In general
The Armon Pura is a fully mechanical arm support. It has a unique mechanism that compensates the weight of the
user’s arm. Thereby the arm feels weightless. People with limited strength can then use the strength they have
got left to lift their arm again. The weight compensation is steplessly adjustable through the controls.
The arm support does not take over any function. It only supports the arm. The user makes the movements
him/her self, using the strength he/she’s got left. This is beneficial for the muscles and joints of the user. Our
products follow all the movements and support the arms in a 3D area.
The Armon Pura can compensate an arm weight from appr. 850 grams up to appr. 3400 grams. The Pura light can
compensate an arm weight from app. 600 grams up to appr. 2500 grams. It is possible to mount all types of
Armon braces.
The Armon Pura weighs approximately 5500 grams.
Intended use
The Armon Pura is a dynamic arm support for users who are (still) able to independently level their arm and
should only be used to support the weight of an arm with a maximum weight of 4000 grams.
Left, right or both arms can be supported. It is important to choose the right brace for optimal functionality.
The Armon pura can be mounted on a wheel chair, working chair or on a stand.
The Armon Pura can also be used as an arm support in working situations to lighten strenuous working conditions
and thus preventing arm, neck and shoulder injuries.
Parts of the Armon Pura
The Armon Pura has a rotation frame which
is also the mounting point.
The end of the upper arm is where the brace is mounted.

You can mount the Armon Pura simply by sliding it onto a
bracket or the universal connector. You can than fixate it on
the right position by turning the fixation screw in a clockwise
direction. Make sure the screw is tightened firmly before
using the Pura.
For dismounting, follow the above steps in a reverse order.

ATTENTION! If you are not comfortable or sure how to properly place your arm into the Brace, please
contact your supplier. If you are not able to independently level your arm when the compensation force drops
out, you should not be using this product.
Braces
Armon Products has four different types of braces and every type
is available in three different sizes. The brace is the part where
you put your arm in. It is the connection between the arm support
and the user. The braces are exchangeable between all our arm
supports.
The braces available in ascending order of functionality:
The more advanced the brace, the more functionality you can achieve with this brace. The right individual
adjustment of your brace should only be done by qualified and therefore trained specialists.
Placing the arm
Place the arm in the brace in the following way:
•The under arm should lay in the brace
•The upper arm should be placed against the upper arm support, not far above the elbow.
•The elbow should be free.
•The upper arm support consists out of non-allergic rubber with a stainless-steel frame in it that can be
bent in any direction for optimal comfort for the user

Manual Armon Pura Version 1.4 Date: August 2018
Adjusting the force
You can adjust the level of compensation (force) of the Pura steplessly, to compensate the weight of every arm.
This can be done with or without the arm placed in the Pura. The force is adjusted by
turning the yellow knob at the back of the Pura.
Turning the yellow knob moves the
white indicator through the scale
division. On the scale division are
numbers. The numbers refer to a
level of weight compensation.
An arm weighs approximately 5 % of
your body weight. In the table on
the next page, in the first three
columns, you can see how much an arm weighs at a certain body weight.
In the fifth and sixth column you can see the amount of force that is given by the Pura at which number. This
gives an indication for adjusting the right level of compensation. In practice users seldom compensate 100% of
their arm weight. Most common is around 80% compensation. All figures below give are based on average
statistics.

Adjust the level of weight compensation by:
•Turning the knob in clockwise direction:
The Pura gives more compensation
•Turning the knob in counterclockwise direction:
The Pura gives less compensation
Maintenance:
The Armon Pura does not require any particular maintenance except for cleaning. (page 8)
Troubleshooting:
The Armon Pura has been designed and manufactured using highly advanced technology and first-class
components to ensure a reliable and efficient performance. However, should you meet with any operational
problems; it is recommended that you consult your local Armon Products distributor.
CAUTIONS:
•Only Armon Products BV authorized technicians may carry out service on the internal parts of the
equipment.
•For repairs and further information, contact your local Armon Products dealer or authorised service
centre.
Installation:
The installation of the Armon Pura should only be done by qualified and therefore trained specialists. These
specialists will receive a certificate after completing a training. To ensure the quality of the installation and
individually made brackets their training and certificate should be updated on a yearly bases. This is to ensure
proper use and complete safety for the patient.
Safety:
•The arm support works with a spring compensation mechanism. Hence it gets the energy for the
compensation out of springs. When the upper arm of the arm support is down in any way, there will be
tension on the springs. When the arm support isn’t used, always bring the upper arm of the arm support
back into its most upwards position so that there is no tension on the springs.
•When getting the arm support out of a ‘parked’ position, make sure the arm is placed properly in the
brace and previously the compensation force has been set properly before you start moving the arm
support out of its parked position.
•Always be aware of the tension of the springs when the upper arm is in a downwards position.
•The arm support may only be used for the proposed purpose. Any type of use which is not specified in
this manual, will be considered as improper use. The customer is solely responsible for material damage
and injury of persons resulting from improper use; Armon Products will not be liable under any
circumstance.
•Assembly, commissioning and maintenance should only be carried out by trained specialists.
•In any circumstance, do not open the housing of the arm support. Warranty is void in such case.
•Do not use the arm support in environments exposed to corrosion hazards.
•Protect the arm support against sand, vapours and dust.
