Maintenance Tips For Your Lawn Mower
Regular Inspection
Check your lawn mower regularly. Look for signs of wear on the primer bulb, hoses, and other parts. Early detection prevents bigger issues down the line.
Clean the Mower
Keep your mower clean. Remove grass clippings and debris after each use. Cleaning helps maintain functionality and extends the life of your mower.
Change Oil
Change the oil every 50 hours of operation or at least once a year. Fresh oil ensures smooth engine performance and prevents buildup.
Replace Air Filter
Inspect the air filter periodically. A clogged filter decreases efficiency. Replace it at least once a season for optimal airflow.

Check Spark Plug
Inspect the spark plug regularly. Replace it if worn or dirty to ensure a proper start every time you mow.
Sharpen Blades
Keep your mower blades sharp. Dull blades tear grass instead of cutting it cleanly. Sharpen blades or replace them as needed, aiming for every 20 to 25 hours of operation.
Follow Safety Guidelines
Prioritize safety. Always wear safety goggles and gloves. Make sure the mower is off and unplugged before performing any maintenance.
Consult the Manual
Refer to your lawn mower’s manual for specific maintenance schedules and recommendations. Each model might require unique care to ensure longevity.
