1. INTRODUCTION

Netti II is an all round comfort wheelchair
meant for both indoor and outdoor use.
It is tested to DIN EN 12183:2014.
The tests were carried out by TÜV SÜD
Product Service GmbH in Germany

In Alu Rehab we believe that wheelchairs
should be chosen based on a thorough
assessment focusing on the needs of the
user and demands from the environment.
Therefore it is important to know about
the possibilities and restrictions of the
wheelchair. Netti II is a wheelchair
designed for users with the need for
comfort and relief. The combination
between the seating system and the
ergonomically solutions in the frame
construction, offers many possibilities for
adaptation and adjustments.

The wheelchair is constructed for indoor
and outdoor use, and offers the possibility
to vary the sitting position from activity to
rest using tilt functions.

Max user weight 125 kg.

Netti II is not approved for being
used as a seat in a vehicle.

When mounting accessories such as
power kit etc, the weight of the
accessories must be subtracted from
the max user weight.

Specications varies between

countries.

1.3 QUALITY AND
DURABILITY

The Netti II wheelchair is
tested at TÜV SÜD Product
Service GmbH in Germany,
following the European
Standard DIN EN 12183:2014.
As manufacturer, Alu Rehab A.S evaluates
the test to be equal to 5-6 years of normal
use of the chair. The disability of the user
as well as the level of maintenance done
foremost decides the durability of the
wheelchair. Thus, the durability will vary
depending on these two factors.

1.4 THE
ENVIRONMENT
AND WASTE
DISPOSAL

Alu Rehab and its suppliers

• That Alu Rehab’s products are
ensured a long service life and a high
degree of flexibility - to benefit the
environment and economy.

• That all packaging can be recycled.

• That the wheelchair was designed to
be separated into its component
materials - to make recycling easier.

Contact your local recycling
agent to get correct information
how to handle in your area.

Netti II is designed for temperature
range from -10°C to +40°C

through the centre of the main wheel and
into the hub bushing while pressing the
knob in centre.

To check that the drive wheel is
properly attached to the hub, remove
the finger from the central knob and
pull the main wheel.

If the drive wheel does not lock, do
not use the wheelchair but contact
your dealer.

Sand and sea water (salt used for
gritting in the winter) can damage
the bearings of the main wheels.
Clean the wheelchair thoroughly
after exposure.

6.3 FRONT FORK

Front forks come as standard
with quick release axles. The
front fork is easily removed
by pressing the knob on top
of the QR on top of the
bearing house.

Sand and sea water (salt used for
gritting in the winter) can damage the
bearings of the front castors. Clean the
wheelchair thoroughly after exposure.

6.5 SEAT HEIGHT AT THE
FRONT

The seat height depends on:

• Size of front castors.

• Size of front fork.

• Check the angle of the castor bearing
house.

In chapter 5 the overview shows that you
can choose between several models of both
front castors and front forks. To change the
height of the front castors - unfix the wheel
and replace it in the required
position in the front fork.

Angle of bearing house
Correctly adjusted angle of the front fork is
important to achieve proper manoeuvring
qualities of the wheelchair. Unfix the two
screws on the inside of the frame enough to
adjust the eccentric nuts. Angle the bearing
house, so that it is 90° relative to the
ground. Tighten the screws with 16 Nm

1 pc 5 mm Allen key
The bearing house cannot be height

adjusted.

Check and adjust the position of the

anti tip if necessary.

6.6 SEAT HEIGHT AT THE

castors are adjusted vertical to the
ground.

The risk for tipping increases when the
drive wheel is moved forward in the
drive wheel bracket.

Adjustment of the back angle

• Unscrew the screw as shown on the
picture. Reposition it to desired position.

• Tighten the screw.

To ensure safe locking it is recommended to
adjust the inner nut to have one of its sides
parallel to the back hinge. See picture.

6.8 ADJUSTING THE SEAT
DEPTH

The seat depth can be adjusted both in the
back and in the front of the seat. Adjustments
are done to give the user a comfortable
seating position with proper lumbar support
while the knee joint is aligned with the leg
support knee joint.
By adjusting the seat depth the chair balance
and the driving characteristics may change.

A well balanced chair is easy to drive without
easily tipping backwards. Always start with

adjusting the seat depth backwards, then
adjust the leg support fixing bracket to make
the leg support knee joint align with the user
knee joint. If necessary the driving wheel
position also needs to be change.
The seat depth can be adjusted 100 mm in the
rear and 100 mm in front.

ADJUSTING SEAT DEPTH AT

THE REAR

Adjusting seat depth at the rear:

• The back rest hinge has 5 holes with 25 mm
distance between them.

• The seat depth can be adjusted from 400­500 mm (Measured from front of the seat­plate to backrest tube without cushion).

• Tilt the seating unit most forward.

• Push the release bar of the backrest down,
and fold the backrest forwards on to the seat.

• Remove the screws holding the back rest
hinge and reposition it to desired position.

• Tighten the screws. Same position on both
sides!

6 mm Allan key 13 mm open end spanner

When using the comfort seat plate it
is recommended to change seat plate
when changing seat depth. The seat
plate comes in depth: 400 mm, 430 mm
& 460 mm..

By using the Velcro adjustment straps
in the chair-back you can gain a few cm
on depth.

When adjusting the seat depth at the
rear, the screw in the backrest hinge
must be tightened with 14 Nm

When changing seat depth, you also
change the tipping point of the chair.

This can be prevented by changing the
position of the main wheel in the main
wheel bracket. (See chapter 6.6).
Adjust anti-tippers accordingly chapter 6.10

6.9 ADJUSTING SEAT DEPTH
AT THE FRONT

It is possible to adjust the seat depth up to
100 mm at the front. By restless users the
extension piece should not be pulled out
more than 50 mm. Do the following:

• Unfix the screw holding the extension piece
for the leg support.

• Set the extension piece to the required
position.

• Fix the screws, tighten them with 25 Nm

6 mm Allen key.

By setting the extension pieces to
different positions, it is possible to
compensate for a rotated pelvis or different
length of thighs.

6.10 ANTI-TIP

• Adjust the anti-tip so that it does not stick
outside the radius of the wheel.

• Pull the anti-tip out / rearwards from chair.

• Turn it down 180°.

• Lock it in position by letting it move
forwards with the spring tension.

The anti-tips are delivered adjusted
according to ordered main wheel size
in standard position. If other adjust-
ments are carried out, anti-tips have to
be adjusted accordingly.

Adjusting anti-tip

The anti-tips must be adjusted whenever the
position or dimension of the main wheels are
changed.
Correctly adjusted anti-tips should be
positioned just on the inside of the radius
of the main wheel. Anti-tips are adjusted as
follows:

• Unfix the locking clamp on the anti-tip bar
using an Allen key.

• Pull or push the bar to required position.

• Fix the locking clamp.

• Do the same procedure on the opposite
side.

6 mm Allen key

Check that both anti-tips have the same
length. The gap between the anti-tip
wheels and the floor must be 20 - 30 mm.

If the anti-tip is positioned on the
outside of the main wheel radius, it
will interfere with curbs and stairs.

The anti-tip should always be used
for the safety of the user.

7. SEAT ANGLE / TILT
AND BACK ANGLE /
RECLINE

7.1 SEAT ANGLE

The seat angle is regulated using the release
handle mounted on the push bar.
The seat unit can be tilted from -9° to +16°.

7.2 BACKREST ANGLE

The backrest angle for Netti II is adjusted to
one of the following 3 positions:

n Backrest angle 83° - steep back angle for

users with corset or lordosis. The back can
be adjusted as optimal as possible using
the Velcro bands in the back.

n Back angle 97° is standard position for

normal support.

n Back angle 107° is used for users with need

for more open hip angle. Coxit seat cushion
can also help to achieve this.

To ensure correct function of the

wires, these must never be taut.

The seat angle must not be adjusted

without using the anti-tips.

The release handle has the following label:

Tilt

Risk for tipping.

Check the position of anti-tip.

When chair back extension is
mounted, the tipping risk increases. If
necessary it should be improved by moving
the main wheels further back. Always use
anti tippers when tilt function is being
activated.

7.3 KEY WORDS REGARD­ING TILT FUNCTION OF
STATIC COMFORT WHEEL­CHAIRS,

Tilt is the basic benefit of a comfort
wheelchair. It allows for varying seating
positions during the time in the wheel­chair.

Tilting the seating unit of the wheelchair is
mostly used to give the user varying sitting
positions and preventing sliding, shearing
and thereby pressure sores.

7.4 DECREASE THE POSSIBIL­ITY OF SLIDING, SHEAR AND
PRESSURE SORES:

Use the tilt function to give the user
variation of the seating positions.

MAKE SURE THAT THE USER IS
SAFE WHEN THE TILT FEATURE
IS BEING ADJUSTED:

This is a great benefit for the user: The care
giver is able to establish eye contact with
the user when the tilt function is going to
be used. The care giver is also able to com­municate with the user before the tilt func­tion is used. The user will feel more safe
when he/she is aware that the seating unit
of the wheelchair is going to be tilted.

7.5 OPERATING TILT HANDLE:
TILTING THE SEATING UNIT

Press the left handle on the push bar and
put pressure to the push bar to tilt the
seating unit with one of your hands, while
you have eye contact with the user and put
the other hand on the arm support.

The correct relative angle between the
body parts remain the same when the seat­ing unit is tilted.

Wherever you let the handle loose, the
seating unit will stay in this position.

To bring the seating unit up, press the
handle and the tilt cylinder will assist you
lifting the seating unit up.

A backward tilted seat unit gives a
steeper seating angle in relation to the sur­face, and prevent sliding of the wheelchair
user.
A forward tilted seat unit brings the user
in a position where activities - for instance
by a table or by standing up from the
wheelchair, is supported.

The tilt handle and the tilt sign is on the
push bar - shown on the previous page.

Never leave the user alone when the
seat is tilted forwards. The user can slide
forward.

9. MANOEUVRING

9.1 GENERAL TECHNIQUES

The weight and balance of the chair
influences the manoeuvring ability of the
wheelchair.

The weight, size and sitting position of
the user are also influencing factors. Also
the position of the wheels will influence
the driving performance. The more weight
placed over the main wheels, the easier it
is to manoeuvre. If heavy weight is placed
over the front castors, the chair will be
heavy to manoeuvre.

Companion: If the user is left alone in

the wheelchair, always lock the brakes and
secure that the anti-tips are turned down.

Parking:

Increase the underneath support of the
wheelchair by moving the chair about 100
mm backwards making the front castors
turn forward.

Step approach:

Always approach the step in slow motion
preventing the front castors to hit the step
with force. The user could fall out of the
chair by the impact. The front castors could
brake.

Driving forward down steps/ sidewalks

Be cautious that you do not drive down
steps higher than 30 mm. The leg supports
may hit the ground first. Thereby you might
loose the control and the leg supports may
brake.

Driving on soft, rough or slippery
ground can make safe manoeuvring more
difficult as the wheels may loose traction
and it is difficult to control the wheelchair.

EMERGENCY EXIT

The total chair width of Netti II with seate
width 500 mm is bigger than 700 mm,
it may therfore have difculties passing

through emergency escape exits.

9.2 DRIVING TECHNIQUES

- STEP UP -

Companions, drive up a step forwards:

• Check that the anti tip is turned up

• Angle the wheelchair backwards.

• Lift the push handles while pushing the
chair onto the step.

Turn the anti tip down.

Users, drive up a step backwards:

This technique is only useful if the step is
very low. It also depends on the clearance
between the foot plates and the ground.

• Check that the anti tip is turned up.

• Drive the chair backwards towards the
step.

• Make a firm grip on the push rims and
move the body forward while pulling.

Turn the anti tip down.

Companions, drive up a step backwards:

• Check that the anti tip is turned up

• Pull the chair backwards next to the
step

• Angle the wheelchair backwards,
moving the front castors slightly up in
the air.

• Pull the wheelchair up the step and go
backwards long enough to put down
the front castors on the step.

Turn the anti tip down.

away from the step.

• Put the front castors down on the ground.

Turn the anti tip down.

9.4 DRIVING TECHNIQUES

- SLOPE -

Important advise for driving down and up
hill avoiding the risk of tipping.

Avoid turning the wheelchair in the

middle of a slope.

Always drive as straight as possible.

It is better to ask for assistance than

taking risks.

Driving uphill:

Move the upper part of the body forwards
in order to maintain the balance of the
chair.

Driving downhill:

Move the upper part of the body back­wards to maintain balance of the chair.
Control the speed of the chair by
clutching the push rims.
Do not use the brakes.

• Tilt chair forward.

Using a lift:
Before transfer to chair:

• Tilt the chair back

• Remove the head support

• Remove the leg supports

• Open the back rest angle slightly

• Replace the components when
transfer is finished.

Never stand on the foot plates due to

the risk of tipping the chair forwards.

9.8 POINT OF BALANCE

Adjust the point of balance by changing
the position of the main wheel in the main
wheel bracket.

• Move the main wheel hub and the
main wheel. (Chapt. 6.6)

• Adjust the brakes. (Chapt. 6.17)

2 pcs 24 mm open-end spanner

5 mm Allen key

When the main wheels are moved
forward, it will be easier to manoeuvre
the wheelchair, but the risk of tipping
backwards increases.

The point of balance can also be
changed by adjusting the seat angle
and/or angle of backrest.

It is recommended to use the anti tip.

Check that the main wheel and quick
release are locked properly. (Chapt 6.2)

9.9 LIFTING THE
WHEELCHAIR

• The unfolded wheelchair should be lifted
from 2 persons holding on to the frame
and push bar only.
It is marked with the below symbol where
it should be lifted.

Never lift the wheelchair holding on to
the leg-, arm- or head supports. They
may detach and the wheelchair may fall
and get damaged.

Never lift the wheelchair with a user
in it.

9.10 CHANGE OF CAMBER
ANGLE

Drivewheels are as a standard mounted
without camber angle.
The camber angle can be changed by
installing the bracket ( accessory) between
bearing house and nut.

2 pc 24 mm open-end-spanner.

9.11 PUSH RIM

Netti wheelchairs are delivered with
aluminium push rims as standard. The
material and distance to the main wheel
influences the ability of the user to grip.
Contact your dealer to get information
about push rims that fit your chair.

Alternative push rims may give better
grip, but the friction may increase.
When using the hands to stop the
chair, the risk for burning of the hands
increases.

A squeezing and trapping hazard of the
fingers may occur when passing
through narrow passages and if the
fingers come between the spokes.
To avoid this risk, we recommend spoke
protectors as accessory.

If you want/need to change push rims
or increase/decrease the distance
between the push rims and the wheel,
please contact your dealer.
