Disconnect BLACK battery cable first then RED battery cable and remove batter,/from tractor. 2. Rinsethe battery with plainwaterand dry. 3. Clean terminals and battery cable ends with wire brush until bright. 4. Coat terminals with grease or petroleum jelly. 5. Reinstall battery (See "REPLACING BATTERY" in the SERVICE AND AD- JUSTMENTS section of this manual). TRANSAXLE COOLING The transmission fan and cooling fins should be kept clean to assure proper cooling. Do not attempt to clean fan or transmission while engine is running or while the transmission is hot. To prevent possible damage to seals, do not use high pressure water or steam to clean transaxle. . Inspect cooling fan to be sure fan blades are intact and clean. , Inspect cooling fins for dirt, grass clippings and other materials. To prevent damage to seals, do not use compressed air or high pressure sprayer to clean cooling fins. TRANSAXLE PUMP FLUID The transaxle was sealed at the factory and fluid maintenance is not required for the life of the transaxle. Should the transaxle ever leak or require servicing, contact your nearest Sears or other qualified service center. SAt_ VISCOSITY GRADES ! ii ...... ,'!!!!,!!!! .........

Replace belts if they begin to slip from wear. TO CHANGE ENGINE OIL Determine temperature range expected before oil change. All oil must meet API service classification SG-SL. o Be sure tractor is on level surface. • Oil will drain more freely when warm. , Catch oil in a suitable container. 1. Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil. 2. Removeyellowcapfromendofdrainvatve and install the drain tube onto the fitting. 3. Unlock drain valve by pushing inward slightly and turning counterclockwise. Oil Drain Valve Closed and __ Locked I ,\ Yellow I:Z X-# ENGINE LUBRICATION % _,-'- ./ "Drain Tube Only use high quality detergent oil rated with API service classification SG-SL. Se- lect the oil's SAE viscosity grade according to your expected operating temperature. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°R Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 50 hours of operation or at least once a year if the tractor is not used for 50 hours in one year. Check the crankcase oil level before starting the engine and after each eight (8) hours of operation. Tighten oil fill cap/dipstick securely each time you check the oil level. 4. To open, pull out on the drain valve, 5. After oil has drained completely, close and lock the drain valve by pushing inward and turning clockwise until the pin is in the locked position as shown. 6. Remove the drain tube and replace the cap onto the end of the drain valve. 7. Refillenginewith oilthrough oilfilldipstick tube. Pour slowly. Do not overfill. For approximate capacity see "PRODUCT SPEClFIOATIONS"sectionofthis manual. 8. Use gauge on oil fill captdipstick for checking level. For accurate reading, insert dipstick into the tube and push down firmly into place before removing. Keep oil up to, but not over, the "FULL' line on dipstick. Push dipstick down firmly into the tube when finished. 21
