• Never refuel while smoking or
in the vicinity of an open flame.
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within
a short time. Always operate your
scooter in an area that has ade-
quate ventilation.
Always turn the engine off before
leaving the scooter unattended
and remove the key from the
main switch. When parking the
scooter, note the following:
• The engine and exhaust sys-
tem may be hot, therefore,
park the scooter in a place
where pedestrians or children
are not likely to touch these hot
areas.
• Do not park the scooter on a
slope or soft ground, otherwise
it may fall over.
• Do not park the scooter near a
flammable source (e.g., a kero-
sene heater, or near an open
flame), otherwise it could catch
fire.
If you should swallow any gasoli-
ne, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immedia-
tely. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your clot-
hes.
EAU10360
Further safe-riding points
Be sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard bra-
king, 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 cons-
truction sites, and manholecovers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep
the scooter upright, otherwise it
could slide out from under you.
The brake lining 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. 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.

tion.
