OPERATION
ADD GASOLINE
" Fill fuel tank, Use fresh, clean, regular unleaded
gasoline. (Use of leaded gasoline will increase carbon
and lead oxide deposits and reduce valve life).
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32”F(0”C}, USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING,
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture vrhich 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 iines 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.
A
CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. 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 engine for the first time or if engine has run
out of fuel, it will take extra cranking time to move fuel from
the tank to the engine.
» Depress clulch/brake pedal and set parking brake,
» Place gearshift lever in neutral (N) position,
•
Move attachment clutch to “DISENGAGED" position.
• Move throttle control lever to choke (|\|) position for
cold engine start. For warm engine start, move throttle
control to fast (
4 r) position.
• 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 engine does not start after
several attempts, move throttle control to fast (*^)
position, wait a few minutes and try again.
• When engine starts, move throttle control to desired
position.
» Allow engine to warm up for a few minutes before
engaging drive or attachments.
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 Adjust­
ments section of this manual.
MOWING TIPS
<• Tire chains cannot be used when the mower housing is
attached to tractor,
» Mower should be property ieveied for best mowing
performance. See TO LEVEL MOWER HOUSING" in
the Service and Adjustments section of this manual.
• The left hand side of mower should be used for trim­
ming.
• Drive so that clippings are discharged onto the area
that has been cut Have the cut area to the right of the
machine. This will result in a more even distribution of
clippings and more uniform cutting.
• When mowing large areas, start by turning to the right
so that clippings wiil discharge away from shrubs,
fences, driveways, etc. After one or two rounds, mow
in the opposite direction making left hand turns until
finished (See Fig. 9).
• If grass is extremeiy tail, it should be mowed twice to
reduce load and possible fire hazard from dried clip­
pings. Make first cut relatively high; the second to the
desired height.
• Do not mow grass when it is wet. Wet grass will plug
mower and leave undesirable clumps. Allow grass to
dry before mowing.
• Always operate engine at full throttle when mowing to
assure better mowing performance and proper dis­
charge of material. Regulate ground speed by select­
ing a low enough gear to give the mower cutting
performance as well as the quality of cut desired.
« When operating attachments, select a ground speed
that wiil suit the terrain and give best performance of
the attachment being used.
