PURGE TRANSMISSION
_, CAUTION:
Never engage or disen-
gage freewheel
lever while the engine is
running.
To ensure proper operation and perfor-
mance, it is recommended
that the
transmission be purged before operating

remove any trapped air inside the
transmission which may have developed
during shipping of your tractor.
IMPORTANT:
Should your transmission
require removal for service or replacement,
it should be purged after reinstallation
before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
