SAFETY INFORMATION
1-5
1


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 cor-
ner or turn. Once you have com-
pleted 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 be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the scooter up-
right, otherwise it could slide out
from under you.


The brake pads and linings could
get wet when you wash the scoot-
er. 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 scoot-
er is unstable. Use a strong cord to
secure any luggage to the carriers.
A loose load will affect the stability
of the scooter and could divert
your attention from the road. (See
page 1-1.)

tle grip in direction (b).

Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.


Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slowdown when approaching such
areas and cross them with cau-
tion.


Keep in mind that braking on a
wet road is much more difficult.


Ride slowly down a hill, as brak-
ing downhill can be very diffi-cult.
