FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. WARNING: In order to prevent accidental starting when setting up, transporting, adjusting or making repairs, always disconnect spark plug wire and place wire where it cannot contact spark plug. WARNING: Do not coast down a hill in neutral, you may lose control of the tractor. [. . . ] 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. CLOSED AND LOCKED POSITION 02 46 3 DRAIN TUBE YELLOW CAP • • • • 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 authorized service center/department. ENGINE LUBRICATION Only use high quality detergent oil rated with API service classification SG-SL. Select the oil’s SAE viscosity grade according to your expected operating temperature. SAE VISCOSITY GRADES SAE 30 5W-30 F C -30 -20 -20 0 -10 30 32 0 40 10 60 20 80 30 100 40 Fig. 16 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. Remove the drain tube and replace the cap onto to the bottom fitting of the drain valve. Refill engine with oil through oil fill dipstick tube. For approximate capacity see “PRODUCT SPECIFICATIONS” section of this manual. Use gauge on oil fill cap/dipstick for checking level. Be sure dipstick cap is tightened securely for accurate reading. Keep oil at “FULL line on dipstick. Tighten ” cap onto the tube securely when finished. ENGINE OIL FILTER Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year. AIR FILTER Your engine will not run properly using a dirty air filter. Service air cleaner more often under dusty conditions. TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE CLEAN AIR SCREEN Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush or compressed air to remove dirt and stubborn dried gum fibers. NOTE: Although multi-viscosity oils (5W30, 10W30 etc. ) improve starting in cold weather, they will result in increased oil consumption when used above 32°F/0°C. 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. ENGINE COOLING SYSTEM To ensure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. Every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing and other cooling shrouds.
