For infrequent use (less than 10 hours per year):

  • Annual tune-up: A yearly check-up is sufficient to ensure everything is in good working order.
  • Mid-season check: Take a quick look at the air filter, spark plug, and blade condition midway through the mowing season.

For moderate use (10-20 hours per year):

  • Twice-yearly tune-up: Perform a thorough check-up before the start of the mowing season and again in the middle of the season.
  • Monthly check: Do a quick visual inspection of the blade, air filter, and fuel lines between each mowing session.

For frequent use (more than 20 hours per year):

  • Quarterly tune-up: Perform a complete tune-up every three months throughout the mowing season.
  • Weekly check: Do a quick visual inspection of the blade, air filter, and fuel lines before each mowing session.
