Craftsman 917.273401 - Manual (Page 15)

• 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 oil, see the Mainte­
nance section in this manual.
ADD GASOLINE
• Fill fuel tank to bottom of tank 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 quanti­
ties that can be used within 30 days to
assure fuel freshness.
A cau TION: Wipe off any 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°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 separa­
tion 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 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
transmission engaged position.
2. Sit on seat in operating position,
depress dutch/brake pedal and set
parking brake.
3. Place motion control lever in neutral
(N) position.
4. Move attachment clutch to disengaged
position.
5. Move throttle control to choke position.
NOTE: Before starting, read the warm
and cold starting procedures below.
6. 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 and
above)
7. 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)
7. 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 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;
1. Be sure the tractor is on level ground.
2. Place the motion control lever in
neutral. Release the parking brake
and let the clutch/brake slowly return
to operating position.
3. Allow one minute for transmission to
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: 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.)
