Husqvarna J50 96111001300 Parts Manual

To start the mower, ensure the fuel tank is filled, the spark plug is connected, and the oil level is adequate. Pull the starter cord firmly while holding down the operator presence control bar.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol blends higher than E10 to prevent engine damage.
Change the oil after the first 5 hours of use, then every 25 hours of operation or at the start of each mowing season.
Check for common issues such as an empty fuel tank, dirty air filter, faulty spark plug, or old fuel. Ensure the safety bar is engaged.
Disconnect the spark plug, tilt the mower on its side, and use a hose to wash away grass clippings. Avoid using high pressure to prevent deck damage.
Drain the fuel system, change the oil, clean the mower, and check for any damaged parts that need repair or replacement. Store in a dry, sheltered location.
Sharpen or replace the blade regularly, ensure the grass is dry when mowing, and adjust the cutting height for optimal performance.
Check for a damaged or unbalanced blade, loose engine mounting bolts, or debris lodged in the cutting deck. Address these issues promptly.
Locate the height adjustment levers on each wheel and move them to the desired position. Ensure all wheels are set to the same height for an even cut.
Check for oil spills on the engine surface, ensure the air filter is clean, and inspect the oil level. If the problem persists, consult a professional.
