The correct fuel mixture for the Husqvarna 535RXT Brushcutter is 50:1, which means 2.6 ounces of two-stroke oil per gallon of gasoline.
To replace the trimmer line, first turn off the engine and disconnect the spark plug. Remove the trimmer head cover, unwind the old line, and replace it with a new line by following the directional arrows on the spool.
If the brushcutter won't start, check the fuel level and quality, ensure the spark plug is clean and properly connected, and inspect the air filter for blockages.
Regular maintenance should be performed after every 25 hours of use, including checking the air filter, spark plug, and fuel system.
To clean the air filter, remove the air filter cover, take out the filter, and wash it with warm soapy water. Allow it to dry completely before reinstalling.
Use high-quality two-stroke engine oil designed for air-cooled engines, preferably Husqvarna’s own brand of oil, to ensure the best performance and longevity.
To reduce vibration, ensure that the handlebar and cutting attachment are securely fastened, regularly inspect for worn parts, and use anti-vibration gloves.
Always wear protective gear including safety glasses, hearing protection, long pants, gloves, and sturdy footwear when operating the brushcutter.
For off-season storage, empty the fuel tank, clean the brushcutter thoroughly, and store it in a dry, cool place away from direct sunlight.
If the brushcutter is running poorly, check the fuel mixture, clean the air filter, inspect the spark plug, and ensure the carburetor is properly adjusted.
