and demands from the environment. Therefore

it is important to know about the possibilities

and restrictions of the wheelchair.

for users with the need for comfort and relief.

The combination between the Netti seating

system and the ergonomical solutions in the

frame construction, offers many possibilities

for adaptation and adjustments.

1.1 Quality and durability

tested at TÜV Product Service GmbH in

Germany, following the European Standard

EN 12183:1999. 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 users 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.

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.

• That the wheelchair was designed with

many different auxiliary functions - to

improve the working environment for

staff at instutions and hospitals.

Recline Tilt

Risk for tipping.

Check the position of anti tip.

Don’t leave a user in the wheelchair

when it is tilted forward.

7. MANOEVRING

7.1 General techniques

The weight and balance of the chair

influences the manoevring qualities of the

wheelchair. The weight, size and sitting

position of the user are also influencing

factors. The position of the wheels will in

addition influence the manoevring qualities.

The more weight placed over the main

wheels, the easier it is to manoevre. If heavy

weight is placed over the front castors, the

chair will be heavy to maneuvre.

Companion:

If the user is left alone in the wheelchair,

always lock the brakes and check that the

anti tips are turned down.

If the wire is too loose:

Adjust the foot screw all the way in. Tighten

the wire by loosening the wire clamp before

pulling the wire further through it. Tighten

the wire clamp, and adjust the foot screw out

again.
