c) Wheel change
Thetiresarexedontherim,sothattheycannotbedeta-
ched from the rim. When the tires are worn-out, the entire
wheel must be replaced.
After loosening the wheel nut (B), pull the wheel out of the
wheelaxle(D).
Thenthenewwheelisplacedsothatthehexkeycanget
insideoftherimexactlyonthewheelhubnut(A).
Fastenthewheelontothewheelaxlewiththewheelnut
(B)that was removed at the beginning. However, do not
useexcessiveforcewhentightening,otherwisethewheel
rotateswithdifculty,whichcandamagethedrive.
Check also the correct placing of the wheel nut (B) during
tightening. During tightening, the ridged side of the wheel
nut (see image above) must face toward the wheel (the
ridged area of the wheel nut serves as protection against
the accidental loosening of the nut).
Perhaps the wheel hub nut (A) remains stuck in the rim
when pulling off the rear wheel or it detaches from the
wheelaxle(D).Thenbesurethatthecarrierpin(C)does
not fall out and gets lost.
Later, when the wheel is placed back, it is important to
checkthatthecarrierpin(C)isinsertedexactlyinthecen-
treofthewheelaxle(D)andislocatedinthecorrespon-
ding groove in the wheel hub nut (A).
If the drive pin (C) is missing, no torque from the motor
to the wheel is transmitted and the wheel rotates freely.
