Move motion control lever to "NEUTRAL" position 12 OPERATION TO START ENGINE 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 (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 the clutch/brake brake When mowing large areas, start by turning to the right so that clippings will 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) pedal and set the parking Place motion control lever in "NEUTRAL" 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" position. 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. 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 move throttle control lever to desired running speed. Al!ow engine to warm up for a few minutes before engaging motion control or attachment clutch 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 Adjustments section of this manual MOWING FIG, 9 If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clippings. Make first cut relatively high the second to the des red he ght TIPS Do not mow grass when it is wet. Wet grass will plug mower and leave undesirable clumps. Allow grass to dry before mowing 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 Always operate engine at full throttle when mowing to assure better mowing performance and proper discharge of material Regulate ground speed by selecting a low enough speed to give the mower cutting performance as well as the quality of cut desired Use the runner on the right hand side of mower as a guide. The blade cuts approximately an inch outside the runner (See Fig 8). When operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used The !eft hand side of mower should be used for trimming 13 MAINTENANCE u ,,,, _ .........

If you feel they must be lubricated, use only a dry, powdered graphite type lubricant sparingly LUBRICATION Keep unit well lubricated (See "LUBRICATION SAE lOW30 MOTOR OIL API - SR/CC GENERAL PURPOSE GREASE REFER TO ENGINE MAINTENANCE SECTION CHART") 14 MAINTENANCE TRACTOR TO SHARPEN BLADE (See Fig. 11) Care should be taken to keep the blade balance& An unbalanced blade will cause excessive vibration and eventual damage to mower and engine Always observe safety rules when performing any maintenance The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower, TIRES Maintain proper aJr pressure in all tires (See "PRODUCT SPECIFICATIONS" on page 3 of this manual) To check blade balance, drive a nail into a beam orwall. Leave about one inch of the straight nail exposed, Place center hole of blade over the head of the nail. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced, Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber, Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

Allow the engine to cool before storing in any enclosure. TRACTOR Remove mower from tractor for winter storage mower is to be stored for e period of time, clean oughly, remove all dirt, grease, leaves, etc Give and underside of housing a good coat of grease preventative. Store in a clean, dry area. Clean entire tractor (See "CLEANING" nance section of this manual) When it thorblades or rust IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION AND FORMATION OFACIDS DURING STORAGE ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE. Drain the fuel tank Start the engine and let it run until the fuel lines and carburetor are empty, in the Mainte- Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Use fresh fuel next season Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). Lubricate as shown in the Maintenance section of this manual. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage_ Add stabilizer to gasoline in fuel tank or storage container Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear Replace if necessary Touch up all rusted or chipped paint sudaces: sand lightly before painting ENGINE BATTERY OIL Drain oil (with engine warm) and replace with clean engine oil (See"ENGINE" intheMaintenancesectionofthismanual) Fully charge the battery for storage After a period of time in storage, battery may require recharging CYLINDERS To help prevent corrosion and power leakage during long periods of storage, battery cables should be disconnected and battery cleaned thoroughly (see "TO CLEAN BATTERY AND TERMINALS" in the Maintenance sectioin of this manual) Remove spark plug(s) Pour one ounce of oil through spark plug hole(s) into cylinder(s). Turn ignition key to "START" position for a few seconds to distribute oil After cleaning, leave cables disconnected and place cables where they cannot come in contact with battery terminals Replace with new spark plug(s) Be sure battery drain tube Jssecurely attached to drain in battery tray OTHER Do not store gasoline from one season to another Replace your gasoline can if your can starts to rust Rust and/or dirt in your gasoline will cause problems, If possible, store your unit indoors and cover it to give protection from dust and dirt.
