* Regularly check that the various screwed parts are tight,
particularly the wheel axles, the collapsible axis, the brake
shaft, and the head tube locking collar and suspension,
because the self-tightening screws or other attachment may
lose their effectiveness.
* Always replace used parts with original parts.
* Keep the scooter in a dry, dust-free place.
* Do not modify or transform the scooter, specifically the
steering column and socket, the stem, the folding mechanism
and the brake.
