ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do not overfill.
Use fresh, clean, regular un lead ed 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 quan ti ties that can be used within 30 days to
assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GAS O LINE TO HELP INSURE GOOD COLD WEATHER
START ING.
CAUTION: Alcohol blended fuels (called gasohol
or using ethanol or methanol) can attract moisture
which leads to sep a ra tion and for ma tion 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 In struc tions for additional information.
Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
OPERATION
TO START ENGINE (See Fig. 13)
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.
• Be sure freewheel control is in the transmission
en gaged position.
• Sit on seat in operating position, depress brake
pedal and set parking brake.
• Move attachment clutch to “DISENGAGED” position.
• Move throttle control to fast position
• Pull choke control out for a cold engine start at-
tempt. For a warm engine start attempt the choke
control may not be needed.
NOTE: Before starting, read the warm and cold starting
procedures below.
• 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 sec onds 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 control out and retry.
WARM WEATHER STARTING (50° F and above)
• 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)
• 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 engine to accept small changes in speed and
load, until the choke control is fully in. If the en-
gine 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 sec onds to
several minutes, depending on the temperature.
AUTOMATIC TRANSMISSION WARM UP
• Before driving the unit in cold weather, the trans-
mis sion should be warmed up as follows:
• Be sure the tractor is on level ground.
• Release the parking brake and let the brake
slowly return to operating po si tion.
• 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 con trol be
pulled out slight ly.
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
Ad just ments section of this manual.
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine in your tractor has been shipped, from the
factory, already filled with sum mer weight oil.
• Check engine oil with tractor on level ground.
•
Remove oil fill cap/dipstick and wipe clean, reinsert
the dipstick and screw cap tight, 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 Maintenance sec tion of this manual).
• To change engine oil, see the Maintenance section
in this manual.
