Poulan 159699 - Manual (Page 13)

OPERATION
ADD GASOLINE
® Fill fuel tank. 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.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32"F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
WARNIMG; Experience indicates that alcohol blended
fuels (cailed 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.
CAUTIOM; Fill to bottom of gas tank
filierrseck, DonotoverflM. Wipe off any
spilled oil or fuel. Do not store* spill or
use gasoline near an open flame.
TO START ENGINE (See Fig. 7)
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 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 (|\|) position.
Mote: 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 and above)
® When engine starts, move the throttle control to the fast
(*%f) 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 (j\j) 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.
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 up.
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: it 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.
