SAFETY INFORMATION

1Gasoline and exhaust gas


GASOLINE IS HIGHLY FLAMMA-
BLE:
Be sure to always use a fresh
mixture of oil and gasoline.
Always turn the engine off when
refueling.
Take care not to spill any gaso-
line on the engine or exhaust
pipe/muffler 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
motorcycle in an area that has ad-
equate ventilation.


Always turn the engine off before
leaving the motorcycle unattend-
ed. When parking the motorcycle,
note the following:
The engine and exhaust
pipe/muffler may be hot, there-
fore, park the motorcycle in aplace where pedestrians or chil-
dren are not likely to touch these
hot areas.
Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.
Do not park the motorcycle near
a flammable source (e.g., a ker-
osene heater, or near an open
flame), otherwise it could catch
fire.


When transporting the motorcycle
in another vehicle, make sure that
it is kept upright and that the fuel
cock is turned to “OFF”. If the
motorcycle should lean over, gas-
oline may leak out of the carbure-
tor or fuel tank.


If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately.
If any gasoline spills on your skin
or clothing, immediately wash the
affected area with soap and water
and change your clothes.
