4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your PowerSmart lawn mower.

• Engine Oil: Check engine oil level before each use. Change oil according to the engine manufacturer's recommendations (typically after the first 5 hours, then every 25-50 hours).
• Air Filter: Inspect and clean the air filter regularly. Replace if heavily soiled or damaged.
• Spark Plug: Check and clean the spark plug annually. Replace if worn.
• Cutting Blade: Inspect the 21-inch steel blade for sharpness and damage. Sharpen or replace as needed. A dull blade can tear grass, leading to an unhealthy lawn.
• Deck Cleaning: Clean the underside of the steel deck after each use to prevent grass buildup, which can affect cutting performance.
