OPERATION
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
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 screw cap 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 "OIL VISCOSITY CHART" in the
Maintenance section of this manual).
• To change engine oil, see the Maintenance section 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 off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
iMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW
32°F(0°C), 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 the fuel system of an
engine while in storage. To avoid engine problems,
the fuel system should 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
instructions for additional information. Never use
engine or carburetor eJeaner products in the fuel
tank or permanent damage may occur.
TO START ENGINE (See Fig. 3)
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 engaged
position.
• Sit on seat in operating position, depress brake pedal
and set parking brake.
• Move attachment clutch to "DISENGAGED" position.
• Move throttle control to choke position.
NOTE: Before starting, read the warm and cold starting
procedures below.
• Insert key intoignitionand 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 at-
tempts, move throttle control to fast position, wait a few
minutes and try again. If enginestill does not start, move
the throttle control back to the choke position and retry.
WARM WEATHER STARTING (50 ° F/10 ° C 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/10 ° C and below)
• When engine starts, allow engine to run with the throttle
control in the choke position until the engine runs rough-
ly, then move throttle control to fast position. 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:
• Be sure the tractor is on level ground.
• Release the parking brake and let the brake slowly
return to operating position.
• Allow one minute for transmission to warm up. This
can be done during the engine warm up period.
• Theattachmentscan alsobeusedduringtheenginewarm-
up period after the transmission has been warmed up.
NOTE: If at a high altitude (above 3000 feet) or in cold tem-
peratures (below 32 ° F/10 ° C) the carburetor fuel mixture
may need to be adjusted for best engine performance. See
"TO ADJUST CARBURETOR" in the Service and Adjust-
ments section of this manual.
