ADD GASOUNE

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 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 fue! 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 charier products in the fuel tank or permanent damage may occur.

CAUTION: Fill to bottom of gas tank filler neck. Do not overfiJL Wipe off any spilled oH or fuel Do not store, spill or use gasomine near an open flame°

TO START ENGINE (See Fig. 8)

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 clutch!brake pedal aria set parking brake.

Place gearshift lever in neutral (N) position.

®Move attachment clutch to "DISENGAGED" position.

Pult choke control out to choke (1",1)position for cold engine start For warm engine start do not use choke control.

oMove throttle contro to midway between fast (@_)and slow (_) positions.

Insert key into ignition and turn key clockwise to"START" position and release key as soon as eng ne 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, slowly push choke control in. Move throttle control to fast (,_) position.

Allow engine to warm up for a Iew minutes before engaging drive or attachments.

NOTE: If at a high altitude tabove 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' m _ne Service and Adjust- ments section of this manual.

MOWING TIPS

Tire chains cannot be used when the mower housing is attached to unit.

-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. 10).

oThe left hand side of mower should be used for trim- ming.

oDrive so that clippings are discharged onto the area that has been cut. Have the cut area: to the right of the machine. This wilt 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 will discharge away from shrubs, fences, driveways, etco After one or two rounds, mow in the opposite direction making left hand turns until finished (See Fig. 12).

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 height.

oDo not mow grass when it is wet. Wet grass will plug mower and leave undesirable clumps. Allow grass to dry before mowing.

oAlways 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 quaIity of cut desired.

oWhen operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used.
