Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics of
your scooter, you should keep the
following precautions in mind.•
NEVER OVERLOAD THE SCOO-
TER! Operation of an overloaded
scooter may result in tire damage,
loss of control, or severe injury.
Make sure that the total weight of
rider, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
•
Do not carry along loosely packed
items, which can shift during a
ride.
•
Securely pack the heaviest items
close to the center of the scooter
and distribute the weight evenly
on both sides.
•
Adjust the suspension and tire air
pressure with regard to the load.
Check the tire condition and airpressure before each ride.
