Further safe-riding points
•Be sure to signal clearly when making turns.
•Braking can be extremely difficult on a wet road. Avoid hard braking, because the scooter could slide.
Apply the brakes slowly when stopping on a wet surface.
•Slow down as you approach a corner or turn. Once you have completed a turn, accelerate slowly.
•Be careful when passing parked cars. A driver might not see you and open a door in your path.
•Railroad crossings, streetcar rails, iron plates on road construction sites, and manhole covers become
extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright, otherwise
it could slide out from under you.
•The brake pads could get wet when you wash the scooter. After washing the scooter, check the brakes
before riding.
•Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they do not flap), and a
bright colored jacket.
•Do not carry too much luggage on the scooter. An overloaded scooter is unstable.

The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
