To start the McCulloch 20H107RB Lawn Mower, ensure the fuel tank is filled, the oil level is correct, and the spark plug is connected. Then, engage the safety lever, and pull the starter rope firmly.
Use unleaded gasoline with an octane rating of 87 or higher for optimal performance. Avoid using ethanol blends higher than E10.
Change the oil after the first 5 hours of use, then every 25 hours of operation or at the beginning of each mowing season.
Check the fuel level, spark plug connection, air filter, and ensure the safety lever is engaged. If the problem persists, consult the user manual or a professional technician.
Ensure the mower is off and spark plug is disconnected. Use a brush or hose to remove grass clippings and debris from the deck. Avoid using high-pressure water jets.
Regularly check and change the oil, clean or replace the air filter, sharpen the blades, inspect the spark plug, and clean the mower deck.
Locate the height adjustment levers on each wheel and move them to the desired position to raise or lower the cutting height.
Excessive vibration could be due to an unbalanced or damaged blade, loose parts, or a bent crankshaft. Inspect and replace the blade or tighten any loose components.
Turn off the mower and disconnect the spark plug. Locate the air filter cover, remove it, and replace the old filter with a new one. Secure the cover back in place.
Clean the mower, empty the fuel tank, change the oil, remove the spark plug, and store it in a dry place. Cover it to protect from dust and debris.
