To start the McCulloch M45H46RDKHW, ensure the fuel tank is filled, the oil level is adequate, and the spark plug is connected. Then, push the primer bulb three times, pull the throttle lever to the fast position, and pull the starter cord firmly.
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content to prevent engine damage.
Change the oil after the first 5 hours of use, and then every 25 hours of operation or at the beginning of each mowing season. Use SAE 30 oil for best performance.
Check the fuel level, ensure the spark plug is connected, and inspect the air filter for clogs. If the problem persists, clean or replace the spark plug and check the fuel line for blockages.
To adjust the cutting height, locate the height adjustment levers on each wheel. Move the levers to the desired position, ensuring all wheels are set to the same height for an even cut.
To sharpen the blades, disconnect the spark plug, tilt the mower to access the blade, and use a wrench to remove it. Sharpen the blade using a file or bench grinder, then reinstall it securely.
After use, turn off the mower and disconnect the spark plug. Use a garden hose to rinse off grass clippings and debris from the deck and wheels. Avoid spraying water directly into the engine.
To winterize, drain the fuel tank or add a fuel stabilizer, change the oil, remove the spark plug and add a few drops of oil into the cylinder, and clean the mower thoroughly before storage.
Excessive vibration may be due to an unbalanced blade, loose parts, or damaged components. Check the blade for damage, tighten all bolts and nuts, and inspect the mower for any signs of wear or damage.
To replace the air filter, locate the air filter cover, remove it, and take out the old filter. Insert a new air filter, ensuring it fits securely, and then replace the cover.
