OPERATION
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 GAS O LINE
TO HELP ENSURE GOOD COLD WEATHER START ING.
CAUTION: Alcohol blended fuels (called gas o hol
or using ethanol or methanol) can attract mois-
ture 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 sea son. See Storage In struc 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. 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 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 choke position.
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, 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)
• 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 roughly, then move throttle control to fast posi-
tion. This may require an engine warm-up period from
several seconds to several minutes, depending on the
tem per a ture.
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 position.
• Allow one minute for transmission to warm up. This
can be done during the engine warm up period.
• The attachments can also be used during the engine warm-
up period after the transmission has been warmed up.
NOTE: If at a 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 CARBURETOR” in the Service and Adjust-
ments section of this manual.
