Thetyresarexedtothewheelrimtopreventthemfromcomingloose.Whenthetyreisworndown,theentirewheel
has to be replaced therefore.
After loosening of the wheel nut (A), the wheel may be
removedfromthewheelaxle(C).
Thenthenewwheelispluggedonsothatthehexagon
socket on the wheel rim's inside is precisely pushed onto
the wheel tappet nut (B).
Screwthewheelontothewheelaxlewiththewheelnut
(A)removedatrst.However,donotapplyanyforcefor
screwing on. This will require greater force to turn the
wheel, which may damage the drive.
The wheel tappet nut (B) may remain in the rim when re-
movingtherearwheelordetachfromthewheelaxle(C)
when the wheel is taken off. In this case ensure that the
tappet pin (D) does not fall out and get lost.
When the wheel is later replaced, ensure that the tappet
pin(D)isexactlyinthecentreofthewheelaxle(C)and
inserted into the respective groove of the wheel tappet nut
(B).
If the tappet pin (D) is missing, no torque can be trans-
ferred from the motor to the wheel and the wheel will spin
freely.
