1.0 SAFETY GUIDELINES
WARNING! An authorized Provider or qualified technician must perform the initial
setup of this wheelchair and must perform all of the procedures in this manual.
The symbols below are used throughout this owner's manual to identify warnings and important
information. It is very important for you to read them and understand them completely.
WARNING! Indicates a hazardous situation that could result in serious injury or death if
it is not avoided.
CAUTION! Indicates a hazardous situation that could result in minor or slight injury if it
is not avoided.
! IMPORTANT! Indicates a hazardous situation that could result in damage to property if it is
not avoided.
іUSEFUL TIP! Recommendations and information for efficient, trouble-free use.
Your wheelchair is a state-of-the-art life-enhancement device designed to increase mobility. We
provide an extensive variety of products to best fit the individual needs of the user. Please be aware
that the final selection and purchasing decision regarding the type of product to be used is the
responsibility of the user who is capable of making such a decision and his/her health care professional
(i.e., medical doctor, physical therapist, etc.).
The contents of this manual are based on the expectation that a mobility device expert has properly
fitted the wheelchair to the user and has assisted the prescribing health care professional and/or the
authorized provider in the instruction process for the use of the product.
There are certain situations, including some medical conditions, where the user will need to practice
operating the wheelchair in the presence of a trained attendant. A trained attendant can be defined as
a family member or care professional specially trained in assisting a wheelchair user in various daily
living activities.
As you begin using your wheelchair during daily activities you will probably encounter situations in
which you will need some practice. Simply take your time and you will soon be in full and confident
control.

6.0 OPERATION –OPERATING YOUR WHEELCHAIR
You will have to learn the characteristics of your wheelchair. It is most important to learn
the safest methods to develop the daily activities in accordance to your life style. Consult your
medical advisor or therapist for assistance by developing safe and effective techniques for your
daily activities and your physical possibilities.
Daily operations such as getting off the wheelchair, reaching and bending in the
wheelchair will cause a change of weight distribution and a change in the in the center of gravity
of you and your wheelchair.
6.1 TRANSFERRING –GETTING OUT OF WHEELCHAIR
Transferring in a wheelchair is a difficult manoeuvre. Consult your physical therapist for
assistance in developing your individual technique. The possibilities you have for making a
transfer are depending on your physical characteristics. We advise you to discuss this first with
your physical therapist. However if you have sufficient body strength and you want to transfer to
and from the wheelchair you will best do this in the following manner:
1. First of all you must make sure that your wheelchair stands as closely as possible to the
place of where you wish to transfer to.
2. Put the castors forward and engage the wheel hand brakes. Swing away the footplates
and place your feet on the ground.
3. You are now in position to carry out the operation. Shift your weight to the front of the
chair, you can use the armrests as a support and move yourself to the place where you wish to
transfer to. If necessary you can use a transfer board.
6.2 TRANSFERRING –GETTING INTO THE WHEELCHAIR
1. To get into your wheelchair you need to do the same things as when you want to get out
of the wheelchair, only in the reversed order.
CAUTION! Reaching: We strongly recommend that you seek the help of an attendant to
pick something up for you.
WARNING! Always use the Wheel Hand Brake when transferring to and from the
wheelchair.

8
6.3 CURBS AND PAVEMENTS
When going up a curb the attendant can help you in two different ways, however we advised you
to do it the first way.
1. METHEOD ONE for going up a pavement you and the attendant reach the pavement
facing forward. The attendant must pull the push handles and place his foot on the foot
tipper (Fig 6.3.1).
Fig 6.3.1
2. METHEOD TWO for going up a pavement the attendant is already standing on the
pavement and makes sure that the wheelchair is positioned with the rear wheels as close to
the pavement as possible. The user of the wheelchair needs to lean backwards. This way the
wheelchair will tip backwards and the attendant can pull the chair on the pavement. The
attendant needs to make sure that the front wheels are on the pavement before he lets the
wheelchair down.
GOING DOWN THE PAVEMENT: The attendant should move the wheelchair forward to
the curb. Then the user should lean back so the attendant can tilt the wheelchair to find a
balance point. When the wheelchair is balanced the attendant can move the wheelchair slowly
off the curb. When the wheelchair is off the pavement, the attendant can let the front wheels
back onto the ground.
WARNING! Never drive into curbs
6.4 RAMPS AND SLOPES
Before manouvering on a ramp or slope, inspect for risks such as holes or slippery and eneven
surfaces.
Before manouvering on a ramp or slope, make sure that there is adequate clearance from the
ground to footrest (at least 7cm) to prevent footplate catching on the slope.
WARNING! Never carry any weight on the back of the wheelchair whilst ascending. This
changes the balance and increases the chances of tipping backwards.

9
6.5 STAIRS
Stairs are one of the largest obstacles for wheelchair users. However, with a little help
from two attendants it is possible to climb up and down the stairs. Assessment of the weight
that has to be moved should be undertaken by the attendants prior to this manoeuvre.
To go upstairs you need to go up the stairs backwards. One attendant at the front and one
attendant at the back. The attendant at the back holds the push handles and lets the wheelchair
tip backwards until it is in balance. When the wheels are in balance the attendant at the front
needs to hold the side frames. You are now in position to climb the stairs. The attendant on the
front pushes the side frames up until they are above the first step and the attendant at the back
makes the first step on the stairs. Repeat this technique until the last step of the stair. You can
let the front castors down when the attendant at the front has taken the last step.
To go downstairs, the wheelchair should be facing forwards. The rear attendant should tip
the wheelchair until it balances. The front attendant should support the wheelchair by holding
the side frames. The wheelchair should then be slowly guided down each step.
WARNING! Never lift the wheelchair by the push handles, armrests or footrests. Always
hold a part of the main frame.
7.0 OPERATION –FOLDING & UNFOLDING
7.1 UNFOLDING WHEELCHAIR

11.0 MAINTENANCE & DAILY CHECKING
Protect your wheelchair by having it checked regularly. We strongly advise you to have
your wheelchair check at least once a year by a qualified dealer, who will only use the
correct spare parts. This periodic inspection will ensure you that the wheelchair will
function perfectly for years. There are a lot of things you can do yourself to keep your
wheelchair in optimum condition. If you regularly check the wheelchair and perform (small)
maintenance, this will extend the lifetime and increase the ease of use.
11.1 TYRES AND WHEELS
Examine tyres periodically for wear and replace them as needed.
Make sure the wheels can move freely without touching anything.
The front wheel and fork should move freely to ensure a smooth ride.

them. Ensure that all the parts of the brake are in the right position and fastened securely.
11.3 CROSS FRAME
Check that the cross frame of the wheelchair is in good condition. Make sure the wheelchair
is easy to fold and un-fold.

Check the upholstery-mounting grommets to make sure that they are all correctly aligned
and secure.
11.5 CLEANING
Clean the upholstery, chassis and plastic components on the wheelchair regularly with a
mild soap and water. Never use abrasive cleaners, they can damage the varnish. Also never
use steam or high pressure cleaners.
Wax the varnish of the chassis regularly. Never use solvents, abrasive waxes, caustic
chemicals or spray silicone.
Dry your wheelchair after cleaning. Also dry your wheelchair after you have been using it
in the rain.
