Shifting
This model has a 5-speed forward and 1-speed re-
verse transmission with centrifugal automatic
clutch. The transmission allows you to control the
amount of power you have available at a given
speed or for starting accelerating, climbing, etc. To
shift into neutral, return the throttle lever to its orig-
inal position and repeatedly depress the shift ped-
al until it stops.CAUTION:
Do not coast for long periods with the engine
off, and do not tow the machine a long dis-
tance. Even with gears in neutral, the transmis-
sion is only properly lubricated when the
engine is running. Inadequate lubrication may
damage the transmission.
