1.3 Description of the wheelchair
The wheelchair consists of a rigid frame onto which the seat
module and the foldable backrest are attached.Both the
left and the right side frame are attached to an axle tube . The
rear wheels are mounted to the frame with rear wheel fixture
elements.The front wheels as well as the footrest are fixed
to the front frame.(See figure 1)
1.4 Use as per specifications
The wheelchair is driven manually and is used for independent
or guided locomotion of gait-impaired persons (e.g.hemiplegia,
paraplegia, tetraplegia, multiple sclerosis, traumatic brain injury,
etc.).The wheelchair may only be used without a guide by
persons who are physically competent to handle the wheelchair
(eg.driving,steering and braking).The wheelchair is designed
for in- and outdoor use on level ground and pathed terrain.
1.5 Before using the wheelchair
Before using the wheelchair for the first time, please read
Chapter 2 - Using the wheelchair carefully and follow the
safety instructions.
It is essential that you check the functionality of your wheelchair
daily.Pay special attention on the following parts (provided they
are mounted):Wheels, backrest, antitipper, pushhandles, quick
release fork.
Normally, your authorized dealer will unpack and unfold the
wheelchair if necessary for you.If you receive your wheelchair
unfolded, please read Chapter 3.1 - Folding and unfolding the
wheelchair.

2Using the wheelchair
2.1 Sitting down / getting up
When getting in or out of the wheelchair, do not stand on
the footrests. Danger of tipping!
You should only get on/off the wheelchair if you are
physically competant. Please consult your physician or
therapist.
Do not sit on the clothing guard, the tire cover or the
armrest when getting on/off the wheelchair. They might
bend or break. Danger of injury!
The method you use to transfer in and out of your wheelchair
will depend on your own capabilities. Generally, the procedure is
as follows:
Pull the parking brake
Hold on to the wheelchair and, if necessary, to a stable object
nearby.
2.2 Driving and steering the wheelchair
Finding the tipping point
The tipping point of the wheelchair depends on the adjustment
of the seat position.The correct seat position is adjusted
depending on parameters such as the weight of the user, the
type of handicap and the driver's driving skills.The seat position
which is adjusted upon delivery corresponds to the information
indicated in your order.
Figure 2
To find the tipping point of your wheelchair, proceed as follows
(see Figure 2):
When determining the tipping point, an aide must always
stand directly behind the wheelchair in order to catch it in
case it tips.
To ensure that you are in control of your wheelchair at
any given point, you should not exceed a speed of 7km/h.
(4Mph)

Loosen the brakes
Sitting in the wheelchair, move forwards briefly, hold both
hand rims tightly and pull back with a slight swing.
By shifting your weight slightly and applying a counter-force
to the hand rims,the tipping point can be determined.

0R33 5
To avoid the wheelchair tipping backward, we recommend that
the wheelchair should be equipped with an antitipper (see
Chapter 4).
Please note that a heavy backpack fixed to the backrest can
affect the tipping behaviour of the wheelchair.
The position of the seat module influences the balance and the
tipping tendency of the wheelchair. The centre of gravity must be
re-defined after adjustments have been made.
2.3 Driving over stairs and steps
Always be very careful and move slowly when driving
over curbstones, stairs or other steps.
Do not try to drive over steps which have a height of more
than 25 cm.
Only drive on stairs with more than one step if an aide is
behind the wheelchair.
With an aide
Figure 3
Driving down a step
Drive to the edge of the step,make sure that the wheelchair
is in a straight position.
Hold on to the two push handles on the rear of the
wheelchair and tilt backward so that the front wheels leave
the ground.
Hold the wheelchair in this position and push it down the
step slowly.The wheelchair driver can support you by using
the hand rims.

6 0R33
Tilt the wheelchair forward until the front wheels have
ground contact again.
Driving up a step
Do not lift the wheelchair by the backrest bar.
Move the wheelchair backward until the rear wheels hit the
edge of the step.
Pull back both push handles, tilt the wheelchair until the
front wheels leave the ground and pull the rear wheels over
the edge.
Move the wheelchair until you can safely tilt the wheelchair
forward and the front wheels have ground contact again.
Without an aide
If you want to drive down a step without a guide, you
must have perfect control over your wheelchair and must
be able to balance it on the rear wheels. (see Finding the
Tipping Point in Chapter2.2).
Figure 4
Driving down a step
Drive to the edge of the step,make sure that the wheelchair
is in a straight position.
Lift up the front wheels from the floor by shifting your body
weight and keep your balance.
Now let the two rear wheels roll down over the edge.Make
sure to hold the hand rims tightly.
Tilt forward the wheelchair until the front wheels have
ground contact again.
Driving up a step
Drive the wheelchair backward until the rear wheels hit the
edge of the step.

0R33 7
Lift up the front wheels from the floor by shifting your body
weight and keep your balance.
Now let the two rear wheels roll up over the edge. Make sure
to hold the hand rims tight.
Move the wheelchair until you can tilt the wheelchair
forward safely.
Lower the front wheels again.
2.4 Driving on ramps and slopes
Only drive on long slopes if a guide is behind the
wheelchair.
Do not drive on steep or lateral slopes (max. assending
grade 7°). Danger of tipping!
Avoid abrupt changes of direction when driving on
slopes. Danger of tipping!
Never pull the parking brakes when the wheelchair is in
motion. Danger of tipping!
Driving uphill
To drive uphill you must set the wheelchair in motion and
maintain the motion in order to be able to control the direction.
Figure 5
Lean forward and drive the wheelchair by pushing the hand
rims quickly and powerfully.
Downhill
When driving downhill direction and, above all, speed must be
controlled.

Figure 6
Lean back and let the hand rims slip through your hands
carefully.You should be able to stop the wheelchair at any
time by holding the hand rims.
Please note that, the hand rims can heat if you brake for longer
periods of time by hand. This applies especially to MaxGrepp
and Supergripp handrims
2.5 Stability and balance when sitting in the
chair
For many every day life activities you will have to bend out of
the wheelchair, forwards,to the side or backwards.This has a
great influence on the stability of the wheelchair. In order to
keep your balance at any time,please observe the following:
Leaning forward
Figure 7
Align the front wheels to the front. (To do this, move the
wheelchair slightly forward and then back again.)
Apply both parking brakes.
When leaning forward, make sure that your abdomen
remains above the front wheels.
Do not lean forward too much. You might fall out of the
wheelchair!
Do not slide forward in your seat to reach out for remote
objects. You might fall out of the wheelchair!
Do not try to bend your abdomen forward between your
legs in order to pick up something from the floor.

0R33 9
Leaning backward
Figure 8
Align the front wheels to the front. (To do this, move the
wheelchair forward a bit and then back again.)
Do not apply the parking brakes.
Reach out backward only as much as possible without
leaving your sitting position.
Do not lean over the backrest. You might tip backward.
2.6 Parking brakes
If your wheelchair is not equipped with a drum brake,
deceleration is effected manually by applying force on the hand
rims of the rear wheels.The parking brakes are used only for
keeping the wheelchair in place when standing and to prevent
it from rolling away.The correct function of the parking brakes is
ensured only if sufficient air is in the tire.(see Chapter 5.2 -
Maintenance)
Never apply the parking brakes when the wheelchair is in
motion - Danger of tipping!
For adjusting the parking brakes please see chapter 4.
