6.2.2 Adjusting the drive wheels vertically
The vertical position of the drive wheels can be changed by vertically moving the quick-release axle receiver bush­
ing in the drive wheel adapter.
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
• 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.
With the help of the quick-release axle receiver bushing (quick-release axle mounting), the drive wheel can be
installed at 6 height positions in the drive wheel adapter (see fig. 2, item 1; see fig. 36, item 1–6).
1) Remove the wheels.
2) Loosen and remove the hexagon nut (see fig. 3, item 1) from the quick-release axle mounting (see fig. 3,
item 2) on the inside of the drive wheel adapter.
3) Remove the Nord-Lock washer (see fig. 3, item 3)
4) Remove the quick-release axle mounting together with the remaining hexagon nut and insert it into the drive
wheel adapter in the desired position.
5) Slide on the Nord-Lock washer (see fig. 3, item 3) and firmly retighten the hexagon nut (see fig. 3, item 1).
6)
If necessary:
The horizontal distance between the drive wheel and side panel can be adapted by adjusting the
quick-release axle mounting. To do so, the distance is continuously adjustable with the help of the counter nut
(not illustrated).
7) Tighten the hexagon nut and counter nut on both sides of the quick-release axle mounting to 50 Nm (see fig. 3,
item 1).
INFORMATION: Once changed, the left and right quick-release axle mountings must both have the
same vertical position in the frame.
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).
