3. Clean terminals and battery cable ends with wire brush until bright. 4. Coat terminals with grease or petroleum jelly. 5. Reinstallbattery (See "REPLACING BATTERY"in the SERVICE AND ADJUSTMENTSsection 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. o 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 trans- axle ever leak or require servicing, contact your nearest Sears or other qualified service center. 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. TO CHANGE ENGINE OIL Determine temperature range expected before oil change. All oil must meet API service classification SG-SL • 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. Slide oil drain extension from the docking position on the engine blower housing and extend outward from engine.
