Murray 42581x95A Parts 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 to let the old oil drain out. Replace the plug and add new oil as specified in the manual.
Check the battery connections to ensure they are clean and tight. Also, make sure there is enough fuel and the fuel valve is open. If it still doesn't start, inspect the spark plug and replace it if necessary.
Regularly inspect the blades for damage and sharpness. Sharpen or replace them as needed. Always disconnect the spark plug before working on the blades for safety.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol.
Check if the blades are properly balanced and sharpened. Also, ensure the tires are inflated equally and the deck is level. Adjust as necessary.
The recommended tire pressure is typically around 10-14 PSI for the rear tires and 14-18 PSI for the front tires. Refer to your manual for exact specifications.
The air filter should be checked and cleaned every 25 hours of use and replaced every 100 hours or annually, whichever comes first.
Stop the engine immediately and allow it to cool down. Check for debris blocking the air vents or cooling fins. Ensure that the oil level is adequate.
Locate the cutting height adjustment lever, usually near the seat or deck. Move the lever to the desired position for the appropriate cutting height.
Regular maintenance includes checking the oil level, inspecting the blades, cleaning the deck, checking tire pressure, and ensuring all nuts and bolts are tight.
