To change the oil, first run the engine for a few minutes to warm it up. Turn off the engine and remove the key. Place a drain pan under the engine, remove the oil drain plug, and allow the oil to completely drain. Replace the drain plug and refill the engine with new oil as per the manufacturer's specifications.
Ensure the battery is charged and properly connected. Check the fuel tank to ensure it has fuel. Verify that the spark plug is clean and properly connected. Make sure the choke is engaged if starting a cold engine.
Blades should be sharpened after approximately every 25 hours of use or whenever you notice a decrease in cutting performance. Ensure the mower is turned off and the blades are cool before attempting to remove and sharpen them.

Ensure the blades are sharp and properly balanced. Check the deck for any buildup of grass or debris, and clean it regularly. Adjust the cutting height according to the grass conditions.
Excessive vibration can be caused by unbalanced or damaged blades. Inspect the blades for damage and balance them if necessary. Also, check for loose bolts or debris stuck in the mower deck.
Clean the mower thoroughly, remove any grass and debris. Drain the fuel or add a fuel stabilizer to prevent degradation. Disconnect the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
Check for any obstructions or debris around the deck lift area. Inspect the lift cables and connections for any damage or disconnection. Ensure the lift mechanism is properly lubricated.
