BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL (See Fig_,12)
=
The engine in your tractor has been shipped, from the
factory, already filled with summer weight oil
Check engine oil with tractor on level ground.
°
Remove oil fill cap/dipstick and wipe clean, reinsert the
dipstick and push it all the way down into the tube, wait
for a few seconds, remove and read oil level.
If
necessary, add oil until "FULL" mark on dipstick is
reached_ Do not overfill.
°
For cold weather operation you should change oil for
easier starting (See OIL VISCOSITY CHART" in the
Customer Responsibilities section of this manual).

ADD GASOLINE
°
Fill fuel tank.
Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane. (Use of leaded
,gasoline witt 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.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
WARNING:
Experience indicates that 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 the fuel
system of an engine while in storage.
To avoid engine
problems, the fuel system should be emptied before stor-
age 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 (See Fig. 8)
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.
=
Depress clutch/brake pedal and set parking brake_
°
Place motion control lever in neutral (N) position_
°
Move attachment clutch to "DISENGAGED" position°
Move throttle control to choke (N)
position
Note:
Before starting, read the warm and cold starting
procedures below.
°
Insert keyinto ignition and turn keyclockwiseto"START"
position and release key as soon as engine starts. Do
not run starter continuously for more than fifteen sec-
onds 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 (N) position and retry.
WARM WEATHER STARTING (50° F and above)
°
When engine starts, move the throttle control to the fast
(,_) position.
°
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)
°
When engine starts, allow engine to run with the throttle
control in the choke (N) position untit the engine runs
roughly, then move throttle Control to fast (,_) position.
This may require an engine warm-up period from
several second._to several minutes, depending on the
temperature.
HYDROSTATIC TRANSMISSION WARM UP
,,
Before driving the unit in cold weather, the transmis-
sion should be warmed up as follows:
°
Be sure the tractor is on level ground_
Place the motion control lever in neutral°
Release the parking brake and let the clutch/brake
slowly return to operating position.
Allow one minute for transmission to warm upo
This can be done during the engine warm up
period.
°
The attachments can also be used during the engine
warm-up period afterthe transmission has been warmed
up.
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
To ensure proper operation and performance, it is recom-
mended that the transmission be purged before operating
tractor for the first time. This procedure will remove any
trapped air inside the transmission which may have devel-
oped during shipping of your tractor.
