Place the groove pin into the motor axle recess (1).
Pull the wheel over the motor axle (1) to the stopping point (avoid poor alignment). In doing
this, ensure that the recess on the rim hub fits over the groove pin (2).
Hand-tighten the washer and screw (thread locker can be used to secure it).
Before you can remove a tyre, you must let all the air out of the tube, and insert a tyre lever between
the tyre and the rim. Then slowly and carefully push the lever downwards. This will pull the tyre over
the edge of the rim. If you then move the lever along the rim, the tyre will jump out. Now carefully
remove the tyre from the rim and then remove the tube.
L There must be no air in the tube before it can be removed.
L If handled improperly, the rim might be damaged. These procedures should only be
undertaken by authorised individuals.
Note the following before inserting the new inner tube:
Check the rim bed and the inside wall of the tyre for foreign matter and clean these properly if
necessary. Check the condition of the rim bed, especially around the position of the air valve. Please
use only genuine original replacement parts. We do not accept any liability for damage caused by non-
genuine parts. Kindly contact your specialist dealer.
Assembly:
Place the rim belt in position over the air valve before inserting it into
the rim. Then the rim belt can be pulled over easily. Check whether
all spoke heads are covered (in the case of a plastic rim a rim belt is
not required).
Push the tyre over the edge of the rim, starting behind the air valve.
Inflate the tube slightly until it is round, and place it inside the tyre.
If the inner tube fits snugly inside the tyre without any folds (if there
are folds, let some air out), then you can push the upper side of the
tyre gently onto the rim with both hands, beginning behind the
airvalve.
Check all around on both sides that the tube is not pinched between the rim and the edge of the tyre.
Lightly push the air valve inwards and pull it out again to make sure that the tyre is positioned properly
in the region of the air valve.
To ensure that the wheel is inflated correctly, admit only so much air initially that the tyre can still be
easily pushed inwards by using your thumbs. If the check-lines are equidistant from the edge of the
