6.2.2.1 Adjusting the height of the drive wheels

The drive wheels can be moved vertically with the "long" slider in 15 height positions (see fig. 65) and with the
"medium" slider in 10 height positions (not pictured).
1) Remove the wheels.
2) Place the wheelchair upside down.
3) Loosen and remove the 2 Allen head screws on each clamping flange on the slider (see fig. 3, item 1; figure
with accessory mount).
4) Move the axle unit to the desired position on the slider (see fig. 4, item 2). Ensure the height settings are the
same.
5) Tighten the Allen head screws to 10 Nm (see fig. 3, item 1).
→ Once changed, the clamping flanges on the left and right must both have the same vertical position on the
slider.
INFORMATION
Following adjustment, the track of the drive wheel, the caster journal angle and the knee lever wheel lock must be
checked and, if necessary, readjusted (refer to the corresponding section).

6.2.2.2 Adjusting the height of the drive wheels in the shock absorber system

The drive wheels can be moved vertically with the "short" shock absorber system in 3 height positions (see fig. 69)
and with the "long" shock absorber system in 5 height positions (see fig. 70) (see fig. 5).
1) Remove the wheels.
2) Place the wheelchair upside down.
3) Loosen and remove the 2 x Allen head screws on each perforated plate from the clamping flange/spacer (see
fig. 6, item 1). Remove the axle assembly (see fig. 6, item 2).
4) Remove the spacers and place them in the required positions on the perforated plate (see fig. 7). Ensure the
height settings are the same.
Only if necessary: Turn the spacers (see fig. 8).
5) Hold the axle assembly with clamping flange to the perforated plates at the same height (see fig. 6, item 2).

Effects
• 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.
• 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.
