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 castor wheel will start to wobble at high speeds.
