• Inspect spark plug: Clean, re-gap, or replace if worn for easy starting and smooth running.
• Fuel care: Use fresh gasoline; add stabilizer if storing >30 days to prevent carb clogging.
• Run monthly (“exercise” it): Operate for 10–15 minutes at ~50% load to keep engine healthy.
• Battery (electric start models): Keep charged and terminals clean.
• Cooling & storage: Keep in dry, ventilated place; avoid overheating and moisture exposure.
• Check fuel lines & bolts: Tighten loose parts and inspect for leaks before each use.
