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 6 depth positions in the drive wheel adapter (see fig.36, itemA–F).
1) Remove the wheels.
