CARE AND CLEANING INSTRUCTIONS
Fabrics, Vinyl's and Cloth covers
1. Minor spills can be removed with kitchen roll and the area wiped with clean water.
2. Staining should be removed as quickly as possible after contact.
3. Do not rub, rubbing will spread the stain over a larger area and may distort the
surface texture of the fabric.
4. For water based spills such as food, drink and vegetable oils, blot up the spill by
applying pressure with non-coloured paper towels, tissues or dry absorbent cloths.
Soak a small piece of cloth in a solution of mild detergent and warm water (use
cold water for blood), using a small amount of the solution at a time and with a
dabbing or blotting motion, work inwards from the edge of the stain to prevent it
spreading. Do not over wet. Excessive soaking may cause rings on the surface
spreading the stain further and may also damage the fabric or foam.
5. This step may need to be repeated and is dependent on the nature of the stain and
the amount of staining present. Continue treatment until stain is removed, always
remembering to remove excess moisture from the fabric prior to the next
treatment.
6. Rinse by applying clear tepid water using a small piece of non-coloured sponge or
clean white cloth, again working inwards from the edge of the treated area.
7. Disinfectants which do not contain organic solvents may be used according to the
manufacturer’s directions. Antibacterial spray or wipes can be used, be sure to dry
the product before use.
8. Do not soak the fabric.
9. Do not use organic solvents or dry cleaning fluids. Do not use abrasive cleaners.
10. For disinfectant purposes, a small quantity of household bleach diluted with water
(no more than 3% bleach) can be used, take care to rinse with water.

45˚pelvic strap
HOW?
Clip the buckle in the centre of the strap to secure your
child. The strap length is altered by opening the swiss
locks beneath the back the seat (fig 6) and pulling the two
straps until the right length is achieved. Always make sure
that you pull evenly from both sides, and that the buckle
stays in the middle of your child, and is covered by the
fabric pad. This helps to keep them sitting straight and
comfortable.
Ensure a fingers width between the belt and the child to
prevent over tightening or the child moving to an inappro-
priate position.
Note: Always route this strap under the hip pads
The Chest Strap/Thoracic Pads
HOW?
The chest strap length can be adjusted easily using the Swiss lock buckles (fig 7). The thoracic pad height
can be adjusted by moving the thoracic pad bar into the appropriate channel. Simply remove the screw in
fig 8, move the thoracic pad bar to the required height and re-insert the screws in the relevant holes to lock
the bars in place.
WHY?
The pelvic strap not only holds your child safely in the seat but also holds their hips in place in the back of
the seat. This gives them a stable base for sitting. The position of your child’s hips is important as it is the
base of their posture. Weight should be evenly distributed on either side and their pelvis should be level
and not rotated.
A 5mm T-bar Allen key is provided for adjusting Gamma.
Fig 6
Making & Using the Adjustments
WHY?
The strap and pads have been designed to mould around your child’s upper trunk to offer maximum
support when seated. They should fit snugly around your child’s upper body and be secure but not too
tight. If your child needs specific support in certain areas, please consult your therapist for advice.
Fig 7 Fig 8
Secure the child by using the 45° pelvic strap before you begin to make any other adjustments.
Ensure the belt is adjusted for each child and for changes of clothing.
Ensure the straps are routed under the hip pads. Ensure a finger’s width between the belt and
the child to prevent over tightening or the child moving to an inappropriate position.
POSITIONING SUGGESTIONS GIVEN IN THIS SECTION SHOULD ONLY BE TREATED AS A GUIDE. YOU
SHOULD ALWAYS CONSULT YOUR THERAPIST OR MEDICAL PRACTITIONER BEFORE USING GAMMA.

Contact Jenx Limited immediately for advice. +44 (0) 114 285 3376
NEVER LEAVE YOUR CHILD UNATTENDED WHILE USING THIS PRODUCT
Making & Using the Adjustments
The hip pads
HOW?
The width and angle of the hip pads can be adjusted by
loosening the wing nut underneath the seat (fig 10).
WHY?
The width of the hip pads should be set depending on the size of your child. The angle of these pads will
help to keep your child’s hips in a position with the correct amount of abduction or adduction.
WHY?
Set the seat depth to suit the child’s upper leg length. Ensure there is some space between the back of
the knee and the front edge of the seat so that the sitting position is comfortable. As the child grows,
adjust the seat depth accordingly.
The Seat Depth
HOW?
Loosen the two black wing nuts underneath the
seat (fig 9). Slide the seat to the required position
and re-tighten the wing nuts securely.
Secure the child by using the 45° pelvic strap before you begin to make any other adjustments.
Ensure the belt is adjusted for each child and for changes of clothing.
Ensure the straps are routed under the hip pads. Ensure a fingers width between the belt and the
child to prevent over tightening or the child moving to an inappropriate position.

NEVER LEAVE YOUR CHILD UNATTENDED WHILE USING THIS PRODUCT
The headrest
HOW?
To angle the headrest up or down and to move it forwards and backwards, loosen the wing nut shown in
(fig 12). Adjust as necessary and re-tighten.
The shape of the headrest can be altered by adjusting the 2 bars with the yellow ends; loosen the screw(s)
at the back of the pad, slide the bar(s) to the required position and re-tighten the screw(s).
If you need more height for the headrest, loosen the screw shown in (fig 13), raise the headrest to the
desired height and re-tighten the screw. If required, the headrest assembly can be removed, rotated 180°
and replaced to give greater flexibility with forwards/backwards movement (see fig 12 to 13B for alternative
position). The screw shown in (fig 13) will need to be completely removed in order to do this. Once rotated
loosen the wing nut in (fig 12) and flip the headrest pad around so that it faces forward. It can also be
removed altogether if necessary.
Making & Using the Adjustments
The Upper Back Pad
HOW?
The upper back pad can be adjusted by loosening the index
clamp (fig 11) with the Allen key. Set the height, depth and
angle as required and re-tighten the clamp.
WHY?
The upper back pad provides a firm support for your child’s
back. In conjunction with the lumbar support pad, you can
use it to manage the posture of your child and correct any
kyphosis or extension.
WHY?
The headrest should be positioned to stop the child's head from falling by giving it control from the side
and back. For children with good head control you may wish to remove the headrest altogether. If the
child’s head tends to turn to one side you may only need to use one half of the headrest and leave the
other side more open.

Ensure the straps are routed under the hip pads. Ensure a fingers width between the belt and the
child to prevent over tightening or the child moving to an inappropriate position.
Please note: do not loosen the index clamp by more than 2 full turns as this may cause the index
clamp to detach from the chair. After tightening the index clamp, move the adjustment to check
that the teeth have locked together securely. If not, tighten further.

The Lumbar Support Pad
HOW?
The lumbar support pad can be adjusted by loosening
the clamp with the Allen key as shown in (fig 14). Set the
height, depth and angle as required and re-tighten the
clamp.
WHY?
The lumbar support pad helps to support and maintain the correct position of the pelvis. By making
sure that this pad is set correctly your child’s posture can be managed more effectively.
The Footplates & Sandals
HOW?
To set the height and angle of the footplate, loosen the clamp shown in (fig 15) with the Allen key, set
the footplate to the required position and re-tighten the clamp. By loosening the wing nut underneath
the sandal as shown in (fig 16a) you can position the sandal anywhere on the surface of the footplate
and you can also rotate it to any angle.
If the footplates are not required they can be flipped up out of the way by pulling the lever (fig 16b) and
lifting the footplate upwards.
Making & Using the Adjustments
WHY?
You can set the footplate and sandals to suit your child’s specific therapeutic needs. You can create plantar
flexion/dorsi flexion, internal and external rotation and thereby correct the position of the feet.

and set the distance required. You can also flip the knee cup totally away to make transferring easier. The
angle of the knee cup arm can be adjusted by loosening the bolts shown in (fig 18), and adjusting the knee
cup arm to the required angle, and re-tightening.
WHY?
For children with a leg length discrepancy, you would set one knee cup nearer to the seat than the other.
Aim to have the knee cups supporting your child’s knees in a comfortable but secure position. The knee
cup extensions can be used on either side of the knee cup to offer adduction, abduction or to correct a
windswept posture.

Clear all items from the tray before adjustment.
Do not use hot or cold drinks on the product while using the angled tray.
The armrests & tray
HOW?
Loosening the wing nut (fig 19) allows the angle of the armrest to be adjusted. The wing nut below the
armrest (fig 20) allows the height to be altered. The grade scale on the arm rest carrier makes it easy to
get the two arm rests at the same height. This is important because the tray fixing requires both arm rests
to be at the same height.
To attach the tray, ensure the black tabs are horizontal (fig 21) and the arm rests are both at the same
height and angle. Place the nuts on the underside of the tray into the required holes in the tray arms.
The tray can then be locked in place by rotating the bars to grip underneath the arm rest.
WHY?
Tray position can affect your child’s hand function. Often the best height is waist height but consult your
therapist to choose the best position for your child. You can alter the tray angle to give an inclined surface
or a flat surface even when the chair is tilted.

The back column angle
HOW?
First loosen the black wing nut (fig 22) and set the back column angle by rotating the large yellow knob
(fig 23). Turning the knob clockwise will make the back column go forwards, turning it anti-clockwise will
make the column go backwards. Remember to re-tighten the black wing nut again to lock the back column.
WHY?
Setting the back angle independently of the seat allows you to control the angle of the hips. For children
with an extensor thrust, you have the facility to close the angle and achieve the right posture. For children
with low tone however, you can open up this angle to offer more support to their upper body and head.
Fig 22
Tilt-in-space
HOW?
To alter the angle of the chair, lift the lever underneath the
left side of the seat and set the chair to the required position
(fig 24). Releasing the lever will lock the chair in that posi-
tion. Tilt–in-space keeps the child’s position exactly the same
within the chair.
Fig 23
WHY?
By altering the position of your child in space, you can help them to perceive the environment that
surrounds them in different ways and thereby help their cognitive development. By putting the chair into
prone you may improve your child’s head control and arm function.

Adjusting the chair height
HOW?
When the chair is empty:
To lower the seat, depress the pedal and push down firmly on the centre of the seat (fig 25).
Lowering the seat is usually easier when standing at the side (fig 25).
Minimum height is only achieved when the seat is level or slightly prone.
TIP
When the chair is occupied:
To lower the seat hold the handle bars and depress the pedal. Gently guide the chair to the desired
height. If the child is not heavy enough to cause the seat to lower unassisted, apply gentle pressure
to the top of the hip pads.
To raise the seat, simply depress the pedal and lift the handle bars gently.
Fig 25
To raise the seat, depress the pedal and the chair will
automatically rise. If this does not happen, simply lift
the handle bars gently.

Multi Gamma
Multi-grip™ Headrest
WHY?
The headrest should be positioned to support the child’s head. For children with good head control,
straighten out the multi-grips to provide a fairly smooth back surface. Never use the headrest to force a
child’s head into position as this will cause discomfort and can trigger reflexes which will result in poor
posture. The unique Multi-grip™ supports can be moulded to the shape of the child and can be splayed
at the end to support under the child’s chin.
Fig 14
Multi-grip™ Thoracic HOW?
Ensure the chest strap is used. Velcro should overlap by at least 3 inches
(7.5 cm)
.
To adjust the height of the thoracic supports loosen the thumb screw on the back column adjust to the
desired height and re-tighten. The width of the Multi-grip can be adjusted by loosening the bolts with the
Allen key provided then using your hands to create the contour you want. Tighten to finger tight only.
These fingers can be re-contoured as often as you like to vary the support offered.
Multi-grip™ Thoracic WHY?
The chest strap and Multi-grip™ thoracic support are designed to hold the child’s body straight whilst
sitting. Gravity then helps to develop their bones and their muscle tone. Ensure two fingers space between
the thoracic supports and the child’s armpit and a finger width from the child. Floppy children should be
supported by a combination of thoracic supports and hip supports to keep the spine straight. This helps to
prevent the child sitting with a curved spine.
A Multi-grip™ version of the Gamma
is available. Multi-grip™ supports
are positioned for the Headrest,
Thoracic and Hip Supports.
Multi-grip™ Headrest
HOW?
Using the Allen Key provided loosen
the bolts, then use your hands to
create the contour you want. Tighten
to finger tight only. These fingers can
be re-contoured as often as you like
to vary the support offered. These
“fingers” make it easy to cradle the
child’s head. No other products offer
this versatile option. Take the time
to practise with the “fingers” to
create a contour as individual as
each child.
Multi-grip™ Hip Support HOW?
To adjust the height of the thoracic supports loosen the thumb screw on the back column adjust to the
desired height and re-tighten. The width of the Multi-grip can be adjusted loosening the bolts with the Allen
key provided then use your hands to create the contour you want. Tighten to finger tight only. These
fingers can be re-contoured as often as you like to vary the support offered.
Multi-grip™ Hip Support WHY?
The Multi-grip™ Hip supports offer more control over the position of the hips and upper leg movement.
Secure the child by using the 45° pelvic strap before you begin to make any other adjustments.
Ensure the belt is adjusted for each child and for changes of clothing.
Ensure the straps are routed under the hip pads. Ensure a fingers width between the belt and the
child to prevent over tightening or the child moving to an inappropriate position.
Do not use this product if you suspect the Multi-grip™ Gamma is faulty or broken.
