OPERATION AND IMPORTANT RIDING POINTS
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
When parking, stop the engine, remo-
ve the key from the main switch, and
then turn the fuel cock lever to "OFF".
Since the engine and exhaust
system can become very hot,
park in a place where pedes-
trians or children are not likely
to touch them.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.
Never park in an area where there
are fire hazards such as grass or
other flammable materials.
