OPERATUON

ADD GASOLINE

oFIllfuel 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 tN 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 gasohot 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.,

TO START ENGINE (See Fig, 9)

When starting engine for the first time or if engine has run out of fuel, itwill take extra cranking time to move fuel from the tank to the engine.

oDepress the clutch/brake pedal and set the parking brake.

oPlace gearshift lever in "NEUTRAL" position.

•Move attachment clutch to "DISENGAGED" position.

. Pull choke control out to "CHOKE" position for cold engine start. For warm engine start do not use choke control

oMove throttle control to midway between "FAST" and "SLOW" positions.

°Turn ignition 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° Ifengine does not start after several attempts, move throttle control to "FAST" position, wait a few minutes and try again.

o When engine starts, slowly push choke control in.

•Move throttle control to "FAST" position..

,Allow engine to warm up fora few minutes before

engaging clutch/brake pedal or attachment clutch switch.,

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 properly leveled for best mowing

performance. See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual_

•Use the runner on the right hand side of mower as a guide. The blade cuts approximately an inch outside the runner (See Fig. 11),.

oThe 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 tractor. 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 wil! 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.. 13)..

=If grass is extremely tall, 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 heighL

°Do not mow grass when it is wet. Wet grass will plug mower and leave undesirable dumps. 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 tow 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_
