Function check
Tip the wheelchair backwards by 90° so that it is lying on the backrest
and the rear wheels. Make sure that the clevis pin is as horizontal as
possible. Turn the fork upwards (position A) and let it tip downwards.
The fork has been correctly adjusted if it easily turns to slightly
beyond the bottommost point (position B) and then maximally turns
back to the bottommost point (position C).
If the fork turns back over the bottommost point or even swings back
and forth, it has not been sufficiently tightened. There is a risk that the
front wheels will start to wobble at high speeds.
