►Use an anti-tipper for inexperienced users and with extreme settings of the drive wheel.
►Be sure to position the drive wheels towards the rear for transfemoral amputees. This improves the stability of
the wheelchair.
INFORMATION
Changing the drive wheel position can also change the angle between the caster wheel journal and the ground.
However, this must always be approx. 90° and thus readjusted accordingly. The knee lever wheel lock also has
to be readjusted.
7.3.1 Setting the drive wheels horizontally
The horizontal position of the drive wheels is adjusted by moving the fitting horizontally in the drive wheel adapter.
Changing the drive wheel position has the following effects:
Position of drive wheel Effects
Move backwards (passive setting) • Larger wheelbase
• Larger turning circle
• Greater stability of the wheelchair
• Wheelchair is harder to tip backwards when crossing obstacles
• Position recommended for inexperienced users
Move forwards (active setting) • Smaller wheelbase
• Less load on caster wheels = greater manoeuvrability
• Less stability of the wheelchair
• Wheelchair is easier to tip backwards when crossing obstacles
INFORMATION: An anti-tipper should be installed if necessary.
• Setting recommended only for experienced users
The drive wheel can be installed at 4 depth positions in the drive wheel adapter.
1) Remove the wheels.
2) Loosen the hexagon nut (see fig.7, item1) from the fitting and remove the fitting towards the inside.
3) Slide the fitting back on in the desired position and tighten the hexagon nut slightly.
4) Check the toe-in and adjust as needed (see Page20).
5) If necessary: The distance between the drive wheel and the side panel can be continuously adjusted by turn
ing the counter nut on the fitting.
6) Tighten the hexagon nut (see fig.7) and the counter nut on both sides of the fitting to 50Nm.
INFORMATION: After adjustment, the distance of the left and right fittings to the side panel must be
the same.
7) Check the depth setting. Both sides must be positioned exactly the same. Readjust if required.
8) If necessary: Readjust the height and alignment of the caster attachment device as well as the wheel locks
(see information at the start of the section).
7.3.2 Adjusting the drive wheels vertically
The vertical position of the drive wheels can be changed by vertically moving the drive wheel adapter in the frame.
Combined with adjusting the height of the caster wheels, this also allows the seat height to be optimally adjusted to
individual requirements.
Changing the drive wheel position has the following effects:
Drive wheel position Effects
Move upwards • The higher the drive wheel position, the more the seat surface is tilted to
the rear
• Wheelchair is easier to tip backwards when crossing obstacles

Drive wheel position Effects
• The change in the centre of gravity results in a lower, more stable seat
position in the wheelchair
• The seat height can be further adjusted in combination with a height
adjustment of the caster wheels.
Move downwards • The lower the drive wheel position, the less the seat surface is tilted to the
rear
• Wheelchair is harder to tip backwards when crossing obstacles
• The seat height can be further adjusted in combination with a height
adjustment of the caster wheels.
The drive wheel can be installed at 4 height positions.
1) Remove the wheels.
2) Remove the Allen head screws/counter nuts (see fig.8).
3) Push the drive wheel adapter to the desired position.
4) If necessary: Additional drive wheel positions can be obtained by turning the drive wheel adapter by 180°.
→In this case, the fitting also has to be installed again (see previous section).
→The toe-in has to be readjusted as well (see Page20).
5) Insert and tighten the Allen head screws/counter nuts to 8Nm (see fig.8).
6) Only after rotating the drive wheel adapter: Tighten the screw connection on the fitting to 50Nm.
→Once changed, the left and right drive wheel adapters must both have the same vertical position in the frame.

7.3.3 Adjusting the drive wheel camber
The modular system of the product offers camber washers for different sloped settings of the drive wheels.
The drive wheel camber is adjusted by exchanging the camber washers in the fitting (quick-release axle mounting).
This has the following effects:
Position of drive wheel Effects
0° position • Narrow track, excellent straight-line stability
• Low rolling resistance
Wheel camber • Wheelchair becomes more manoeuvrable, turns faster and tips less easily
to the side
• The wheel position protects the hands when turning the handrim
• Overall width increases
• Increased rolling resistance
The drive wheel camber can be set to 0° or 2.5° (1° or 3.5° with drive wheel attachment device for 3.5° wheel cam
ber).
The settings can be configured with a corresponding alignment of the camber washers:

INFORMATION
►Please be aware that with a larger negative camber the overall width of the wheelchair increases and the drive
wheels are subjected to higher stress.
Adjusting the drive wheel camber
1) Remove the wheels.
2) Loosen the hexagon nut on the inside from the fitting (see fig.11, item1) and remove the fitting to the outside.
3) Slide the camber washers onto the quick-release axle receiver bushing according to the table and align them.
4) Slide the fitting back on and tighten the hexagon nut slightly (see fig.11, item1). Readjust the toe-in before
tightening (see Page20).
5) If necessary: The distance between the drive wheel and the side panel can be continuously adjusted by turn
ing the counter nut.
6) Tighten the hexagon nut and the counter nut on both sides of the fitting to 50Nm.
INFORMATION: After adjustment, the camber of the left and right drive wheels must have the same
angle.
7) If necessary: Readjust the height and alignment of the caster attachment device as well as the wheel locks
(see information at the start of the section).
