Should the transaxle ever leak or require servicing, contact your nearest Sears or other qualified service center. V-BELTS CheckV-betts for deterioration and wear after 100 hours of operation and replace if necessary. The belts are not adjustable. Replace belts if they begin to slip from wear. 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. 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. 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. Refill engine with oil through oil fill dipstick tube. Pour slowly. Do not overfill. For approximate capacity see "PRODUCT SPECIFICATIONS"section ofthis manual. 8. Use gauge on oil fill cap/dipstick 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. AIR FILTER Your engine will not run properly using a dirty air filter. Service paper cartridge every two months or every 25 hours of operation, whichever occurs first. Service paper cartridge more often under dusty conditions. Replace the paper cartridge annually, or after every 100 hours of operation.
