SAFETY INFORMATION

Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.

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 system
may be hot, therefore, park the
scooter in a place where pedes-
trians 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 gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediate-
ly. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.

Further safe-riding points

Be sure to signal clearly when
making turns.
Left turn
Right turn

Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the scooter could slide.

SAFETY INFORMATION

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 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 scoot-
er is unstable.
