To change the oil, ensure the engine is off and cool. Remove the oil drain plug and let the old oil drain into a container. Replace the drain plug and refill the engine with the recommended oil type and quantity.
Check the fuel level and ensure the fuel valve is open. Inspect the spark plug for wear or damage and replace if necessary. Ensure the battery is charged. If the problem persists, consult the user manual or contact a professional.
Blades should be sharpened after every 20-25 hours of use or whenever you notice a decline in cutting performance. Always disconnect the spark plug before removing blades for sharpening.
Use unleaded gasoline with an octane rating of at least 87. Avoid using gasoline with more than 10% ethanol content.
To clean the mower deck, ensure the engine is off and cool. Use a garden hose to rinse off grass clippings and debris. For stubborn dirt, use a soft brush and mild detergent. Avoid using high-pressure washers.
Before storing, clean the mower thoroughly, change the oil, remove the battery, and add a fuel stabilizer to the tank. Store the mower in a dry, sheltered location.
To adjust the cutting height, locate the height adjustment levers near each wheel. Move the levers to the desired position, ensuring all wheels are set to the same height.
Excessive vibration can be caused by imbalanced blades or debris stuck to the deck. Check and clean the blades and deck. Inspect the blades for damage and replace if necessary.
To improve fuel efficiency, regularly maintain the engine by changing the oil and air filter, keep the blades sharp, and ensure the tire pressure is correct. Avoid mowing at full throttle unless necessary.
Check the transmission fluid level and top up if necessary. Inspect the drive belt for wear or damage and replace if needed. If the issue persists, contact a professional for further diagnosis.
