NOTE: Before starting, read the warm and
cold starting procedures below.
6. Insert key into ignition and turn key
clockwise to start position and release
key as soon as engine starts. Do
not run starter continuously
for more
than fifteen seconds per minute. If the
engine does not start after several
attempts, push choke control in, wait
a few minutes and try again. If engine
still does not start, pull the choke con-
trol out and retry.
WARM WEATHER STARTING (50 ° F and
above)
7. When engine starts, slowly push choke
control in until the engine begins to
run smoothly. If the engine starts to
run roughly, pull the choke control out
slightly for a few seconds and then
continue to push the control in slowly.
• The attachments
and ground drive can
now be used. If the engine does not
accept the load, restart the engine and
allow it to warm up for one minute using
the choke as described above.
COLD WEATHER STARTING (50 ° F and
below)
7. When engine starts, slowly push choke
control in until the engine begins to run
smoothly. Continue to push the choke
control in small steps allowing the en-
gine to accept small changes in speed
and load, until the choke control is fully
in. If the engine starts to run roughly,
pull the choke control out slightly for a
few seconds and then continue to push
the control in slowly. This may require
an engine warm-up period from several
seconds to several minutes, depending
on the temperature.
AUTOMATIC TRANSMISSION
WARM UP
Before driving the unit in cold weather,
the transmission
should be warmed up as
follows:
1. Be sure the tractor is on level ground.
2. Release the parking brake and let the
brake slowly return to operating posi-
tion.
3. Allow one minute for transmission
to
warm up. This can be done during the
engine warm up period.
• The attachments
can be used during
the engine warm-up period after the
transmission
has been warmed up and
may require the choke control be pulled
out slightly.
NOTE: If at a high altitude (above 3000
feet) or in cold temperatures
(below 32 F)
the carburetor fuel mixture may need to
be adjusted for best engine performance
(see "TO ADJUST CARBURETOR"
in the
Service and Adjustments
section of this
manual).
PURGE
TRANSMISSION
A(_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 will 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).
7. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to half (1/2) speed.
Disengage parking brake.
8. Drive tractor forward for approximately
five feet then backwards for five feet.
Repeat this driving procedure three
times.
Your transmission
is now purged and now
ready for normal operation.
