PURGE
TRANSMISSION
_CAUTION:
Never engage or dis-
engage freewheel lever while the engine
is running.
To ensure proper operation and per-
formance,
it is recommended
that the
transmission
be purged before operating
tractor for the first time. This procedure will
remove any trapped air inside the trans-
mission which may have developed during
shipping of your tractor.
IMPORTANT:
Should your transmission
require removal for service or replace-
ment, it should be purged after reinstall-
ation before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
2. Disengage transmission
by placing
freewheel control in disengaged posi-
tion (See "TO TRANSPORT"
in this
section of manual).
3. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to slow position. Disen-
gage parking brake.
4. Depress forward drive pedal to full
forward position and hold for five (5)
seconds and release pedal. Depress
reverse drive pedal to full reverse posi-
tion and hold for five (5) seconds and
release pedal. Repeat this procedure
three (3) times.
NOTE: During this step there wilt be no
movement of drive wheels. The air is being
removed from hydraulic drive system.
5. Shutoff engine and set parking brake.
6. Engage transmission
by placing free-
wheel control in engaged position (See
"TO TRANSPORT"
in this section of
manual).
