1. INTRODUCTION
Netti Mobile is an electrical comfort
wheelchair meant for both indoor
and outdoor use. It is tested to
DIN EN 12184:2009. 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 as-
sessment 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 wheel-
chair. Netti Mobile is an electrical class B
wheelchair designed for users with the need
for comfort and relief. The combination
between the seating system and the ergo-
nomic 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.
Max user weight: 140 kg.
Specifications varies between
countries.

2.How to use this manual
This manual supplements the service in-
formation published in the user manual.
It should be read in conjunction with the
spare parts catalogue and the user manual.
Where appropriate it should also be read
together with the manuals and installation
information published by the manufactur-
ers of control systems for powered wheel
chairs, the batteries and the battery charg-
ers used on Netti Mobile.
Particular attention should be paid to the
following sections of the user manual:
For assembling and adjustment information:
section 7
For Shark control systems: section 8.1.1
For DX2 control systems: sections 8.2.
To replace batteries: section 10.3
For general maintenance section 11
3. Third party manuals
We recommend you refer where appropriate
to the service and installation manuals that
are published by the manufacturers of the
power chair control systems, batteries and
battery chargers used on this chair.
For Netti Mobiles equipped with Dynamic
Shark or DX2 control systems we recom-
mend you download the DX system manual
from dynamiccontrols.com and pay close
attention to the warnings it contains. The
notes in sections 2.1., 2.2 and 3.1 are useful
guidance for power chairs equipped with
any control system
4. Major service
The following check list describes the
checks that must be performed as part of
a major service of a Netti Mobile. The cor-
responding box must be ticked to confirm
that the check has been performed. After
the check list has been completed it must
be signed and dated on behalf of the organ-
ization that carried out the major service.
Service interval: For normal domestic use
a major service should be performed at
least once every 12 months. A major ser-
vice should be performed more frequently
if the power chair is used intensively or if it
is exposed to dicult conditions that might
cause premature wear or failure.
A major service must be performed if the
power chair has been known to be misused
or if it has been involved in a collision which
could have resulted in substantial damage
to the chair.
Contact your local recycling agent
to get correct information how to
handle in your area.

CHECK CHECK BOX
Motors: clean them, check for leakage of lubricant. Check bearings ca-
bles and connectors.
Check that the park brakes on both sides click when the joystick is
moved out of neutral with the park brake lever in the drive position. If
they do not click this is a sign of a serious failure and the chair must not
be driven again until this fault has been corrected.
The motors and gearboxes should not make loud noises or show signs
of burning. If the motors smell of burnt insulation (this is a very strong
smell), they will have been used outside of their normal duty. They will
need to be replaced immediately. Claims for burnt out motors will not
be accepted under warranty unless there are exceptional circumstances.
Check for normal function of the motors by doing a driving test on flat
ground for 2 minutes. If the motors or the park brakes become hot to
touch during such a short time there is probably a serious fault either
with the motors or the park brakes that must be investigated and recti-
fied.
Notes: Motors and gearboxes are electromechanical components. It is
normal to hear noises from the motors used on Netti Mobile when during
normal operation. The standard we work to allows for up to 65dB(A)
which might sound loud in a quiet environment such as some hospital
wards .
In some weather conditions and at very low speeds sometimes used for
moving a chair in tight spaces you might hear an occasional squeaking
sound that goes away as soon as the chair drives at normal speeds. This
is normal for this class of motor, it comes from the very small clearance
between park brake and the motor housing liner.
If you change a motor on one side you might notice the chair then veers
to one side when the joystick is pushed full forward. If this happens the
veer compensation parameter will need to be adjusted. Refer to the con-
trol system manufacturer’s installation manual for the correct procedure.
Veer occurs when there are motors on the chair from dierent produc-
tion batches. In severe cases it may be necessary to change the motors
on both sides even if only one of them is defective.

CHECK CHECK BOX
You may notice that even if a chair does not veer when driving forward
it does veer when driven backwards. This is due to the commutation an-
gle of the motors being optimized for driving forward. This is normal for
this class of motor. If veer in reverse is a matter of great concern it will
be necessary to adjust the veer parameter to allow some veer forward
and backwards or to change the control system to a gyro module. This
option is available on DX2 chairs at additional cost.
Tyre pressure –(pneumatic only) should be 3.5 bar
Tyre condition - check for cracks or abnormal wear.
Cables - check that the insulation on the cables is intact and that there
are no signs of heat damage. Check that any cable that might move
during normal operation of the chair remains flexible. If there are any
signs of work hardening, (such as a length of a cable that has become
bent sti and cannot be straightened the cable has been checked more
closely and replaced if necessary.
Tie down any loose cables, free any trapped cables and check they are
not being constrained within the relevant minimum bending radii. Note:
for Dynamic bus cables: 50mm for continuous flexing and 30mm for
occasional flexing. Check that any bus cables attached to a controller
mounted on a swing-away arm do not be become bent through a radius
of less than 50mm at any point during the movement of the swing-away
arm. To achieve this you may need to modify or replace the arm rest. In
case of diculty, contact Alu Rehab customer services for advice.
Electronics control system modules: check they are dry, check all con-
nectors are intact and inserted properly and that they are not loose.
Check all chair functions
User controllers, (such as joystick remotes): clean then check the case
for damage and cracking. Make sure all connectors are secure and are
fixed firmly in the casing. If there is any sign of movement the controller
should be considered to be unsafe. If there is a joystick check the gaiter
is not damaged as this will allow liquid to contact the electronic pcbs.
Check that the icons on any manual switches are legible. If any of these
checks are failed, exchange the user remote control for a new one.

CHECK CHECK BOX
Batteries - check the battery terminals together with the connectors
and cables in the battery circuit. Check the battery cases for leakage.
Check that the individual battery voltages when fully charged are the
same. If they are dierent this is an indication that at least one of the
batteries is defective and that further investigation is required.
If necessary use a high quality battery tester appropriate for the type
and capacity of the battery fitted. Contact Alu Rehab customer servic-
es for recommendations.
Check inside the electronics enclosure. Make sure the interior is dry
and that all screw terminals are tightened properly and secure. Check
the lid is fitted securely after you have put it back
Charger – Connect the battery charger, make sure it is functioning cor-
rectly according to the manufacturer’s manual. Charge the batteries to
full before shipping the chair.
Fuse – check it has not blown using a multimeter, replace it if neces-
sary.
Check all moving parts are functioning correctly. Clean hinges and
lubricate with acid free bicycle oil as appropriate.
Clean all wheels. Check the wheel hubs are fixed firmly to the motor
shafts. If there is movement between a wheel hub and the motor
shaft, tighten the fastenings. If this doesn’t eliminate the movement
the wheel hub will need to be replaced. If there are signs of corrosion
at the motor shaft remove the wheels and put a little copper grease on
the motor shafts before putting the wheels on again.
Note: if you have to remove the drive wheels for any reason, put a little
copper grease on the motor shaft before you put it the wheel back on.
This helps protect the motor shaft from corrosion.
Check the caster wheels for excessive movement and make sure they
are in serviceable condition. Check the anti-tips are intact and func-
tioning safely. If there is any doubt as to the safety of the wheels or
the anti-tips they must be replaced.

CHECK CHECK BOX
Park brake release mechanism: check if it is engaging and disengaging
the park brakes properly.
Check the cables for damage and they are not sticking.
Check the electronics inhibits driving when the park brakes are manu-
ally released.
Screws and washers - check that the screws tighten properly, and that
screws and washers are intact.
Wheelchair frame and all load bearing mechanical components:
Clean and check for cracks.
Warning: if any cracks are found in the frame or any other load bear-
ing mechanical components they must be scrapped and replaced. Do
not attempt to repair any cracks found in load bearing components.
Accessories: check any accessories, manual and electronic. Replace
any faulty components.
Test drive – with load up to maximum capacity. Check the chair can
climb a 50mm obstacle on a surface with good traction.
