Poulan Pro CO18542STA Operator's Manual

To change the oil, first run the engine for a few minutes to warm it up. Then, turn off the engine and remove the oil drain plug, allowing the old oil to drain into a pan. Replace the drain plug and refill with new oil as specified in the manual.
Use regular unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol blends higher than E10 to prevent engine damage.
Check the battery connections and ensure they are clean and tight. Verify that there's enough fuel in the tank and the fuel valve is open. Inspect the spark plug and replace it if necessary. Ensure the parking brake is engaged and the blades are disengaged.
The recommended tire pressure is typically around 14 psi for the front tires and 10 psi for the rear tires. Always check the manual for specific recommendations.
The air filter should be checked and cleaned every 25 hours of operation and replaced every 100 hours or annually, whichever comes first. Dusty conditions may require more frequent maintenance.
Locate the cutting height adjustment lever, usually found near the driver's seat. Move the lever to the desired cutting height position, ensuring it locks into place. Refer to the manual for specific height settings.
Disconnect the spark plug wire and use a spark plug wrench to remove the old spark plug. Check the gap on the new spark plug and adjust if necessary. Install the new spark plug and reconnect the wire.
Ensure the PTO (Power Take-Off) lever is in the engaged position. Check the drive belt for wear or damage and replace if necessary. Verify the electrical connections related to the PTO switch and clutch.
Clean the tractor thoroughly and change the oil. Add a fuel stabilizer to the tank and run the engine for a few minutes. Remove the battery and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
Check the oil level, fuel level, and tire pressure. Inspect the air filter and clean if necessary. Ensure the blades are sharp and securely attached. Test the brakes and steering for proper operation.
