in pre-drilled holes on the castor fork. Replace the bolt and tighten securely.
Wheel Lock Adjustment
When the rear wheel is repositioned, it is important that the wheel lock is readjusted also.
Adjustment can be made by loosening the 1/4-
20 x 1” button head screws and sliding the wheel lock assembly along the frame tubing so that the wheel lock contacts the tyre in the locked position. Continue to adjust until the knurled grip handle embeds into the tyre approximately 1/4” when in the locked position. Tighten the screw until wheel lock is snug to frame tube.

!
Wheel locks are not designed to slow the chair down when it is moving. When the chair is stopped, engaging properly adjusted wheel locks will prevent the rear wheels from turning.
31
Adjustments
Rear Axle Adjustment
The position of the rear axle is the most critical adjustment on the
NXT
wheelchair. The center of gravity and the seat height position are all determined by the axle adjustment.
Warning:
Your healthcare professional should assist you in adjusting the axle position. Position of the axle will be based on your abilities and limitations.
Center of gravity adjustment may be accomplished by moving the rear axle plate forward or backward on the frame.
Seat height and/or angle may be changed by changing the position of the axle upward or downward on the axle plate.
Warning:
Your healthcare professional should assist you in adjusting the axle position.
Position of the axle will be based on your abilities and limitations.
Warning:
The wheelchairs become less stable if forward axle positions are used. The further forward the axles are positioned, the easier it is to tip the chair over forward or backward. Moving the axle backward will increase the stability of the chair. This backward adjustment will create increased turning pressure.
Note:
A front castor adjustment should be made to correspond with any changes in rear seat height/angle.
Anti-tip Lever Adjustment
Height
1. Loosen the screw and nut on the anti-tip
2. Raise or lower anti-tip roller assembly until
at 1-1/2” to 2” off of the ground).
3. Re-install screw and nut. Tighten securely.
4. Repeat procedure on opposite anti-tip lever.

Cleaning & Storage
Cleaning
It is important for optimum performance to clean and maintain your NXT™.
We recommend that the frame fi nish be cleaned with mild soap and water.
In order to operate the NXT™ properly and safely, routine maintenance will extend the life and effi ciency of your wheelchair.
Safety Inspection Checklist
Follow these maintenance procedures for optimum performance of your NXT™ wheelchair:
1. Check to see that the wheelchair rolls straight.
2. Tyres: Check for fl at spots, wear and proper infl ation.
3. Wheel lock:
a. Check to see that the locks engage easily.
b. Check that the locks are free of wear
c. Check to see that the locks do not interfere with the tyres when rolling.
4. Ensure that all fasteners are secure.
5. Castors: Inspect axle for proper tension. Spin the castor. The castor should spin
freely and come to a gradual stop.
Storage
The NXT™ folds down to a small unit and the rear wheels may be removed. We suggest when storing the wheelchair, that it be stored in an indoor, cool and dry area.

Checking The General Condition
For maintenance operations, consult your distributor who has all the necessary information.
Ask your distributor to annually inspect your wheelchair thoroughly and carry out in depth maintenance. Regular maintenance allows defective or worn parts to be identified and improves the normal operation of your wheelchair.
The following table shows what to check when the wheelchair is delivered, each week, each month and at 6 monthly intervals.
Checks to be Made:
1. General:
The wheelchair moves in a straight line (no resistance or drag)
2. Manual brakes:
The manual brakes do not touch the tyres when moving
The manual brakes are easy to operate
The articulations are not worn and do not show signs of play
3. Frame work
Examine them to check that they are not worn or bent
4. Clothing protectors/armrest upholstery
Check that all fixings are in position and tightened

Transport
INVACARE always advises that a wheelchair secured in a vehicle will not provide the equivalent level of vehicle seating systems and recommends transfer to the vehicle seating, but also recognises that it is not always practical for the user to be transferred. In those cases where it is considered that the user must be transported whilst within the wheelchair, then the following advice should be followed.
Note: The wheelchair user safety during transportation largely depends upon the diligence of the person securing the tie downs and passenger restraints.
designed and equipped to transport a passenger seated in a wheelchair.
2. Any part of the wheelchair (accessories, etc.) that can be easily detached should be removed and stored in the vehicle luggage hold during transportation.
3. The wheelchair should always be transported in a forward facing direction. Rearward facing is only acceptable if the occupant’s head and back can be supported by a suitable bulkhead.
4. INVACARE recommends that the wheelchair be secured by 4-Point webbing tie down systems as manufactured by Unwin Safety Systems or Koller Safety Resraint Engineers.
5. When attaching tie down systems to the wheelchair it is imperative these are fi xed onto the main frame of the wheelchair and not onto any attachments or accessories (not wheels, handrims, castors, footrests, anti tipping levers etc.). Tie down points are indicated by the tie down stickers in the correct areas.
6. The tie downs should be secured, as close as possible, at an angle of 45 degrees to ensure maximum effectiveness of the restraint in all directions.
7. The occupant should be restrained independently of the wheelchair by a suitable approved passenger safety belt or harness. Pelvic restraint or lap belts supplied with the wheelchair may be used in addition to but never as a substitute for approved passenger restraints.
