1. INTRODUCTION
Netti III HD is a comfort wheelchair meant
for both indoor and outdoor use. It is tested
to DIN EN 12183:2009. 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 III HD is a wheelchair designed
for users with the need for comfort and relief.
The combination between the seating system
and the ergonomical solutions in the frame
construction, oers many possibilities for
adaptation and adjustments.
The wheelchair is constructed for indoor and
outdoor use, and oers the possibility to
vary the sitting position from activity to
rest using tilt and recline functions.
Max user weight: 160 kg.
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 III HD wheelchair is tested
at TÜV SÜD Product Service GmbH
in Germany, following the European
Standard DIN EN 12183:2009. 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
maintenancedoneforemostdecides 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

materials - to make recycling easier.

To mount the main wheel remove the quick
release bolt from the hub bushing, lead it
through the centre of the main wheel and
into the hub bushing while pressing the
knob in center.
To check that the main wheel is
properly attached to the hub, remove
the nger from the central knob and
pull the main wheel.
If the main wheel doesn’t lock, don’t
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 in
centre above the wheel.

Language: English Model: Netti III HD Version: February 2013
6.4 Front castors
To take of
• Press the release button under the front
fork.
To mount
• Lead the quick release axle into the
bearing house. Pull the fork slightly to
ensure that the fork is fully locked.
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 there is several models of
both front castors and front forks to
choose between. For to change the
front castors or front fork - unx the
wheel and place 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. Unx the two
screws on the inside of the frame enough
to adjust the 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 can not be adjusted
in height.
Check the position of the anti tip.
6.6 Seat height at the rear
The seat height at the rear depends on:
• Size of main wheel.
• Position of main wheel.
Main wheel
Unx the hub bushing, including washer and
nut, and mount it in required position in the
main wheel bracket.
2 pcs 24 mm open-end spanner
Make sure that the nut on inside of
frame totally wreathes the wheel
bushing.

18
Language: English Model: Netti III HD Version: February 2013
When the seat heights changes ensure
that the main wheels are placed such
that the frame tube is parallel with
the ground.
The risk for tipping increases when the
main wheel is moved forward in the
main wheel bracket.
Check the position of anti tip.
Readjust the brakes. (See chapter 6.17).
Readjust the angle of the bearing
house. (See chapter 6.5)
6.7 Backrest
• Unfold and lift the back rest up and t the
gas strut into the bracket.
• Secure the back rest by pushing the locking
bolt in from the side, through the bracket
and gas strut head.
6.8 Adjusting seat depth at
the rear
The seat depth can be adjusted 10 cm in the
rear and 10 cm in front.
Adjusting seat depth in the rear:
• The back rest hinge has 5 holes with 2,5 cm
distance between them.
• The seat depth can be adjusted from 40-50
cm (Measured from front of seat plate to
back rest tube without back rest cushion).
• Onto the frame under the chair there is
mounted an extra locking head for the gas
strut.
• The short locking head covers seat depth
40 cm, 42,5 cm og 45 cm.
• The long locking head covers seat depth
45 cm, 47,5 cm og 50 cm.
(There is also a long back rest hinge which
covers longer seat depths. See chapter 5).
• When changing the position of the back rest
hinge, also remember to change the position
of the gas strut under the chair. The bracket
has 3 holes. When the back rest hinge is
set in the shortest position, the gas spring is
placed in the front hole using the short
locking head. For each position the back rest
hinge is pulled out, the gas spring is moved
one hole towards the rear. When the gas
spring reaches the rearmost hole with short
locking head, change to long locking head
and start from the front hole again.

19
Language: English Model: Netti III HD Version: February 2013
When using the comfort seat plate it
is recommended to change seat plate
when changing seat depth. The seat
plate comes in depth: 40 cm, 43 cm &
46 cm.
By using the adjustment straps in the
rear you can gain a few cm on the
depth.
Seat depth in the rear is adjusted as follows:
• Release the tilt gas strut by tilting the seat
all the way forward.
• Pull out the locking bolt for the backrest,
and place the back rest forward in the seat.
• Remove the screws holding the back rest
hinge, and set the backrest to the required
position. Do both sides at the same time.
• Place the screws back and x them.
• Also remember to move the gas strut as
described earlier in this chapter.
When adjusting the seat depth at the
rear the screw in the backrest hinge
must be tightened with 14 Nm
6 mm Allen key
13 mm open-end spanner
If the user requires other back rest
angles than what is standard, it is
possible to change the position of the
gas strut in three positions under the
chair in front.
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).
6.9 Adjusting seat depth at
the front
It is possible to adjust the seat depth up to
10 cm at the front. Do the following:
• Unx the screw holding the pull out piece
for the foot support.
• Set the pull out piece to the required
position.
• Fix the screws, tighten them with 25 Nm
6 mm Allen key
By setting the pull out pieces to dierent
positions, it is possible to compensate
for a rotated pelvis or dierent length of
thighs.
6.10 Anti tip
• Adjust the anti tip so that it doesn’t stick
outside the radius of the wheel.
• Pull the anti tip out / rearwards from chassis.
• Turn it down 180°.
• Lock it in position by moving forwards with
spring tension.

20
Language: English Model: Netti III HD Version: February 2013
The anti tips are delivered adjusted
according to ordered main wheel size in
standard position. If other adjustments
are carried out, anti-tips have to be
adjusted accordingly.
Adjusting anti tip
The anti tips must be adjusted whenever
position or dimension of main wheels is
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:
• Unx 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 thesame procedureon theoppositeside.
6 mm Allen key
Check that both anti tips have the
same length. The gap between the
anti tip wheels and the ground must be
max. 3 cm.
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.
6.11 Adjusting arm supports
•Turn the release handle to the side and hold.
• Adjust the armrest to the required height
and release the handle. Lift or lower the
armrest slightly until it locks.
The armpad and locking screw are set
in the middle position. This can be
