Perform engine oil changes every 100 hours, replace the air filter annually, sharpen the blades as needed, and check tire pressure monthly. Refer to the owner's manual for a detailed maintenance schedule.
Check the battery connections, ensure the fuel tank has fresh gasoline, inspect the spark plug for wear or damage, and confirm the safety switches are engaged.
Use SAE 10W-30 engine oil for optimal performance in most conditions. For extreme temperatures, refer to the owner's manual for specific oil recommendations.
To adjust the cutting height, use the deck lift lever located at the operator's left side. Move the lever to select the desired cutting height from the available positions.
Clean the mower deck, change the oil, stabilize the fuel, remove the battery, and store the mower in a dry area. Cover the mower to protect it from dust and debris.
Safely lift the mower, remove the blade bolts using a wrench, replace with new blades, and tighten the bolts securely. Always wear gloves and follow safety procedures.
Inspect the blades for damage or imbalance, check the mower deck for debris build-up, and ensure all bolts are tightened properly.
Ensure the blades are sharp, adjust the cutting height properly, mow at the right speed, and clean the underside of the deck frequently to prevent grass buildup.
Disconnect the spark plug wire, use a spark plug wrench to remove the old plug, install a new plug with the correct gap, and reconnect the wire.
Immediately stop the engine, check fuel lines and connections for leaks, replace any damaged components, and ensure fittings are secure. Consult a professional if necessary.
