MAINTENANCE TRANSAXLE MAINTENANCE The transmission fan and cooling fins should be kept clean to ensure 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 transmission. • 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 authorized service center/department. LOWER DASH COVER FASTENER SLOTS TABS Fig. 15 2. Slide oil drain extension from the docking position on engine blower housing and extend outward from engine. DOCKING POSITION OIL DRAIN EXTENSION 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 5W-30 SAE 30 F -20 0 30 32 40 60 80 100 C -30 -20 -10 0 10 20 30 40 TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE 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. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. 02463 CAP Fig. 16 3. To open, twist cap counter-clockwise 4. After oil is drained completely, replace cap and twist clockwise until it stops. 5. Re-attach oil drain extension to engine blower housing. 6. Refill engine with oil through oil fill dipstick tube. Pour slowly. Do not overfill. For approximate capacity see "PRODUCT SPECIFICATIONS" section of this manual. 7. Use gauge on oil fill cap/dipstick for checking level. For accurate reading, tighten dipstick cap securely onto the tube before removing dipstick. Keep oil at "FULL" line on dipstick. Tighten cap onto the tube securely when finished. 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 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. CLEAN AIR SCREEN TO CHANGE ENGINE OIL (See Fig. 15 & 16) 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. LEFT LOWER DASH COVER REMOVAL • Raise hood. • Remove fastener from left lower dash cover. CAUTION: Remove lower dash cover carefully to ensure cover tabs are not broken. • Slide lower dash cover up to release cover tabs from tapered slots in lower dash and remove. 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. AIR FILTER Your engine will not run properly using a dirty air filter. Service air cleaner more often under dusty conditions. 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. Clean the cooling fins and external surfaces as necessary. Ensure the cooling shrouds are reinstalled. 1. Remove oil fill cap/dipstick. Be careful not to allow dirt NOTE: Operating the engine with a blocked grass screen, to enter the engine when changing oil. dirty or plugged cooling fins, and/or cooling shrouds removed 16 will cause engine damage due to overheating.
