The Scooter Malfunction
Changing the inner tube of the rear wheel
1. Make sure the scooter is disconnected from the charger and the display is off.
2. Place the scooter on a raised place (eg in a chair) so that the wheels are in the air and the
scooter is firmly held at the bottom of the foot.
3. Unscrew the two rear plastic covers.
4. Disconnect the motor cable connectors (on the right side).
5. Loosen the nuts on the motor axis. Remember (take a picture) the order and placement of the
washers on the motor axis.
6. Carefully remove the rear wheel incl. of the engine from the frame - the brake disc is
disengaged from the rear brake.
7. Loosen the six screws (1) connecting the rear rim and disconnect it.
8. Remove the defective tube (s) and replace it with a new one. Orient the tire according to the
wheel rotation arrow.
Before joining the rim, you can partially inflate the tube to prevent the tube from getting into the
rim joint.
9. Continue with the previous steps in reverse order. You can lay the frame on its side when
replacing the engine wheel. Fit the wheel so that the motor cable is facing the handlebar and
engage the rounded notch in the wheel axis.
10. Inflate the tire to 40-50 p.s.i. / 2.8-3.4 bar.
Changing the inner tube (tire) at the front wheel
1. Make sure the scooter is disconnected from the charger and the display is off.
2. Place the scooter on an elevated position so that the wheels are in the air and the scooter is
firmly held on the bottom of the tread.
3. Loosen the nuts on the motor axis. Remember (take a picture) the order and placement of the
washers on the motor axis.
4. Carefully remove the front wheel from the frame - the brake disc comes out of the front brake.
5. Remove the inner tube from the front rim and replace it with a new one. For easier removal of
the tire, you can brush the rim with liquid soap. When removing the tire, make sure that the rim,
shell and tube are not damaged - use only good quality mounting levers.
6. Continue with the previous steps in reverse order.
7. Inflate the tire to 40-50 p.s.i. / 2.8-3.4 bar.
