To start the mower, ensure the fuel valve is open, set the choke to the 'ON' position, pull the recoil starter handle, and once the engine starts, move the choke to the 'OFF' position.
Check the fuel level and fill if necessary, ensure the spark plug is connected, inspect the air filter for blockages, and verify that the safety key is fully inserted.
Change the oil after the first 5 hours of use, and then every 50 hours or annually, whichever comes first.
Use SAE 30 or 10W-30 detergent oil that is classified for service SF, SG, SH, SJ, or higher.
To adjust the cutting height, locate the height adjustment levers on each wheel and move them to the desired position. Ensure all wheels are set at the same height for an even cut.
Check for debris lodged in the mower deck, ensure the blade is not damaged or unbalanced, and inspect the engine mounting bolts for tightness.
Turn off the engine and disconnect the spark plug, then use a garden hose to rinse off grass and debris from the deck. Avoid using high-pressure water directly on engine components.
Check the air filter before each use and clean or replace it every 25 hours of operation or more frequently in dusty conditions.
Remove the blade from the mower, secure it in a vice, and use a file or grinding wheel to sharpen the blade, maintaining the original angle. Balance the blade before reinstalling it.
Ensure that the blade is sharp and properly balanced, check that all wheels are set to the same height, and inspect for any obstruction under the deck.
