Shifting
This model has a 5-speed forward and 1-speed re-
verse 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 the closed 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.
