from the factory, already filled with summer
weight oil.
1. Check engine
oil with tractor
on level
ground.
2. Remove
oil fill cap/dipstick
and wipe
clean, reinsertthe
dipstick and screwcap
tight, wait for a few seconds,
remove and
read oil level.
If necessary,
add oil until
"FULE' mark on dipstick
is reached.
Do
not overfill.
° For cold weather
operation
you should
change oil for easier starting
(See the oil
viscosity
chart in the Maintenance
section
of this manual).
• To change engine oit, see the Maintenance

in this manual.
ADD GASOLINE
.......
- Fill fuel tank to bottom
of filler neck, Do
not overfill,
Use fresh,
clean,
regular
unleaded
gasoline
with
a minimum
of
87 octane.
(Use of leaded gasoline
will
increase
carbon and lead oxide deposits
and reduce valve life). Do not mix oil with
gasoline,
Purchase
fuel in quantities
that
can be used within 30 days to assure fuel
freshness,
_CAUTION:
Wipe offany spilled oil or fuel.
Do not store, spill or use gasoline
near an
open flame.
IMPORTANT:
when
operating
in tempera-
tures
below
32°F(0°0),
use fresh,
clean
winter grade gasoline
to help insure good
cold weather starting,
CAUTION:
Alcohol
blended
fuels
(called
gasohol
or using ethanol
or methanol)
can
attract
moisture
which leads to separation
and formation of acids during storage.
Acidic
gas can damage thefuelsystemofan
engine
while in storage,
To avoid engine problems,
the fuel system
shouid
be emptied
before
storage
of 30 days or longer.
Drain the gas
tank, start the engine and let it run until the
fuel lines and carburetor
are empty.
Use
fresh fuel next season.
See Storage instruc-
tions for additional
information.
Never use
engine or carburetor
cleaner products in the
fuel tank or permanent
damage
may occur,
TO START
ENGINE
When starting the engine for the first time or
if the engine has run out of fuel, it will take
extra cranking
time to move fuel from the
tank to the engine,
1. Be sure freewheel
control is in the trans-
mission engaged
position.
2. Sit on seat inoperating position, depress
brake pedal and set parking brake.
3. Move attachment clutch to disengaged
position,
4. Move throttle control to choke position.
NOTE: Before starting, read the warm and
cold starting procedures below,
5. 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, move
throttle control to fast position, wait a
few minutes and try again, If engine still
does not start, move the throttle control
back to the choke position and retry.
WARM WEATHER STARTING (50°F/10 °
C and above)
6, When engine starts, move the throttle
control to the fast position.
• The attachments and ground drive can
now be used. Ifthe 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/10 ° C
and below)
6. When engine starts, leavethrottle control
in choke position until engine warms up
and begins to run roughly. Once rough
running begins, immediately move the
throttle control to the fast position. Engine
warm-up may take from several seconds
to several minutes (the colder the tem-
perature, the longer the warm-up).
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weather, the
transmission should be warmed up as fol-
lows:
1. Be sure the tractor is on level ground.
2. Release the parking brake and let the
brake slowly return to operating position.
3. AIIow one minutefortransmissionto
warm up. This can be done during the
engine warm up period.
• The attachments can also be used dur-
ing the engine warm-up period after the
transmission has been warmed up.
NOTE: ffata high altitude (above 3000 feet)
or in cold temperatures (below 32°F/0°C)
the carburetor fuel mixture may need to be
adjusted for best engine performance (see
"TO ADJUST CARBUR ETOR" inthe Service
and Adjustments section of this manual).
