To change the oil, first run the engine for 5 minutes to warm it up. Stop the engine and remove the ignition key. Place a pan under the oil drain valve, open the valve, and allow the oil to drain completely. Replace the oil filter, close the valve, and refill with the recommended oil type and quantity.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content.
Ensure the battery is charged and the terminals are clean. Check the fuel level and ensure the fuel valve is open. Inspect the spark plug for damage or wear. If the problem persists, consult the user manual or contact a service professional.
Blades should be sharpened after every 25 hours of use or whenever you notice a decrease in cutting performance. Always balance the blades after sharpening to ensure smooth operation.
Always remove the key and disconnect the battery before cleaning. Use a garden hose to wash the underside of the deck. Avoid using a pressure washer as it may damage components. Dry the deck thoroughly to prevent rusting.
Ensure the blades are sharp and properly balanced. Adjust the cutting height to the desired level and mow at a steady pace. Regularly clean the underside of the deck to prevent grass buildup.
Perform a general inspection before each use. Change the oil every 50 hours, replace the air filter annually, and sharpen the blades as needed. Refer to the user manual for detailed maintenance intervals.
Locate the cutting height adjustment lever on the mower deck. Move the lever to the desired height setting, ensuring both sides are set equally for an even cut.
This could be due to dull blades or an uneven deck. Check the blade condition and sharpen if necessary. Ensure the deck is level and clear of debris.
Drain the fuel or add a fuel stabilizer to prevent degradation. Change the oil and replace the air filter. Clean the mower thoroughly and store it in a dry, sheltered location. Disconnect the battery to prevent drainage.
