used. The throttle should be opened slightly.
EBU01820
Warming up

EBU01981
Shifting
This model has a 5-speed forward transmission.
The transmission allows you to control the amount
of power you have available at a given speed or for
starting, accelerating, climbing hills, etc. To shift
into neutral, return the throttle lever to its original
position, apply the clutch and repeatedly depress
the shift pedal until it stops. When it stops, it will be
in first gear. Raise the pedal slightly to neutral.CAUTION:_

Do not coast for long periods with the en-
gine off, and do not tow the machine a long
distance. Even in neutral position, the
transmission is only properly lubricated
when the engine is running. Inadequate lu-
brication may cause damage.


Always use the clutch when changing
gears. The engine, transmission and drive
train are not designed to withstand the
shock of forced shifting and can be dam-
aged by shifting without the clutch.
