Now test if the carrier is attached steady enough on the tow ball (and not easy to
twist). If not, you have to adjust the quick connector. Detach first
the carrier by sliding the plastic locking device to the right and
pull the handle up. Adjust the adjustment bolt (First release the
locking nut, than adjust the bolt and finally lock it again with the
locking nut).
Test again if the carrier is stable enough on the tow bal (and not
easy to twist). Repeat this until the carrier is completely stable.
Caution: Always make sure that the locking nut of the
adjustment bolt is tightened again!
When the bike carrier is not easy to
turn anymore, the quick connector
can be locked. Slide the plastic
locking devise to the left until the
green mark on the handle is 100%
visible. Lock the quick connector
with the key and take the key out
(the red mark is on the position of
the lock symbol). Keep it carefully on
a safe place. The bike carrier is now
also protected against theft.
Always check if the quick connector is well secured! The
green mark on the handle must be completely visible
and the red dot on the lock must be at the same position
as the lock symbol on the locking device.
The carrier now rests folded on the tow-bar.
