Ensure the mower is on a flat surface, engage the parking brake, and shift the PTO lever to the off position. Turn the key to start the engine while ensuring the throttle is set to choke or fast position if the engine is cold.
Check the fuel level, battery connections, and spark plug condition. Ensure the PTO is disengaged and the parking brake is engaged. Also, inspect the air filter for clogs.
Blades should be sharpened after every 20 to 25 hours of use or at least once a mowing season to ensure optimal cutting performance.
Perform a general inspection before each use, change the oil every 50 hours, check the air filter every 25 hours, and replace the spark plug annually or every 100 hours.
Ensure the blades are sharp, the deck is clean from grass build-up, and the tire pressure is even and at the recommended levels. Adjust the cutting height according to lawn conditions.
Check for debris or damage on the blades, ensure all bolts are tight, and inspect the spindles and belts for wear or misalignment.
Run the engine for a few minutes to warm up the oil, then turn it off. Remove the oil drain plug and allow the oil to drain completely. Replace the drain plug, add new oil, and check the oil level with the dipstick.
Use SAE 30 oil for temperatures above 32°F (0°C) and 10W-30 for temperatures below that. Always refer to the user manual for specific oil recommendations.
After each use, ensure the engine is off and cool. Lift the deck and use a garden hose to wash away clippings. Scrape off any remaining debris with a plastic or wooden tool to avoid damaging the deck.
Check the tire pressure, ensure the deck is level, and inspect the blades for sharpness and damage. Adjust the deck height if necessary and ensure the blades are correctly installed.
