•Pinch in the lock tabs on the oil drain valve, then pull the drain port outward to begin draining oil. Refer to Figure 24.
•After the oil has finished draining, push the end of the oil drain valve back in, until the tabs click into place.
•Replace the oil filter, and refill the engine with new oil as instructed in the Kohler Owner’s Manual.
Off-Season Storage
If the machine is to be inoperative for a period longer than 30 days, the fol- lowing procedures are recommended:
WARNING: Never store the tractor with fuel in the tank, indoors or in poorly venti- lated enclosures where fuel fumes may reach an open flame, spark or pilot light (e.g.: furnace, water heater, clothes dryer, etc.).
WARNING: Fuel left in the fuel tank deteriorates and will cause serious starting problems.
To prevent gum deposits from forming inside the engine’s carburetor and causing possible malfunction of the engine, the fuel system must be either completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration.
1.If using a fuel stabilizer:
•Read the product manufacturer’s instructions and recommendations.
•Add to clean, fresh gasoline the correct amount of stabilizer for the capacity of the fuel system.
•Fill the fuel tank with treated fuel and run the engine for
2.If emptying the fuel system:
•Near end of the season, monitor fuel consumption with the goal of running the fuel tank to empty.
•If a large volume of fuel is left over, remove the fuel cap and siphon the bulk of any leftover fuel into an approved container.
•Run the engine until it starts to falter, then use the choke to keep the engine running until all fuel in the carburetor has been ex- hausted.
3.Perform the following procedures before storing the machine.
•Remove the spark plugs and pour one (1) ounce of engine oil through the spark plug holes into the cylinders. Install the spark plugs but do not connect the plug wires. Crank the engine two or three revolutions to distribute the oil.
•Clean the engine and the entire tractor thoroughly.
•Lubricate all lubrication points.
•Prepare the battery for storage.
•Protect the tires and seat from sunlight. Regularly check the tires for proper inflation.
NOTE: With the exception of utilizing the deck wash feature on the mower decks, we do not recommend the use of a pressure washer or garden hose to clean your tractor. Water may cause damage to electrical compo- nents; pulleys; bearings; or the engine.
