Regular maintenance includes checking and cleaning the air filter, inspecting the spark plug for wear, lubricating the gearhead, and checking the fuel filter for blockages. Always refer to the user manual for specific maintenance intervals and procedures.

Why won't my trimmer start after storage?

If your trimmer won't start after storage, check for stale fuel and replace it with fresh fuel. Inspect the spark plug for fouling and clean or replace it if necessary. Ensure the air filter is clean and check the fuel lines for cracks or blockages.

How do I clean the air filter on the 535LST trimmer?

To clean the air filter, remove the air filter cover and take out the filter. Wash it with warm, soapy water and allow it to dry completely. Apply a small amount of oil to the filter before reinstalling it. Ensure it is seated properly before replacing the cover.

Before storing your trimmer for the winter, empty the fuel tank and run the engine until it stalls to clear any fuel from the carburetor. Clean the trimmer thoroughly and inspect it for any damage. Store it in a dry, cool place away from direct sunlight.

How do I troubleshoot a trimmer that stalls during operation?

If the trimmer stalls during operation, check for a clogged air filter, inspect the fuel filter, and ensure the fuel is fresh. Verify that the spark plug is clean and properly gapped. Also, inspect the exhaust for blockages and clear any debris.
