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.

WARNING: Experience indicates that 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 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.

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. 8)

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.

°Sit on seat in operating position, depress clutch_rake pedal and set parking brake,

. Place gear shift lever in neutral (N) position,

°Move attachment clutch to "DISENGAGED" position.

• Move throttle control to choke position.

Note: Before starting, read the warm and cold starting procedures below.,

Insert keyinto 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 afew minutes and try again. Ifengine 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 position.

°The attachments and ground drive can now be used, If the engine does not accept the load, restart the engine

and allow itto warm up for one minute using the choke as described above°

COLD WEATHER STARTING ( 50° F and below)

°When engine starts, allowengine 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 severalminutes, depending on the tem- perature.

°The attachments can also be used during the engine warm-up period,

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 '%0

ADJUST CARBURETOR" in the Service and Adjustments section of this manual_

MOWING TIPS

Tire chainscannot be used when the mower housingis attached to tractor°

°Mower should be properly leveled 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- mingo

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.

oWhen mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etch After one or two rounds, mow in the opposite direction making left hand turns until finished (See Fig. 10)_

oIf grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried ctip- dpingsoMake first cut relatively high; the second to the

esired 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 will suit the terrain and give best performance of the attachment being used.
