Husqvarna MZ 52LE 967 277404-01 Parts Manual

To start the Husqvarna MZ 52LE lawn mower, ensure the parking brake is engaged, place the throttle in the choke position, turn the ignition key to the start position, and release as soon as the engine starts.
If the mower blades do not engage, check the PTO switch to ensure it is in the "on" position, inspect the drive belt for damage or misalignment, and verify that the battery has sufficient charge.
Change the oil in your Husqvarna MZ 52LE after the first 5 hours of operation, and then every 50 hours or at the start of each mowing season thereafter.
The correct tire pressure for the Husqvarna MZ 52LE is typically 15 psi for the front tires and 10 psi for the rear tires. Always refer to the owner's manual for the most accurate specifications.
To improve cutting performance, ensure blades are sharp, clean the deck regularly to prevent buildup, and maintain the recommended engine speed while mowing.
At the end of the mowing season, clean the mower thoroughly, change the oil, inspect and replace the air filter if needed, sharpen the blades, and store the mower in a dry place.
If the engine does not start, check the fuel level, ensure the spark plug is clean and connected properly, verify the air filter is not clogged, and check for loose or damaged wiring.
Use unleaded gasoline with a minimum octane rating of 87 and avoid using gasoline with more than 10% ethanol content to prevent damage to the engine.
Replace the air filter every 100 hours of operation or once per season, whichever comes first, to ensure optimal engine performance.
If the mower vibrates excessively, check for loose or damaged blades, ensure the deck is properly balanced, and inspect the drive belts for signs of wear or misalignment.
