Oil Fill Cap/Dipstick Engine Refer to the Engine Operator's Manual for all engine maintenance procedures and specific instructions pertaining to your engine. NOTE: Maintenance, repair, or replacement of the emission control devices and systems which are being done at owner's expense may be performed by any engine repair establishment or individual. Warranty repairs must be performed by a Cub Cadet Dealer. Changing the Engine Oil WARNING! If the engine has been recently run, the engine, muffler and surrounding metal surfaces will be hot and can cause burns to the skin. Exercise caution to avoid burns. Change the engine oil every 50 hours or once a season. 1. Run the engine for a few minutes to allow the oil in the crankcase to warm up. Warm oil will flow more freely and carry away more of the engine sediment which may have settled at the bottom of the crankcase. Use care to avoid burns from hot oil. 2. Remove the upper star knob (a) and carriage screw (b) on the right side of the handle. See Figure 6-1. (b) (a) Oil Drain Valve Figure 6-1 3. Pivot the support tube forward to allow room to connect the oil drain hose to the oil drain valve. See Figure 6-1. Figure 6-2 5. Remove the oil fill cap/dipstick from the oil fill tube. 6. Push the oil drain hose provided onto the oil drain port. Route the opposite end of the hose into an appropriate oil collection container with at least a 2.5 quart capacity, to collect the used oil. 7. Pinch the tabs on the oil drain valve, then pull outward to begin draining oil. See Figure 6-2. 8. After the oil has finished draining, push the end of the oil drain valve back in, until the tabs click into place. Re-cap the end of the oil drain valve to keep debris from entering the drain port. 9. Refill the engine with new oil. Refer to the Engine Operator's Manual for information regarding the volume and weight of engine oil. Air Cleaner The air cleaner element should be replaced every 100 hours or once a season. Service the pre-cleaner and cartridge/air cleaner element as instructed in the Engine Operator's Manual. Spark Plug The spark plug should be cleaned and the gap reset every 25 hours or once a season. Refer to the Engine Operator's Manual for correct plug type and gap specifications. Fuel Filter The fuel filter cannot be cleaned and should be replaced every 100 operating hours; more often if run with old gasoline. 18 Section 6 - Maintenance & Adjustments
