1. INTRODUCTION
Netti 4U Base is a wheelchair chassis meant
to function as a base for external seating
systems and modular seats, as well as for
the Netti Seating System.
Netti 4U BASE with Netti Seating System
has been 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.
The wheelchair is constructed for indoor and
outdoor use, and offers the possibility to
vary the sitting position from activity to
rest using tilt and recline functions.
Max user weight: 135 kg.
When mounting accessories such as
power kit, external seating systems etc.,
the weight of the accessories must be
subtracted from the max user weight.
Specifications varies between
countries.

1.1 AREAS OF USE/INDICATIONS
FOR NETTI 4U BASE
Netti 4U Base is a comfort wheelchair
chassis to be used in combination with
external modular seats and seating systems,
alternatively with solutions from Netti Seating
System. The seating system is chosen based
on the needs of the user, and the Netti 4U
Base will provide added stability through a
wide range of leg supports, arm supports and
head supports. In addition, the Netti 4U Base
provides unique tilt and recline functions in
combination with very good manoeuvring
properties.
1.2 CONTRAINDICATIONS
Netti 4U BASE is not suited for persons with
a strongly enhanced muscular spasticity. In
this case we recommend the Netti Dynamic
System which offers a construction that
follows the movement pattern of the user.
Ignoring this advice could in unfavourable
circumstances lead to the deformation or
fracture of metal parts in the area of the back
tube, the leg supports or the arm supports.
1.3 QUALITY AND DURABILITY
The Netti 4U Base 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 wish to
protect the environment.
This means:
• That we avoid using
environmentally
harmful substances and processes to
the greatest extent possible.
• 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 you area.
Netti 4U BASE is designed for
temperature range from
-10°C to +40°C.
