environment. The exhaust fumes are
poisonous which may cause loss of
consciousness and death within a
short time. Operate the motorcycle
always with adequate ventilation.

been back to its original position be-
fore riding; otherwise, serious acci-
dent may occur when turning.
3.After warming the engine, hold the
fixed bracket by right hand and push
the motorcycle off the center-stand.
4.Sit astride the seat and adjust the
rear view mirrors.
5.Check the oncoming traffic; switch
on the turn signal before starting off.

handlebar slowly to take off, switchoff the turn signal.■ ■■ ■
■Shut-down the engine and
park the motorcycleWhen stopping, turn the main switch
to position OFF.
WARNING

Since the exhaust pipe of muffle
may become extremely hot, you
should park the motorcycle in a
place where pedestrians or children
are unlikely to come in contact with
the vehicle. Do not park on a slope
or soft ground, otherwise the mo-torcycle may overturn.

OPERATION AND IMPORTANT RIDING POINTS■ ■■ ■
■Engine exhaustWe take the environmental protection
into consideration maturely, our mo-
torcycles are equipped with AIS sys-
tem and agent catalyzing device in the
exhaust pipe, and can meet the re-
quirement of Europe II emission
standard.
Massive incomplete combusted gas
mixture will re-combust when flowing
into the hot agent catalyzing device,
thus causes exhaust pipe overheat-
ing and shortens the service life of
catalyzing device. To prevent this kind
of situation and other damages,
please read the following list carefully.
CAUTION:

. Only use unleaded fuels (#93 un-
leaded petrol). The leaded petrol will
cause the catalyzing device be-
come contaminated and rendered
useless.. When riding, do not turn off the
main switch. Otherwise, it will pro-
duce massive incomplete com-
busted gases.. If the ignition or fuel system is
out of condition, the agent cata-
lyzing device will overheat.. Be careful when the motorcycle
rides for a period of time, the out-
side of exhaust pipe will be very hot.. Do not splash or overfill the fuel
to the exhaust pipe when re-fueling.
It may burn when the petrol drippedto hot exhaust pipe.
