Regular Maintenance Tips

1. Check the Oil
   • Regularly checking and changing the oil is crucial. Old or dirty oil can cause excessive wear on the engine. Check the oil level before each use and change it at least once a season or after every 50 hours of use. Use the type of oil recommended by the manufacturer for best results.
2. Clean the Air Filter
   • A clean air filter ensures your lawn mower runs efficiently. Replace paper filters and wash foam filters with soap and water, then let them air dry. Do this every 25 hours of operation or at the start of each mowing season.
3. Sharpen the Blades
   • Sharp blades cut grass cleanly, promoting healthy growth. Dull blades tear the grass, leaving it vulnerable to disease. Sharpen the blades at least once a year or whenever you notice the grass is not being cut cleanly.
4. Inspect the Spark Plug
   • The spark plug is vital for starting the engine. Inspect it for wear and replace it if necessary, typically once a year. Make sure the gap is set correctly as per the manufacturer's specifications.
5. Clean the Deck
   • Grass clippings and debris can build up under the mower deck, hindering performance. After each use, disconnect the spark plug and use a hose or brush to clean the underside of the mower.
6. Check the Tires
   • Ensure tires are inflated to the proper pressure to achieve an even cut. Uneven tire pressure can result in an uneven lawn.
7. Fuel System Maintenance
   • Use fresh gasoline and add a fuel stabilizer if storing the mower for an extended period. Old fuel can cause starting issues and damage the engine.

DIY Repair Tips

1. Troubleshoot Starting Problems
   • If your mower won't start, check the fuel level, the spark plug, and the air filter. Ensure the fuel is fresh, the spark plug is clean, and the air filter is not clogged.
2. Fixing a Lawn Mower That Won’t Cut Evenly
   • An uneven cut can be due to dull blades, improper tire pressure, or a misaligned deck. Sharpen the blades, check the tire pressure, and refer to the owner's manual to level the deck.
3. Replacing the Drive Belt
   • If your self-propelled mower is not moving as it should, the drive belt might be worn out. Consult the manual for instructions on replacing the belt.
4. Handling Excessive Vibration
   • Excessive vibration can be a sign of an unbalanced blade, loose parts, or a damaged engine. Check and tighten all nuts and bolts, balance or replace the blade, and inspect the engine for any visible damage.

Proactive Care Tips

1. End-of-Season Storage
   • Before storing your mower for the winter, run it until the fuel tank is empty, or add a fuel stabilizer to prevent the fuel from degrading. Clean the mower thoroughly and store it in a dry place.
2. Regular Inspections
   • Conduct a thorough inspection at the start and end of each mowing season. Look for any signs of wear or damage and address them promptly.
3. Follow the Manufacturer’s Manual
   • Always refer to the manufacturer's manual for specific maintenance schedules and repair instructions. This ensures you’re following the best practices for your particular mower model.
